Abstract:
In order to promote the development and utilization of
Gynura bicolor, the processing technology of
Gynura bicolor compound beverage was studied. The sensory evaluation was taken as the index, and the optimum proportion of
Gynura bicolor compound beverage was determined by single factor test and orthogonal test. The test results showed that the optimum ratio of
water extract of Gynura bicolor
:red grape juice:blueberry juice for Gynura bicolor was 4:1:2, original solution 700 g·kg
-1, sucrose 80 g·kg
-1, citric acid 0.4 g·kg
-1 and sodium citrate 0.3 g·kg
-1. Among them, the amount of sucrose was the significant influencing factor (
P<0.05), the concocted compound beverage of
Gynura bicolor was sweet and sour, with special flavor and attractive color.
