Chokanan mango is one of the most popular cultivar in Malaysia. Juice processing application are gaining wide acceptance. Conventional thermal pasteurization is the pre- ferred technology to inactivate microorganisms and enzymes causing spoilage, thus prolonging the shelf life of juice. This studies on thermally treated fruit juices reported significant loss of nutritional quality and degradation of bioactive compounds such as ascorbic acid. The increasing demand for fresh-like fruit juice has spurred the development of non-thermal processing methods. Several studies using short-wave ultraviolet-c (UV-C) light treatment on fruit juices reported minimal changes in nutritional and quality attributes, and significant microbial inactivation.
