Abstract
The present invention relates to a method for extracting a plant mildew proof refreshing agent. Lilac is adopted, crushed, soaked by adding water and distilled by water vapour; fraction-distillate is extracted; the single extraction is carried out by a solvent; then, the extracted upper layer solution is carried out with the secondary extraction by a sodium bicarbonate solution; afterwards, the upper layer solution of the secondary extraction is carried out tertiary extraction by a sodium carbonate solution; then, a solvent in the lower layer solution of the tertiary extraction is volatilized, namely that the plant mildew proof refreshing agent is obtained. The active validity period of the method for extracting a plant mildew proof refreshing agent can reach 15 months. The present invention can refresh green peppers for 60 days, grapes for 60 days, melons for 20 days and pears for 45 days, and the effect is good. The method for extracting a plant mildew proof refreshing agent has strong wound infection performance to fruits and vegetables, and has obvious and lasting inhibiting effect to penicillium expansum and aspergillus niger of low temperature resistance, low O2 resistance and high CO2 resistance. The present invention has the advantages of convenient application and simple storage and transportation.
Description
Technical field
The invention belongs to the plant antistaling agent, particularly a kind of extracting method of plant anti-mould fresh keeping agent.
Background technology
Anticorrosion is that fresh fruit of vegetables is adopted requisite sport technique segment in the back circulation, and relies on antisepsis antistaling agent to handle, and the morbidity that suppresses due to the microbial infections such as fungi, bacterium, saccharomycete is rotted.Anticorrisive agent is divided into two types in chemical synthesis preparation and natural extract preparation.For a long time, because of chemicals drug effect height, long half time, cost are low, the natural extract stable effective ingredients is poor, the half-life is short, cost is high, and antiseptic preservation of fruits and vegetables is continued to use chemicals always, or even agricultural chemicals.Along with pollution-free food and environmental protection ideas are popularized, safety, crude antistaling agent research and development have efficiently become the research focus of domestic and international preserving fruit and vegetable utilizing.
Summary of the invention
Technical problem to be solved by this invention is: the extracting method that a kind of plant anti-mould fresh keeping agent is provided.
Technical scheme of the present invention is:
A kind of extracting method of plant anti-mould fresh keeping agent, it is characterized in that: adopt flos caryophylli, with its pulverizing, add the water logging bubble, carry out steam distillation again, extract cut-distillate, distillate is used the solvent single extraction again, the upper strata liquid of extraction is used the sodium bicarbonate solution reextraction again, the upper strata liquid of reextraction is again with three extractions of sodium carbonate liquor, with the solvent evaporates in its subnatant, stay composition and be the plant anti-mould fresh keeping agent again.
Solvent is following a kind of: ether, ethanol, carrene, chloroform, ethyl acetate.
Sodium bicarbonate solution and sodium carbonate liquor concentration are 5%.
Adopt flos caryophylli,, add the water logging bubble more than 18 hours its pulverizing, carry out steam direct distillation distillation 4-12 hour again, extract cut-distillate, distillate is used the solvent single extraction again, solvent load is: cloves: solvent=100g: 200-400ml; The upper strata liquid of extraction is used 5% sodium bicarbonate solution reextraction again, and 5% sodium bicarbonate solution consumption is: cloves: 5% sodium bicarbonate solution=100g: 100ml; With three extractions of 5% sodium carbonate liquor, 5% sodium carbonate liquor consumption is the upper strata liquid of reextraction: cloves: 5% sodium carbonate liquor=100g: 100ml again; With the solvent evaporates in its subnatant, stay composition and be the plant anti-mould fresh keeping agent again.
Effect of the present invention is:
The extracting method of plant anti-mould fresh keeping agent its to stronger, low temperature resistant, the anti-low O of fruits and vegetables wound infection
2, anti-high CO
2The penicillium expansum and the inhibitory action of aspergillus niger obviously lasting.Use conveniently, the condition of depositing and transporting is also simpler.The activity of the extracting method of plant anti-mould fresh keeping agent was valid up to 15 months.The extracting method of plant anti-mould fresh keeping agent can be to pimento fresh-keeping 60 days, grape fresh-keeping 60 days, and fresh-keeping 20 days of muskmelon, fresh-keeping 45 days of pears, respond well.
The specific embodiment
Example one, employing flos caryophylli with its pulverizing, added the water logging bubble 18 hours, carry out steam direct distillation distillation 5 hours again, extract cut-distillate, distillate is used the etoh solvent single extraction again, the alcohol solvent consumption is: cloves: alcohol solvent=100g: 200ml; The upper strata liquid of extraction is used 5% sodium bicarbonate solution reextraction again, and 5% sodium bicarbonate solution consumption is: cloves: 5% sodium bicarbonate solution=100g: 100ml; With three extractions of 5% sodium carbonate liquor, 5% sodium carbonate liquor consumption is the upper strata liquid of reextraction: cloves: 5% sodium carbonate liquor=100g: 100ml again; With the volatilization of the etoh solvent in its subnatant, stay composition and be the plant anti-mould fresh keeping agent again.
Example two, employing flos caryophylli with its pulverizing, added the water logging bubble 20 hours, carry out steam direct distillation distillation 8 hours again, extract cut-distillate, distillate is used the methylene chloride single extraction again, the methylene chloride consumption is: cloves: dichloromethane solvent=100g: 300ml; The upper strata liquid of extraction is used 5% sodium bicarbonate solution reextraction again, and 5% sodium bicarbonate solution consumption is: cloves: 5% sodium bicarbonate solution=100g: 100ml; With three extractions of 5% sodium carbonate liquor, 5% sodium carbonate liquor consumption is the upper strata liquid of reextraction: cloves: 5% sodium carbonate liquor=100g: 100ml again; With the volatilization of the methylene chloride in its subnatant, stay composition and be the plant anti-mould fresh keeping agent again.
