Genome-wide association studies of salinity tolerance in local aman rice.

The present study aimed to identify and characterize new sources of salt tolerance among 94 rice varieties from varied geographic origins. The genotypes were divided into five groups based on their morphological characteristics at both vegetative and reproductive stages using salinity scores from the Standard Evaluation System (SES). The experiment was designed as per CRD (Completely Randomized Design) with 2 sets of salinity treatments for 8 dS/meter and 12 dS/meter, respectively compared with one non-salinized control set. Using a Soil Plant Analysis Development (SPAD) meter, assessments of the apparent chlorophyll content (greenness) of the genotypes were done to comprehend the mechanism underlying their salt tolerance.  To evaluate molecular genetic diversity, a panel of 1 K RiCA SNP markers was employed. Utilizing TASSEL 5.0 software, 598 filtered SNPs were used for molecular analysis. Whole-genome association studies (GWAS) were also used to investigate panicle number per plant (pn, tiller number per plant (till), SPAD value (spad), sterility (percent) (str), plant height (ph) and panicle length (pl. It is noteworthy that these characteristics oversee conveying the visible signs of salt damage in rice. Based on genotype data, diversity analysis divided the germplasm groups into four distinct clusters (I, II, III and IV). For the traits studied, thirteen significant marker-trait associations were discovered. According to the phenotypic screening, seven germplasm genotypes namely Koijuri, Asha, Kajal, Kaliboro, Hanumanjata, Akundi and Dular, are highly tolerant to salinity stress. The greenness of these genotypes was found to be more stable over time, indicating that these genotypes are more resistant to stress. Regarding their tolerance levels, the GWAS analysis produced comparable results, supporting that salinity-tolerant genotypes having minor alleles in significant SNP positions showed more greenness during the stress period. The Manhattan plot demonstrated that at the designated significant SNP position, the highly tolerant genotypes shared common alleles. These genotypes could therefore be seen as important genomic resources for accelerating the development and release of rice varieties that are tolerant to salinity.

Seedless okra pod, chlorophyll, vitamin C and mineral content development using plant growth regulator in vitro and in vivo culture.

Vegetables are rich in vitamins, minerals and dietary fiber that keep a significant role in the functioning of the human body to refrain human health benefits. The experiment was carried out to investigate the effect of different concentrations of IAA on the seedless pod, chlorophyll, vitamin and mineral content of okra as human health benefits. The innovative seed soaking method of application using 0, 25, 50, 100 & 200 mg/l of IAA concentrations was used in okra before germination and cultured in vitro and in vivo. The lower concentrations (25 and 50 mg/l) of IAA significantly increased the pod setting compared to the higher concentration (100 and 200 mg/l). The higher concentration (100 and 200 mg/l) had lower fruit settings than the lower concentration (25 &50) had higher fruit settings. The higher pod size was obtained in the concentration of 100 & 200 mg/l of IAA (34.18 cm²) as compared to the control and other concentrations. In addition, the highest soluble solid content was obtained by 100 and 200 mg/l of IAA concentration as compared to the other concentrations. The maximum vitamin C was found in the concentration of 100 mg/l of IAA as compared to the control and other concentrations. Moreover, higher mineral contents like K, Ca, Mg, Na and Fe were found in 100 & 200 mg/l of IAA. The higher concentrations (100 and 200 mg/l) of IAA greatly increased the seedless okra percentage as compared to the lower concentration. It seemed that 100 and 200 mg/l concentration IAA was a better concentration for mineral content and seedless okra production as compared to the other concentrations.

The application of nano-hydrogels and hydrogels in wound dressings.

Wounds and the healing process are one of the main concerns of medical science today. A wound is any loss of integrity, or rupture of the layers of skin (epidermis, dermis, and hypodermis) or subcutaneous tissue caused by physical factors (surgical incision, trauma, pressure, and gunshot wounds) or chemical factors (acid burns). It is observed that soft tissue, muscle, or bone is involved in occurrences of wounds. Lesions and fractures of the skin surface necessitate medical attention, wherein dressings expedite the healing process by establishing a physical barrier between the wound and the external environment, thereby preventing further injury or infection. Hydrogel dressings create a moist environment that facilitates common healing steps, such as granulation hyperplasia, epidermal repair, and removal of excess dead tissue. The limited adhesion of the hydrogel and the hydrated wound bed allows for easy removal of the dressing without secondary damage, thereby significantly reducing the discomfort and risk of infection during dressing changes. These modern, wet dressings foster a moist healing environment by absorbing excess inflammatory secretions and allowing proper passage of steam and air, which expedites the healing process. In this analysis, the utilization of hydrogels as wound dressings is briefly presented.

Callus cell and explants regeneration, glucose, mineral, antioxidant and flavonoid content development using broccoli root tip and leaf cutting in vitro.

The study was conducted to evaluate the root, shoot and leaf callus cell regeneration and its biochemical properties like antioxidant, carbohydrate, pigment and mineral content from broccoli root, shoot and leaf cutting in vitro. An in vitro factorial experiment was carried out based on a Completely Randomized Design (CRD) with 5 replicates in tissue culture applying different IBA (0.25, 0.5, 1.0, 1.5, 2.0, 2.5, 3.0 and 3.5 mg/l) and BAP (1 mg/l) concentrations using broccoli root tip and leaf cutting. The results showed that a higher callus weight was found in the cultured leaf cutting than in root tip cutting in the concentration of 1.0, 1.5 & 2.0 mg/l IBA + 1.0 mg/l BAP combination. The highest callus weight was found in the cultured leaf cutting than root tips cutting at the concentration of 1.5mg/l IBA+1.0 mg/l BAP. Furthermore, the highest inverted sugar and glucose, chlorophyll and nutrient content (K+, NO3- & Ca++), total phenol, flavonoid and total antioxidant were found in the concentration of 1.5mg/l IBA+1.0 mg/l BAP combination in both broccoli leaf and root cutting. The results seemed that it was best to use the combination of the IBA and BAP in the concentration of 1.0-2.0 mg/l and 1mg/l to regenerate root, leaf and callus cell proliferation of broccoli from the root tip and leaf cutting.

Control of erucic acid biosynthesis in Camelina (Camelina sativa) by antisense technology.

Oil seeds now make up the world's second-largest food source after cereals. In recent years, the medicinal- oil plant Camelina sativa has attracted much attention for its high levels of unsaturated fatty acids and low levels of saturated fatty acids as well as its resistance to abiotic stresses. Improvement of oil quality is considered an important trait in this plant. Erucic acid is one of the fatty acids affecting the quality of camelina oil. Altering the fatty acid composition in camelina oil through genetic manipulation requires the identification, isolation, and cloning of genes involved in fatty acid biosynthesis. The Fatty Acid Elangase 1 (FAE1) gene encoded the enzyme ß-ketoacyl COA synthase (KCS), which is a key factor in the biosynthesis of erucic acid. In this study, isolation and cloning of the FAE1 from the Camelina sativa were performed to prepare an antisense structure.  The fragments were isolated from the DNA source of the genomic Soheil cultivar with an erucic acid content of about 3% (in matured seeds) using PCR. After cloning FAE1 into the Bluescriprt II SK+ vector and sequencing, these fragments were used for the preparation of antisense structure in the pBI121 plant expression vector. The approved structure was transferred to the camelina plant via the Agrobacterium-mediated method. Also, the conditions of tissue culture and gene transfer were optimized. Moreover, the erucic acid content of the immature seeds of T0 transgenic plants was analyzed with gas chromatography (GC). Results showed significant changes in erucic acid levels of two control plants (0.88%), while two lines of the RFAE1 transgenic plants showed a decrease of approximately 0% in erucic acid level. It can be concluded that the antisense structure can be effective in reducing erucic acid.

Interaction of iron and zinc fortification and late-season water deficit on yield and fatty acid composition of Dragon's Head (Lallemantia iberica L.).

Dragon's head (Lallemantia iberica) is a rich source of alpha-linolenic acid, linoleic acid, essential oil, protein, and mucilage. Therefore, the aim of this study was to evaluate the effects of foliar application of three different concentrations of Fe and Zn (control, 4, and 8 g lit-1) at two different developmental stages (vegetative stage (VS) and reproductive stage (RS)) on the quantity and quality of dragon's head seed yield and fatty acid composition in two crop seasons (2018 and 2019) under two environments (normal irrigation as control (NI) and post-anthesis water deficit (WD). In NI, average yields of seed, oil, and protein were 1155, 340, and 183 kg ha-1, respectively, and in the WD, they were 879, 283, and 148 kg ha-1, respectively. By applying Zn and Fe, the mean values of seed, oil, and protein yields in the NI were 1425, 478, and 264 kg ha-1, while in the WD, they were 1011, 354, and 200 kg ha-1, respectively. Furthermore, the application of WD resulted in a significant increase in zinc concentration, protein percentage, and saturated fatty acid percentage in seeds. Unlike WD, iron and zinc treatments decreased the percentage of saturated fatty acids and increased the percentage of unsaturated fatty acids. The number of capsules per plant had the most positive indirect effect on grain yield. The results showed that foliar spraying of Fe and Zn could effectively mitigate the adverse effects of WD on the quality and quantity of seed and oil yield dragon's head.

Glycyrrhizic acid delivery system Chitosan-coated liposome as an adhesive anti-inflammation.

Nowadays, medicinal plants are used to overcome the side effects of prescription drugs in modern medicine. Glycyrrhizic acid (GA) derived from the root of the licorice plant is one of the plant compounds whose effectiveness has been confirmed in the treatment of inflammatory bowel disorders (IBD). Liposome thin film hydration method was used to synthesize chitosan-coated liposomes containing GA. In the present study, chitosan-coated liposome was characterized by dynamic light scattering (DLS), zeta potential, scanning electron microscope (SEM) and Fourier transforms infrared spectroscopy (FTIR). The FTIR spectrum confirmed the coating of liposomes by chitosan polymer.  Liposome coating leads to an increase in the size and values of zeta potential. The 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay of chitosan-coated liposomes containing GA confirmed that it has no cytotoxicity toward fibroblasts cell line, therefore confirming their cytocompatibility. Overall, drug loading, release and cytotoxicity were evaluated and it was found that chitosan decreased the release rate of GA. It seems; chitosan-coated liposomes may be a suitable system for delivering liposomal GA in the treatment of IBD.

Genetic Characterizations of the Iranian Honey Bee (Apis mellifera meda Skorikov 1929) Populations Using the Microsatellite DNA Markers.

The genetic characterization of the Iranian honey bee was investigated by analyzing 10 polymorphic DNA microsatellite loci in 300 honey bee samples representative of twenty Iranian provinces. This study evaluated the heterozygosity (Ho and He), the Shannon index, the number of observed alleles, and F-statistics among tested populations as genetic parameters. Our finding demonstrated that the Iranian honey bee populations were described by low genetic diversity in terms of the number of observed alleles, Shannon index, and Heterozygosity values. Most populations had significant deviations from Hardy Weinberg equilibrium cause of heterozygote shortage. Low FST and FIS values proposed the absence or very low genetic diversity within and among A. m. meda populations in the present study. The cluster analysis has categorized the honey bee samples gathered from various regions of Iran into two main groups, including honey bees in the North-West (i.e., North, Northwest, and West) provinces and honey bees in the East-South (i.e., Eastern North, Central part, and Southern) provinces of Iran. Our results also revealed lower genetic differentiation and heterozygosity among tested honey bee populations. The results from this study are consistent with previous investigations in Iran, alarming the loss of genetic diversity in the Iranian honey bee populations, which leads to more homozygosity. This study presented new data and reports on genetic structure in investigated native Iranian honey bee populations, and it will benefit future studies on selection, native biodiversity preservation and other conservation breeding projects.

Assessment of ACC and P450 Genes Expression in Wild Oat (Avena ludoviciana) in Different Tissues Under Herbicide Application.

Target-site resistance (TSR) and non-target-site resistance (NTSR) to herbicides in arable weeds are increasing rapidly all over the world and threatening universal food safety. Resistance to herbicides that inhibit ACCase activity has been identified in wild oat. In this study, expression of ACC1, ACC2, CYP71R4 and CYP81B1 genes under herbicide stress conditions were studied in two TSR (resistant in the residue Ile1781-Leu and Ile2041-Asn of ACCase) biotypes, two NTSR biotypes and one susceptible biotype of A. ludoviciana for the first time. Treated and untreated biotypes with ACCase-inhibitor clodinafop propargyl herbicide were sampled from the stem and leaf tissues at 24 h after treatment. Our results showed an increase in gene expression levels in different tissues of both types of resistance biotypes that occurred under herbicide treatment compared with non-herbicide treatment. In all samples, the expression levels of leaf tissue in all studied genes were higher than in stem tissue. The results of ACC gene expression showed that the expression level of ACC1 was significantly higher than that of ACC2. Also, expression levels of TSR biotypes were higher than NTSR biotypes for the ACC1 gene. For both CYP71R4 and CYP81B1 genes, the expression ratio increased significantly in TSR and NTSR biotypes in different tissues after herbicide treatment. In contrast, the expression levels of CYP genes in NTSR biotypes were higher than in TSR biotypes. Our results support the hypothesis that the reaction of plants to herbicide is carried out through a different regulation of genes, which can be the result of the interaction of resistance type in the target or non-target-site.

Stem cell induction and plant regeneration are affected by medium components in maca (Lepidium meyenii Walp).

BACKGROUND: In medicinal plants, selection, reproduction and preservation of important genotypes are very necessary. Nowadays, using tissue culture and regeneration techniques of medicinal plants under in vitro conditions has been able to proliferate medicinal plants widely, which is much higher than traditional methods of vegetative propagation. Maca (Lepidium meyenii), is an industrial plant whose root is the usable part. Maca has valuable medicinal effects such as sexual enhancement and reproductive power, infertility treatment, improved sperm count and quality, anti-stress, osteoporosis prevention and more. METHODS AND RESULTS: This study was conducted to induce callus and regeneration of Maca. First, MS medium supplemented with different concentrations of Kinetin, Naphthaleneacetic acid and 2,4-Dichlorophenoxyacetic acid [0.5, 1 and 2 µM respectively] and control were compared for callus induction from root and leaves. After 38 days of incubation, the first callus appeared, after 50 days of callus induction and after 79 days regeneration occurred. The callus induction experiment was performed for the study of the effect of three explants (leaf, stem and root) and seven hormone levels. The regeneration experiment was carried out by studying the effect of three explants (leaf, stem and root) on eight levels of the hormone. The results of data analysis on callus induction showed that the effects of explants, hormones and their interactions on callus induction percentage were highly significant but not significant on callus growth rate. The results of regression analysis showed that explants, hormones and their interactions had no significant effect on regeneration percentage. CONCLUSION: Based on our results, the best medium for inducing callus was Hormone 2,4-D [2 µM] and Kinetin [0.5 µM], in which the highest percentage of callus induction was in leaf explants (62%). And the lowest were in stem (30%) and root (27%) explants. According to the comparison of the mean, the best environment for regeneration of the environment was 4 µM 6-Benzylaminopurine 2.5 + Thidiazuron, in which the highest percentage of regeneration was in leaf explant (87%) and stem (69%) and the lowest in root explant (12). %).

Transcriptome analysis of gall oak (Quercus infectoria): De novo assembly, functional annotation and metabolic pathways analysis.

Gall oak (Quercus infectoria) is a native tree of Iran, whose gall extract is used to treat many diseases. The presence of abundant secondary metabolites with various bioactivities in this plant has made it medically important. Despite its medicinal value, due to the lack of genomic information, the biosynthetic pathways of these compounds in this species are still unknown. The current research was aimed at observing, characterizing, and investigating the biosynthetic pathways of these compounds in Q.infectoria. De novo transcriptome assembly was conducted using the RNA sequencing technique. A total of 89,335 unigenes were generated, of which 6928 unigenes showed differential expression in leaves compared to root tissue. Gene ontology examination of DEGs revealed GO-term enrichment was related to cellular processes and enzyme activity. KEGG enrichment analysis for DEGs showed that most unigenes were related to metabolic pathways and biosynthesis of secondary metabolites. Moreover, 39 families of transcription factors were identified, of which the C2H2, bZIP, bHLH, and ERF TFs had the highest frequency. In the absence of a reference genome, the overall study of transcriptome will provide a reference for future functional and comparative studies. Moreover, the data obtained from sequencing and de novo assembly can be a valuable scientific resource for Q.infectoria.

Phytosomes: A promising delivery system for anticancer agents by using phytochemicals in cancer therapy.

Plant extracts have been shown to be effective in treating a variety of ailments; however their hydrophilic nature and unique chemical structure have caused significant hurdles due to their low bioavailability. Phytosomes technology is used to improve the absorption of phytoconstituents that are difficult to absorb. Among the leading deaths in the society is malignancy. The aforementioned consumes remained a big issue for modern chemotherapy since it has yet to be treated in an efficient manner. The goal of this study is to outline the most recent research on the potential use of phytosome complexes for cancer therapy, as well as the formulation processes and mechanism of transportation through phytosomes.Nanotechnology has paved the way for cancer therapy by altering key features of medications and their carriers. Novel drug delivery systems are used to transfer antitumor drugs to the particular site via different nanostructures. Among several unique drug delivery systems, phytosomes are a creative way to transfer phytoactive compounds to the site of action, and several phytosomes formulations are now being used in clinical settings. Phytoconstituents' anti-cancer activities are increased by phytosomal formulations.

Biochemical and Transcriptional Responses in Cold-Acclimated and Non-Acclimated Contrasting Camelina Biotypes under Freezing Stress.

Cold-acclimated and non-acclimated contrasting Camelina (Camelina sativa L.) biotypes were investigated for changes in stress-associated biomarkers, including antioxidant enzyme activity, lipid peroxidation, protein, and proline content. In addition, a well-known freezing tolerance pathway participant known as C-repeat/DRE-binding factors (CBFs), an inducer of CBF expression (ICE1), and a cold-regulated (COR6.6) genes of the ICE-CBF-COR pathway were studied at the transcriptional level on the doubled-haploid (DH) lines. Freezing stress had significant effects on all studied parameters. The cold-acclimated DH34 (a freezing-tolerant line) showed an overall better performance under freezing stress than non-acclimated plants. The non-cold-acclimated DH08 (a frost-sensitive line) showed the highest electrolyte leakage after freezing stress. The highest activity of antioxidant enzymes (glutathione peroxidase, superoxide dismutase, and catalase) was also detected in non-acclimated plants, whereas the cold-acclimated plants showed lower enzyme activities upon stress treatment. Cold acclimation had a significantly positive effect on the total protein and proline content of stressed plants. The qRT-PCR analysis revealed significant differences in the expression and cold-inducibility of CsCBF1-3, CsICE1, and CsCOR6.6 genes among the samples of different treatments. The highest expression of all CBF genes was recorded in the non-acclimated frost-tolerant biotype after freezing stress. Interestingly a significantly higher expression of COR6.6 was detected in cold-acclimated samples of both frost-sensitive and -tolerant biotypes after freezing stress. The presented results provide more insights into freezing tolerance mechanisms in the Camelina plant from both a biochemical point of view and the expression of the associated genes.

The Effects of Nanosilver on Bacterial Contamination and Increase Durability Cultivars of Rosa hybrida L. Through of Stenting Method.

The rose flower (Rosa hybrida L.) is one of the world's most popular flowers among ornamental plants and the cut rose flower industry is the most important aspect of the rose culture industry in the world. The stenting method (cutting and grafting) uses a stem containing a leaf and a dormant bud as a scion, which is grafted onto an internode from the rootless rootstock so that the formation of the graft and the induction of the root on the rootstock are carried out simultaneously. In this method, Natal Briar is often used due to its desirable traits such as high rooting, the possibility of faster regeneration after cutting, the ability to adapt to different culture media and high resistance to root diseases. Most imported Natal Briar rootstocks, in addition to increasing the cost of producing hybrid roses, have a percentage of Agrobacterium contamination that can reduce the efficiency of stenting. Therefore, using the tissue culture technique to propagate the base is one of the important solutions. But one of the problems of tissue culture is the control of bacterial contamination so that these factors grow faster than explants and absorbing carbohydrate sources from the culture medium prevents regeneration of Natal Briar rootstocks. Nanotechnology today has expanded the field of application of nanomaterials due to the increase in the surface-to-volume ratio, electron transfer ability and surface reaction capability. Inhibit DNA replication and destroy the cellular structure of Agrobacterium. Therefore, the use of appropriate concentrations of Nanosilver in the culture medium of Natal Briar rootstocks increases the economic efficiency and durability of Rosa hybrida cultivars obtained by the stenting method.

Preparation and characterization of chloridazon-loaded alginate/chitosan nanocapsules.

In addition to the detrimental environmental effects of herbicides, including the pollution of soil, atmosphere, groundwater aquifers and run-off water, the lack of caution and direct or indirect exposure to these products can cause short-term and long-term human health effects. However, nanotechnology, with its many applications, can be very helpful in improving agriculture and reducing the side effects of chemicals used in agriculture. Nano-encapsulation of chemicals used in agriculture is one of the strategies to improve precision agriculture. Nano-encapsulated herbicides are controlled membrane systems in which the active ingredient is coated with semi-permeable membranes, which may be organic or inorganic polymers. In our study, chloridazon herbicide was selected as the active ingredient for Nano-encapsulation. Like many other agricultural herbicides, the major problem with this herbicide is environmental pollution and its adverse health effects. The ionic gelation method was used to synthesize nanocapsules consisting of alginate and chitosan for chloridazon encapsulation. Alginate-chitosan nanoparticles were prepared in a two-step process involving the ionotropic pre-gelation of an alginate core and then the formation of a chitosan polyelectrolyte complex. The alginate-chitosan nanocapsules containing chloridazon were synthesized at a size of 253 nm with a polydispersity index (PDI) of 0.266 and a zeta potential of -1.43 mV. The loading capacity and entrapment efficiency of these nanocapsules were 14% and 57%, respectively. The study of chloridazon release from formulated alginate-chitosan nanocapsules was performed using dialysis tube testing and UV spectroscopy. The results of our study showed controlled release of chloridazon from loaded alginate-chitosan nanocapsules. In general, alginate-chitosan nanocapsules as a Nano-carrier, have the potential to become a commercial formulation for chloridazon encapsulation. On the other hand, controlled release and increasing the duration of action of chloridazon, along with reducing the required dose, is promising in reducing the adverse health and environmental effects caused by chloridazon and improving precision agriculture.

Antibacterial and wound healing applications of curcumin in micro and nano-scaffolds based on chitosan, cellulose, and collagen.

About 80% higher risk of amputation resulted from microbial infection was indicated for patients with diabetic foot ulcers (DFUs). Micro and nano-scaffolds made of natural polymers specifically cellulose, chitosan, and collagen can donate the biocompatibility, biodegradability, and bioavailability properties appropriate to  accelerate wound closure before microbial biofilm formation. Antimicrobial activity of these wound dressings can be improved by incorporation of bioactive compounds extracted from medicinal plant species such as curcumin. Low water solubility and poor bioavailability are recognized as two main disadvantages of curcumin, lipophilic phytopolyphenol, which could be controlled by targeted polymeric micro and nano-scaffolds. Consequently, this review has discussed the capacity and challenges of these types of formulations according to recent investigations.

Molecular and Biochemical Evaluation of Ethyl Methanesulfonate-Induced Mutant Lines in Camelina sativa L.

Background: Camelina sativa is one of the most important oilseeds that has a proportionate profile of essential unsaturated fatty acids that are suitable for human nutrition. In this regard, we can mention a high percentage and a reasonable ratio of omega 3 and omega 6. Objectives: In the current study, the created variation of second-generation mutant (M2) camelina lines in terms of fatty acid profiles and ISSR molecular markers in C. sativa was evaluated. Materials and Methods: For this purpose, while producing the first-generation of mutant plants (M1), 200 M2 seeds with 0.1% and 0.5% ethyl methanesulfonate (EMS) mutations were treated in two replications for 8 and 16 hours based on a completely randomized design. Results: The results of mean comparisons showed that there was no significant difference between treatments in terms of fatty acids of palmitic acid, stearic acid, linoleic acid, eicosadienoic acid, oleic acid and erucic acid. The cluster analysis revealed that all the treatments used with five replications were divided into eight groups. It was found that all replications of the treatment with a concentration of 0.1% and a time of 16 hours (C1T2) were in the second group with the lowest palmitic acid was present among other treatments. Therefore, C1T2 treatment is recommended as the best treatment to reduce palmitic acid. Examination of the information content of ISSR molecular markers also showed that markers 2, 5, and 6 were the best informative markers in the detection of camelina fatty acid profiles. Conclusion: A significant variation has been created in the fatty acids profile and it can be applied in future breeding programs depending on the intended purpose.

Physicochemical properties, nutrient profile, microbial stability, and sensory evaluation of cupcakes enriched with pomegranate seed oil.

Excessive use of refined flour, solid fats, and sugar in preparing baked products are considered to be unhealthy and is intricately linked with the development of lifestyle diseases. Replacing refined flour with whole wheat flour and solid fats with cold-pressed oil serves as an alternate option. The study was aimed at evaluating the physicochemical properties, nutrient composition, sensory attributes, and shelf life of cupcakes enriched using pomegranate seed oil (PSO). Vanilla and chocolate cupcake variants were prepared using 25 and 50% of PSO. A sensory panel consisting of 30 semi-trained participants was selected for evaluating the formulated products using a five-point hedonic scale. Nutrient content was estimated using standard techniques. The stability of the formulated product was determined by evaluating the physicochemical traits and microbial growth on the 0th, 4th, and 7th day. Mean scores of the sensorial analysis showed that the incorporation of PSO in cupcakes was highly accepted by the panel members. Chocolate cupcake containing 50% of PSO was found to be the most preferred product (3.53±0.94), followed by vanilla cupcake containing 25% of PSO (3.4±0.62). The moisture, protein, and fat content of chocolate cupcakes containing 25% of PSO were high. Cupcakes prepared with PSO can be stored for four days at room temperature. GC-MS analysis showed the presence of punicic acid, oleic acid, tocopherols, campesterol, sitosterols, stigmasterol, and α-tocopheryl acetate as pre-dominant fatty acid in unheated and heated PSO. In conclusion, cupcakes prepared using PSO showed acceptable physicochemical qualities and sensory properties which indicated its successful consumption by people affected with metabolic disorders.
