Efficacy of Ultraviolet Irradiation on shiga toxin Escherichia coli Inactivation of Pineapple-Mango Juice Blend
Publication Date : 07/02/2018
This study aims to evaluate the potential of ultraviolet irradiation treatment on shiga toxin E. coli O157:H7 in pineapple-mango juice blend as alternative to thermal pasteurization. Ultraviolet irradiation denotes as one of the non-thermal alternative technology for microbial inactivation in fruit juice processing. Tropical fruit well known with its unique flavor with pineapple and mango stands among the most popular tropical fruit. Pathogenic microorganism of E. coli O157:H7 in fruit juice able to cause fatality if consume. Pineapple and mango mixed together at ratio 70% pineapple and 30% mango. The result obtain indicates the efficiency of ultraviolet irradiation was comparable to thermal pasteurization as the shiga toxin E. coli O157:H7 reach 6 log reduction after treatment at ultraviolet dosage of 8.38mJ/cm². Ultraviolet irradiation proved to be promising in juice safety.
