title: Packaging performance of organic acid incorporated chitosan films on dried anchovy (Stolephorus indicus).
abstract: Antimicrobial chitosan films were prepared 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. The elongation percentage (6.43-11.3) and water vapour permeability (0.015-0.03 g/m(2)/day) were significantly lower (p<0.05) for chitosan films when compared to control. Oxygen transmission rate (OTR) of control and propionic acid/chitosan (PCS) films were significantly higher (p<0.05) than acetic acid/chitosan (ACS) films. Dried anchovy (Stolephorus indicus) wrapped in these films were stored at ambient temperature for three months. Quality indices like peroxide value (PV), thiobarbituric acid value (TBA) and microbiological parameters such as aerobic plate count (APC) and total fungal count (TFC) were periodically determined. 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. Study revealed the suitability of chitosan film as wraps for increasing storage stability of dried fish.
