Abstract
The present invention relates to technical field of preservation of fresh, and in particular to a kind of fruit and vegetable fresh-keeping agent containing Fructus Cannabis extract is made of Fructus Cannabis extract, Prochloraz and auxiliary agent, and the quality of the Fructus Cannabis extract and Prochloraz accounts for the 25-60% of antistaling agent gross mass.Prochloraz and Fructus Cannabis extract have synergistic function in fruit and vegetable fresh-keeping agent of the invention, can significantly improve drug effect, reduce antistaling agent usage amount, reduce chemical preservative harm to the human body and reduce the pollution to environment；Simultaneously because Fructus Cannabis extract and Prochloraz are different to the mechanism of action of germ, it can effectively slow down the generation of germ resistance after compounding, reduce fresh-keeping cost.
Description
Technical field
The present invention relates to technical field of preservation of fresh, and in particular to a kind of fruit and vegetable fresh-keeping agent containing Fructus Cannabis extract.
Background technique
With the continuous improvement of living standards, people increasingly focus on the consumption of fruits and vegetables, and fruits and vegetables should be required fresh, battalion
It is high to support value, and requires safety clean, therefore, the fresh-keeping of fruits and vegetables has been to be concerned by more and more people.Postharvest technology of fruits and vegetables is to control
Based on the growth of microorganism processed, the method generallyd use has 2 kinds: one is physical methods, such as low temperature, decompression, controlled atmosphere and electricity
From processing etc., but its investment is big, energy consumption is more, at high cost, it is difficult to which universal and fresh-keeping effect is limited.Another kind is chemical method, often
Chemical preservative is with regard to this method.
Chemical preservative is that a kind of chemically synthesized fungicide can efficiently control although its preservation and antisepsis effect is preferable
The growth and breeding of germ achievees the purpose that fruits and vegetables is delayed to rot, but same chemical preservative, which is used for a long time, so that germ is generated
Drug resistance, and increasing dosage is generallyd use in order to reach fresh-keeping purpose.Long-term, high-dose uses chemical preservative meeting dirt
Environment is contaminated, people, which eat this processed fruits and vegetables, also can bring problems to human health.Therefore develop efficiently, wide spectrum and
The fruit and vegetable fresh-keeping agent of low toxicity has very big economic value and wide application prospect.
The information disclosed in the background technology section is intended only to increase the understanding to general background of the invention, without answering
When being considered as recognizing or imply that the information constitutes the prior art already known to those of ordinary skill in the art in any form.
Summary of the invention
To overcome above-mentioned existing issue, the present invention provides a kind of fruit and vegetable fresh-keeping agent containing Fructus Cannabis extract, efficiently,
Wide spectrum, low toxicity can effectively delay fruit vegetables storing period.
To achieve the above object, the present invention provides the following technical scheme that
A kind of fruit and vegetable fresh-keeping agent containing Fructus Cannabis extract, is made of Fructus Cannabis extract, Prochloraz and auxiliary agent, described
The quality of Fructus Cannabis extract and Prochloraz accounts for the 25%-60% of antistaling agent gross mass.
Preferably, the mass ratio of the Prochloraz and Fructus Cannabis extract is 1-5:9-1.
Preferably, the mass ratio of the Prochloraz and Fructus Cannabis extract is 1:6.
Preferably, the process flow of the Fructus Cannabis extract are as follows: dry fructus cannabis, crushed 50-60 mesh, add
The ethyl alcohol that 6-8 times of mass fraction is 90% is heated to 60-70 DEG C, impregnates 18-22h, and filtering is extracted 1 time again after collecting filtrate,
Merging filtrate is concentrated into raw material containing 1g in 1ml solution.
Preferably, the dosage form of the antistaling agent is wettable powder or water dispersion granule.
Preferably, the auxiliary agent is made of several in dispersing agent, wetting agent, disintegrating agent, binder and filler.
The present invention also provides the application methods of the fruit and vegetable fresh-keeping agent, antistaling agent are diluted with water 600-900 times,
Even sprinkling, is subject to and is uniformly covered with droplet.
The present invention also provides application of the fruit and vegetable fresh-keeping agent in grape, citrus, tomato and capsicum keeping-freshness storage.
Compared with prior art, the invention has the following beneficial effects:
(1) Prochloraz and Fructus Cannabis extract have synergistic function in fruit and vegetable fresh-keeping agent of the invention, can be significant
Drug effect is improved, antistaling agent usage amount is reduced, reduce chemical preservative harm to the human body and reduces the pollution to environment.
(2) fruit and vegetable fresh-keeping agent Prochloraz of the invention and Fructus Cannabis extract are different to the mechanism of action of germ, compounding
The generation that germ resistance can effectively be slowed down afterwards, reduces fresh-keeping cost.
(3) fruit and vegetable fresh-keeping agent of the invention can extend storage period, be effectively reduced caused by storage period fruits and vegetables infect because of germ
Loss.

Subjects: citrus penicillium italicum, capsicum anthrax-bacilus
Test operation:
1. diluting, it is dense that 5 series mass being arranged reagent agent acetone solution with 0.1% Tween-80 aqueous solution
Degree.
It is added in conical flask 2. aseptically, sterilising medium is melted, is successively drawn from low concentration to high concentration
Medical fluid 5ml after dilution, is separately added into above-mentioned conical flask, sufficiently shakes up.Then it is 9cm's that equivalent, which pours into 3 diameter above,
In culture dish, the drug containing tablet of respective concentration is made.0.1% Tween-80 processing without medicament is set and makees blank control, often
4 repetitions of a processing.
3. aseptically using the sterilization punchers of diameter 5mm, cutting bacterium from colony edge cultured pathogen
Cake after cultivating 8d, is surveyed pure culture biscuits involvng inoculation in drug containing tablet center with inoculator as cultivating in 25 DEG C of incubators with slide calliper rule
Colony diameter is measured, each bacterium colony diameter is measured perpendicularly using the crisscross method, takes its average value.According to reagent agent concentration
Logarithm and corresponding mycelial growth inhibition rate make regression analysis, calculate the EC50 of each medicament, and calculate and mix according to Sun Yunpei method
The co-toxicity coefficient (CTC value) of agent.
Survey toxicity index (ATI)=(standard agent LC50/ reagent agent LC50) × 100.
Percentage composition+B the medicament toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
The percentage composition of B in agent.
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100.
According to the synergy criteria for classifying: co-toxicity coefficient (CTC) >=120 shows as synergistic effect；Co-toxicity coefficient (CTC)≤
80 show as antagonism；80 < co-toxicity coefficient (CTC) < 120 shows as summation action.Experimental result is shown in Table 1-2.
