Description

A kind of Chinese herbal medicine antistaling agent and preparation method thereof for winter jujube
Technical field
The present invention relates to Chinese herbal medicine antistaling agent and preparation method thereof, is a kind of special Chinese herbal medicine antistaling agent for fresh-keeping of dong jujube, belongs to food additives field.
Background technology
In food industry, the anti-corrosive fresh-keeping of food is a major issue urgently to be resolved hurrily all the time.According to estimates, the whole world has 10%~20% food to be lost in various corruption every year.Along with the pay attention to day by day of the mankind to foodsafety and environmental issue, pollution-free food, organic food are subject to people's favor just gradually, the drawback of traditional chemical antisepsis antistaling agent appears day by day, the wholefood antisepsis antistaling agent of research and development wide spectrum " efficiently " safety, becomes one of focus in current food additives research field.
The rare fruit that Dong Zaoshi China is exclusive, belongs to the late-maturing excellent strain of eating raw.The thin meat of winter fructus corni is crisp, dense sweet micro-acid, and the delicate succulence of pulp, sweet taste is extremely dense, and slightly tart flavour has strong jujube fragrance, and Vitamin C content is up to 300~500mg.100 -1soluble solid content 34~36%, mineral matter and trace element are abundant, and be rich in CAMP (cAMP) and cyclic guanosine monophosphate (cGMP), not only there is the multiple physiological regulation functions such as the fragility of blood vessels of preventing increase and atherosclerosis, and have good antitumaous effect, and be the most high-grade kind of eating raw in current jujube, favored by market.In recent years, supply falls short of demand in domestic and international market for winter jujube, and its economic benefit is several times even tens times of other crops.
Due to winter jujube itself intrinsic biology and physiology characteristic, institutional framework is special, and post-harvest physiology changes complicated, and storage period is only 4~5 d at normal temperatures, and mechanical freezer also can only be preserved 50~60 d, and after storage, good fruit rate is low, and commercialized degree is not high.Winter jujube because of its water content high, to the O in environment 2and CO 2responsive especially, adopt rear 3~5 d that naturally place and lose fresh and crisp shape, can find dehydration elephant skin, pulp softening, brown stain, also with dense vinosity and mildew and rot phenomenon, nutritional labeling is destroyed simultaneously, particularly Vc content reduces greatly, has greatly shortened the selling period of jujube, for eating and process dual-purpose jujube raw, seriously restrict processing and the development of jujube, become the bottleneck of winter jujube plant production development.
Anti-corrosive fresh-keeping material take plant resources as raw material be subject to popular approval and favor without chemistry murder by poisoning, noresidue, the advantage such as have no side effect.Chinese herbal medicine extract energy fruit and vegetable preservation, principle is that the active ingredient in Chinese herbal medicine can suppress the microbial activities of fruit and vegetable surfaces, reduces the vigor of enzyme in fruits and vegetables, so can weaken the impact of microbial activities on fruits and vegetables, reduce the physiological activity intensity of fruits and vegetables, thereby play fresh-keeping object.
Summary of the invention
The object of the present invention is to provide a kind of winter jujube that is suitable for to eat the Chinese herbal medicine antistaling agent that the emerging green safety of insurance has no side effect raw, be specially adapted to winter jujube and pluck the Preservation Treatment of rear market selling period, extend the shelf time of winter jujube product, the present invention includes concrete composition and the preparation method of winter jujube Chinese herbal medicine antistaling agent.
Winter jujube of the present invention by chief component and the preparation scheme of Chinese herbal medicine antistaling agent is:
A kind of winter jujube Chinese herbal medicine antistaling agent, mainly formed by extracts of Chinese herbal medicine, film forming agent and secondary solvent, wherein each component proportion is respectively: extracts of Chinese herbal medicine accounts for 10%~20% of antistaling agent cumulative volume, secondary solvent accounts for 80%~90% of antistaling agent cumulative volume, the use amount of film forming agent is rational film forming addition, the quality of film forming agent be generally extracts of Chinese herbal medicine and secondary solvent quality and 2%~5%.
The invention provides a kind of winter jujube Chinese herbal medicine antistaling agent, contained extracts of Chinese herbal medicine is the mixed liquor by following Chinese herbal medicine kind extract: galingal, cloves, kuh-seng, Radix Glycyrrhizae, rheum officinale.Controlled being made as of concentration of extracts of Chinese herbal medicine: galingal 20%~40%; Cloves 20%~30%; Kuh-seng 5%~10%; Radix Glycyrrhizae 10%~20%; Rheum officinale 10%~20%; Its concentration implication is the ratio of Chinese herbal medicine quality to extraction solvent volume, and unit is g/100mL.The solvent extracting for Chinese herbal medicine is pure water, and extracting method is water and ethanol two step extraction methods.
The invention provides a kind of winter jujube Chinese herbal medicine antistaling agent, wherein contained film forming agent can be selected from one or more in starch, konjaku, lecithin, xanthans, dextrin.
The invention provides a kind of winter jujube Chinese herbal medicine antistaling agent, wherein contained secondary solvent is sucrose and the Vc aqueous solution, and sucrose concentration is that 3%~5%, Vc concentration is 1%~5%, its concentration implication is the ratio to extraction solvent volume for sucrose or Vc quality, and unit is g/100mL.
The invention provides a kind of winter jujube Chinese herbal medicine antistaling agent, its preparation method is as follows: select above-mentioned 5 taste Chinese herbal medicines, obtain extracts of Chinese herbal medicine by water and ethanol two step extraction methods; Sucrose and Vc are obtained to secondary solvent by above-mentioned concentration preparation, then add secondary solvent to be made into film forming agent solvent film forming agent component, then extracts of Chinese herbal medicine and film forming agent solution are mixed, stir and make Chinese herbal medicine antistaling agent.
