Naringinase is a kind of glycosidase complex, which composed ofα-L-rhamnosidase (EC 3.2.1.40) andβ-D-glucosidase (EC 3.2.1.21). Naringinase can specifically hydrolyze naringin into naringenin and it has many important application value, such as debittering of citrus fruit juice, increasing beverage aroma, industrial preparation of rhamnosidase and flavonoids.
