Evaluation of the effect of chitosan loaded with Natamaycin nanoparticles, lysozyme and acetic acid on shelf life of Siberian Sturgeon (Acipenser baeri) Caviar
Caviar is one of the most important export products of Iran's fisheries industry. Because of the unpasteurized nature of the process, it is very vulnerable to spoilage. This study was carried out to evaluate the feasibility of chitosan, a natural antimicrobial substance which combined with othe...

The effect of chitosan coating was carefully studied within 150 days storage time at zero to -3 ° C in a standard situation.
