Description
Technical field
The present invention relates to the field of preserving fruit and vegetable utilizing, the bio-preservative extracted from honeysuckle specifically and the application in strawberry preservation thereof.
Background technology
Honeysuckle, has another name called two flowers, and be dry flower or the flower just opened of Caprifoliaceae woodbine honeysuckle, in China, most area all has production, is China's traditional Chinese medicine material, taste is sweet, cold in nature, clearing heat and detoxicating, wind-heat dissipating.Modern chemical analysis and pharmacological evaluation prove, honeysuckle have broad-spectrum antiseptic, antiviral, antitumor, strengthen immunity and antipyretic and anti-inflammatory, cholagogic, protect the liver, lipopenicillinase, antifertility, hemostasis, the pharmacological action such as antiulcer.It is reported, the whole nation has the bud of more than 20 Plants to be used as medicine when honeysuckle, is all Caprifoliaceae woodbine.Owing to having special drug effect, therefore become the study hotspot of Chinese herbal medicine in recent years.Containing cyanidenon in honeysuckle, isochlorogenic acid, the multiple compounds such as chlorogenic acid and flavones, tradition thinks that chlorogenic acid is the principle active component of honeysuckle, but show according to modern medicine study, flavone compound wherein has reduction MCO, make coronary artery, cerebrovascular flow increases, the anti-rhythm of the heart, softening blood vessel, hypoglycemic, the effects such as blood fat, simultaneously it or a kind of natural antioxidant, there is Superoxide anion free radical in removing human body anti-ageing, increase the physiological activity of immunity of organisms, therefore its biologically active becomes the focus of people's research day by day.
Strawberry flavor is sweet, cool in nature, has moistening lung to promote the production of body fluid, the effect such as strengthening the spleen and stomach, and eat several strawberries after meal, contribute to digestion appetizing, invigorating the spleen is promoted the production of body fluid.Recent physician finds, often edible strawberry is to preventing and treating artery sclerosis and coronary heart disease is also benefited.According to foreign medical science man research, containing anticancer component in strawberry, can the growth of inhibition tumor cell.In Europe, the laudatory title that strawberry is enjoyed for a long time " fruit queen ", and by the health food as children and the elderly.
More the nutritional labeling of strawberry, easily by human consumption, absorption, is eaten and also can not be suffered from cold or get angry, and is all-ages healthy food.Carrotene contained in strawberry is the important substance of synthetic vitamin A, has improving eyesight nourishing the liver effect.It also containing pectin and abundant dietary fiber, can help digest, unobstructed stool.Strawberry all has certain nourishing opsonic action to intestines and stomach and anaemia.Strawberry, except can preventing scurvy, also has good effect to preventing and treating artery sclerosis, coronary heart disease.Strawberry is the plant that tanin content enriches, and the adsorbable absorption with stoping carcinogenic chemical, has protective effect on cancer risk in vivo.The U.S. lists ten large beauty foods in strawberry.
Women often pastures the certain kind of berries, all has health-care effect to skin, hair.Strawberry is described as " magical fruit " in Germany.Strawberry can also be lost weight, because it contains a kind of material being aspartic acid, certainly but gently can remove " slag " in body.Traditional Chinese medicine is thought, the sweet acid of strawberry nature and flavor, cool.Can moistening lung promote the production of body fluid, strengthening the spleen and stomach, blood yiqi, removing pattogenic heat from the blood and toxic material from the body, have auxiliary curative effect to diseases such as artery sclerosis, hypertension, coronary heart disease, scurvy, colon cancers.
Strawberry belongs to berries fruit, delicious flavour, rich in nutritive value, but the respiratory intensity of strawberry is large, and protective tissue is poor, and 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 strawberry 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 and a kind ofly extract the method for bio-preservative and the application in strawberry preservation thereof with the flower of honeysuckle and/leaf.
For achieving the above object, technical scheme of the present invention is: a kind of method extracting bio-preservative from honeysuckle, comprises the steps, 1, adopt pulverizer to pulverize on honeysuckle flower and/or leaf; 2, be that the ratio of 1:10-15 adds ethanolic solution with solid-liquid ratio by the honeysuckle flower of pulverizing and/or leaf, and be transferred to together in Microwave Extraction Apparatus and carry out Microwave Extraction, Extracting temperature is 60-70 DEG C, and the working time is 10-20min, and microwave power is 500-800w; 3, by extracting liquid filtering, filtrate is obtained, and in 2-4 DEG C of storage.
Preferably: described ethanol solution concentration is 50-80%.
Preferably: add rotor in described leaching process and stir.
The present invention also provides a kind of application of bio-preservative in strawberry preservation of extracting according to method described in claim 1, immerses 1-2min in bio-preservative, dry, then preserve with after PE-PP composite waterproofing membrane after the jujube newly plucked being rejected insect pest and mechanical damage fruit; Duration of storage is made regular check on, in time the abnormal fruit of cleaning.
Preferably: described jujube holding conditions is relative humidity 90-95%, temperature is 2 ± 0.5 DEG C.
Beneficial effect of the present invention is: the present invention carries out fresh-keeping for raw material extracts bio-preservative to jujube with the flower of honeysuckle and/leaf, safety.Nontoxic, nuisanceless, fresh-keeping for jujube of chemical bactericide, anticorrisive agent can be replaced, avoid the problem such as pollution, food security of chemical bactericide to environment.
