ArticleItem Unknown MICROBIAL INACTIVATION IN RAW PROCESSED BY HURDLE TECHNOLOGY(2018) Shivani Indumathi, A; Sujatha, G; Baskaran, D; Dhanalakshmi, B; Serma Saravana Pandian, A; TANUVASInactivation of microorganisms exposed to Hurdle technology (HT) is a promising food preservation technology. This paper demonstrates and validates the inactivation of microorganism in raw milk subjected to combined effect of pulsed electric field and mild heat. The raw milk was preheated to 40°C and 50°C before it was subjected to various voltage gradients viz., 10KV/cm, 20KV/cm and 30KV/cm with different treatment time viz., 3 and 6 minutes. The pasteurized milk samples were taken as control samples. The HT treated samples were compared with pasteurized (control) milk samples to determine the efficacy of HT treatment. The initial microbial load present in the raw milk was 6x106 cfu/ml whereas the microbial load present in the control samples were 3x104cfu/ml. It was found that the standard plate count values were highly significant (p<0.01) in HT treated samples when compared to control samples. It was also found that there was significant difference in standard plate count values between treatments. It was observed that the E.coli was not present in HT treated samples and during the storage period.
