Organic acid incorporated chitosan films for dried anchovy

Researchers at the Central Institute of Fisheries Technology in India prepared antimicrobial chitosan films with acetic acid and propionic acid with glycerol as plasticizer and its efficiency was compared with polyester-polyethylene laminate (PEST/LDPE). The tensile strength of acetic acid/chitosan (ACS) films were higher than propionic acid/chitosan (PCS) films.
In terms of microbial and chemical indices, anchovies wrapped in ACS and PCS films were superior to those wrapped with PEST/LDPE films during storage. The study revealed the suitability of chitosan film as wraps for increasing storage stability of dried fish. An article about the research is published in Carbohydrate Polymers.
