Abstract

The invention discloses a method for preparing concentrated cloudy jujube juice. The method takes dried jujubes as a raw material and comprises the following steps of washing and selecting the dried jujubes, pre-boiling the dried jujubes at the temperature of 95 DEG C in a continuous pre-boiling machine for 25-30 minutes, removing jujube stones, pulping, cooling pulp and carrying out pulp enzymolysis; separating to obtain raw cloudy jujube juice through a horizontal spiral separator; and carrying out disc separation and concentration to obtain the concentrated cloudy jujube juice with the soluble solid content of 60-65 Brix. The concentrated cloudy jujube juice is deep tea red, has a uniform color, thick jujube aroma, sweet taste and no off-smell, has trace amounts of sediments, does not have exogenous impurities, and does not contain chippings such as jujube peel and stones.

Description

technical field [0001] The invention belongs to the leading field of fruit and vegetable juice processing technology, and relates to a preparation method of concentrated jujube juice. Background technique [0002] Jujube is native to my country and has a cultivation history of more than 4,000 years.
