Abstract
The present invention discloses an antistaling agent for fruits and vegetables and a production method thereof, which is mainly composed of (the dosage is weight part.) 300 to 500 of rosin, 100 to 300 of shellac, 300 to 500 of beeswax and 5 to 10 of thiabendazole (or 1 to 10 of potassium sorbate or sodium benzoate). The production method comprises the following steps that (1) the rosin and the shellac are dissolved in an ethanol solution; (2) the beeswax is homogenized or saponified; (3) a biological film base material is manufactured by mixing and emulsifying the (1) and the (2); (4) the thiabendazole or the potassium sorbate or the sodium benzoate are added in the (3) and uniformly stirred. The raw materials of the product are rich and can be obtained easily. The present invention has simple production method, and can form a semipermeable macromolecule biological film on the surfaces of fruits and vegetables. The present invention has the advantages of good refreshment effect and no toxic side effect.
Description
The invention belongs to the technical field that fruit or vegetables preserve, particularly relate to protective layer coated fruit or method for vegetable.
Fruits and vegetables is the indispensable important substance of human lives.But after vegetable and fruit is gathered, very easily rot and dehydration, not anti-storage and transportation have a strong impact on its commodity value, and economic loss is up to 20-50%.People have carried out big quantity research and exploration to this, proposed some fruit and vegetable fresh-keeping agents.But existing fruit and vegetable fresh-keeping agent price is higher, and effect is undesirable.The fruit and vegetable fresh-keeping agent that has is known from experience generation ill-effect and contaminated environment to the people; Can form the spot of some medicines after the use that has on the surface of fruits and vegetables, influence again neither attractive in appearance is edible.This is a still unsolved so far technical barrier.
The objective of the invention is to avoid above-mentioned weak point of the prior art and providing a kind of is raw material with the natural biological resource, is matrix with macromolecule semi permeability biomembrane, to the person poultry harmless, and fruit and vegetable fresh-keeping agent free from environmental pollution and production method thereof.
Purpose of the present invention can realize by following technical measures:
Fruit and vegetable fresh-keeping agent of the present invention mainly consists of (consumption is a weight portion):
Rosin 300-500 shellac 100-300 beeswax 300-500
Probenazole 5-10 (perhaps potassium sorbate or Sodium Benzoate 1-10)
Preparing fruit and vegetable fresh-keeping agent main component preferred weight ratio range of the present invention is: (consumption is a weight portion):
Rosin 250-350 shellac 150-250 beeswax 450-500
Probenazole 6-8 (perhaps potassium sorbate or Sodium Benzoate 4-7)
The optimum weight proportioning of fruit and vegetable fresh-keeping agent main component of the present invention is:
Rosin 300 shellac 200 beeswaxs 500
Probenazole 7 (perhaps potassium sorbate or Sodium Benzoate 6)
The production method of above-mentioned each component being made fruit and vegetable fresh-keeping agent of the present invention is:
1. press rosin: shellac: the weight proportion of ethanol=15: 10: 100 is dissolved in rosin and shellac
Ethanolic solution;
2. beeswax is carried out homogenize or by beeswax: the weight proportion of saponification agent=100: 1, with routine side
Method is carried out saponification to beeswax;
3. will 1. and 2. after mixing, emulsification make biofilm matrix;
4. in 3., add probenazole or potassium sorbate or Sodium Benzoate and stir and get final product.
Consumption of the present invention and using method:
1. 1 liter of antistaling agent of the present invention is added water 50-100 liter and make diluent, can handle fruit 4-6
Ton or vegetables 2-3 ton;
2. the present invention is applicable to multiple fruits and vegetables, and vegetables or fruit are flooded the 1-2 branch in dilution
Behind the clock, taking-up is dried;
3. can store or transport better effects if under the cryogenic conditions at normal temperatures after the vanning.
The result of fruit and vegetable fresh-keeping agent practical application of the present invention shows that have following outstanding advantage: raw material sources are rich and easy to get, and method for making is simple, and are cheap.Can be used for multiple fruit and leaf vegetables and melon and fruit class various vegetables such as fragrant Jiao, mango, citrus, pomegranate, apple, pears, peaches and plums, persimmon.After immersion liquid is done, form the semipermeable polymer biomembrane on the pericarp surface, can play the effect of gas fine adjustment, reduce oxygen and enter fruit, suppress physiological and biochemical procedures such as fresh fruit respiration, metabolism, moisture content transpiration preferably, postpone the fruit physiological aging, prolong storage period, and the remarkable efficacy that prevents decayed fruit is arranged, play the comprehensive preservation effect.This product is to the person poultry harmless, and is free from environmental pollution.
Through the various fruit that the present invention handles, the freshness date under 20 ℃ of temperature than undressed, can prolong 1-2 doubly, and freshness date can reach respectively:
Individual month of apple, pomegranate 4-6; Citrus 2-3 month;
Mango, fragrant Jiao, pears, peach, Lee, persimmon etc. 1-2 month;
About 1 month of melon and fruit and fruit vegetables
The present invention prevents that the effect of decayed fruit rate from generally reaching more than 90%, and it is 1: 10～15 that economic benefit is launched the output ratio, the fresh-keeping expense that promptly every input is 1 yuan, can reclaim 10-15 unit profit more.
Embodiment:
Take by weighing raw material by following weight proportion:
Rosin 300 gram shellac 200 gram beeswaxs 500 grams
Probenazole 7 grams (or potassium sorbate or Sodium Benzoate 6 grams)
The production method of above-mentioned each component being made fruit and vegetable fresh-keeping agent of the present invention is:
1. press rosin: shellac: the weight proportion of ethanol=15: 10: 100 is dissolved in rosin and shellac
Ethanolic solution;
2. press beeswax: the weight proportion of caustic soda=100: 1, carry out saponification with conventional method to beeswax;
3. with the weight ratio of 1. and 2. pressing 0.5%, adopt tween to make emulsifying agent, be mixed and made into biology through emulsification
Membrane matrix;
4. add probenazole 7 grams in 3., stirring gets final product.
