    Abstract The consumption of rabbit meat is scarce in Mexico, despite its good taste and high protein content. Acid marination may be an option to introduce this meat into new markets and add value to this food. The use of ultrasound has been reported as an accelerator in the impregnation process and improving the product quality. The objective of this study was to evaluate the effect of acid marination assisted by power ultrasound on quality of rabbit meat. Marinating solutions were prepared with 70, 140, or 200 g NaCl/L, 3 g NaNO2, and 1.5% citric acid. Rabbit meat slices were immersed in every solution in static and ultrasonic bath at 40 kHz and 110 W of output power. Marinating time, NaCl concentration in the marinating solution, and US application increased weight losses and meat hardness but reduced water content, WHC, and pH. The color parameters L* and a* increased with the NaCl concentration in marinating solution and with the ultrasound application. NaCl content increased in meat with increased marinating time, NaCl concentration in marinating solutions, and higher rate in ultrasonic treatment. Application of ultrasound has high potential to be employed in the marinating of rabbit meat samples, diminishing the immersion time, and maintaining the quality.

    Abstract Agave syrup (AS) has recently gained popularity in the market for healthy, organic, functional, and diabetic foods. This trend is due to its natural origin and putative nutraceutical properties. However, the use of AS can be questioned regarding its elevated fructose concentration and its adverse effects on human health, rendering it similar to high-fructose corn syrup. This critical review aims at providing a broad overview of recent scientific research related to AS applications in the food industry and its health effects in consumers. According to the reviewed information, the manufacturing process employed to obtain AS affects its physicochemical and functional properties; therefore, the process variables need to be properly controlled. In the food industry, AS has been used in the bakery, confectionery, and functional beverage industries, due to its favorable technological properties. Despite possessing a small amount of natural compounds with possible nutritional, prebiotic, and bioactive properties, AS contains high concentration of fructose with potentially serious adverse effects on human health. Therefore, the challenge for AS production consists in finding such AS compositions that would allow for reducing the health risks and adverse effects of fructose intake while preserving its technological properties for food product development and maximizing the content of bioactive compounds with potentially beneficial properties. Finally, there is a need for close collaboration between the scientific community and food industry professionals in AS research, product development, and innovation, to increase the knowledge regarding the technological profile of AS and its adverse health effects on the consumers compared to other sweeteners on the market.

    Abstract This research aimed to evaluate the effect of different cooking methods (boiling, stir-frying, and steaming) on the microstructure, moisture, fat, protein, and glucose-derived carbohydrate contents, and the bioactive compounds (total carotenoids: CAR, total chlorophyll: CHLO, and total phenolic compounds: TPC) and antioxidant capacity (AC) of squash blossoms. Furthermore, we characterized polyphenolic compounds using HPLC and evaluated their bioaccessibility via in vitro digestions. Our results show that steaming and boiling do not affect moisture content. Only stir-frying decreased (p < 0.05) this parameter by 8 %. Additionally, the cooking methods increased (p < 0.05) protein and glucose-derived carbohydrate contents. All cooking methods changed the microstructure of the blossoms, probably due to the thermal and mechanical variations that result in moisture loss and degradation of cell wall components. As for the functional properties, boiling caused a greater loss of TPC (up to 96 %) and AC (up to 91 %). Stir-frying caused the greatest loss of CAR (up to 81 %) and CHLO (up to 84 %). The in vitro digestion assays showed changes in the bioaccessibility of CAR, CHLO, TPC, and AC in the cooked flowers compared to the fresh ones. Finally, kaempferol and gallic acid were the most resistant polyphenols to the cooking methods and in vitro digestion.

    Abstract Sustainable agriculture is the most desired solution to ensure food security for the growing world population and to face climate change. Furthermore, sustainable agriculture seeks alternatives to harmful pesticides and chemical fertilizers. This review presents an overview of recent scientific research and potential applications of volatile organic compounds (VOCs) as pest biocontrol and disease management during pre- and postharvest, along with possible limitations in scalability at the agricultural level. According to the information reviewed, bacteria, fungi, yeast, and plants are the principal organisms that produce VOCs with biotechnological potential. The main applications reported for VOCs are enhanced resistance/tolerance to abiotic stressors, such as drought, cold, and salinity, and an enhanced defense response against biotic stressors, such as viruses, bacteria, fungi, nematodes, and insects. Some VOCs in particular present an antimicrobial effect on a wide range of plant and human pathogens. Therefore, VOCs are considered a promising, sustainable biocontrol strategy that can replace pesticides and fertilizers. However, future research needs to promote collaboration with farmers and the development of applications for VOCs at the industrial level.

    Abstract Excess consumption of sweetened beverages is associated with a global rise in metabolic diseases. Tamarind and partially-hydrolyzed agave syrup have potential for developing healthier beverages. Our objective was to develop a functional beverage using these ingredients (PH-AS-B). We also evaluate shelf-life stability (physicochemical, microbiological, and antioxidant properties) and health effects in C57BL/6 mice compared with tamarind beverages sweetened with glucose or fructose. Optimal tamarind extraction conditions were a 1:10 ratio (g pulp/mL water) and boiling for 30 min, and the resulting beverage had a shelf life of two months at 4 °C. Non-volatile metabolites were identified using HPLC/MS. PH-AS-B was associated with decreased blood cholesterol (5%) and triglyceride (20-35%) concentrations in healthy mice as well as lower lipid (82%) concentrations and evidence of protein oxidation (42%) in the liver, compared with glucose- and fructose-sweetened tamarind beverages. In conclusion, PH-AS-B was stable and associated with beneficial metabolic properties in healthy mice.

    Abstract The presence of arsenic (As) in irrigation water is a threat to agricultural crops as well as human health. The presence of arsenic and phosphorous in irrigation water influences the behavior of bioaccumulation, biotransfer, and total bioactive compounds in the distinct parts of the onion structure. The present work evaluates the behavior of the bioaccumulation and biotransfer of As in the structures of onion (Allium cepa) through a composite central design and response surface method. The factors employed include the concentration of arsenic (V) and phosphate (V) in the nutritive solution. Additionally, this study analyzes the behavior of the effect that the induced stress has on the total bioactive compounds (phenols and flavonoids) and antioxidant capacity (ABTS and DPPH) in the onion roots. The results showed that the physiological properties, bioaccumulation factors, As transference, and the total bioactive compounds in the onion structure are affected by the competition of As and phosphates (P(V)) in the irrigation water. For concentrations of As and phosphorous of 450 μg L

    Abstract The aim of this work was to analyze the influence of brewing temperature and coffee particle size on the evolution of physicochemical, bioactive, and antioxidant properties of Mexican cold brew coffee (CBC). The brewing process was carried out at two extraction temperatures (10 ± 0.5°C and 25 ± 0.5°C) and two particle sizes: medium (MG, 0.70–1.70 mm) and fine (FG, 0.43–0.71 mm). CBC brewing showed a complex relationship between brewing temperature and coffee grind particle size. The increase in brewing temperature enhanced the extraction rate. However, the particle size conditioned the extraction equilibrium time and final CBC properties. MG accelerated the brewing extraction rates to reach equilibrium in CBC properties (~7 h for 25ºC and ~12 h for 10ºC), while FG induced slower extraction rates and prolonged extraction times (above 12 h for both temperatures). However, FG produced CBC with higher bioactive compound content, darker color, and slightly less acidity than MG.

    Abstract In recent decades, there has been a rise in the use of edible flowers in the world cuisine in order to make visually plain dishes more appealing. However, there is much more to flowers than just beauty. The traditional Mexican cuisine has made use of edible flowers for centuries and probably even millennia; in fact, many present-day Mexican dishes are still made with different parts of a variety of endemic edible flowers. In our review, we explore the most important Mexican edible flowers and their traditional use in the local cuisine. We first review the ancestral and present-day importance of flowers in Mexican culture to finally focus on nutrimental value and bioactive properties of edible flowers endemic to Mexico, including squash blossoms, coral tree flowers, yucca flowers, Mexican marigolds, dahlias, cactus flowers, funeral tree flowers, and others. We expose how these flowers are an integral part of Mexican culture and that they are typically cooked instead of being consumed raw. Moreover, our review shows that Mexican edible flowers also seem to be particularly rich in good quality protein and bioactive compounds with antioxidant activity that might be beneficial to human health.

    Abstract Nowadays, agave syrup (AS) is a controversial sweetener due to its high fructose content. However, the hydrolysis process to which AS is subjected could contribute to improving its functional properties. This work aimed to evaluate the relationship between the degree of hydrolysis (DH) of AS (95%: AS95, 88%: AS88, and 50%: AS50) and its functional properties. In addition, the impact of these properties on weight gain, blood biochemical parameters, and oxidative stress (lipids and proteins) was studied in C57BL/6 mice. By HPLC analysis, the main polyphenols identified in AS were catechin, chlorogenic acid, caffeic acid, vanillin, quercetin, naringin, rutin, ellagic acid, and gallic acid. As the DH of AS increased, its fructose concentration increased (p < 0.05), and its concentration of fructans, bioactive compounds (BC), and antioxidant capacity decreased. In the case of blood glucose, the mice drinking AS solutions did not present differences (p > 0.05) in comparison to the control (water). However, mice drinking AS50 solutions showed a decrease (p < 0.05) in weight gain (35%), cholesterol (6%), triglycerides (18–22%), and oxidative stress in lipids (63%) and proteins (44%) compared to mice drinking AS88 and AS95 solutions.

    Abstract Arsenic (As) is a natural contaminant that exists naturally in the earth crust and it is toxic to plant cells. Studies involving the absorption of As by plants have already been described previously. Recently, researchers have intended to understand the molecular and physiological mechanisms that intervene and interact in As absorption. The study of the metabolome in plants under As stress makes use of advances in instrumentation and analytical equipment that allows for metabolomics to be performed. The aim of this comprehensive review is to provide a revision of metabolomic studies related to As-induced stress in plants and the main alterations in its metabolism compared to a non-stress situation. According to the reviewed research, As affects both primary and secondary metabolism, with amino acids, proteins, and the antioxidant complex enzymes being the molecules most studied and related to As stress. However, non-enzymatic compounds, derived from the secondary metabolism, have been scarcely studied in metabolomic studies on As-induced stress in plants. In conclusion, metabolomics as a research approach to studying As stress in plants could permit in-depth understanding of As-related behavior in the plant metabolism
