The invention discloses an improved medicinal and edible
plant beverage based on ancient seven-white drink and a preparation method thereof, and belongs to the technical field of
food processing. Aiming at the problems that the existing seven-white beverage is rough in taste, obvious in granular
sensation, easy to layer and precipitate at normal temperature and insufficient in
aroma coordination, and needs to depend on food additives to maintain
system stability, the preparation method comprises the following steps: baking peeled
sweet almonds at a high temperature of 145-155 DEG C for 10-12 minutes to enhance
aroma, performing step-by-step constant-temperature
water extraction on bighead atractylodes
rhizome and white paeony root, and performing wet-process ultramicro pulping on the rest raw materials, thereby obtaining the seven-white beverage. According to the invention, fructo-
oligosaccharide and natural honey are taken as raw materials, secondary high-pressure homogenization, ultrahigh-temperature instantaneous sterilization and sterile hot filling are matched, conventional blending and low-temperature post-addition processes are respectively adopted for fructo-
oligosaccharide and natural honey, and on the premise of not adding preservatives, essences, synthetic pigments, thickeners and stabilizers, the beverage
system is stable, the taste is fine and smooth, and the natural fragrance is soft. The process parameters are standardized, the industrial amplification can be realized, the industrial problem of insufficient stability of the zero-additive
plant beverage is solved through a pure physical process, and the industrial practicability is outstanding.
