Chitin is one of the most abundant biopolymers on earth together and with the chitosan, its main derivative, they have shown several applications. Shrimp wastes represent a source of chitin that allows recovery of this compound and this process resolves an environmental problem. Chitin and chitosan are produced industrially by...
La quitina, biopolímero componente del exoesqueleto de crustáceos, se extrae comúnmente mediante métodos químicos, lo que genera problemas ambientales así como disminución del peso molecular de la quitina disminuyendo sus aplicaciones posteriores. En virtud de lo anterior, el presente trabajo estudió la extracción biológica de quitina mediante fermentación con dos...
The pitaya (Stenocereus pruinosus) and sweet xoconostle (Stenocereus stellatus) are endemic fruits of Mexico with local distribution, due to their perishability and microbial decay. Therefore the objective of this work was the evaluation of biopolymer coatings for extending postharvest life and microbial inhibition. Chitosan (Q) was obtained by thermochemical heterogeneous...
La celulosa es el polisacárido más abundante en la naturaleza, el cual puede ser sintetizado por bacterias del género Gluconacetobacter spp. como parte de su proceso metabólico para llegar a las superficies donde el oxígeno es abundante facilitando así su supervivencia. Gluconacetobacter xylinus es un microorganismo ampliamente estudiado para la...
The development of edible coatings based on biopolymers has been applied for resh fruit and vegetable products, therefore it is of great interest on the quest of materials with null toxicity, biodegradable and biocompatible, whose objective is increasing the storage life preserving the quality characteristics. In this regard, Chitosan (CS)...
