Study on the Processing Technology of Functional Drink with Trifolium pratense

Objective] To prepare a functional drink with antioxidant and sleep improvement activities using Trifolium pratense after the optimization of formula and processing technology. Method] Based on the Implementation Manual of Technical Standards for Testing and Assessment of Health Food, the optimal processing technology and parameters were obtained by preparing the clover extract and other ingredients. Result] The results showed that the optimal processing parameters were 40% alcohol as extraction solvent twice, extraction tem- perature 80℃, and the sterilization at 100℃ for 15min. The optimal formula of this beverage was lOmL of clover extract solution, 12. Og of su- crose, 0. 4mL of 50% citric acid, 0. 03g sodium benzoate, and 100mg vitamin C in 200rnL beverage. Conclusion] Clover functional beverage had distinctive color, rich clover flavor, and excellent taste, which was a promising functional drink for improving peoples＇ health.
