The invention discloses high-quality
physalis pubescens concentrated juice, a preparation method thereof and a
physalis pubescens compound beverage containing the high-quality
physalis pubescens concentrated juice, and relates to the technical field of
food engineering. The preparation method comprises composite enzymolysis before concentration, a color protection process in an enzymolysis process, a clarification process before concentration and a concentration process. In the
process optimization process, evaluation is carried out by taking the juice yield, the
browning degree, the light
transmittance and the
high concentration efficiency as evaluation indexes, and a good preparation process is obtained. Besides, the prepared
physalis pubescens concentrated juice and
raspberry juice are mixed, meanwhile,
cane sugar,
citric acid and a stabilizer CNC-Na are added, the
physalis pubescens-raspberry compound juice is prepared, the
physalis pubescens-raspberry compound juice is good in color and luster state and sour and sweet in taste, the physalis pubescens and raspberries are coordinated in taste, the tissue state is uniform and stable, and layering and
foreign matter are avoided.
