Abstract:

Using the new grapefruit variety that introduced in Fujian province as raw material, we studied the resin debitter technology for the grapefruit juice; The effcts of debitter of grapefruit juice were studied with various factors, including different amount of resin, temperature, time, pH value and so on; Based on the results of single factor tests, through orthogonal tests, the optimum conditions for the debittering of grapefruit juice using resin were as followings: under pH value of grapefruit raw juice, the optimun debittering temperature is 10℃, the amount of resin is 2.0%, the optimum time is 60mins; Using this technology, the debittering rate for the juice was 48.05%, and the juice was able to keep the flavor characteristics.
