matrix in this study. Stewed-pork immersed in CHI and/or GOG
solutions could reduce the values of pH, TVB-N, POV, TBA and total
bacterial count during 12 days of refrigerated storage. Chitosan
revealed better antibacteria but weaker antioxidation than GOG.
CHI combined GOG had possible synergistic effect on antioxidation
and microbial inhibition for stewed-pork preservation. Specifically,
5% aqueous extract of ginger, onion and garlic–0.5% chitosan
(Mix2) could be used as natural antioxidants in cooked pork
products.
