Description
Technical field
The present invention relates to a kind of composite preservative, be specifically related to a kind of to there is composite coating preservative containing crataegutt of anti-oxidant, antagonistic property and preparation method thereof and application, belong to fresh agricultural products technical field of preservation of fresh.
Background technology
Hawthorn (CrataeguspinnatifidaB.) is rose family may, has long health care and medicinal history in China.From nineteen fifties, people just start to study the chemical composition of leaves of Hawthorn, confirm that wherein Flavonoid substances content is up to 1.8% ~ 2%, is 20 ~ 120 times of fruit content wherein containing a large amount of flavones and crataegolic acid, chlorogenic acid, choline, volatilization wet goods.Leaves of Hawthorn has the multiple effects such as moistening lung cardiac stimulant, anti-cancer and cancer-preventing, hypotensive, reducing blood lipid, prevention of arterial sclerosis, is just day by day subject to people's attention in recent years.Principle active component-the flavone compound of leaves of Hawthorn, has the multiple physiologically actives such as anticancer, anti-oxidant, antibacterial.China soil is vast, there is a large amount of leaves of Hawthorn resources, about the application of crataegutt in the fresh agricultural products post-harvest fresh-keepings such as fresh fruit, dish, bacterium, there is not been reported, therefore leaves of Hawthorn is developed and utilized, therefrom extract natural anti-oxidation, bacteriostasis efficacy composition is applied to the fresh-keeping of the fresh agricultural products such as fruit, dish, bacterium, not only open the new way of leaves of Hawthorn efficiency utilization, simultaneously also for fresh agricultural products wide spectrum, exploitation that is efficient, multifunctional natural antistaling agent provide new approaches, safe, the green preservation realizing fresh agricultural products is had important practical significance.
Existing fresh agricultural products is fresh-keeping adopts fresh chemically more, coating-film fresh-keeping is more common in wax liquid film, though these fresh-keeping measures are obtaining certain effect in varying degrees, but the residual quantity of chemical preservative is larger, long-term absorption easily causes " three cause ", i.e. carcinogenic, teratogenesis, mutagenesis, its security is subject to the generally query of people; And most coating-film fresh-keeping generally only plays certain choke, the wet effect of resistance.Along with consumer's craving for green, organic food, it is fresh-keeping that fresh agricultural products is fresh-keeping is badly in need of finding a kind of green, crude antistaling agent that is efficient, broad-spectrum antibacterial carrys out substituted chemistry.Therefore, the present invention is by will the flavones that extract from leaves of Hawthorn and water-soluble good CMC compound, develop and a kind ofly novel there is antioxidation activity, the antibacterial multifunctional natural composite coating preservative had no side effect of high-efficiency broad spectrum, have broad application prospects.
Summary of the invention
, its security comparatively large for existing fresh agricultural products employing fresh chemically residual quantity is subject to consumer and queries; And coating antistaling agent only has certain choke, the wet effect of resistance, lack the problem of the multifunctional comprehensive fresh-keeping effects such as anti-oxidant and suppression microbial activities, the invention provides a kind of composite coating preservative containing crataegutt and preparation method thereof and application
Present invention also offers a kind of preparation method containing crataegutt composite coating preservative and application, by improving flavones dissolution process, improving flavones meltage, strengthen its anti-oxidant and bactericidal effect.
The technical scheme that the present invention is adopted to achieve these goals is:
The invention provides a kind of composite preservative containing crataegutt, be made up of following raw material: crataegutt 0.5-1.5 part, CMC 10-30 part, glycerine 30-40 part, calcium chloride 5-10 part, polyethylene glycol 10-20 part, Tween-20 0.3-0.5 part, 1000 parts, water.
Further, the molecular weight of described polyethylene glycol optimization is 200-600.
Further, the extraction of described crataegutt adopts following methods to obtain:
(1) powder of leaves of Hawthorn is mixed according to solid-liquid ratio 1:20 (g/mL) with 70vol% ethanolic solution, then acetic acid adjust ph is added, add after stirring in supersonic extractors, 50 DEG C are warming up to the heating rate of 3-5 DEG C/min, under power is 500W condition, re-extract three times;
(2) merge extract and filter, filtrate to during close to Transparent color through extraction into ethyl acetate, is removed ethyl acetate layer with separatory funnel, then is concentrated in a rotary evaporator, then freeze drying, obtain crataegutt.
Further, in step (1), described in add acetic acid adjust ph be 4-5.
Further, the time of described extraction is 20min.
Present invention also offers a kind of preparation method of composite preservative, comprise the following steps:
(1) weight portion CMC, calcium chloride, polyethylene glycol, Tween-20 are mixed with water, ultrasonic wave added dissolves, and stirs, obtains CMC base fluid;
(2) parts by weight of glycerin is mixed with crataegutt, after stirring, obtain flavones-glycerine mixed liquor;
(3) flavones-glycerine mixed liquor is mixed with CMC base fluid, stir, obtain compositional liquor;
(4) compositional liquor is carried out bubble-free in vacuum outgas to compositional liquor under vacuum conditions.
In addition, present invention also offers the application of composite coating preservative in fresh agricultural products is fresh-keeping of preparation.
The using method of composite coating preservative provided by the invention is: select fresh, without the agricultural product such as fresh fruit, dish, bacterium that rot, have no mechanical damage, after cleaning up by the clean tap water of flowing, naturally dry, then infusion method or spray-on process is adopted to be coated with the coating antistaling agent of last layer crataegutt-CMC compound at raw material surface uniform, carry out after natural air drying packing, storing and transporting, good fresh-keeping effect can be played.
In the process that the present invention extracts at crataegutt, by changing Alcohol system pH, farthest can keep the stability extracting flavones in solution, reducing the destruction of other extraction conditions to active ingredient; Meanwhile, change solution system pH value, also can reduce the solubility of impurity component in ethanolic solution, thus improve object---the recovery rate of crataegutt and purity.The composite coating preservative of the present invention's exploitation, in compound process, first carries out premixed by raw material, can improve the meltage of crataegutt in CMC base fluid; The collaborative anti-oxidant and bacteriostatic activity of this composite preservative is significantly improved by the compound of the two.
Beneficial effect of the present invention is:
(1) recovery rate of crataegutt and purity high; Crataegutt and CMC compound, it is anti-oxidant, bacteriostatic activity significantly improves, and natural, the nontoxic pair of this composite preservative remains;
(2) by optimizing flavones dissolution process, improving flavones content in antistaling agent, strengthening anti-oxidant, the bacteriostatic activity of composite preservative;
(3) each component synergy of composite preservative provided by the invention, by adding the coalescents such as calcium chloride, polyethylene glycol, Tween-20 in right amount, improve hygroscopicity, the homogeneity of composite preservative film, strengthen the integrality of film forming, do not ftracture after air-dry, make film not only have good choke, moisture barrier property, have excellent anti-oxidant, antibacterial effect, fresh-keeping effect is obvious simultaneously; The each component environmental protection of the present invention, good water solubility, easy cleaning, nontoxic pair remains, and has wide market prospects.
