Description

A kind of preparation method of white fungus red jujube can

technical field:

The present invention relates to a kind of food processing technology, particularly relate to a kind of preparation method of white fungus red jujube can.

project background:

Red date is also referred to as date, Chinese date etc., contains rich in protein, fat, sugar part, carrotene, Cobastab, C, P and phosphorus, calcium, iron etc., has the laudatory title of vitamin pill, has stronger love, the anti-allergic effects of pressing down.Red date contains CAMP, can strengthen muscular strength, eliminates fatigue, hemangiectasis, increase myocardial contractive power, improve myocardial nutrition, and prevention and cure of cardiovascular disease is had to good action.Red date can also can qi-restoratives benefit gas, nourishing blood and tranquilization, strengthening the spleen and stomach etc., be the good health products of patient such as weakness of the spleen and the stomach, insufficiency of vital energy and blood, lassitude, insomnia.The diseases such as acute, chronic hepatitis, cirrhosis, anaemia are had to good efficacy simultaneously.Red date is a kind of good fruit thus, and price neither be very expensive, can be used as snacks and eat, and is of value to physically and mentally healthy.

Red date fresh goods is storage tolerance not, is used for processing jujube dry, and red date can be realized to the deep processing and utilization to red date for processing red jujube can, increases economic efficiency.

summary of the invention:

The preparation method that the object of this invention is to provide a kind of white fungus red jujube can with health role, realizes the deep processing comprehensive utilization of red date raw material.

The present invention solves the technical scheme that its technical problem takes:

A preparation method for white fungus red jujube can, is characterized in that: adopt raw material to select → remove the peel → stoning → precook → join the technological process of soup → sealed cans → sterilization → cooling → finished product with tinning → exhaust after white fungus, syrup → sealing → sterilization → cooling → check → finished product raw material sorting → cleaning → classification → tinning; Concrete operation step is:

1. select raw material to select to select that meat is thick, skin is thin, core is little, approach complete red crisp dates, reject disease and pest, go rotten, damage and too small fruit, and size classification;

2. 7%-9% sodium hydroxide solution is prepared in peeling, boil, jujube is put into and maintained 2-3 minute, become dark red to fruit colour, with bamboo strainer, touch when table pik comes off and pull out at once, cold water flush, and the de-fructus corni of sieve, the residue alkali lye on jujube fruit surface to be rinsed well, the peeling time is not long, otherwise can make pulp corrosion and brown stain, affect quality of finished;

3. stoning is with after stoner stoning, and clear water rinsing is clean;

4. precook and jujube is really put into rare citric acid solution of 0.1%-0.15%, be heated to 95-98 ℃, boil 3-5 minute, to the tissue shape that is translucent, tough and when not rotten, cooling rapidly, tinning fast;

5. white fungus is processed and is gone the base of a fruit to clean in white fungus, with cold water soak 2-3 hour, then boils 15 minutes with 0.1% the little fire of citric acid solution, it is risen and send out;

6. the syrup 180-200 gram of 240-255 gram of the glass bottle jujube of 500 milliliters of tinnings fruit, white fungus 32-36 gram, 25%-30%, in liquid glucose, the content of citric acid is 0.15%-0.20%;

7. exhaust, vacuum 50-55 MPa vacuum seamer sealing for sealing keep 12-15 minute after sealing in 90 ℃ of fumers, when tank central temperature reaches more than 70 ℃, seal rapidly;

8. sterilization immediately after sterilization, coolant seal, bactericidal formula is 6 '-12 '/100 ℃, and segmentation is cooled to below 35 ℃, wipes tank, and through being up to the standards, warehouse-in, is finished product.

Quality requirement: pulp is yellow or light yellow, color and luster uniformity, syrup is more transparent, and white fungus is pure white, and fruit shape is complete, soft or hard appropriateness, pulp accounts for net weight 45-50%, and during can opening, syrup concentration is 20%-25%.

Beneficial effect: product nutritious tonifying of the present invention, there is good health-care effect, it is simple to operate, is convenient to implement, and economic benefit is good, can realize the comprehensive utilization to red date raw material.

the specific embodiment:

Embodiment 1
