A kind of antistaling agent made from plant waste
Technical field
The present invention relates to the technical field of antistaling agent, particularly a kind of make with plant waste fresh-keepingAgent.
Background technology
In recent years, along with China's agricultural structure is to high-quality, highly efficient and productive future development, fruits and vegetablesOutput had a large amount of raisings, but because fruits and vegetables are produced and had very strong seasonality, regionality and easySex change, fruits and vegetables are very easily subject to the impact of the factors such as physics, physiology and pathology and go bad after adopting, and cause tightHeavy loss. According to investigations, the rear loss late of adopting of China's fruits and vegetables is about 20%~30%. And well-known,Meat is easy to go bad, and particularly, under the normal temperature environment in summer, the nutritive value of meat is reduced.
Antistaling agent is in the market divided into two large classes: chemical synthesis antistaling agent and crude antistaling agent. LongSince phase, people mainly adopt chemical synthesis material as antistaling agent, though there is good preservation and antisepsisEffect, but a lot of synthetics confrontation health has certain harm, and the serious people that even can make causesCancer, teratogenesis, mutagenesis. Consideration for people to the factor such as environment, health, the research of antistaling agentTo natural, safe and effective future development, the application of chemical bactericide is more and more subject to people graduallyQuery, substitute technology (as toga, salt processing etc.) becomes the focus of Recent study, but theseTechnology not yet obtains satisfied commercial effect so far. It is fresh-keeping at present that refrigeration is used in conjunction with chemical bactericideMain method. Low temperature can suppress some pathogen growths, reduce Some Disease and occur, but some is resistance toThe maize ear rot bacterium that causes of low temperature is rotted as the existence of brown rot germ can cause fruits and vegetables and meat, the essential chemistry that usesBactericide. But, adopt chemical bactericide not only can cause that pathogenic bacteria develop immunity to drugs, environmental pollutionEtc. problem, and its residual meeting serious threat mankind's health. Therefore research and develop have more characteristic,And harmless, environment-friendly and green, cost is low, and fresh-keeping effect is remarkable, can be applicable to multiple fruits and vegetables, meatThe serial fresh products of class storage is research direction and the focus of this area.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of antistaling agent made from plant waste, shouldPreserving Reagent Freshening Effect is remarkable, not containing any additive, and safety non-toxic, environmental protection, cost is low.
For achieving the above object, the present invention adopts following technical scheme:
An antistaling agent made from plant waste, is made up of the raw material of following percentage by weight: jasmineFlower slag 40%~50%, arhat pomace 15%~25%, hop residue 15%~20%, pomelo peel 10%~15%,Starch 5%~10%.
The antistaling agent made from plant waste of the present invention, preferably, by following percentage by weightRaw material make: Jasmine slag 44%, arhat pomace 20%, hop residue 17%, pomelo peel 12%,Starch 7%.
Jasmine slag of the present invention is the dry flower after jasmine fresh flower scenting tea, or extractsDry flower after essential oil, medicinal extract. In Jasmine, contain abundant flavones and flavones ingredient, to generalThe bacteriums such as logical proteus, staphylococcus, bacillus subtilis, Escherichia coli have certain inhibition to doWith.
Arhat pomace of the present invention is that Momordica grosvenori extracts the slag producing after Momordica-Glycosides. Momordica grosvenoriFlavonoid substances in slag has more significant inhibitory action to the growth of gram-positive bacteria, as whiteRead coccus, aerobacteria, bacillus subtilis, Sarcina lutea.
Hop residue of the present invention is while producing beer, the slag that hops produces after extraction.The contained lupulones of hops is to gram-positive bacterium, as Bacillus anthracis, bacillus cereus,Corynebacterium diphtheriae, Diplococcus pneumopniae, staphylococcus aureus, tubercle bacillus, hay bacillus etc. have inhibitionEffect.
The flavones that pomelo peel in raw material of the present invention contains and Flavonoid substances be to gram-positive cocci, asStaphylococcus, streptococcus, Diplococcus pneumopniae, bacillus anthracis etc., and gram-Negative bacillus, as greatlyEnterobacteria, shigella dysenteriae, typhoid bacillus, proteus etc. have inhibitory action.
The antistaling agent made from plant waste of the present invention is made powdery, when use, convert into watery,Convenient preservation, extends the term of validity of antistaling agent.
The antistaling agent made from plant waste of the present invention is in vegetables, fruit or meat fresh-keepingApplication.
The present invention also provides the preparation method of the antistaling agent made from plant waste, as follows:
Jasmine slag, arhat pomace, hop residue, pomelo peel are pulverized, are added 3~5 times of water of raw material,At 40 DEG C~60 DEG C temperature, refluxing extraction 50~100min, obtains extract; Again starch is added and carriedGet in liquid, ultrasonic wave disperses, the liquid that is uniformly mixed, and compression, spraying is dry, obtains antistaling agent.
When use, add water, the ratio of antistaling agent and water is 1:20~1:30, mixes, and puts intoVegetables, fruit or meat, soak 3~8 minutes, pulls out, and after drying, vegetables and fruits are in room temperatureUnder condition, storage also can refrigerate, meat refrigeration. If need fresh-keeping foodstuff to be covered with preservative film, effect is better.
Compared with prior art, beneficial effect of the present invention is:
(1) the Jasmine slag in raw material of the present invention, arhat pomace, hop residue, pomelo peel contain richRich Flavonoid substances, has bacteriostasis, prevents the intrusion of microorganism, alleviates and needs preservation liquidRot.
(2) antibacterial in the present invention and oxidation resistant active ingredient, is from the plant waste of integration of drinking and medicinal herbsExtract and obtain, harmless, and in raw material, do not contain any additive, green safety.
(3) the present invention, with plant waste as raw material, is turned waste into wealth, and promotes the value of waste material, fullyUtilize resource, the antistaling agent cost of making is ultralow.
(4) antistaling agent of the present invention is made powdery, converts into wateryly when use, and convenient preservation, extends and protectThe term of validity of fresh dose.
