Abstract

Red pepper is utilized as a single flavor or in combination with other spices. This spice contains capsaicin, Carotenoid pigment and high Ascorbic acid level which have proper health and Anti-cancer effects on it. Normally this product is replete with microbial load and pathogens prior to applying any decontamination methods that could threaten human life. So creating a new approach for microbial decontamination of whole dry red pepper is obligatory, which is applying steam and microwave together. Here, saturated steam and microwave heat is used for 10 minutes with 720 watts and for 90 seconds respectively, while microbial load, enzymatic activities, moisture content and color alternation were monitored. Finally it was observed that processed red pepper contains the minimal microbial load and lacks any enzymatic activities, even in comparison with applying gamma irradiation with 5KGy in which enzyme activity was noticeably seen.
