Description
Technical field
The invention belongs to water extractive technique field, the high temperature dipping that relates in particular to a kind of jujube juice extractsMethod.
Background technology
Along with the raising of people's living standard, people are not only satisfied with mouthfeel taste in dietNeed, and more and more focus on the nutrition and health care of diet, effect that diseases prevention is healthy and strong. Red date belongs to pure naturalFood, taste sweet warm in nature, return taste warp, have the function of tonifying middle-Jiao and Qi, nourishing blood and tranquilization, the mitigation property of medicine; AndModern pharmacology finds, red date contain protein, fat, carbohydrate, organic acid, vitamin A,The abundant nutritions such as vitamin C, micro-calcium, amino acid.
Normal edible red date, can improve body immunity, and can inhibition cancer cell: pharmacological research is found, redJujube can promote leukocytic generation, reduces serum cholesterol, improves seralbumin, and protection liver is redIn jujube, also contain inhibition cancer cell, the material that even can make cancer cell transform to normal cell. Often edibleThe people of fresh jujube seldom suffers from gall stone, and this is because of abundant vitamin C in fresh jujube, makes unnecessary courage in bodySterol changes bile acid into, little cholesterol, lithogenous probability also just reduces thereupon. In jujube, be rich inCalcium and iron, they to preventing and treating osteoporosis, postpartum anemia plays an important role, the elderly's climacteric often canOsteoporosis, easily there is anaemia in teenager and the women on the peak of growing, and date is to their meetingHave very good dietary function, its effect normally medicine can not be compared, and eating former jujube has manyInconvenience, although there is the multiple jujube juice taking red date as primary raw material on market, existing extraction of the juice technology does not haveWell keep fruit volatile material. Cause taste and the mouthfeel of pure jujube juice not good, have to modulateRear listing.
Summary of the invention
For solving the deficiencies in the prior art, the invention provides a kind of jujube juice high temperature dipping extraction method. ShouldMethod is by means of relatively convergence type of the one extraction of the juice technology of protecting the special impregnating autoclave of alternating temperature, can greatly reduceThe escape of fruit volatile material, has ensured the original color, smell and taste of product.
A high temperature dipping extraction method for jujube juice, comprises the following steps:
1) jujube is cleaned, is dried;
2) clean, dry jujube being mixed with water and be placed in impregnating autoclave and sealing, is 65～85 DEG C in temperatureUnder condition, be incubated 12～20 hours, lower the temperature afterwards 2～6 hours to room temperature, after filtration, soaked for the first timeJujube after the jujube juice that stain is extracted and for the first time extraction of the juice, wherein: weight ratio when described jujube mixes with water is 1:1.5～1:4；
3) by through step 2) jujube after the extraction of the juice for the first time that obtains mixes with water and is placed in impregnating autoclave and closeEnvelope, temperature is to be incubated 12～20 hours under 70～90 DEG C of conditions, lowers the temperature afterwards 2～6 hours to room temperature,After filtration, flooded for the second time the jujube juice of extraction and the jujube after extraction of the juice for the second time, wherein: for the first time describedWeight ratio when jujube after extraction of the juice mixes with water is 1:1～1:4;
4) by through step 3) jujube after the extraction of the juice for the second time that obtains mixes with water and is placed in impregnating autoclave and closeEnvelope, temperature is to be incubated 12～20 hours under 70～90 DEG C of conditions, lowers the temperature afterwards 2～6 hours to room temperature,After filtration, flooded for the third time the jujube juice of extraction and the jujube after extraction of the juice for the third time, wherein: for the second time describedWeight ratio when jujube after extraction of the juice mixes with water is 1:1～1:4;
5) by described for the first time dipping extract jujube juice, described for the second time dipping extract jujube juice, described inThe jujube juice that dipping extracts for the third time mixes according to volume ratio 1:1:1～1:2:2, obtains repeatedly to flood to extract to mixJujube juice.
The described repeatedly dipping that the high temperature dipping extraction method of jujube juice provided by the present invention prepares extractsMixing jujube juice, there are the exclusive color, smell and taste of pure natural jujube juice, its soluble solid content is 10～12%, ph value is 6～7, and its solid content of jujube juice that conventional method raises is generally 4～5% left sidesThe right side, even if solid content reaches 10%, but most of escape of volatile material, color, smell and tasteDo not reach this law income effect, have to add other material allotments.
Described repeatedly dipping extracts and mixes jujube juice, process tinning or pack, sealing, pasteurize, coldBut, packaging, both finished product jujube juice. This jujube juice processing all processes in do not add other other anyMaterial, only contains original nutrition in red date, therefore its mouthfeel is micro-sweet, and color and luster nature, good taste,Really embody the exclusive local flavor of pure natural jujube juice. The number of times of repeated impregnations extraction of the juice can according to circumstances be fittedWhen increasing or reducing.

(1) extraction of the juice: open cover 2, the sieve bucket 11 that fixes circular lower cover 14 is placed in to impregnating autoclaveIn, the rotating semicircle upper cover of the upper cover 13 of spin-up circle, drops into and washes down not without disease and pestThe pure natural red date of classification arrives sieve bucket 11 in right amount, and fixing circular upper cover 13, is adding water to can body 1In, taking the ratio of jujube and water as 1:2, add 85 DEG C of pure water, add a cover, snap close, totally-enclosed, openOpen steam valve, steam enters can body bottom by steam inlet 7, in conjunction with the jacketed pan being equipped with, makes temperature in tankDegree remains on 80 DEG C, after 30 minutes, opens the air bleeding valve of blast pipe 4 and the water compensating valve of hutch water device 10,Allow the water of 85 DEG C cover in tank, until water overflows from air bleeding valve, the interior red date of drain tank is heated and gives off simultaneouslyAir; Close air bleeding valve, be incubated cooling after 20 hours, steam off valve and water compensating valve, open coldBut the cooling water valve of water inlet 8, allows in the cooling tube of cold water in the interlayer on tank body top and circulates, 2-4When after hour, in tank, juice reaches 20 DEG C of left and right, stop cooling. Close the cooling water valve of cooling water inlet 8, beatOpen juice output valve and the air bleeding valve of juice opening 5, enter blending tank after jujube juice is filtered by 120#, obtain jujube juiceSolid content is 8.5%. After juice in tank all flows out, close juice output valve, open impregnating autoclave upper cover13, add 90 DEG C of pure water, carry out extraction of the juice 2 times according to above operation, gained jujube juice solid content is11.5%. Carry out extraction of the juice 3 times according to 2 operations, gained jujube juice solid content is 8%. (2) mix and adjustJoin: the jujube juice proposing for 3 times mixes, and can to obtain solid content be 9.5% pure natural jujube juice. (3) tinning,Sealing, pasteurize.
The foregoing is only preferred embodiments of the present invention, in order to limit the present invention, not all at thisWithin bright spirit and principle, any amendment of doing, be equal to replacement, improvement etc., all should be included in thisWithin the protection domain of invention.
