Abstract:

In the present study, naringinase, an enzyme that hydrolyzes naringin responsible for bitter taste, was used to debitter Citrus grandis (L.) Osbeck cv. Guanximiyou (Guanxi pomelo) juice. To maximize the removal rate of naringin from Guanxi pomelo juice, major hydrolysis parameters including enzyme dosage, reaction temperature and time and pH were investigated by single factor and orthogonal array design methods. Naringin in Guanxi pomelo juice was analyzed by reversed phase high performance liquid chromatographic method. Results indicated that a maximum removal rate of naringin of more than 97% was achieved by using 7.4 U/mL of naringinase to treat Guanxi pomelo juice for 100 min at 60 ℃ and pH 3.6.

Key words: Guanxi pomelo, juice, naringinase, naringenin, debittering
