Resumen en español

La miel es un producto alimenticio con alto valor nutricional y potencial farmacológico. La mayoría de los estudios de este producto se han centrado en las propiedades de la miel producida por Apis mellifera, que se ha utilizado en medicina alternativa, destacando por sus actividades antioxidantes, antimicrobianas y antiinflamatorias, entre otras. En este trabajo, se identificó el origen floral, la concentración de proteína soluble, los compuestos fenólicos y la actividad antioxidante y quelante de metales de las mieles producidas por Melipona beecheii y Frieseomelitta nigra,originarias de San Marcos, comunidad de Tenosique en Tabasco, México. Los resultados muestran que la miel producida por F. nigra es de origen polifloral derivada principalmente de la especie Piper sp., Aff. Brosimum, Asteraceae, Ziziphus sp., Haematoxylum campechianum, mientras que la producida por M. beecheii fue monofloral (Eugenia sp.). La miel de F. nigra presentó mayor concentración de compuestos fenólicos y mayor efectividad para atrapar los radicales superóxido y DPPH, además de un mejor potencial de quelación del cobre. Por su parte, la miel de M. beecheii presentó mayor capacidad de captación de los radicales ABTS y quelación del hierro; mientras que la capacidad de absorción del radical hidroxilo fue similar para ambas mieles. Este trabajo resalta la importancia de contar con análisis palinológicos y bioquímicos sobre las mieles de las abejas nativas sin aguijón por el potencial terapéutico que tienen y de las cuales, en el caso de algunas especies, no se tiene información.

Resumen en inglés

Honey is a food product with high nutritional and pharmacological value. Most studies of this product have focused on studying the properties of honey produced by Apis mellifera, which has been used in alternative medicine, highlighting the antioxidant, antimicrobial and anti-inflammatory activities, among others. In this work, we identified the floral origin, the concentration of soluble protein and phenolic compounds, and we assessed the antioxidant and chelating activity of the honey produced by Melipona beecheii and Frieseomelitta nigra from the community of San Marcos in Tenosique, Tabasco, México. The results show that the honey produced by M. beecheii was of monofloral origin (Eugenia sp.); while that of F. nigra is of polyfloral origin, derived mainly from the species Piper sp., Aff. Brosimum, Asteraceae, Ziziphus sp., Haematoxylum campechianum). Honey produced by F. nigra show higher concentration of phenolic compounds, it is more effective in entrapping the DPPH and superoxide radicals, and exhibits better copper chelating potential. The honey of M. beecheii has a higher capacity for uptake of ABTS radicals and chelation of iron. The uptake capacity of the hydroxyl radical was similar for both honeys. This work highlights the importance of having palynological and biochemical analyzes on the honeys of native stingless bees, because of their therapeutic potential, where for many species there is a lack of information.

Resumen en inglés

Due high proportion of oil in Jatropha curcas seed (50–60%), it is interest to identify methods for their extraction. In addition, the residual paste is rich in proteins and could beused safely as raw matter for other processes. In the present work, we propose the use ofa crude pineapple green extract (Ananas comosus L.) with a high content of enzymes with different proteolytic activities (1.18–5.90 IUT) to extract oil. A comparative extraction was made between the enzymatic treatment, a microwaves heat treatmet, the combination of both methods and the Soxhlet extraction. The oil yield with the crude extract, after 6 h of enzymatic hydrolysis was 46.9%, whereas after microwaving (3 min), the enzymatic hydrolysis treatment increased the yield to 54%. Oil was characterized physicochemically without showing difference between treatments. Fatty acids present in the J. curcas oil are the unsaturated fatty acids: oleic, linoleic, palmitoleic, as well as saturated ones like palmitic, stearic,and myristic. The use of enzymatic extracts combined with microwaves is a good alternative to improve the yields without altering the chemical and physical characteristics of the Jatropha oil.

Evidence of the role that dietary carbohydrates (total carbohydrates, dietary fiber, total sugars, dietary glycemic index (GI) and glycemic load (GL)) exerts on insulin levels in adolescents is controversial. Thus, the aim of this study was to assess the association between dietary carbohydrates and insulin resistance in adolescents from Chiapas, México. A cross-sectional study was conducted in 217 adolescents. Sociodemographic, anthropometric, dietary and biochemical data were obtained. Total carbohydrates, dietary fiber, total sugars, dietary GI and GL were calculated from 24 h recalls. Two validated cut-off points for the homeostasis model assessment of insulin resistance (HOMA-IR) were used as surrogates of insulin resistance. Fasting insulin levels≥14.38 µU/mL were considered as abnormal. Multivariate logistic regression models were fitted to assess the association between tertiles of dietary carbohydrates and insulin resistance or hyperinsulinemia. In our study, adolescents with the highest dietary fiber intake had lower odds of HOMA-IR>2.97(OR=0.34; 95% CI:0.13–0.93) when adjusted for sex, age, body fat percentage and saturated fatty acids intake. No significant associations were found for the rest of the carbohydrate variables. In summary, high-fiber diets reduce the probability of insulin resistance in adolescents from marginalized areas of Chiapas, México.

Resumen en inglés

Jatropha curcas seeds are an important source of oil (5-60%), used to obtain biodiesel. The generated residual paste has a high concentration of proteins (50-55%); however, the seeds contain non-nutritional factors that limit their use. The objective of this work was to analyze the effect on the physicochemical properties of the oil obtained from J. curcas seeds subjected to different thermal treatments and to evaluate the biological quality of the proteins contained in the residual cake. The best extraction of oil (95%) was obtained after 10 h from roasted or boiled seeds. In the oil from roasted samples, the acid index increased significantly (p ≤ 0.05) with respect to the untreated sample, whereas the iodine index increased significantly (p ≤ 0.05) in the oil extracted from the boiled samples. With respect to the proximal chemical composition of the flour, roasting and boiling treatments allowed for greater oil extraction (97 and 92%), achieving, in turn, a higher content of proteins (59.56 and 58.5 g/100 g) and fiber (6.67 and 6.67 g/100 g), and lower activity of trypsin inhibitors (45 and 38%) and phytates (63 and 72%), respectively. According to the in vivo biological quality test, conducted on Wistar rats, the thermal treatments applied to the seeds improved digestibility (> 70%) and the protein efficiency index (PER). The thermal treatment allowed extracting more efficiently the oil and improved the quality of the proteins present in the residual paste.

Resumen en inglés

The composition of the soil affects the physicochemical properties of oil and seed of pinion; this has been evidenced in studies done in seeds of the states of Morelos, Sinaloa, Veracruz, and Tamaulipas, among others; however, there are no reports of evaluation of this species in Tabasco, a state with potential for the intensive production of this species. The physicochemical characteristics of the seeds and the oil of seeds harvested in the localities of Huimanguillo and Mantilla, Cunduacán, Tabasco, were evaluated. The seeds from Huimanguillo showed better physical characteristics: viz., seed weight (0.94 ± 0.099 g), length (19.7 ± 0.6 mm), and width (10.92 ± 0.3 mm); in addition their protein and oil content are higher than in the seeds harvested in Mantilla. However, the concentration of protein presented was lower than in any of the seeds grown in other states. These said materials could be recommended for the biodiesel industry because of its high oil content and valuable physicochemical characteristics, which supports that the state of Tabasco has ideal ecoclimatic characteristics suitable for cultivation. The results obtained from the oil analysis show no significant difference in the values of acidity, saponification, peroxide, iodine, viscosity, and specific density compared to the oils obtained in the different locations of this study. The fatty acid profile indicated a greater quantity of oleic and linoleic acid (34–36.5%) and a low content of myristic acid (1.1–1.5%) and palmitoleic acid (1.3–2.4%).

Chickpea has been classified as a nutraceutical food due to its phytochemical compounds, showing antioxidant, anti-inflammatory, and anticancer activity. To investigate this, we evaluated the e ect of cooking on the nutritional and non-nutritional composition and the in vitro and in vivo antioxidant activity of chickpea seed. The latter was determined by the variation in the concentration of nitric oxide (NO), oxidized carbonyl groups (CO), malondialdehyde (MDA), and the expression of 4-hydroxy-2-nonenal (4-HNE) in the colon of male BALB/c mice fed with a standard diet with 10 and 20% cooked chickpea (CC).We induced colon cancer in mice by administering azoxymethane/dextran sulfate sodium (AOM/DSS); for the evaluation, these were sacrificed 1, 7, and 14 weeks after the induction. Results show that cooking does not significantly modify (p < 0.05) nutritional compounds; however, it decreases the concentration of non-nutritional ones and, consequently, in vitro antioxidant activity. The in vivo evaluation showed that animals administered with AOM/DSS presented higher concentrations of NO, CO, MDA, and 4-HNE than those in animals without AOM/DSS administration. However, in the three evaluated times, these markers were significantly reduced (p < 0.05) with CC consumption. The best e ect on the oxidation markers was with the 20% CC diet, demonstrating the antioxidant potential of CC.

¿Comer un caldo tlalpeño o una ración de pollo “Kentucky”? Dado que “somos lo que comemos”, el exceso de productos procesados podría ligarse al aumento de enfermedades crónicas no transmisibles, como obesidad o cáncer. La nutrición genómica o nutrigenómica explica la interacción entre constitución genética, salud y composición de los alimentos; entender esto debería impulsarnos a preferir alimentos tradicionales como la mejor opción para nuestra dieta.
