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 antistaling agent made from plant waste.
Background technology
In recent years, along with China's agricultural structure is to high-quality, highly efficient and productive future development, the output of fruits and vegetables has had a large amount of raisings, but because fruits and vegetables production has very strong seasonality, regionality and mutability, 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 serious 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.For a long time, people mainly adopt chemical synthesis material as antistaling agent, though there is good preservation and antisepsis effect, a lot of synthetics confrontation healths have certain harm, and people is carcinogenic in serious even can making, teratogenesis, mutagenesis.Consideration for people to factors such as environment, health, the research of antistaling agent is gradually to natural, safe and effective future development, the application of chemical bactericide is more and more subject to people's query, substitute technology (as toga, salt processing etc.) becomes the focus of Recent study, but these technology not yet obtain satisfied commercial effect so far.It is current fresh-keeping main method that refrigeration is used in conjunction with chemical bactericide.Low temperature can suppress some pathogen growths, reduce Some Disease and occur, but some low temperature resistant maize ear rot bacterium that cause rots as the existence of brown rot germ can cause fruits and vegetables and meat, the essential chemical bactericide that uses.Yet, adopt chemical bactericide not only can cause the problems such as pathogenic bacteria develop immunity to drugs, environmental pollution, and its residual meeting serious threat mankind's health.Therefore research and develop that have more characteristic and harmless, environment-friendly and green, cost is low, fresh-keeping effect is remarkable, can be applicable to the serial fresh products of multiple fruits and vegetables, meat 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, and this Preserving 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 by the raw material of following percentage by weight: Jasmine 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, is made by the raw material of following percentage by weight: 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 extracts the dry flower after essential oil, medicinal extract.In Jasmine, contain abundant flavones and flavones ingredient, the bacteriums such as proteus vulgaris, staphylococcus, bacillus subtilis, Escherichia coli are had to certain inhibitory action.
Arhat pomace of the present invention is that Momordica grosvenori extracts the slag producing after Momordica-Glycosides.Flavonoid substances in arhat pomace has more significant inhibitory action to the growth of gram-positive bacteria, as white is read 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 inhibitory action.
The flavones that pomelo peel in raw material of the present invention contains and Flavonoid substances are to gram-positive cocci, as staphylococcus, streptococcus, Diplococcus pneumopniae, bacillus anthracis etc., and gram-Negative bacillus, as Escherichia coli, shigella dysenteriae, typhoid bacillus, proteus etc. have inhibitory action.
The antistaling agent made from plant waste of the present invention is made powdery, converts into wateryly during use, and convenient preservation, extends the term of validity of antistaling agent.
The application of the antistaling agent made from plant waste of the present invention in vegetables, fruit or meat fresh-keeping.
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, added 3~5 times of water of raw material, at 40 ℃~60 ℃ temperature, refluxing extraction 50~100min, obtains extract; Starch is added in extract, ultrasonic wave disperses again, the liquid that is uniformly mixed, and compression, spraying is dry, obtains antistaling agent.
During use, add water, the ratio of antistaling agent and water is 1:20~1:30, mixes, and puts into vegetables, fruit or meat, soaks 3~8 minutes, pulls out, and after drying, vegetables and fruits are preserved also and can be refrigerated under room temperature condition, 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 abundant Flavonoid substances, have bacteriostasis, prevent the intrusion of microorganism, alleviate and need rotting of preservation liquid.
(2) antibacterial in the present invention and oxidation resistant active ingredient, is to extract and obtain from the plant waste of integration of drinking and medicinal herbs, harmless, and in raw material, does 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, makes full use of resource, and the antistaling agent cost of making is ultralow.
(4) antistaling agent of the present invention is made powdery, converts into wateryly during use, and convenient preservation, extends the term of validity of antistaling agent.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described, but the present invention is not limited to these embodiment.
