Abstract

The invention relates to a method for extracting a biological fresh keeping agent from traditional Chinese medicines. The method comprises the following steps: cleaning Herba Houttuyniae and Weeping Forsythia to remove foreign materials; crushing Herba Houttuyniae and Weeping Forsythia; putting the crushed Herba Houttuyniae and Weeping Forsythia in a pot according to a ratio of 1:1-1:3, adding water according to a solid/liquid ratio of 1:1-3, immersing for 3-4h, heating with intense fire until boiling, decocting with slow fire for 20-30min, filtering, collecting the obtained filtrate, and preserving the filtrate in a 2-4DEG C refrigerator; and adding water to residues according to a solid/liquid ratio of 1:0.5-1, immersing for 1-2h, decocting for 30-60min, filtering, mixing the above obtained filtrates, and preserving the obtained filtrate mixture in the 2-4DEG C refrigerator. The biological fresh keeping agent extracted from Herba Houttuyniae and Weeping Forsythia is safe, nontoxic and nuisanceless in fruit freshness keeping, can replace chemical bactericides and antiseptic to realize fruit freshness keeping, and avoids the problems of environmental pollution and food safety of the chemical bactericides.

Description

The method of bio-preservative and the application in fruit freshness preserving thereof is extracted from Chinese medicine

Technical field

The present invention relates to water field of fruit freshness keeping, a kind ofly specifically from Chinese medicine, extract the method for bio-preservative and the application in fruit freshness preserving thereof.

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 of bio-preservative of extracting from Chinese medicine of safety and Health and the application in fruit freshness preserving thereof.

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:

1, cordate houttuynia, the capsule of weeping forsythia are cleaned, removing foreign material;

2, cordate houttuynia, the capsule of weeping forsythia are pulverized;

3, the cordate houttuynia of flour, the capsule of weeping forsythia being put into pot by weight the ratio for 1:1-1:3, is that the ratio of 1:1-3 adds with solid-liquid ratio, soaks 3-4h, and strong fire is heated to boiling, then with 20-30min at a simmer, filters, and collects filtrate, is placed in 2-4 DEG C of Refrigerator store;

4, residue is that the ratio of 1:0.5-1 adds water with solid-liquid ratio, soaks 1-2h, then decocts 30-60min, and filter, merging filtrate, is placed in 2-4 DEG C of Refrigerator store.

Preferably: described cordate houttuynia, the capsule of weeping forsythia are crushed to 50-100 order;

The present invention also provides the application of extracting bio-preservative from Chinese medicine, and fruit is immersed in 3-5min in the filtrate of step as above extraction, 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, cherry, raspberry, hawthorn or red bayberry.

Beneficial effect of the present invention is: carry out fresh-keeping by extracting bio-preservative from Chinese medicine to fruit, 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.
