Description

A kind of processing method of preserved red date

Technical field

The present invention relates to a kind of processing method of preserved fruit, especially relate to a kind of processing method of preserved red date.

Background technology

Red date has another name called date, dry jujube, originate from China, have the plantation history of more than 4,000 year in China, be just listed in since ancient times one of " five fruits " (peach, Lee, plum, apricot, jujube), containing inhibition cancer cell, even cancer cell can be made to the material of normal cell turnover.Often the people of edible fresh jujube seldom suffers from gall stone, this is because vitamin C abundant in fresh jujube, makes cholesterol unnecessary in body change bile acid into.

China herbal medicine books " herbal classic " in be recorded, red-jujube flavor 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; The pharmacology in modern times then finds, red date contains the abundant nutrition such as protein, fat, carbohydrate, organic acid, vitamin A, vitamin C, micro-calcium several amino acids.Red date can improve body immunity, and can inhibition cancer cell: pharmacological research finds, red date can promote leukocytic generation, reduce serum cholesterol, improve seralbumin, protection liver, also containing inhibition cancer cell in red date, cancer cell even can be made to the material of normal cell turnover; Often the people of edible fresh jujube seldom suffers from gall stone, this is because vitamin C abundant in fresh jujube, makes cholesterol unnecessary in body change bile acid into, little cholesterol, lithogenous probability also just reduces thereupon; And be rich in calcium and iron in red date, they to preventing and treating osteoporosis, postpartum anemia plays an important role.Normal food red date can treat in poor health, neurasthenia, incoordination between the spleen and the stomach, indigestion, epersalgia cough, anaemia are become thin, and nourishing the liver preventing cancer function is particularly outstanding, has saying of " solar eclipse three jujubes, at the age of one hundred years old bear one's age well ".

Red date growth cycle is short, can not supply in the four seasons, for processing the comprehensive utilization that preserved red date product can realize red date, improves its economic worth.

Summary of the invention

The object of the invention is to solve red date growth cycle short, the problem that can not supply in the four seasons, provides a kind of processing method of preserved red date.

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

A processing method for preserved red date, is characterized in that: adopt raw material selection, sclerosis, stoning, sugaring, pan boiling, smoke, pack, the processing process of finished product, and concrete operation step and main points are:

A, raw material are selected: select that ninety percent ripe, fresh full, individual pork is thick, local flavor is normal, without going rotten, without disease and pest, the fruit that has no mechanical damage;

B, sclerosis: the red date of select is poured in the sodium metabisulfite solution of 0.15% ~ 0.18% and soak 8 ~ 10 hours;

C, stoning: remove with the core of stoner by red date after leaching sulphur, must not fruit be destroyed during stoning complete, not make pulp crushing;

D, sugaring: the red date of stoning is carried out rinsing, the curing agent that removing is remaining, is then placed on red date in the liquid glucose of concentration 60% and pickles 6 ~ 8 hours;

E, pan boiling: the red date fruit after sugaring is poured in pot together with liquid glucose, and adds appropriate sucrose and malic acid, pan boiling 1 ~ 2 hour, makes sugar concentration reach 70%; Red date pulp good for boiling is poured in cylinder together with liquid glucose and carries out second time sugaring, 4 ~ 5 days time, then fruit is pulled out the clean liquid glucose of drop, room can be entered and smoke;

F, to smoke: drying room temperature keeps 45 ~ 55 DEG C, go out room cooling after smoking 5 ~ 6 hours and be finished product;

G, packaging: the preserved fruit food bag smoked is packed, is finished product.

Beneficial effect: product of the present invention is transparent glossy, sweet and sour taste is neither too hard, nor too soft.Be easy to storage, be convenient for carrying, throughout the year all edibles.Simple to operate, convenient enforcement.Product has taste specific to raw material and local flavor, nutritious, has effect of nourishing beauty treatment, nourishing the liver anti-cancer.

B, sclerosis: the red date of select is poured in the sodium metabisulfite solution of 0.18% ~ 0.24% and soak 12 ~ 16 hours, soak time is unsuitable long, otherwise can cause red date breach;

C, stoning: remove with the core of stoner by red date after leaching sulphur, must not fruit be destroyed during stoning complete, not make pulp crushing;

D, sugaring: the red date of stoning is carried out rinsing, the curing agent that removing is remaining, is then placed on red date in the liquid glucose of concentration 60% and pickles 2 ~ 4 hours;

E, pan boiling: the red date fruit after sugaring is poured in pot together with liquid glucose, and adds appropriate maltose and citric acid, pan boiling 20 ~ 40 minutes, makes sugar concentration reach 65%; Red date pulp good for boiling is poured in cylinder together with liquid glucose and carries out second time sugaring, 4 ~ 6 days time, then fruit is pulled out the clean liquid glucose of drop, room can be entered and smoke;

F, to smoke: drying room temperature keeps 60 ~ 70 DEG C, goes out room, then coat a little jam after smoking 1 ~ 2 hour, cooling is dried and is finished product;

G, packaging: the preserved fruit food bag smoked is packed, is finished product.

The part that the present invention does not relate to prior art that maybe can adopt all same as the prior art is realized.
