Abstract
The invention discloses a kind of technique utilizing Eupatorium adenophorum to prepare antistaling agent.This technique comprises the steps: a, Eupatorium adenophorum ground plant is ground into broken end; B, broken for Eupatorium adenophorum end is used water and alcohol immersion respectively, obtain water extract and alcohol extract; Water extract reduced pressure concentration, drying obtain the water extracted immersing paste; Alcohol extract reduced pressure concentration, obtain alcohol steep concentrate, then drying obtains ethanol extract; C, the filter residue after lixiviate to be carbonized, obtained active carbon; D, by the water extracted immersing paste of certain mass ratio He ∕ or ethanol extract, active carbon, iron powder, quick lime, salt, cinder mixing, obtained powdery antistaling agent.Alcohol steep concentrate and the flooding cream ratio by weight 3 ~ 5 ︰ 1 is mixed, champignon type antistaling agent can also be obtained.Fumigation type antistaling agent of the present invention, utilizes the volatilization naturally of ethanol to reach stifling fresh-keeping effect; The antistaling agent of powdery, has the function of dehydration, sterilization and deoxidation.
Description
Technical field
The invention belongs to forestry biomass technical field, be specifically related to a kind of technique utilizing Eupatorium adenophorum to prepare antistaling agent.
Background technology
Eupatorium adenophorum (Ageratina adenophora) is composite family perennial herb or undershrub, and in originating in, Mexico to Costa Rica one of South America is with.Import the most southern Cang Yuan, Geng Madeng county of Lincang Prefecture of Yunnan Province in the forties in 20th century into by Burma, now extensively distribute in the provinces and regions such as Yunnan, Guizhou, Sichuan, Guangxi, Chongqing, Hubei, Tibet of southwest, and with southwester eastwards, north spreads.By 2012, the soil of southwest 80% area had Eupatorium adenophorum to distribute, and only the distribution area in Yunnan Province just reaches more than 250 ten thousand hectares.Fertility due to Eupatorium adenophorum, the adaptive capacity to environment are extremely strong, and all can grow at the barren barren hill unoccupied place of arid, the top of a wall, Yan Kan, crack of stone, diffusion velocity is about 60 kms/year.But Eupatorium adenophorum has stronger toxicity, not even a blade of grass grows in place of arrival, and cattle and sheep are poisoning, heavy damage Vegetation community, influence ecological environment, garden landscape and agricultural production, is called as " killer " in plant kingdom, " No.1 instruction plant ".
So far, also thoroughly do not control the effective way of Eupatorium adenophorum diffusion, so, carry out the comprehensive utilization of Eupatorium adenophorum, wantonly spreading of its wild resource can be controlled to a certain extent, alleviate the destructiveness of Eupatorium adenophorum to ecological environment, but also can realize becoming evil into precious, play larger economic benefit and ecological benefits.At present, the comprehensive utilization major way of Eupatorium adenophorum has: Fodder making, fertilizer, biological pesticide, active carbon, edible fungus culturing matrix, building materials, fuel etc., but does not also make the report of antistaling agent about Eupatorium adenophorum.
Research shows: the citral in purple stem boneset extract has more significant anti-Aspergillus active in vitro, p-poly-umbellate form florigen, Thymol, nopinene, citrene, the monoterpenes such as caffeic acid, umbellate form flower lactone, forulic acid, taraxasterol, plant steroid compounds, sesquiterpenoids has good antibacterial activity, to sweet potato soft rot bacterium, Dalmatian chrysanthemum sickle-like bacteria, alternaria altemata, Escherichia coli, bacillus subtilis, bacillus thuringiensis, staphylococcus aureus, Strain of Pseudomonas Solanacearum, the former bacterium of cotton wilt, Phytophthora capsici pathogen, apple decay cause of disease bacterium and the former bacterium of rice blast all have inhibitory action, and flavonoids, Polyphenols, citrenes etc. have good oxidation resistance.Visible, Eupatorium adenophorum has the potentiality preparing plant source preservative.
Bacteriostatic activity due to Eupatorium adenophorum is not probably that single compound works, but the synergistic result of several compound, if extract arbitrary active ingredient in Eupatorium adenophorum, then may not reach best fresh-keeping effect.For this reason, the present invention is so that " No.1 instruction plant "---Eupatorium adenophorum is for primary raw material, adopt the method for the applicable large-scale production such as water and alcohol steep, extract the polarity in Eupatorium adenophorum plant and nonpolar active ingredient, be prepared into plant source preservative, provide new effective way by the recycling for Eupatorium adenophorum.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of technique utilizing Eupatorium adenophorum to prepare antistaling agent.
The technical solution adopted for the present invention to solve the technical problems is: utilize Eupatorium adenophorum to prepare the technique of antistaling agent, comprise the steps:
A, by Eupatorium adenophorum on the ground plant be ground into broken end;
B, broken for Eupatorium adenophorum end is used water and alcohol immersion respectively, obtain water extract and alcohol extract; Water extract reduced pressure concentration, drying obtain the water extracted immersing paste of powdery; Alcohol extract reduced pressure concentration, reclaims ethanol, obtains alcohol steep concentrate, the drier ethanol extract obtaining powdery;
C, the filter residue after Eupatorium adenophorum lixiviate in step b to be carbonized, obtained active carbon;
D, by the powdery the water extracted immersing paste of 10 ~ 30 weight portions with the cinder mixing of the salt of the quick lime of the iron powder of the active carbon of ∕ or ethanol extract, 0.5 ~ 4 weight portion, 40 ~ 50 weight portions, 1 ~ 3 weight portion, 0.5 ~ 3 weight portion, 10 ~ 20 weight portions, obtained powdery antistaling agent.
Cinder is the one of industrial solid wastes, the waste residue that thermal power plant, industry and civil boiler and other equipment fire coal are discharged, also known as slag.
Wherein, also comprise step e in above-mentioned technique, the alcohol steep concentrate obtained by step b and flooding cream mix by weight the ratio of 3 ~ 5 ︰ 1, obtain champignon type antistaling agent.
Wherein, in above-mentioned processing step a, Eupatorium adenophorum is the Fresh Plants of summer, harvesting in autumn.
Wherein, in above-mentioned processing step b, during alcohol extract reduced pressure concentration, enrichment factor is 10 ~ 50%.
The ratio of the volume before enrichment factor refers to the volume after concentrating and concentrates.
