Alpha cultivar is the main potato crop merchandized in Mexico for direct consumption and processing. This tuber is susceptible to enzymatic browning, affecting its quality and consumer's acceptability. On the other hand, low-temperature storage induce reducing sugar synthesis, hence altering potato flavor and texture. Storage of several fruits and vegetables...
The production of caffeoyl, feruloyl and p-coumaroyl estereases from different carbon sources was studied. An spectrophotometric technique which simultaneouly monitors substrate and product in a reaction system was developed for analysing the caffeoyl esterase I, caffeoyl esterase 11, feruloyl esterase and p-coumaroyl activities. In order to select a producer strain...
Bigels (BG) or hybrid gels are formed from the mixture of two gel phases, oleogel (OG) and hydrogel (HG). Recent research has reported that these systems have great applications potential in the food industry, mainly in the protection, release and controlled delivery of bioactive compounds, displaying superior functional properties than...
En el último siglo, con la mejora de las condiciones sanitarias, el mundo ha sufrido una transición epidemiológica, pasando de las enfermedades infecciosas y deficiencias nutricionales a enfermedades crónicas no transmisibles, como la diabetes mellitus, las enfermedades cardiovasculares y el cáncer. Debido a que hoy en día los tratamientos existentes...
Emulsiones múltiples agua-aceite-agua (W1/O/W2) con un contenido 25 y 35% de sólidos fueron secadas por aspersión produciendo microcápsulas con relaciones de mezcla de material de pared a emulsión primaria de 3.9:1, 2.6:1 y 1.4:1. Las microcápsulas tuvieron un contenido total de carotenoides de 0.25% (peso/peso). Los carotenoides utilizados consistieron de...
There is currently a growing demand for functional foods containing ingredients and additives (natural colorants), but the latter are expensive and difficult to standardize since they come from a vegetable source (fruits, vegetables, flowers, among others), as they depend on seasonality, growing conditions and extraction methods. In Mexico, there are...
En este trabajo se estudió el efecto que tiene la fuente de nitrógeno en la expresión de las distintas lacasas del hongo termo tolerante Trametes sp. EUM1. También se identificó en cuales extractos existían las isoformas con mayor estabilidad térmica. Este estudio radica en la necesidad de encontrar condiciones de...
Este trabajo tuvo como propósito producir y caracterización un extracto enzimático con actividad feruloil esterasa y pectinasa a partir de un hongo filamentoso por fermentación en medio sólido utilizando como sustrato pulpa de café. A partir de una colección de 13 hongos filamentosos, pertenecientes principalmente a los géneros Aspergillus y...
Lactobacillus casei was entrapped in beads made with sodium alginate (A), amidated low-methoxyl pectin (P), and blends of A-P (1:2, 1:4, 1:6 ratios) by the extrusion technique. Diameter, sphericity and textural properties of the beads and the survivability of entrapped Lb. casei during yoghurt storage and in simulated gastrointestinal conditions...
Colecciones 2 diabetes (T2D) is a disease with a high prevalence in the world population. This condition is characterized by increased blood glucose, glucose intolerance, and progressive insulin resistance. Currently, there is a battery of drugs called oral antidiabetics whose objective is to decrease capillary glucose, treatments that are used...
