Abstract:

In this study, a compound health beverage was developed with dandelion and hawthorn as raw material. The results showed that the optimal extraction conditions of hawthorn juice are softening hawthorn at 80 to 90 ℃ for 20 to 25 min, and extracting hawthorn for 10 h at 90 ℃ at the material-liquid ratio of 1:5.5. 0.2% ascorbic acid plus 0.2% EDTA-2Na is the best color fixative for dandelion. The optimized formula of compound health beverage through orthogonal test is 40% of dandelion juice, 25% of hawthorn juice, 10% of sugar and 0.2% of acid (citric acid). The gelatin-tannate method is mostly suitable to clarify the compound health beverage. The beverage product has rich nutrition and unique flavor.
