摘要:Abstract(#br)The aim of this study was to prepare chitosan (CS) edible films containing shrimp carotenoproteins (CP) and plasticized with glycerol and polyvinyl alcohol (PVA) using the casting method. The effects of CS (1–3%), glycerol (0–10%) and CP (0–3%) amounts on m...

摘要:Abstract(#br)Chitin was recovered through enzymatic deproteinization of the shrimp processing by-products. Different microbial and fish viscera proteases were tested for their deproteinization efficiency. High levels of protein removal of about 77 ± 3% and 78 ± 2% were recor...

摘要:Abstract(#br)Chitosan is obtained by deacetylation of chitin. Chitosan versatility is directly related to the polymer's characteristics depending on the deacetylation process. The aim of this research was to study the parameters influencing deacetylation and to elucidate the...

摘要:Abstract(#br)Chitin and derivatives used for biomedical or pharmaceutical applications require a high level of purity and quality that are difficult to achieve. In this study, we propose to optimize the extraction of chitin in order to obtain pure product keeping a structure...

摘要:Abstract(#br)The results given in the literature are conflicting when considering the relationship between antimicrobial activity and chitosan characteristics. To be able to clarify, we prepared fifteen homogeneous chitosans with different acetylation degrees (DA) and molecular w...
