Abstract:

Objective: To develop gamma aminobutyric acid (GABA)-rich beverage by Monascus fermentation with bloodpressure- lowering function. Methods: Orthogonal experiments were performed to determine the optimal processing parameters for the fermented functional beverage. Results: The optimal formula of raw materials was composed of 50% green tea juice, 8% chrysanthemum extract and 14% lotus leaf-hawthorn-corn extract. Meanwhile, the optimal accessory materials for taste adjustment were 70 g white sugar, 0.4 mL of essential oil, 3 mLof anti-oxidant and 350 mL of tea juice in 1000 mL of fermented beverage. Conclusion: The prepared beverage contains GABA up to 0.26 g/L and achieved the excellent level in color, smelling and taste.

Key words: Monascus, gamma aminobutyric acid, blood pressure lowering, beverage
