Valorisation of olive pomace: phenolic prospecting and biological potential.

Phenolic compounds were extracted from biphasic olive pomace and their biological potential was characterised. Two different extracts were prepared, E1 (40% methanol) and E2 (80% methanol), both subjected to agitation (180 min) and 70 °C. LC-ESI-qTOF-MS was used for individual quantification of the extracted phenolic compounds. The antioxidant activity was determined using different methods, including nitric oxide, DPPH (2,2-diphenyl-1-picrylhydrazyl) and hydroxyl radical. The enzymes α-amylase and α-glucosidase were used to evaluate the antihyperglycemic potential and sulforhodamine B and MTT (tetrazolium salt) for antitumor activity. To evaluate the antimicrobial activity, minimum inhibitory concentration and minimum bactericidal concentration of the extracts, the disc diffusion technique was used. Among the phenolic compounds present, tyrosol was highlighted in both extracts, as well as the anti-hyperglycemic effects, antitumor action and antioxidant activity. The antimicrobial activity found in the extracts was considered moderate to weak.

Trends in research on cacti: the food of the future.

Cacti are a distinguished group of plants that stand out for their great nutritional values, diverse uses, and unique morphology, allowing them to grow and thrive under different conditions such as dry, xeric, and even low-temperature environments. The world is going through significant climate changes that are affecting the agriculture system. Therefore, sustainable and multifunctional crops, as many species of the Cactaceae family are, might be a good alternative in the near future. In this work, the uses of cacti in human food were analyzed through a scientific prospection from the point of view of their temporal and spatial distribution and potential uses. Brazil is the country with more publications related to the scope of this work, followed by Mexico. The presence of cacti in these countries can influence their interest in these species, which might reflect the results encountered in this study. The uses and ethnobotanical applications of cacti vary in different countries worldwide. Cactus is consumed fresh (in salads), in preparations (jams and sweets), and juices, being also present in traditional dishes in countries like Mexico. This study emphasizes cacti's importance in people's diets and ongoing world changes. Their ability to thrive even in hot environments with low water resources will lead to a greater focus on these species in the upcoming years. Furthermore, these plants have great flavor and contain several beneficial chemical compounds with desirable nutritional and health properties. Therefore, knowledge dissemination combined with technological innovations will allow greater use of these multifunctional species for human consumption. © 2024 Society of Chemical Industry.

Chia mucilage carrier systems: A review of emulsion, encapsulation, and coating and film strategies.

The use of carrier systems for the protection and delivery of bioactive compounds in the agri-food industry is an area of opportunity that requires the design of new systems and sources of materials for their structure. Chia seeds (Salvia hispanica L.) produce mucilage with functional qualities that allow their application in diverse areas of the food industry. These qualities have been used to form very stable carrier systems, such as capsules, emulsions, coatings, and films that can protect and prolong the functionalities of loaded compounds (e.g., antimicrobial and antioxidant capabilities). This paper presents a review of chia mucilage-based carrier systems and their applications in food products (micro-and nanoparticles, emulsions, coatings, and films for food packaging), as well as the current technological prospects of these systems. The use of chia mucilage in coatings and films shows a high potential for use in biodegradable, edible, and organic packaging. Although many studies have been conducted on chia mucilage encapsulation systems, there is still a gap in the application of capsules and particles in food.

Biosorption of methylene blue by residue from Lentinus crinitus mushroom cultivation.

Conventional textile effluent treatments cannot remove methylene blue, a mutagenic azo dye, and an endocrine disruptor, that remains in the drinking water after conventional water treatment. However, the spent substrate from Lentinus crinitus mushroom cultivation, a waste, could be an attractive alternative to remove persistent azo dyes in water. The objective of this study was to assess the methylene blue biosorption by spent substrate from L. crinitus mushroom cultivation. The spent substrate obtained after mushroom cultivation had been characterized by the point of zero charge, functional groups, thermogravimetric analysis, Fourier transform infrared spectroscopy, and scanning electron microscopy. Moreover, the spent substrate biosorption capacity was determined in function of pH, time, and temperature. The spent substrate had a point of zero charge value of 4.3 and biosorbed 99% of methylene blue in pH from 3 to 9, with the highest biosorption in the kinetic assay of 15.92 mg g- 1, and in the isothermal assay of 120.31 mg g- 1. Biosorption reached equilibrium at 40 min after mixing and best fitted the pseudo-second-order model. Freundlich model best fitted the isothermal parameters and each 100 g spent substrate biosorbed 12 g dye in an aqueous solution. The spent substrate of L. crinitus cultivation is an effective biosorbent of methylene blue and an alternative to removing this dye from water, adding value to the mushroom production chain, and supporting the circular economy.

Pachira aquatica (Malvaceae): An unconventional food plant with food, technological, and nutritional potential to be explored.

Pachira aquatica (Malvaceae) is an unconventional food plant (UFP) native to Mexico and found all over Brazil, where it is commonly known as monguba. It has an arboreal shape, exotic flowers, and a fruit similar to cocoa with several seeds. Although its main application is in urban ornamentation and folk medicine, monguba's fruit has a great potential for use in the food, pharmacology, cosmetic, and bioenergy industry, mainly due to its oil's characteristics. This review aims to compile the nutritional composition, bioactive and antioxidant activities, and technological and nutritional potential of monguba's seed, leaf, and fruit pericarp. It reviews studies of different databases between January 2018 and October 2021. Monguba seeds are rich in lipids, proteins, and minerals; the bark is rich in fiber; and all parts of the fruit have bioactive compounds. Discussing the use of UFP is a way of finding new alternative food sources, usually discarded, offering products with high nutritional value allied to technological and consumption potential, such as the monguba fruit.

Nutritional and technological potential of cactus fruits for insertion in human food.

The Cactaceae family can be easily found in the arid and semiarid regions, with a significant waste of its potentials, being generally used as forage. Considering that much research have shown antioxidant properties and bioactive compounds in cacti species, this review aimed to review and discuss recent advances in physicochemical composition, bioactive compounds, and antioxidant activity of Cereus jamacaru, Melocactus zehntneri, Pilosocereus gounellei, Opuntia ficus-indica and Pilosocereus pachycladus fruits to investigate their food technology potential for new products development. These fruits have important amounts of micro, macronutrients, and bioactive compounds, which allow them a wide variety of uses, fresh or processed, and for industrial purposes for the production and extraction of compounds of interest (dyes, antioxidants, antimicrobials, etc.) as demonstrated in the literature. Furthermore, exploring the diversity of uses of these fruits can provide significant benefits from an economic, technological, social, environment, food, and nutritional security point of view.

Rosaceae rubus rosifolius smith: nutritional, bioactive and antioxidant potential of unconventional fruit.

Rubus is an economically important fruit, highly valued for its taste and medicinal properties. Itis estimated that there are between 400 and 700 species, but many of them are still unknown to the general population. There is a little information in the literature about the physicochemical and bioactive composition, as well as the antioxidant activity of these fruit, which is why this research was carried out. The fruits showed lipids (7.42%), ash (0.27%), dietary protein (11.54%), fiber (23.72%), carbohydrates (59.18%), low acidity, and good °Brix. Regarding bioactive compounds, good concentrations of phenolic compounds (289.4 (mg. g-1 EAG), flavonoids (155 mg100g-1), anthocyanins (120.11 mg cyanidin-3-glucoside 100 g-1), and phytoene (517.3 mg100g-1) were found. The wild strawberry showed a good antioxidant capacity, which was confirmed by different analytical methods. Because of the results of this research, it is concluded that this fruit has nutritional and phytochemical potential that should be included in the human diet, and its consumption should therefore be encouraged.

A comparison of front-line oral anticoagulants for the treatment of non-valvular atrial fibrillation: effectiveness and safety of direct oral anticoagulants in the FANTASIIA registry.

INTRODUCTION: For a long time, vitamin K antagonists (VKA) were the only oral anticoagulation therapy available to reduce adverse events in atrial fibrillation (AF) patients. Direct-acting oral anticoagulants (DOAC) are at least as effective and safe as VKA with few drug interactions, rapid onset, and short half-life. Four DOACs, dabigatran, apixaban, rivaroxaban, and edoxaban, have demonstrated efficacy and safety for treatment in AF patients. AREAS COVERED: The purpose of this review article is to analyze the current evidence in clinical trials and in real-world populations and performed a new analysis with the estimated effect of those DOACs over the VKA population from the FANTASIIA registry. EXPERT OPINION: In the absence of randomized, controlled head-to-head comparisons between DOACs, high-quality observational data can provide useful information on the comparative effectiveness of DOACs. Current clinical guidelines recommend the management of oral anticoagulation in AF patients with DOACs over VKA for stroke prevention; however, many guidelines generally do not suggest a specific DOAC choice in clinical practice. The revised evidence in this manuscript and our real experience reflects that apixaban and dabigatran show the best efficacy and safety profile.

Exploring alternative protein sources: Evidence from patents and articles focusing on food markets.

This review considers alternative protein sources through the analysis of food science literature and patents. Data collection was performed from scientific literature and patent documents using the Scopus and National Institute of Industrial Property databases, with a term combination "alternative protein source" and "source* AND protein* AND alternative*". A total of 945 documents were analyzed. The scientific prospection showed that agricultural and biological science was the main application area. The food industry area had the highest number of filed patents. The annual evaluation of published documents demonstrated that this area had been investigated since the 1970s, and the number of articles was twice than that of filled patents. Although protein products are available for sale, animal and vegetable sources replace conventional protein products. Presently, alternative protein sources are already a worldwide trend in the food industry, enabling the development of new products to facilitate their insertion into the consumer market.

Long-term cryopreservation of Lentinus crinitus strains by wheat grain technique.

Lentinus crinitus (Basidiomycota: Polyporales) is a saprophytic fungus with biotechnological importance described more than 20 years ago. However, there are few studies on the long-term preservation of this basidiomycete. Cryopreservation is a long-term storage technique that reduces the metabolic activity of microorganisms, but its success depends on the adjustment of the freezing process, the cryoprotectants, and the protective substrates for each species. This study aimed to assess the mycelial viability and genetic stability of L. crinitus strains cryopreserved at -86 °C for two years by the wheat grain technique using different cryoprotectants and freezing methods. Three strains of L. crinitus (U9-1, U13-5, and U15-12) were subjected to different concentrations and types of cryoprotectants (dimethyl sulfoxide, glycerol, glucose, and sucrose), freezing methods such as immediate freezing from 25 to -86 °C and progressing freezing from 25 to -86 °C in a freezing container with isopropyl alcohol to control the rate of cell freezing at -1 °C min-1, protective substrate (wheat grain and 2% malt extract agar), and cryopreservation period (1, 6, 12, and 24 months). After thawing, samples were evaluated for mycelial viability, time to mycelial recovery, mycelial stability, and genetic stability of the fungus. All techniques achieved effective cryopreservation at -86 °C, mainly with the wheat grain technique. All cryoprotectants (3.5% glycerol, 1.5% dimethyl sulfoxide, 25% sucrose, and 5% glucose), freezing methods (immediate and gradual), and protective substrate (wheat grain and malt extract agar) were effective for cryopreservation of the three L.crinitus strains in an ultra-low temperature freezer for two years. Mycelial viability, mycelial stability, and genetic stability of the fungus were not affected after two-year cryopreservation, evidencing the robustness of the long-term cryopreservation technique and the fungus.

Impact of Integrated Care Management on Clinical Outcomes in Atrial Fibrillation Patients: A Report From the FANTASIIA Registry.

Background: An integrated and holistic approach is increasingly advocated in patients with atrial fibrillation (AF), based on the "Atrial fibrillation Better Care (ABC) pathway: A, Avoid stroke with anticoagulation; B, better symptom management; C, cardiovascular and comorbidity risk management." The aim of this study was to examine the prevalence of adherence to each component of the ABC pathway and to analyze its impact on long-term prognosis in the "real-world" cohort of AF patients from the FANTASIIA registry. Methods: This prospective study included consecutive AF outpatients anticoagulated with direct oral anticoagulants (DOAC) or vitamin K antagonists (VKA) from June 2013 to October 2014. From the ABC pathway, adherence to the "A criterion" was defined by a time in the therapeutic range (TTR) ≥ 70% or correct dose with DOAC; "B criterion" adherence was defined by a European Heart Rhythm Association (EHRA) Symptom Scale I-II; and "C criterion" adherence was defined as optimized risk factors and comorbidity management. Baseline features and embolic events, severe bleeding, and all-cause and cardiovascular mortality rates up to 3 years of follow-up were analyzed, and a Cox multivariate analysis was performed to investigate the role of each component of the ABC pathway in predicting major events. Results: A total of 1,955 AF patients (age: 74.4 ± 9.4 years; 43.2% female patients) were included in this study: adherence to A criterion was observed in 920 (47.1%) patients; adherence to B criterion was observed in 1,791 (91.6%) patients; and adherence to C criterion was observed in 682 (34.8%) patients. Only 394 (20.2%) of the whole population had good control of AF according to the ABC pathway. After a median follow-up of 1,078 days (IQR: 766-1,113), adherence to A criterion was independently associated with reduced cardiovascular mortality [HR: 0.67, 95%CI (0.45-0.99); p = 0.048] compared with non-adherence. Adherence to the B criterion was independently associated with reduced stroke [HR: 0.28, 95%CI (0.14-0.59); p < 0.001], all-cause mortality [HR: 0.49, 95%CI (0.35-0.69); p < 0.001], cardiovascular mortality [HR: 0.39, 95%CI (0.25-0.62); p < 0.001], and major adverse cardiovascular events (MACE) [HR: 0.41, 95%CI (0.28-0.62); p < 0.001] compared with non-adherence. AF patients with C criterion adherence had a significantly lower risk of myocardial infarction [HR: 0.31, 95%CI (0.15-0.66); p < 0.001]. Fully adherent ABC patients had a significant reduction in MACE [HR: 0.64, 95%CI (0.42-0.99); p = 0.042]. Conclusion: In real-world anticoagulated AF patients from FANTASIIA registry, we observed a lack of adherence to integrated care management of AF following the ABC pathway. AF managed according to the ABC pathway was associated with a significant reduction in adverse outcomes during long follow-up, suggesting the benefit of a holistic and integrated approach to AF management.

A Patent Data Analysis in Nanotechnology Applied to Essential Oils.

BACKGROUND: Essential oils (EOs) are natural substances that serve as sources of bioactive compounds with antioxidant and antimicrobial properties. OBJECTIVE: This objective is to understand intellectual property related to patent documents on EOs and nanotechnology. METHODS: The nanotechnology growth curve applied to EOs demonstrated that the period from 2015 to 2017 was the most prominent, with a peak in 2016. China is the dominant country, mainly through research developed in the academic area. RESULTS: The food industry area had the highest number of patents filed, highlighting the preservation line. Ginger essential oil, chitosan and Tween 80 were preferentially used as a core, wall material, and emulsifier, respectively. In the market, the use of EOs is more associated with the pharmaceutical/ cosmetics industry. In addition, the food industry market bets more on products based on hemp oil nanocapsules. CONCLUSION: EO nanotechnology is promising for the development of sustainable food systems. However, this nanotechnology in Brazil has not yet advanced enough in the food industry, although there are government incentives that may change this paradigm in the future. The profile of the patent documents and the products in the market differ between the application and the types of oils. In addition, there is a gap between the volume of patent documents investigated and the transfer of technology to the commercial sector, but this constitution could be better explored, given the properties of EOs.

Prospective Study on Microencapsulation of Oils and Its Application in Foodstuffs.

BACKGROUND: Edible oils have gained the interest of several industrial sectors for the different health benefits they offer, such as the supply of bioactive compounds and essential fatty acids. Microencapsulation is one of the techniques that has been adopted by industries to minimize the degradation of oils, facilitating their processing. OBJECTIVE: To evaluate the intellectual property related to patent documents referring to microencapsulated oils used in foods. METHODS: This prospective study investigated the dynamics of patents filed in the Espacenet and National Institute of Industrial Property (INPI) databases, and it mapped technological developments in microencapsulation in comparison with scientific literature. RESULTS: The years 2015 and 2018 showed the greatest growth in the number of patents filed in the Espacenet and INPI databases, respectively, with China leading the domains of origin, inventors, and owners of microencapsulation technology. The largest number of applications of microcapsules were observed in the food industry, and the foods containing microencapsulated oils were powdered seasonings, dairy products, rice flour, nutritional formulae, pasta, nutritional supplements, and bread. The increase in oxidative stabilities of oils was the most cited objective to microencapsulate oils. Spray drying was the most widely used microencapsulation technique, and maltodextrin, gum arabic, and modified starch were the most widely used wall materials. CONCLUSION: Microencapsulation of oils has been expanding over the years and increasing the possibilities of the use of microcapsules, but further investments and development of policies and incentive programs to boost this technology need to be made in less developed countries. For future perspectives, the microencapsulation technique is already a worldwide trend in the food industry, enabling the development of new products to facilitate their insertion in the consumer market.

Novel bioactive nanoparticles from crude palm oil and its fractions as foodstuff ingredients.

Novel bioactive nanoparticles derived from crude palm oil (CPO), palm olein, and palm stearin for use in foodstuff products were produced, and their physicochemical characteristics and stability were evaluated. The nanoparticles were prepared by homogenization, using biodegradable casein or gum arabic as an encapsulating material. The encapsulation efficiency (EE), morphology, long-term stability, particle size, polydispersity index, zeta potential, pH, apparent viscosity, color parameters, total carotenoids, and antioxidant activity were determined. All nanoparticles methods produced spherical nanoparticles with EE higher than 85%. Highly homogeneous small particles (<300 nm) showing a tendency toward a yellow color were observed after 60 days of storage at 4 °C. The nanoparticles showed a carotenoid retention index higher than 40% and an antioxidant activity higher than 1,000 µM Trolox/g oil. The bioactive nanoparticles retained the carotenoids and are proposed as a green innovative product to replace synthetic colorants and antioxidants in foodstuffs.

Red Tomato Products as an Alternative to Reduce Synthetic Dyes in the Food Industry: A Review.

Most dyes used in the food industry are synthetic and can be a health hazard. Red tomato may serve as a natural alternative dye to replace synthetic colorants. This study aimed to review the literature on the addition of red tomato products (powder tomato, paste, freeze-dried, tomato peel powder, tomato pomace) to reduce the usage of synthetic dyes in the food industry. Red tomato products have been used as coloring in pasta, bologna, sausages, cookies, crackers, macaroons, hamburgers, breads, muffins, cheeses, and nuggets. The trans-cis isomerization of lycopene by oxidative processes directly affects the color of the pigment. The lycopene contained in tomato has antioxidant activity and could reduce or eliminate other oxidants and/or synthetic preservatives in food. Moreover, tomatoes in foods have high sensory scores, nutritional appeal, and marketing potential. However, its use as a food colorant has been not extensively explored. Therefore, further studies are still required, especially on the stability of carotenoids in tomatoes used in processed foods.

Study of the thermal stability of γ-oryzanol present in rice bran oil over time.

BACKGROUND: Rice bran oil is unique among edible oils owing to its rich source of commercially and nutritionally important phytochemicals, such as oryzanol. γ-Oryzanol performs an important role in the stability of rice bran oil. The crude rice bran oil obtained by solvent extraction is subjected to either chemical or physical refining to meet the specifications of edible-grade vegetable oil. These refining processes can cause the compounds present in rice bran oil to degrade. The aim of this study was to evaluate the stability of γ-oryzanol present in chemically and physically refined rice bran oils, when submitted to temperatures of 100, 140, and 180 °C for a period of 1368 h. RESULTS: The chemically refined rice bran oil presented a lower γ-oryzanol content than the physically refined rice bran oil at all heating temperatures. The losses of γ-oryzanol at 100 °C, 140 °C, and 180 °C at the end of the heating periods for the chemically refined oil were 53.47%, 58.48%, and 97.05% respectively, and for the physically refined oil the losses were 38.11%, 53.58%, and 91.11% respectively. CONCLUSION: Based on the results of the time to reduce the oryzanol concentration by 50% and 100%, it is observed that the oil of rice meal refined physically presents greater stability, in the different temperatures studied and over time, than the oil of rice meal refined chemically. Thus, for situations where the oil needs to be subjected to prolonged heating, a temperature of 100 °C is indicated. In this condition, the physically refined oil is better for maintaining a higher concentration of γ-oryzanol. © 2021 Society of Chemical Industry.

Metabolic profile of olive leaves of different cultivars and collection times.

Due to the appreciable amounts of bioactive compounds in olive leaves and the effect of abiotic stresses on their synthesis, this study evaluated the metabolic profile of leaves of olive cultivars (Arbequina, Manzanilla and Picual) collected in four periods of the year (autumn, winter, spring and summer). The determination of the profile of bioactive compounds (phenolic compounds, flavonoids, tannins, carotenoids and chlorophylls) by spectrophotometry and the individual compounds by liquid chromatography coupled to mass spectrum, as well as antioxidant potential tests were performed. As results it was possible to observe that the leaves of the cultivar Manzanilla presented the highest levels of phenolic compounds and that the leaves collected in the summer presented a number of compounds much more relevant than the others. Thus, it was possible to conclude that the cultivar and the collection season significantly affect the bioactive content and the antioxidant potential of olive leaves.

Impact of donor-recipient age on cardiac transplant survival. Subanalysis of the Spanish Heart Transplant Registry.

INTRODUCTION AND OBJECTIVES: The age of heart transplant recipients and donors is progressively increasing. It is likely that not all donor-recipient age combinations have the same impact on mortality. The objective of this work was to compare survival in transplant recipients according to donor-recipient age combinations. METHODS: We performed a retrospective analysis of transplants performed between 1 January 1993 and 31 December 2017 in the Spanish Heart Transplant Registry. Pediatric transplants, retransplants and combined transplants were excluded (6505 transplants included). Four groups were considered: a) donor <50 years for recipient <65 years; b) donor <50 years for recipient ≥ 65 years; c) donor ≥ 50 years for recipient ≥ 65 years, and d) donor ≥ 50 years for recipient <65 years. RESULTS: The most frequent group was young donor for young recipient (73%). There were differences in the median survival between the groups (P <.001): a) younger-younger: 12.1 years, 95%CI, 11.5-12.6; b) younger-older: 9.1 years, 95%CI, 8.0-10.5; c) older-older: 7.5 years, 95%CI, 2.8-11.0; d) older-younger: 10.5 years, 95%CI, 9.6-12.1. On multivariate analysis, independent predictors of mortality were the age of the donor and the recipient (0.008 and 0.001, respectively). The worst combinations were older-older vs younger-younger (HR, 1.57; 95%CI, 1.22-2.01; P <.001) and younger-older vs younger-younger (HR, 1.33; 95%CI, 1.12-1.58; P=.001). CONCLUSIONS: Age (of the donor and recipient) is a relevant prognostic factor in heart transplant. The donor-recipient age combination has prognostic implications that should be identified when accepting an organ for transplant.

Relationship of adverse events to quality of anticoagulation control in atrial fibrillation patients with diabetes: real-world data from the FANTASIIA Registry.

BACKGROUND: Atrial fibrillation (AF) patients with diabetes (DM) have high risk of cardiovascular events. PURPOSE: To compare clinical characteristics, adverse outcomes and quality of anticoagulation in AF patients regarding DM status. METHODS: AF patients from FANTASIIA registry were included. Baseline characteristics and comorbidities were recorded. After 2-years follow-up, the association between adverse events and DM was evaluated. RESULTS: 1956 patients (mean age 73.8 ± 9.5 years, 56% male) were analyzed; 574 (29.3%) had DM. Diabetic patients had also high prevalence of hypertension (90.6% vs 76.1%; p < .001) or renal disease (21.4% vs 15.9%; p < .001). After median follow-up of 1077 days (IQR 766-1113 days), diabetic patients had high total mortality (16.9%/year vs 11.4%/year; p < .001), cardiovascular mortality (9.1%/year vs 3.9%/year; p < .001) and MACE (12.9%/year vs 6.8%/year; p < .001). DM patients had poor anticoagulation control (time in therapeutic range: 58.52 ± 24.37% vs 62.68 ± 25.31%; p = .002). DM with lower TTR showed higher cardiovascular death and MACE. Multivariate analysis showed an independent association between DM and cardiovascular mortality [HR 1.73 (IC95% 1.07-2.80); p = .024]. CONCLUSION: AF Diabetic patients have higher comorbidities and poorer TTR than nondiabetic patients. Low TTR was associated with adverse events. The risk of cardiovascular outcomes was higher in DM patients, with independent association between DM and mortality risk.

Bioactive compounds in fruits from different regions of Brazil / Compuestos bioactivos en frutas de diferentes regiones del Brasil

It is important to determine the chemical composition of fruits in order to establish their potential health benefits for human nutrition and thus stimulate their cultivation and consumption. Therefore, the objective of this study was to determine the physical and chemical parameters, vitamin C content, phenolic compounds, flavonoids and carotenoids, fatty acid profile and antioxidant activity of fruits from different regions of Brazil. We observed that the different regions and fruits studied presented very distinct characteristics. For example, the cupuaçu pit is rich in unsaturated fatty acids, while the genipap and java plum presented high flavonoid content and the butia had a high concentration of carotenoids. Guava was the fruit with the highest antioxidant activity through the ABTS radical, while the yellow mombim presented the best response when the activity was determined by FRAP.

Es importante determinar la composición química de las frutas para establecer sus potenciales beneficios para la salud humana y, por lo tanto, estimular su cultivo y consumo. El objetivo de este estudio fue determinar parámetros físicos y químicos, el contenido de vitamina C, los compuestos fenólicos, los flavonoides y los carotenoides, el perfil de ácidos grasos y la actividad antioxidante de las frutas de diferentes regiones de Brasil. De los resultados obtenidos en este estudio se pudo observar que las diferentes regiones y frutas estudiadas presentaban características muy distintas, ya que la semilla de cupuaçu es rica en ácidos grasos insaturados, mientras que el genipapo y la ciruela java presentaron un alto contenido de flavonoides y el butia presentó alta concentración de carotenoides. La guayaba fue la fruta con la mayor actividad antioxidante determinada por el radical ABTS, mientras que el mombim amarillo presentó la mejor respuesta cuando la actividad fue determinada por FRAP
