Effects of ultraviolet radiation on the microbiological, physicochemical, and sensory properties of Rangpur lime juice
Acevedo, B.A1, Sgroppo, S.C2, Dellacassa, E3.
Rangpur lime juice was subjected to ultraviolet (UV) radiation as a non-thermal technology and changes in/on quality characteristics (microbiological, physicochemical and sensorial) were determined in order to extend its shelf life. UV-C treated juice resulted in 2.33 log and 2 log reductions in aciduric microorganisms and yeast and mould count, respectively. After UV-C treatment, there were no significant changes (p > 0.05) in pH, acidity and soluble solids; however antioxidant activity and the ascorbic acid content were affected by this process. The losses in ascorbic acid were 27.5 and 42% after UV-C treatment necessary to decrease 95 and 99% of the microbial load, respectively. Based on sensory analysis results, no significant differences were detected between fresh and UV-C treated juices. UV-C treatment extended the shelf life of fresh juice to 5 days during storage at 4°C.
