Bioprocessing of resu00ecduos shrimp to obtain chitin, chitosan, proteins, pigments and calcium carbonates

摘要

Bioprocessing of shrimp waste to obtain chitin, chitosan, proteins, pigments and calcium carbonates.The present invention patent has as its goal the bioprocessing of shrimp waste, preferably the head of shrimp, Litopenaeus species vanflamei or other crustaceans (crab and lobster), through the semi solid fermentation to obtain chitin, and secundari One for the recovery of proteins, pigments and calcium carbonate with a strain of Lactobacilius sp.Nomeadarecovery, isolated from a sample of cheese curd regional. Was used as carbon source sucrose, can be used in other types of sugars such as glucose, fructose, xylose, or by-products of the food industry.Chitosan can be produced from chitin obtained by fermentation with different degrees of desacetilau00e7u00e3o through treatment with NaOH solution under vacuum and subsequent heating to 60 - 80 C 198 198 C for 1 h.
