Background technology
Along with conservation of wild plant consciousness continually strengthen and plant expanding economy, the wild and plantation Kiwifruit resource of China is expanded increase gradually, its utilization of resources also more and more is subjected to the extensive concern of society.Industry studies show that Kiwifruit is not only nutritious, and contains trace elements such as multiple amino acids, VITAMIN and copper, calcium, magnesium, manganese, potassium, lithium, selenium, iron, phosphorus, body function, the metabolism of human body is had the medicinal health care function of uniqueness.But, because fresh-keeping factor has greatly limited the utilization of Kiwifruit resource, cause a large amount of wastes of addling, bring bigger financial loss to the orchard worker, also restricted development and the utilization of Kiwifruit renewable resource simultaneously.In the recent period, society begins to seek the Kiwifruit brewing technology, but because this utilizes approach still to be in the exploratory stage at initial stage, and technology maturity is lower, causes industrialization speed slow, the containment wasting of resources is weak.The major defect of the Kiwifruit brewing technology existence that occurs at present:
1) usually to heating after the Kiwifruit fragmentation to squeezing the juice more than 80 ℃, can make the carambola juice color become brown like this, high temperature makes the nutrition of Kiwifruit itself be damaged again, and great changes will take place for mouthfeel, and fruit juice quality before not entering fermentation is degenerated;
2) producing the more traditional method of Yangtao wine is the belt leather fermentation, treat skin slag come-up after, separate wine liquid.This method one is the squeezing difficulty, the 2nd, owing to the pericarp long soaking time, make the color burn of wine, and tannin content raises, and total acid and volatile acid raise, and liquor output rate is low;
3) all kinds of chemical synthesis preparations such as additive, sanitas are arranged more in the brewing process, not only destroy the nutritive ingredient in the Kiwifruit easily, and to drinking person generation toxic side effect in various degree, be unfavorable for HUMAN HEALTH;
4) present brewing technique mostly is earlier Kiwifruit to be squeezed separation, brewage with fruit juice, and the main component pectin in the pericarp contains 18 seed amino acids, Vc and various trace element, has very high nutritive value, be undoubtedly a kind of very big wasting of resources with pomace is then discarded in vain, and influence the yield of liquor of Kiwifruit raw material greatly;
5) making method and device structure complexity, the production cost height.
