Abstract
The invention relates to a method for extracting a biological preservative from traditional Chinese medicines. The method comprises the following operating steps: (1) screening the traditional Chinese medicines, and removing foreign matters, such as soil and tree leaves; (2) crushing the traditional Chinese medicines until the particle size of the crushed traditional Chinese medicines is 50-100 meshes; (3) putting the crushed traditional Chinese medicines into a pot, adding water into the pot in accordance with that the material/liquid ratio is 1: (2-4), soaking for 2-4 hours, heating to boil with strong fire, decocting for 30-60 minutes with soft fire, filtrating, collecting the filtrate, and preserving the filtrate in a refrigerator with the temperature of 2-4 DEG C; (4) adding water into residue in accordance with that the material/liquid ratio is 1: (1-2), soaking for 2-4 hours, decocting for 30-60 minutes, filtrating, combining the filtrates, and preserving the combined filtrate in the refrigerator with the temperature of 2-4 DEG C. The invention further provides application of the biological preservative extracted from the traditional Chinese medicines. The biological preservative, extracted from the traditional Chinese medicines which serve as raw materials, disclosed by the invention is used for preserving fruits, is safe, non-toxic and nuisance-free and can be used for keeping the fruits fresh instead of chemical bactericides and preservatives, and the problems of environmental pollution, food safety and the like caused by the chemical bactericides are avoided.
Description
Technical field
The present invention relates to biological preservation field, specifically from method and the application thereof of traditional Chinese medicine extraction bio-preservative.
Background technology
Chinese herbal medicine is the exclusive natural plant resource of China, and resource recoverable amount is large, and cheap, many research shows, many Chinese herbal medicines have spectrum antibacterial effect.Same chemical preservative, antiseptic are compared, and the antipathogenic composition contained by Chinese herbal medicine has and not easily produces that drug resistance, toxic and side effect are little, security advantages of higher.
Fruit, because its moisture is high, delicious flavour; rich in nutritive value, but the respiratory intensity of general berry fruits is large, and protective tissue is poor; preservation and freshness is more difficult, and preservation term and shelf life are all shorter, can bring great loss like this for orchard worker and consumer.And the preservation method of berries fruit conventional at present mainly adopts chemical bactericide, and a large amount of uses of chemical bactericide, pathogenic microorganism can be caused to produce drug resistance, and environmental pollution; In addition, because cleaning is more difficult, be difficult to thoroughly wash away chemical bactericide, after edible, health hidden danger can be caused.
Summary of the invention
According to above-mentioned weak point, the object of this invention is to provide a kind of method and application thereof of from Chinese medicine, extracting bio-preservative.
For achieving the above object, technical scheme of the present invention is: a kind of method extracting bio-preservative from Chinese medicine, and its operating procedure is as follows: Chinese medicine is cleaned by (1), foreign material such as removing earth, leaf etc.; (2) traditional Chinese medicine powder is broken to 50-100 order; (3) Chinese medicine of flour being put into pot, is that the ratio of 1:2-4 adds with solid-liquid ratio, soaks 2-4h, and strong fire is heated to boiling, then with 30-60min at a simmer, filters, and collects filtrate, is placed in 2-4 DEG C of Refrigerator store; (4) residue is that the ratio of 1:1-2 adds water with solid-liquid ratio, soaks 2-4h, then decocts 30-60min, and filter, merging filtrate, is placed in 2-4 DEG C of Refrigerator store.
Preferably: described Chinese medicine is one or more in dandelion, moutan bark, Herba portulacae, cordate houttuynia.
The present invention also provides a kind of application of extracting bio-preservative from Chinese medicine, and fruit is soaked 3-5min in the solution, drop goes out air-dry, then preserves with after PE-PP composite waterproofing membrane, polyethylene film is opened some apertures; Duration of storage is made regular check on, in time the abnormal fruit of cleaning; Fruit storage condition is relative humidity 90-95%, and temperature is 1 ± 0.5 DEG C.
Preferably: described fruit is strawberry, grape, cherry, raspberry, blueberry or cherry tomato.
Beneficial effect of the present invention is: the present invention is that raw material extraction bio-preservative carries out fresh-keeping to fruit with Chinese medicine, safety.Nontoxic, nuisanceless, fresh-keeping for fruit of chemical bactericide, anticorrisive agent can be replaced, avoid the problem such as pollution, food security of chemical bactericide to environment.
