Production technology of Prunus Tomentosa Thunb juice carbonic acid drink

This paper analyses the nourishment components of Purnus Tomentosa Thunb, and effect of pectinase Rohanpect D5S on Prunus Tomentosa Thunb's juice yield, viscosity, clarificaiton. The results show that, Prunus Tomentosa Thunb is rich in mineral materials and vitamins. Production by using compound pectinase has significant effect on juice yield. The highest rate is 72.8% in the condition of 6% enzyme in concentration, 45℃ in processing temperature and 60 minutes in processing time, which is 11.6% higher than that of comparison group. The enzyme concentration can greatly decrease juice stickiness, and increase clarificaiton. The paper also puts forward the optimal formula of Prunus Tomentosa Thunb juice carbonic acid drink.
