A fresh vegetable and fruit juice has become a new healthy food available for detoxification, dieting and health. This paper presents the useful information about the quality changes of fresh juice according to different juicer. Quality of fresh juice could be evaluated by several factors such as juice yield, enzyme activity, antioxidant activity, polyphenol contents, and anti-inflammatory activity. The juice yields of 12 different vegetables and fruits were compared using 6 different juicers and it was observed that the yield of slow juicer was better than that of conventional blender. Among 12 samples, the juice yield of grape is the best and the pH of the juice was in the acidic range of 3 and 4. Kiwi and grapefruit were the best in terms of protease enzyme activities by Hemoglobin units on the tyrosine basis and Spectrophotometric acid protease unit and papain units on the tyrosine basis of KFDA protocols. The total polyphenol contents were also high in kiwi and grapefruit. The antioxidant activity by diphenyl-1-picrylhydrazyl (DPPH), superoxide dismutase (SOD), and radical scavenging assay were high in the order of kiwi, grapefruit, grape, tomato, and orange. Anti-inflammatory activities were also assay for 12 samples with 6 juicers. It can be concluded that of fresh fruit and vegetable juice provides a source of antioxidant components and enzymes with high activity. And the enzyme activities could be used as one of the quality indicator of fresh juice. Concerning the juicers used in this study, slow juicer could be recommended to prepare the fresh juice in terms of the juice quality.
