Abstract
The invention relates to a method for extracting a biological fresh-keeping agent from herba houttuyniae. The method comprises the following steps of cleaning and selecting herba houttuyniae to remove impurities, crushing the herba houttuyniae, putting the crushed herba houttuyniae into a pot, adding water into the pot according to a material-liquid ratio of 1: 1-3, carrying out immersion for 3-4h, carrying out heating by a big fire until boiling, carrying out decoction by a slow fire for 20-30min, carrying out filtration, collecting the filtrate, preserving the filtrate by a refrigerator with a temperature of 2-4 DEG C, adding water into the residue according to a material-liquid ratio of 1: 0.5-1, carrying out immersion for 1-2h, carrying out decoction for 30-60min, carrying out filtration, merging the filtrates and preserving the mixed filtrate by a refrigerator with a temperature of 2-4 DEG C. The biological fresh-keeping agent extracted from traditional Chinese medicines is used for fresh-keeping of fruits and is safe. The biological fresh-keeping agent is nontoxic and harmless, can replace a chemical bactericide and an antiseptic for fruit fresh-keeping, prevents chemical bactericide-caused environment pollution and is safe for foods.
Description
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
Cordate houttuynia taste is pungent, cold, clearing heat and detoxicating, detumescence can treat sore, promoting urination and removing dampness, stomach strengthening and digestion promoting, by the lung carbuncle, sore swollen toxin, hemorrhoidal hemorrhage, retention of heat in the spleen and stomach etc. of controlling real heat, heat poison, damp evil, disease heat are trouble.Modern pharmacology experiment shows, this product has antibacterial, antiviral, effect such as raising immunity of organisms, diuresis etc.Clinical report cordate houttuynia is widely used in the various disease conditions such as the treatment infection of the upper respiratory tract, influenza, lung abscess, cancerous hydrothorax, lung cancer, cervical erosion, acute bacillary dysentery, acute icterohepatitis, the popular parotid gland.From cordate houttuynia, also isolate a kind of cancer-resisting material abroad; Except to cancer of the stomach effectively except, and also have certain therapeutic action to medium and advanced lung cancer, choriocarcinoma, chorioadenoma, the carcinoma of the rectum.In Japan, cordate houttuynia is favored, and except the traditional Chinese prescription of employing, medicative diet for food therapy, also applies in functional health-care food (tea, beverage etc.) mode.
Four of cordate houttuynia acts on introduction greatly: 1, resisting pathogenic microbes effect, suppresses staphylococcus aureus, Bacillus influenzae, Diplococcus pneumopniae.2, diuresis, makes telangiectasis, increases renal blood flow and secretion of urine, so also for the puckery pain of pollakiuria of urinary tract infections.3, strengthen immune system effect, improve the leukocytic phagocytosis of chronic bronchitis patient.4, antitumor action, improves the CAMP in cancer cell and suppresses EC.
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 is cleaned, removing foreign material;
2, cordate houttuynia is pulverized;
3, the cordate houttuynia of flour 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 herba houttuyniae powder is broken 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 mulberries, blueberry, cherry tomato, strawberry.
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.
