Abstract
The invention relates to a preparation process of wild jujube juice, which includes steps of separating pericarp, sarcocarp and seed of wild jujube by a gravity suspension method, preserving pericarp and sarcocarp of wild jujube, grinding the pericarp and sarcocarp of wild jujube into wild jujube slurry by a colloid mill, adjusting water content of the wild jujube slurry to 70-90%, mixing the wild jujube slurry and a extract aid ethanol, uniformly stirring, standing, filtering in vacuum, carrying out dehydration and removal of impurities repeatedly, extracting processed wild jujube slurry by using ethyl acetate to obtain filtrate, and concentrating the filtrate in vacuum. The invention has advantages of simple process, easy operation, rich nutrition, pure and good taste, and high production efficiency, is favourable to human body health, and is especially suitable for modern industrial production.
Description
Technical field
The invention belongs to food technology field, particularly relate to a kind of preparation technology of Wild jujube juice.
Background technology
Wild jujube is spontaneous self-produced hill product, grown by the life elite, and it contains multivitamin, and to human body beneficial's trace element, is a kind of rare natural prodcuts.Exploitation to Wild jujube mainly is on wild jujube skin and flesh and beverage at present, mainly be that Wild Jujube Juice and honey, white granulated sugar mixed preparing are added stabilizing agent again on beverage, its shortcoming is: 1. the technology of processing Wild Jujube Juice is complicated, can not make full use of the nutritional labeling of wild jujube, and in leaching process, lose a large amount of nutritional labelings; 2. the extraction process production efficiency of existing Wild Jujube Juice is low, is not suitable for suitability for industrialized production.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art part, provide that a kind of technology is simple, production efficiency is high and can guarantee the Wild jujube juice preparation technology of nutritional labeling.
The technical scheme that the present invention takes is:
A kind of preparation technology of Wild jujube juice, its preparation technology's step is:
(1). the skin seed separates: adopt the gravity suspension method to separate skin and flesh, the seed of wild jujube, retain wild jujube skin and flesh;
(2). pulverize wild jujube skin and flesh: grind with colloid mill the Pericarpium Ziziphi Spinosae digested tankage is broken into the wild jujube slurry, the water content of regulating the wild jujube slurry is 70～90%;
(3). the preliminary treatment of wild jujube slurry: the wild jujube slurry is mixed with extraction aid, leave standstill after stirring, suction filtration carries out dehydrating and removing impurities repeatedly several times;
(4). organic solvent extracts: utilize organic solvent that the wild jujube slurry of having handled is extracted, extract 2～4 times, obtain filtrate;
(5). be condensed into finished product: filtrate is carried out vacuum concentrate, promptly obtain Wild Jujube Juice.
And described extraction aid is an ethanol.
And the organic solvent in the described organic solvent extraction step is ester, ketone, alcohols solvent, ethyl acetate; The wild jujube slurry is 1:1～1:15 with the w/v of organic solvent, is preferably 1:2～1:10; Extract temperature and be 30 ℃≤T≤60 ℃; Extraction time is 1h≤t≤3h.
And describedly filtrate is carried out the thickening temperature T that vacuum concentrates be: 30 ℃≤T≤60 ℃, concentration time t is: 1h≤t≤4h.
Advantage of the present invention and good effect are:
1. to process the technology of Wild Jujube Juice simple in the present invention, can fully keep the nutritional labeling of wild jujube, can not cause the disappearance of nutritional labeling;
2. technology of the present invention is simple, easy operating, and the Wild Jujube Juice of being made is nutritious, pure taste, mouthfeel is better, helps the healthy of people, and production efficiency is higher, is particularly suitable for modernization industry and produces.
The specific embodiment
Below in conjunction with embodiment, the present invention is further described; Following embodiment is illustrative, is not determinate, can not limit protection scope of the present invention with following embodiment.
A kind of its preparation technology of Wild jujube juice, its preparation technology's step is:
(1). the skin seed separates: adopt the gravity suspension method to separate skin and flesh, the seed of wild jujube, retain wild jujube skin and flesh;
(2). pulverize wild jujube skin and flesh: grind with colloid mill the Pericarpium Ziziphi Spinosae digested tankage is broken into the wild jujube slurry, the water content of regulating the wild jujube slurry is 70～90%;
(3). the preliminary treatment of wild jujube slurry: the wild jujube slurry is mixed with extraction aid ethanol, leave standstill after stirring, suction filtration carries out dehydrating and removing impurities repeatedly several times, and wherein the wild jujube slurry is 1:1～1:10 with the w/v of ethanol, is preferably 1:2～1:5; The extraction aid concentration of ethanol is preferred 75～95%, number of processes 1～3 time; Reaction time 10～the 50min of Ethanol Treatment wild jujube slurry, course of reaction at room temperature lucifuge is carried out;
