Abstract:

The processing technique of compound functional drink made from Eucommia ulmoides Oliv. leaves was studied. Orthogonal design and fuzzy math were applied together to obtain the best prescription. The prescription of stabilizer was also determined by an orthogonal test design. The experimental results indicated that the best formula of the compound drink is as follows: 35% of mixed clear juice of Eucommia ulmoides Oliv. leaves, hawkthorn, medlar and pineapple (2:8:11:12, V/V) , 2.2% of sucrose, 2.2% of honey, 0.3% of citric acid potassium and 60.3% of water. While the formula of complex stabilizer is as follows: 0.20% of CMC-Na plus 0.03% of xanthan gum plus 0.15% of pectin.
