Abstract
Antimicrobial chitosan films were prepared with acetic acid and propionic acid with glycerol as plasticizerand its efficiency was compared with polyester-polyethylene laminate (PEST/LDPE). The tensile strengthof acetic acid/chitosan (ACS) films were higher than propionic acid/chitosan (PCS) films. The elongationpercentage (6.43–11.3) and water vapour permeability (0.015–0.03 g/m2/day) were significantly lower(p < 0.05) for chitosan films when compared to control. Oxygen transmission rate (OTR) of control andpropionic 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 forthree months. Quality indices like peroxide value (PV), thiobarbituric acid value (TBA) and microbiologicalparameters 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 tothose wrapped with PEST/LDPE films during storage. Study revealed the suitability of chitosan film aswraps for increasing storage stability of dried fish.
