Abstract

The invention discloses a preparation method of a red date enzyme, adopting enzymolysis-coupling fermentation production technology. The preparation method comprises the following steps: (1) pulp preparation: cleaning selected red dates and carrying out pulp preparation to obtain red date pulp; (2) enzymolysis: adjusting the red date pulp to a pH value of 5.0-6.5 and a temperature of 25-50 DEG C,adding a complex enzyme at least consisting of rhamnosan degrading enzyme, pectinase, dextranase and galactosidase, and carrying out enzymolysis for 1-3 hours; (3) coupling fermentation: preparing lactobacillus rhamnosus into bacterial suspension of 10<4>-10<8> CFU / mL by using sterile normal saline; when the enzymolysis lasts for 1-3 hours, inoculating the lactobacillus rhamnosus aseptically, stirring the mixture, carrying out static culture for 12-48 hours, and stopping fermentation when the pH value is 3.5-4.5; and (4) post-treatment: carrying out solid-liquid separation on the enzyme fermented in the step (3) to obtain liquid red date enzyme. The method disclosed by the invention adopts the enzymolysis-coupling fermentation production technology, thus improving the utilization rates ofred date components and the yields of the enzyme and prebiotics.

Description

technical field

[0001] The invention relates to a preparation method of jujube enzyme. Background technique

[0002] Red jujube, also known as jujube, is a plant of Rhamnaceae (Rhamnaceae). It is sweet in taste and warm in nature, and it belongs to the spleen and stomach meridian. Modern pharmacology has found that jujube contains polyphenols, active polysaccharides, pentacyclic triterpenoids, cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate (cGMP) and other biologically active substances, which have the functions of nourishing blood, Calms the mind and calms the nerves, improves intelligence and brain, fights cancer, protects the liver, invigorates the spleen and strengthens the body, and improves myocardial nutrition. It is also rich in amino acids (18 kinds), multivitamins and mineral elements, with extremely high nutritional value.

[0003] China's jujube processing is mostly crude products, and there are few intensive and deep processed products...
