Description
Technical field
The present invention relates to a kind of fruit antistaling agent, particularly relate to a kind of antistaling agent for litchi based on Chinese herbal medicine and preparation method thereof.
Background technology
Lichee originates in China, is the good fruit in the Chinese south of the Five Ridges, and its color is all beautiful, has won fame both at home and abroad, and has the title of " fruit king ", is distributed in Guangdong, Guangxi, Fujian, Sichuan, Taiwan and Yunnan.After but lichee is adopted very easily brown stain rot, among the people have: " its food lichee one day and look becomes, two days and fragrant the change, three days and flavor becomes, four, multicolored fragrance goes " saying.Because lichee contained humidity, sugar are higher, the physiological property such as pericarp is rich in tannin, and polyphenol oxidase and peroxidase activity are very strong is midsummer when adding maturation, and moisture evaporation, germ easily grow, so very easily brown stain is corrupt, freshness date is extremely short.The perishable characteristics of lichee have had a strong impact on finding a good sale in of this fruit and shelf life.China is the maximum country of plantation lichee at present, and according to statistics, the annual loss that causes because rotting of lichee accounts for more than 20% of total output, causes huge economic loss.As seen the preservation technique of lichee seems particularly important.
The antistaling agent that is used at present lichee mainly contains chemical preservative and bio-preservative, chemical preservative comprises antiseptic drug commonly used such as benomyl, TBZ, sterilization prestige, and the organic acids such as sulphuring or citric acid are processed, the method is fresh-keeping and bactericidal effect is better, but have chemical residual, safety coefficient is not high, and people's health is threatened.The material source of bio-preservative comprises natural animal-plant extract or its compound in nature, and especially the biological film-coating method was constantly developed in recent years.The method be with natural macromolecular materials such as polysaccharide, protein and greases as smearing material, and be coated in fruit surface with the state of the aqueous solution or emulsion, form film after it is dry.This layer film can prevent that moisture evaporation, the physiological biochemical reaction of regulating plant and delayed fruit are old and feeble and corrupt, has again the effects such as the bacterium of preventing infringement.The advantages such as that the natural biological coating antistaling agent has is natural, environmental protection, good refreshing effect, that is that all right is ripe due to its technology, and the material requested cost is higher, is unfavorable for promoting.
Summary of the invention
For above-mentioned deficiency, technical problem to be solved by this invention is to provide a kind of environmental protection of adopting the Chinese herbal medicine material to make, without chemical agent, and production cost is low, good refreshing effect, antistaling agent for litchi that fresh keeping time is long and preparation method thereof.
For addressing the above problem, the present invention is achieved through the following technical solutions:
A kind of antistaling agent for litchi based on Chinese herbal medicine is comprised of the material of following percentage by weight:
Galingal 8～12%, the tuber of stemona 2～8%, eucalyptus robusta 5～10%, kiss-me 3～8%, honeysuckle 5～10%, berberine 8～12%, the Radix Astragali 2～5%, garlic 2～8%, konjaku flour 3～10%, agar 1～5%, lecithin 1～5%, starch 10～15%, water 50～80%.
In such scheme, preferably, described starch is one or both in cornstarch, starch from sweet potato.
The preparation method of above-mentioned a kind of antistaling agent for litchi based on Chinese herbal medicine comprises the following steps:
(1) preparation of extracts of Chinese herbal medicine: first water is mixed by 4:1 with ethanol, with this as extract; Again above-mentioned galingal, the tuber of stemona, eucalyptus robusta, kiss-me, honeysuckle, berberine, the Radix Astragali, 8 kinds of Chinese herbal medicines of garlic are added in the container of heat resisting and pressure resisting, and add the ethanol extract for preparing, its amount to be 5～10 times of Chinese herbal medicine weight; Then extract 10～30min at 20～100MPa and 200～350 ℃ of temperature, then step-down is cooled to normal temperature and pressure, isolates the medium-height grass the effective elements of the medicine, discard the dregs of a decoction, namely get the primary raw material of described antistaling agent;
(2) gelatinized starch preparation: cornstarch or starch from sweet potato are carried out gelatinization with Pasting machine at the temperature of 98～180 ℃, crushed after being dried namely gets gelatinized starch, in order to the crosslinked strengthening agent of antistaling agent;
(3) antistaling agent preparation: gelatinized starch, extracts of Chinese herbal medicine, konjaku flour, lecithin, agar are added in another container, and uniform stirring, mixing 15～30min namely get described antistaling agent finished product.
The fresh-keeping mechanism of the present invention is:
Galingal: belong to zingiberaceous plant.Warm in nature, bitter is hot.The function promoting the circulation of qi, invigorate blood circulation, pain relieving.
The tuber of stemona: also claim Radix stemonae japonicae, perennial herb.The underground spindle shape meat piece root that clusters.On traditional Chinese medicine with piece root people medicine.Slightly warm in nature, bitter but sweet flavor.The cough-relieving of function temperature lung, desinsection.One of this agent primary raw material is as pesticide.
Eucalyptus robusta: the little suffering of property, mildly bitter flavor, flat.Cure mainly dispelling wind analgesic, inhibiting bacteria and diminishing inflammation, anticorrosion antipruritic.One of this agent primary raw material is as bactericide.
