Benefits of technology

In this patented new way we created an improved type of sweetener called Red Jujuan (RJ). Unlike regular sweetening agents like sugar or glucose, these sugars have very little calorie value compared to sucrose. They contain many important carbohydrates such as fructans, lignin, cellulosic amino acids, gums, proteins, etc., making them ideal food sources due their unique flavor profile. By adding certain chemical substances they break down quickly during heat treatment, resulting in more efficient processes for producing highly solubilile blue vegetable drinkings with excellent taste quality.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the taste quality and nutritional values of citrus peel extract without compromising its beneficial properties like antioxidant activity.

Embodiment 1

[0052] Take by weighing 1 kilogram of Leling Jinsixiaozao respectively, then clean the dust, mud, microorganisms and other impurities on the surface of the red jujube raw material with clear water that meets the drinking water standard, to ensure the hygienic requirements of the process; Add 2.4 times the quality of pure water, pre-boil at 75°C for 1 hour; beat. Add 1 times the mass of purified water for cooling. The jujube juice is prepared at a concentration of 15% (mass / volume). Enzymolysis starts at about 40°C; use compound cellulase system A and pectinase powder for enzymolysis, the addition amount is 5000U / kg dry jujube respectively; fully stir the enzymolysis at 45°C for 5 hours, pass through 5 Mesh, 10 mesh, 20 mesh, 60 mesh sieve (without mechanical pressure), fully separate jujube skin and jujube core from jujube juice. The sieved jujube juice is sent to a centrifuge for separation and clarification, and the clarified jujube juice is obtained under the centrifugal ...

Embodiment 2

[0059] A preparation process for jujube clear juice containing high water-soluble dietary fiber and red jujube concentrated clear juice comprises the following steps:

[0060] (1) Selection and cleaning:

[0061] Select 1 kg of bright-colored Leling Jinsixiaozao dried dates, without mildew and deterioration and other miscellaneous fruits; then use clean water that meets the drinking water standard to clean the dust, mud, microorganisms and other substances on the surface of the raw materials of the red dates Impurities to ensure the hygienic requirements of the process.

[0062] (2) Precooking at medium temperature, pitting, beating, peeling:

[0063] Add 2.4 times the weight of pure water to the dried jujube, pre-cook at 60-80°C for 0.25 hour; use a beater to preliminarily break the jujube, remove the core, further beat and peel the jujube.

[0064] (3) Initial enzymatic hydrolysis: add 0.5 times the mass of pure water to cool, add 1000 U of pectinase per kilogram of dried ...

Embodiment 3

[0094] A preparation process for jujube clear juice containing high water-soluble dietary fiber and red jujube concentrated clear juice comprises the following steps:

[0095] (1) Selection and cleaning:

[0096] Select 1 kg of brightly colored jujubes from Jiaxian County in northern Shaanxi, without mildew and deterioration and other miscellaneous fruits; Impurities to ensure the hygienic requirements of the process.

[0097] (2) Precooking at medium temperature, pitting, beating, peeling:

[0098] Add 1 to 2 times the weight of pure water to the fresh jujube, and pre-cook it at 60-80°C for 0.5 hours; use a beater to preliminarily break the jujube, remove the core, further beat and peel the jujube.

[0099] (3) Initial enzymatic hydrolysis: add 1 times the mass of pure water to cool, add 5000 U of pectinase per kilogram of fresh jujube, and use pectinase to carry out enzymatic hydrolysis at 50°C for 2 hours.

Abstract

The invention discloses a preparation technology of red jujube juice or concentrated clear red jujube juice with high water-soluble dietary fiber content. The preparation technology comprises the following steps: selecting and cleaning red jujubes, precooking at medium temperature, removing jujube pits, pulping and removing peel; after that, carrying out primary enzymolysis and secondary enzymolysis, decoloring, filtering and carrying out enzyme inactivation; finally, sterilizing and packaging to obtain the red jujube juice or concentrated clear red jujube juice with the high water-soluble dietary fiber content, wherein in the primary enzymolysis, pectinase is used for carrying out the enzymolysis for 1-3h at the temperature of 40-55 DEG C; in the secondary enzymolysis, a complex cellulase system and the pectinase are used for carrying out the secondary enzymolysis for 1-6h at the temperature of 40-55DEG C, and the complex cellulase system is prepared from endoglucanase, exoglucanase and beta-glucosidase. The preparation technology greatly improves the content of water-soluble dietary fiber and extracts the components with physiological activity in the red jujubes to the utmost extent while guaranteeing the pure taste of the red jujube juice.
