The use of preservatives has become indispensable to extend the shelf life of foods. However, uncertainty about the toxicity and safety of the use of synthetic preservatives has led the population to demand more natural ingredients for food preservation. There are naturally occurring substances in plants with high antioxidant and antimicrobial capa...

Beverages are natural or artificial liquid substances, which may or may not contain nutrients, used for human consumption, and there are two types, alcoholic and nonalcoholic beverages. Nonalcoholic beverages include functional beverages, which contain bioactive compounds that confer health benefits in addition to essential nutrients. The growing n...

Passion fruit (Passiflora edulis f. flavicarpa Degener) is not widely traded due to its short shelf life. Edible coatings can be used to extend the postharvest life of fruits. The objective of this study was to develop a candelilla wax-based coating (Euphorbia antisyphilitica Zucc) for the preservation of passion fruit. Three coating formulations (...

The thin-layer chromatography technique (TLC) is a simple and inexpensive analysis commonly used to identify qualitatively the presence of carbohydrates in food samples such as mono- di and oligosaccharides particularly. TLC assay could be improved using image processing software for the semiquantitative determination of this type of compound. In t...

Procyanidins are bioactive molecules with industrial and pharmaceutical relevance, they are present in recalcitrant agro-industrial wastes that are difficult to degrade. In this study, we evaluated the potential consumption of procyanidins from Aspergillus niger and Trichoderma harzianum strains in submerged fermentations. For this purpose, a cultu...
