Angiotensin-converting enzyme I/D gene polymorphism and risk of type 2 diabetes mellitus in Iranian individuals.

This study aimed to examine the relationship between type 2 diabetes mellitus (T2DM) and renin-angiotensin system gene polymorphisms in the Iranian population. Additionally, we performed a straightforward meta-analysis of the present articles to better understand this role. A total of 100 Iranian individuals, 50 patients with T2DM, and 50 age-matched healthy individuals were included in this study. DNA was extracted using the salting-out approach, polymerase chain reaction was used to amplify the angiotensin-converting enzyme (ACE) gene, electrophoresis techniques were used, and genotyping was performed. We also searched PubMed, Web of Science, Scopus, and Google Scholar databases for papers published in 2023. We found a significantly higher frequency of I/D genotype in the patient group than in the control group, and the risk of T2DM was 10 times higher in individuals with the I/D genotype (OR, 10 [95% CI, 3.7 to 27]; p < 0.0001) and also 2.85 time higher in individuals with the D allele OR, 2.85 [95% CI, 1.55 to 5.24]; p < 0.001). The ACE polymorphism alleles D and I/D genotypes may increase the risk of developing T2DM in an Iranian population.

The efficacy of colchicine as an adjunct therapy in non-hospitalized COVID-19 patients: A randomized placebo-controlled trial.

BACKGROUND: The therapeutic potential of oral colchicine administration may help combat COVID-19 infection due to reduced disease severity and mortality risk. OBJECTIVE: This randomized trial aimed to assess the effect of colchicine treatment on the inflammatory and hematologic markers as well as clinical features in non-hospitalized patients with mild-to-moderate COVID-19 disease. METHODS: In the present placebo-controlled randomized trial, 80 non-hospitalized COVID-19 patients were enrolled and followed for 14 days. Subjects randomly received oral colchicine or placebo tablets once a day for two weeks. The fever and cough clinical signs, as well as C-reactive protein (CRP) and lymphopenia, were evaluated through the follow-up. RESULTS: No significant between-group differences were observed in terms of the duration of clinical symptoms, CRP, and lymphopenia at 0, 7, and 14 days of intervention. Although the proportion of participants with fever, cough, positive CRP, and lymphopenia was higher reduced in the colchicine group than the placebo during treatment, no significant differences were found between groups. Due to no adverse effects detected in this trial, colchicine therapy was well-tolerated and safe. CONCLUSION: Our findings revealed that colchicine adjuvant therapy had no beneficial effect on clinical and para-clinical parameters in non-hospitalized COVID-19 patients during 14 days of intervention. The present trial does not support colchicine as a potential treatment against COVID-19 disease.

Background and Objective: Rheumatoid arthritis is an autoimmune disease that causes joint pain and reduces daily activities. The aim of this study was to evaluate the serum of vitamin D and its relationship with the severity of the disease in patients with rheumatoid arthritis referred to Allameh Hehlool hospital in Gonabad. Design and Methods: This cross-sectional-analytical study was performed on 92 patients referred to the rheumatology clinic of Allameh Behlool Gonabad Hospital in 2021. After obtaining the permission of the ethics committee, the samples were selected based on the desired criteria. Serum vitamin D levels in patients were measured, and data were collected using a patient information checklist and DAS28-CRP activity questionnaire. Data were analyzed using SPSS software version 16 and using statistically appropriate tests at a significance level less than 5%. Results: The mean age of the patients was 53.05 ± 12.33 years and most of them (58.7%) were women. Serum vitamin D level was sufficient in 65.2% of patients and the severity of the disease was in the remission in 48.9% of them. The results of chi-square test showed a significant relationship between serum vitamin D levels and disease severity in patients (P < .001). Conclusions: Serum vitamin D levels were inversely related to disease severity and in most patients with severe disease severity, serum vitamin D levels were inadequate. vitamin D supplementation is recommended in patients with rheumatoid arthritis.

Atorvastatin Efficacy in the Management of Mild to Moderate Hospitalized COVID-19: A Pilot Randomized Triple-blind Placebo- controlled Clinical Trial.

BACKGROUND: Statins are first-line lipid-lowering agents with tolerable adverse reactions, low cost, and high availability worldwide. The potent anti-inflammatory, antioxidant, anti-thrombotic and immunomodulatory effects of statins propose them as an option against COVID-19 infection. OBJECTIVE: In this randomized triple-blind placebo-controlled clinical trial, we have investigated the atorvastatin efficacy in the management of mild to moderate hospitalized COVID-19 patients. METHODS: In this study, 52 mild to moderate hospitalized COVID-19 patients who fulfilled the inclusion criteria were allocated to the treatment group to receive 40 mg atorvastatin orally once daily for two weeks (n=26) or the placebo group (n=26). Patients' symptoms and laboratory investigations were assessed at baseline and during the follow-up period. We also evaluated the duration of hospitalization and supplemental oxygen therapy as endpoints. RESULTS: After 14-day of follow-up, the oxygen saturation (SaO2) was significantly higher, and the serum high sensitivity C-reactive protein (hs-CRP) level was lower in the treatment group compared to the placebo group. Moreover, at the end of the followup in the treatment group, the lymphocyte count was higher, and the duration of symptom resolution was shorter but not significant. Additionally, in the treatment group, the length of supplemental oxygen therapy and hospitalization duration were meaningfully shorter. Our results revealed that the mortality rate was almost twice higher in the placebo group compared to the treatment group, without any significant adverse drug reaction. CONCLUSION: Atorvastatin significantly reduces supplemental oxygen need, hospitalization duration, and serum hs-CRP level in mild to moderate hospitalized COVID-19 patients.

Personality traits of patients with multiple sclerosis and their correlation with anxiety and depression levels: A cross-sectional case-control study.

OBJECTIVE: Multiple sclerosis is a chronic demyelinating disease of the central nervous system that can cause severe disability and impair the quality of life (QoL). METHODS: In the current cross-sectional, case-control study, we investigated personality traits, anxiety and depression levels, in 101 patients in the case group and 202 individuals as a control group. The personality traits of the participants were collected via the Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI) questionnaire. We evaluated the level of anxiety and depression based on the Hospital Anxiety and Depression Scale questionnaire. RESULTS: Our study showed in patients with disease duration above 1 year, the rates of agreement (29.78), anxiety (8.83), and depression level (6.39) were significantly higher than the control group (27.19, 6.47, and 4.97, respectively). Although patients with disease duration below 1 year showed a higher level of agreement and conscientiousness (29.65 and 34.35, respectively) than controls (26.6 and 30.86, respectively). The level of anxiety and depression in patients with a disability index above 4.5 was significantly higher than patients with a disability index below 1. Patients with a disability index below 1 showed a higher rate of extraversion and agreement and conscientiousness (31.47, 31.53, and 35.07, respectively) than controls (25.5, 26.23, and 3033, respectively). In addition, patients with a disability index above 4.5 showed a higher level of agreement (35.64), conscientiousness (35.5), anxiety (9.64), and depression (7.5) than controls (25.96, 30.71, 6.96, and 4.71, respectively). CONCLUSIONS: In conclusion, anxiety and depression levels were much higher among MS patients compared with controls and the severity of these conditions correlate with the score of the disability index. Therefore, a complete comprehension of these conditions by the neurologist could be vital in improving patients' QoL and increasing compliance and adherence to pharmacological therapy.

Development of curcumin-loaded Prunus armeniaca gum nanoparticles: Synthesis, characterization, control release behavior, and evaluation of anticancer and antimicrobial properties.

The present work was conducted to develop a new polysaccharide-based encapsulation system via electrostatic interactions between Prunus armeniaca gum exudates (PAGE) and Ca2+ ions to enhance the biological activity and bioavailability of curcumin. The effects of different levels of pH (6, 7, and 8) and ion concentrations (1, 3, and 5) on the particle diameter and surface charge of the samples were examined. The encapsulation efficiency in the PAGE-based nanoparticles was realized to be 86.1%, indicating the encapsulation technique applied in this study was effective to entrap most of the curcumin within the PAGE matrix. The nanoparticles showed a smooth surface with spherical shape. Fourier transform infrared spectroscopy (FT-IR) and X-ray diffraction (X-ray) studies confirmed the formation of polyelectrolyte complexation. The cumulative release of curcumin in simulated gastrointestinal tract was less than 75%, revealing a gradual release trend. Both pure curcumin and curcumin-loaded nanoparticles were toxic to the cancer cell lines.

pH-sensitive soluble soybean polysaccharide/SiO2 incorporated with curcumin for intelligent packaging applications.

In the present work, the effect of various concentrations of SiO2 nanoparticles (5, 10, and 15%) on physicochemical and antimicrobial properties of soluble soybean polysaccharide (SSPS)-based film was investigated. Then, the migration of SiO2 nanoparticles to ethanol as a food simulant was evaluated. Subsequently, curcumin was added to the nanocomposite formulation to sense the pH changes. Finally, the cytotoxicity of the developed packaging system was investigated. With increasing nanoparticle concentration, the film thickness, water solubility, and water vapor permeability decreased and mechanical performance of the films improved. SSPS/SiO2 nanocomposite did not show antibacterial activity. SEM analysis showed that SiO2 nanoparticles are uniformly distributed in the SSPS matrix; however, some outstanding spots can be observed in the matrix. A very homogeneous surface was observed for neat SSPS film with R a and R q values of 3.48 and 4.26, respectively. With the incorporation of SiO2 (15%) into SSPS film, R a and R q values increased to 5.67 and 5.98, respectively. Small amount of SiO2 nanoparticles was released in food simulant. The nanocomposite incorporated with curcumin showed good physical properties and antibacterial activity. A strong positive correlation was observed between TVBN content of shrimp and a* values of the films during storage time (Pearson's correlation = 0.985).

Antioxidant, antimicrobial, and cytotoxic activities of extracts from the seed and pulp of Jujube (Ziziphus jujuba) grown in Iran.

The aim of the present study was to investigate the biological activities of the ultrasound-assisted extracts obtained from pulp and seed of jujube (Ziziphus jujuba) fruits. To reach this purpose, total phenolic content (TPC), total flavonoid content (TFC), total pro-anthocyanin, DPPH radical scavenging activity, rancimat test, as well as antimicrobial activity and cytotoxicity test of both jujube pulp and seed extracts were evaluated. Total phenolic content (TPC), total flavonoid content (TFC), and total pro-anthocyanin in pulp extract were higher than those obtained from seed extract. In addition, DPPH radical scavenging activity of pulp extract (IC50 = 53.97 µg/ml) was higher than that of seed extract (IC50 = 88.68 µg/ml). Furthermore, the highest antimicrobial activity was observed against Escherichia coli and Staphylococcus aureus (MIC = 20 mg/ml) for both seed and pulp extracts. In vitro cytotoxicity evaluation on seven cell lines revealed that pulp and seed extracts of jujube had no cytotoxic activity. The present results suggested the promising antioxidant properties of jujube, which can be used in the fabrication of functional bioactive ingredients for different purposes.

Prunus armeniaca gum exudates: An overview on purification, structure, physicochemical properties, and applications.

Prunus armeniaca gum exudate (PAGE) is obtained from the trunk branches of apricot trees. PAGE is a high-molecular-weight polysaccharide with arabinogalactan structure. The physicochemical and rheological characteristics of this gum have been investigated in various researches. PAGE offers a good potential for use as an emulsifying, binding, and stabilizing agent in food and pharmaceutical industries. It also can be used as an organic additive in tissue culture media, synthesizing of metallic nanoparticles, binding potential in tablets, antioxidant agent, and corrosion inhibitor. For desirable emulsifying, stabilizing, shelf life-enhancing properties, and antioxidant activity of PAGE, it can be used as additive in many foods. We present here a comprehensive review on the existing literatures on characterization of this source of polysaccharide to explore its potential applications in various systems.

Fenugreek seed gum: Biological properties, chemical modifications, and structural analysis- A review.

Fenugreek is a leguminous plant belongs to the family Fabaceae, which is extensively cultivated as a semiarid crop in Northern Africa, the Mediterranean, India, and Canada. In the present review paper, first we summarized the extraction, purification, chemical composition, molecular structure, and rheological behavior of the mucilages isolated from Fenugreek seeds (FSG), and then their functional properties presented to elucidate the potential application of this traditional source of hydrocolloids in food, pharmaceutical, and other industries. To date, there is no technique that can successfully remove the attached protein from FSG. From a structural point of view, galactose and mannose are the most abundant polysaccharide in FSG composition, suggesting a galactomannan-like structure. FSG is the most soluble of the seed gums. FSG solutions at various temperatures and concentrations showed a time-dependent shear thinning behavior. Furthermore, these hydrocolloids can be employed for the fabrication of eco-friendly packaging systems. Antioxidant capacity and anti-fungi activity of FSG has been proved in different studies. In conclusion, industrial applications of FSG are possible due to its strong thickening properties. Additionally, FSG has an excellent emulsification capacity, which enables its application in the food, cosmetic and/or pharmaceutical industries.

LC-ESI/LTQOrbitrap/MS/MS and GC-MS profiling of Stachys parviflora L. and evaluation of its biological activities.

The use of some Stachys genus as herbal remedies is known and the aerial parts have a pharmaceutical interest, being used in Anatolia and Iran as wild tea. In this study, chemical composition, antimicrobial, antioxidant, and antiproliferative activities of the methanolic extract and essential oil (EO) of Stachys parviflora L. (S. parviflora) were evaluated. Qualitative analysis of metabolites of S. parviflora methanolic extract was studied using liquid chromatography coupled to high resolution mass spectrometry (LC-ESI/LTQOrbitrap/MS), evidencing the presence of phenolic acids and flavonoids derivatives. The EO was analyzed using gas chromatography coupled to mass spectrometry (GC/MS). Eighty-seven compounds were characterized in the EO of S. parviflora, of which α-terpenyl acetate (23.6%), ß-caryophyllene (16.8%), bicyclogermacrene (9.3%), spathulenol (4.9%) and α-pinene (4.2%) were found to be the major components. The highest antimicrobial effect of EO was found to S. aureus and B. cereus (MIC = 0.01 µg/ml), while the highest activity of extract was against B. cereus (MIC = 125 µg/ml). The methanolic extract exhibited strong antioxidant activity in DPPH (IC50 = 76.87 µg/ml) and ß-carotene/linoleic acid assay (BCB, IC50 = 188.47 µg/ml) methods. Furthermore, in vitro cytotoxicity evaluation against three cell lines namely human ovarian carcinoma (A2780), human colon carcinoma (HCT), and mouse melanoma cell line (B16F10), showed an anti-proliferative activity of the EO ranging from IC50 value 30.95 µg/ml to 16.55 µg/ml. The results from this study have demonstrated the promising cytotoxic, antibacterial, and antifungal properties of S. parviflora, which could have wide potential applications in food and pharmaceutical industries.

Environment-friendly green composites based on soluble soybean polysaccharide: A review.

The objective of the present review was to acquaint the readers with recent advances in soluble soy bean polysaccharide (SSPS)-based films. An efficient extraction method containing refining, pasteurizing and spray-drying is commonly used to extract SSPS. SSPS is a high molecular weight polysaccharide with a pectin-like structure. The predominant monosaccharide components are arabinose, galactose and galacturonic acid. Additionally, a trace amount of other monosaccharides such as glucose, fucose, rhamnose, and xylose are also present. SSPS allows us to make water-soluble, colorless, transparent, and edible films due to its high adhesive strength. The evaluation of recently published data on the development of SSPS films has demonstrated that nanoparticles can be used to improve the physicochemical characteristics of SSPS films. These nanoparticles not only reinforce the mechanical, thermal and physical properties of SSPS films, but also improve their antibacterial, anti-mold and anti-yeast activities. Hence, reinforcement of SSPS with nanoparticles is expected to open new approaches for revealing their applications in food packaging.

An update on physicochemical and functional properties of newly seed gums.

Natural gums are complex polysaccharides polymers commonly used as plasticizing, emulsifying, stabilizing, thickening, gelling, binding and coating agents, fat replacer, flavor encapsulator, and carrier. Plant seed gums, which are used in biomedical and biopharmaceutical fields, have attracted the attention of researchers due to their unique characteristics. The functional characteristics and potential application of natural polymers considerably depend on their structural and physicochemical properties. The aims of the present review were, therefore, first, summarize the structural and physicochemical properties of newly seed gums and then investigation of the relation between these properties with their functional characteristics to explore their potential applications in food, pharmaceutical, paper, and other industries.

Characterization of a green nanocomposite prepared from soluble soy bean polysaccharide/Cloisite 30B and evaluation of its toxicity.

The present paper aims to elucidate the structural, thermal and mechanical properties of soybean polysaccharide (SSPS)/Cloisite 30B. Tensile strength of the nanocomposite films improved with incorporation of nanoparticles, whereas elongation at break decreased. Surface roughness of the samples increased with the addition of nanoclay. Neat SSPS film and SSPS-1% Cloisite 30B had a relatively smooth surface with no irregularities, while for the samples containing 3 and 7% Cloisite 30B, the surface was rough. DSC analysis demonstrated that following an increase in nanoparticles content, the melting temperature of the nanocomposite elevated, whereas, glass transition temperature decreased. The results of antibacterial activity indicated that Cloisite 30B could inhibit the growth of Salmonella typhi PTCC 1609, Staphylococcus epidermis PTCC 1114 (ATCC 12228) and Listeria monocytogenes PTCC 1165. SSPS-Cloisite 30B nanocomposite could not inhibit the growth of Aspergillus niger. The results demonstrated that the migration of nanoparticles might happen into deionized water as a food simulant, but they could not migrate into bread as a food model. Furthermore, it was found that Cloisite 30B nanoparticles had cytotoxicity effect, and thus, it is recommended that Cloisite 30B/SSPS nanocomposites be used only for the packaging of solids foods such as bread.

Soluble soybean polysaccharide/TiO2 bionanocomposite film for food application.

In the current study, a set of biodegradable soybean polysaccharide (SSPS) nanocomposites containing different ratios of TiO2 nanoparticles was characterized as new packaging system. X-ray diffraction (XRD) measurement showed that the crystalline structure of the TiO2 nanoparticles remained intact in the polysaccharide matrix and the surface of nanocomposites containing 1-3% TiO2 was observed morphologically uniform under scanning electron microscopy (SEM). Dynamic mechanical thermal analysis revealed that the magnitude of storage modulus was 3.62-fold higher in SPSS/TiO2 nanocomposites containing 7 wt.% of TiO2 than control SSPS indicating improvement in the physical properties of the film supposed to be utilized for food packaging. With respect to the concern over the safety of these nanocomposites, inductively coupled plasma-optical emission spectroscopy (ICP-OES) showed that no TiO2 was detected in bread samples covered by SSPS/TiO2 film and stored for 6 months. Similarly, the nanocomposite films only released a minuscule amount (21.05 ±â€¯0.054 ppm) of TiO2 in water. TiO2 nanoparticles were found in the plasma membrane of epithelial cell line after long-term exposure (10-day) of these cells to large amounts of the free nanoparticles. SSPS/TiO2 nanocomposites showed excellent antimicrobial activity against Staphylococcus aureus PTCC 1431 (ATCC 25923), while neither anti-cancerous nor pro-cancerous activity was observed for these nanocomposites denoting their neutrality with respect to cancer suppression or progression in gastrointestinal tract. In conclusion, SSPS/TiO2 nanocomposites could be a promising packaging system for food industries' objective regarding their physical characteristics, low rate of Ti transition, and low health risk.

Characterization of soluble soybean (SSPS) polysaccharide and development of eco-friendly SSPS/TiO2 nanoparticle bionanocomposites.

This research aims to characterization of soluble soybean polysaccharide (SSPS) and development of a biodegradable SSPS nanocomposites prepared using various concentrations of TiO2 nanoparticles. 13C NMR suggested that backbone of SSPS is rhamnogalacturonan [1→4)-α-GalAp-(1/2)-α Rhap(1→]. Weight average molecular weight, number average molecular weight (Mn) and polydispersity index (PDI) of SSPS were found to be 2.54×106g/mol, 5.54×106g/mol, and 4.5, respectively. The intrinsic viscosity of SSPS (0.33) was lower than most of hydrocolloids. With increasing TiO2 concentration, the water solubility, moisture content and water-vapor permeability (WVP) of SSPS-based nanocomposite films decreased. TiO2 addition led to an increase in the melting temperature to a maximum of 132°C for the SSPS nanocomposite with 5wt% TiO2. With increasing TiO2 concentrations from 5 to 15wt%, the melting temperature declined from 24 to 19°C. There were no significant agglomerates when the TiO2 concentrations were increased to 5wt%; however, when the concentration reached 15wt%, agglomerations were observed. With addition of TiO2 nanoparticles, tensile strength increased but elongation at break decreased. SSPS-based nanocomposite films demonstrated a promising range of antimicrobial activity. The current research clearly introduces a new antimicrobial composite which is potentially useful to prevent and treat infections.

Eco-friendly soluble soybean polysaccharide/nanoclay Na+ bionanocomposite: Properties and characterization.

The impact of montmorillonite (MMT) as a nanofiller at different concentrations (5, 10, 15wt.%) on the physicochemical and functional properties of nanocomposite film based on soluble soybean polysaccharide (SSPS) was investigated. The results showed that an increase in MMT concentration was accompanied by a decrease in water solubility, thickness, and elongation at break. Furthermore, tensile strength increased when MMT concentration was increased to 10wt.%. Atomic force and scanning electron micrographs showed a significant agglomeration at MMT 15wt.%. With added MMT, the level of whiteness, greenness, and yellowness of SSPS film increased (P<0.05). Dynamic mechanical thermal analysis indicated that the storage modulus of nanocomposites increased when the MMT was increased to 10wt.%. Furthermore, Fourier transform infrared spectrophotometry demonstrated that no considerable changes occurred in the functional groups of the SSPS when MMT was added. Antimicrobial tests revealed that antibacterial and anti-mold activities were unlikely from reinforced nanocomposites.

Development of new active packaging film made from a soluble soybean polysaccharide incorporating ZnO nanoparticles.

This study aimed to develop a soluble soybean polysaccharide (SSPS) nanocomposite incorporating ZnO nanoparticles. The nanocomposites were prepared using the solvent-casting method. SEM, AFM, DSC and X-ray diffraction methods were applied to characterize the resulting films. Furthermore, the antibacterial and anti-mold activities of SSPS/ZN films were assessed against the selected microorganisms. The results indicated that incorporating ZNs into the SSPS film affected the tensile strength and elongation at break significantly. In addition, the antibacterial, antifungal and yeasticidal activities of ZnO/SSPS films have been approved. XRD results showed a crystal plane of hexagonal ZN, while SEM showed that there was not a good affinity between ZN and SSPS. Mono-dispersed particles with clearly spherical morphology and with no voids on the surface were observed using AFM. Fluctuation in Tg and Tm resulted from incorporating ZN. In summary, the potential of ZNs as a functional filler in SSPS film has been demonstrated.

Synbiotic yogurt-ice cream produced via incorporation of microencapsulated lactobacillus acidophilus (la-5) and fructooligosaccharide.

Yogurt-ice cream is a nutritious product with a refreshing taste and durability profoundly longer than that of yogurt. The probiotic Lactobacillus acidophilus (La-5) cells either in free or encapsulated form were incorporated into yog-ice cream and their survivability were studied. Fructooligosaccharide (FOS) as a prebiotic compound at three levels (0, 4 & 8 % w/w) was added to yogurt-ice cream mix and its effects on some chemical properties, overrun and firmness of product were evaluated. The higher the incorporated FOS concentration, the lower were the pH value and higher the total solid content of treatments. FOS incorporation (8 %) significantly increased the overrun of treatments and reduced their firmness. The viable counts of free probiotics decreased from ~9.55 to ~7.3 log cfu/g after 60 days of frozen storage while that of encapsulated cells merely decreased less than 1 log cycle. Encapsulation with alginate microbeads protected the probiotic cells against injuries in the freezing stage as well as, during frozen storage.

Development of new active packaging film made from a soluble soybean polysaccharide incorporated Zataria multiflora Boiss and Mentha pulegium essential oils.

An active edible film from soluble soybean polysaccharide (SSPS) incorporated with different concentrations of Zataria multiflora Boiss (ZEO) and Mentha pulegium (MEO) essential oils was developed, and the film's optical, wettability, thermal, total phenol and antioxidant characteristics were investigated, along with their antimicrobial effectiveness against Staphylococcus aureus, Bacillus cereus, Escherichia coli O157:H7, Pseudomonas aeruginosa and Salmonella typhimurium. The film's colour became darker and more yellowish and had a lower gloss as the levels of ZEO or MEO were increased. Antioxidant activity of the films was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), and ferric-reducing antioxidant power assays. DPPH was reduced in the range of 19.84-74.12% depending on the essential oil type and concentration. Film incorporated with 3% (v/v) ZEO showed the highest DPPH radical scavenging activity and ferric reducing antioxidant power (IC50=4188.60±21.73mg/l and EC50=8.86±0.09mg/ml, respectively), compared with the control and MEO added film. Films containing ZEO were more effective against the tested bacteria than those containing MEO. S. aureus was found to be the most sensitive bacterium to both ZEO or MEO, followed by B. cereus and E. coli. A highest inhibition zone of 387.05mm(2) was observed for S. aureus around the films incorporated with 3% (v/v) ZEO. The total inhibitory zone of 3% (v/v) MEO formulated films was 21.98 for S. typhimurium and 10.15mm(2) for P. aeruginosa. Differential scanning calorimetry (DSC) analysis revealed a single glass transition temperature (Tg) between 16 and 31°C. The contact angle increased up to 175% and 38% as 3% (v/v) of ZEO or MEO used: it clearly shows that films with ZEO were more hydrophobic than those with MEO. The results showed that these two essential oils could be incorporated into SSPS films for food packaging.
