Description

The preparation method of a kind of raspberry seed extract and raspberry polymerization fruit juice and application
Technical field
The present invention relates to the preparation method of a Plant Extracts and plant juices beverage, particularly the preparation method of a kind of raspberry seed extract and raspberry polymerization fruit juice.
Background technology
Raspberry is divided into the red certain kind of berries, blackberry, blueberry, the yellow certain kind of berries, it is the economic fruit tree plant of berries of rose family rubus, the Origin of cultivation of this Plants is in Europe, and form industry gradually, there is the history of centuries, current countries in the world start to cultivate raspberry crop all gradually, and to late 1990s, world's raspberry yield has reached more than 35640 ton.Fruit of raspberry is aggregate fruit, is erythrocarpus time ripe.Containing abundant sugar, organic acid, vitamin C, vitamin E, citrin, FA and hematopoiesis compound in raspberry berry, become the medical foods being conducive to diseases prevention, curing the disease, and containing tanning acid (content is up to 1.5-2.0mg/100g fresh fruit) and in a large number natural plants SOD (superoxide dismutase), raspberry ketone, salicylic acids (natural aspirin) etc. in a large number.Wherein raspberry contains abundant Flavonoid substances, flavone compound has multiple beneficial in the physiologically active of health, comprise antioxidation activity, antitumor activity, to the effect of inflammation and immunocyte, regulates fragility and the permeability of capillary, protect cardiovascular and permeability, protection cardiovascular system, on the impact of enzyme system in body, antibiosis and antiviral functions etc.; And raspberry has special curative effect to colon cancer, cervical carcinoma, breast cancer and cancer of pancreas, having skin maintenance, anticancer, anti-ageing, step-down, the effect such as lipopenicillinase and prevention anaemia, enterogastritis, cardiovascular and cerebrovascular disease, is a kind of natural health care with important biomolecule function and nutritive value.
In the industrialization application process of raspberry, the thin succulence of sarcotesta due to raspberry, easily touch brokenly pericarp during harvesting to occur to go rotten, normal temperature is preserved and is generally difficult to reach 24 hours, not storage tolerance and transport, therefore the area of establishing in large scale raspberry, set up processing factory more, ensure that the fresh fruit plucked the same day can process process, so annual harvesting still stays a large amount of raspberry seeds to be underutilized after producing, reduce the enthusiasm of farmers' income and peasant planting raspberry, also waste natural resources and be included in the nutritional labeling in raspberry seed simultaneously.Therefore, carry out further deeply research and development to the fruit juice product of raspberry, to environmental protect, the added value improving fruit juice product is significant.
Patent of invention CN03134577.8 adopts and once adds RC212 active dry yeast list bacterium zymotechnique, its acid adjustment simultaneously utilizes D380 ion-exchange resin acid reduction method after fermentation, and result fully can not keep distinctive nutritional labeling and biological function in red raspberry fruits.Patent of invention CN102018252A discloses a kind of red raspberry beverage, mass fraction in product shared by each raw material is: raspberry pulp is 15% ~ 45%, table sugar is 5% ~ 10%, food acids is 0.05% ~ 0.2%, gellan gum is 0.01% ~ 0.02%, pectin is 0.02% ~ 0.04%, and essence is the water of 0.1% ~ 0.5% and surplus; The product that this invention is is main material with raspberry pulp, farthest remain red raspberry fruits pulp fraction, in product, dietary fiber content significantly improves, and its local flavor is more mellow.Patent of invention CN101375705 discloses a kind of raspberry health-care beverage and preparation method thereof.Concrete count 1.00-2.00 part by weight raspberry, the white granulated sugar of 0.25-0.5 part, the honey of 0.20-0.25 part, the date of 0.10-0.20 part, the matrimony vine of 0.10-0.20 part and 1.20-1.50 part water.The present invention obtains drink sour and sweet palatability, aromatic flavour, unique flavor.Its preparation technology is simple, easy to operate, efficiently convenient.And drink of the present invention contains abundant natural polyphenol class material and SOD enzyme isoreactivity composition.
Above prior art is all unresolved to be made full use of raspberry seed and increases the problem of natural nutrient component in raspberry fruit juice.
