Evaluation of capsaicinoids extracts as bioactive substance for antimicrobial films

摘要: Capsaicinoid, a naturally occurring alkaloid group and active components which can be found in chili peppers variety (Capsicum spp.), contributes to the pungency, taste, aroma of peppers. Apart from their culinary medicinal properties, capsaicinoid functions as antioxidant agent food preservation. In current research, evaluation bio-active substance was carried out determine its potential development antimicrobial film for packaging. A mixture acetone: petroleum ether (1:1) had been used extracting capsaicinoids carotenoids (natural red pigment).The four types pepper studied were Green Malagueta Salvador, Red Thai Capsicum Frutescens Cayenne. The optimum extraction time amount (color intensity) each studied. Lastly, properties AM films determined they inhibited both gram-positive (Streptococcus B. subtilis) gram-negative (E. coli) bacteria successfully through agar diffusion test liquid culture test.
