Abstract
The invention provides a processing method of dark grape juice. The method comprises the following steps: cleaning and crushing fresh grapes to prepare grape slurry containing grape skins and seeds, performing microwave radiation treatment in a microwave field, promoting components such as polyphenols and the like in the grape skins and seeds to rapidly dissolve into the grape juice, and performing subsequent processing such as juice squeezing and the like according to a conventional method. The grape juice prepared by the method has the fragrance of grape fruits, and can reduce the damage and loss of nutritional components and effective components to the highest extent; the method provided by the invention has high efficiency and energy-saving performance, also can effectively kill microorganisms and enzymes, and is easy to achieve industrial production.
Description
Technical field
The present invention relates to a kind of processing method of dark grape juice.
Background technology
Grape is the fruit of whole world cultivated area maximum, and its output also occupies fruits output prostatitis, the world always, occupies important function in national economy and world commerce.Grape is the fruit of Vitaceae fallen leaves bejuco, another name Pu grape, Portugal, Pu Tao, the purple cherry of gift etc.Grape kind is a lot, contains, has most economic worth most with european race (Vitis vinifera) and U.S.'s kind (Vitis labrusca) cultivation.Grape is distributed in China various places, and the main place of production is the provinces and regions such as Xinjiang, Hebei, Shandong, Shanxi, Liaoning, Gansu, Henan, Anhui, Ningxia.Grape has very high nutritive value, except containing abundant sugar, acid and multivitamin, also contains the functional nutrient compositions such as resveratrol, OPC, tannin, natural colouring matter.In whole world grape total output, approximately have at present 85% for wine brewing, 12% for eating raw, and 5% for making raisins, very little for the manufacture of the grape material proportion of grape juice beverage etc.
According to surveying and determination, grape berry (grape juice) is except moisture content, also containing have an appointment 15g/100g carbohydrate (being mainly glucose, fructose and pentose), various organic acid (malic acid, tartaric acid and a small amount of citric acid, butanedioic acid, gallic acid, oxalic acid, salicylic acid etc.) and mineral matter, and various vitamin, amino acid, protein, carbohydrate, crude fibre, calcium, phosphorus, iron, carrotene, thiamine, riboflavin, niacin, ascorbic acid, lecithin etc.
Summary of the invention
The object of the invention is to provide the processing method before a kind of grape juice processing, the method by new fresh grape clean, fragmentation makes the grape slurries containing Grape Skin, seed, send into and in microwave field, carry out microwave radiation processing, in promotion Grape Skin seed, polyphenols dissolves in grape juice, the following process such as squeeze the juice according to a conventional method again, can produce a kind of grape juice product that is rich in the functional components such as Polyphenols.The method can promote that in Grape Skin, seed, the functional component such as polyphenols dissolves in rapidly in grape juice effectively, because microwave treatment temperature is low, the time is short, avoid the impact of long-time high-temperature process on grape juice quality, can keep well the original color and luster of grape juice, local flavor, at utmost reduce the failure loss of nutritional labeling and functional component, it is high, energy-conservation that described method has efficiency, and effectively killing microorganisms and enzyme of while, is easy to realize suitability for industrialized production.
The processing method of a kind of dark grape juice of the present invention, follows these steps to carry out:
A, to select the red grape of fresh dark color be raw material, soaks, cleans 1-5min under supersonic oscillations in water, sprays cleaning with clear water, drains moisture;
B, grape after step a being cleaned with grape stem removing crusher carry out destemming and break process, make the grape slurries containing Grape Skin, seed, broken time, add the antioxidant of 0.01-0.5% to protect look;
C, step b grape slurries are sent in vacuum receiver, under 10-100kPa, degassed 10-30min stirs in degassed, deviates from the gas in fruit juice;
D, step c grape slurry is sent in microwave field and carried out microwave treatment, microwave power 0.5-50kw, processing time 10-600s, controls temperature≤50 DEG C;
E, by steps d grape slurry through routine squeeze the juice, clarify, the subsequent treatment such as filtration, filling, sterilization can obtain lovely luster and be rich in the original grape juice product of polyphenol components.
Antioxidant described in step b is ascorbic acid, sodium ascorbate, arabo-ascorbic acid or sodium isoascorbate.
Step c agitator speed is 30-180r/min.
In steps d microwave treatment, grape slurry is sent in microwave treatment tank, carry out microwave treatment and stir simultaneously, or by carrier pipe, grape slurries are sent in microwave field, make grape slurries in carrier pipe, accept microwave treatment, the material of carrier pipe is that microwave energy is absorbed to very little glass, plastics or pottery.
