Abstract
The invention discloses a method for preparing fresh-keeping film coating fruit wax for fruits and vegetables, and relates to a fresh-keeping agent for fruits and vegetables. The method for preparing the fruit wax mainly comprises the following steps of: selecting morpholine and ammonia hydroxide as raw materials, adding water into the raw materials, fully mixing the raw materials, starting a stirrer and heating the mixture at the same time; adding modified resin and red lac into the mixture after the mixture is fully heated and stirred uniformly, and stirring the mixture to form solution; adding isolated soy protein into the solution, and stirring the solution; adding medicinal propanediol and medicinal propyl p-hydroxybenzoate into the solution, lightly stirring the solution, shutting down the stirrer after the solution is fully mixed, and dispersing the solution for 40 minutes; adding fatty acid and surfactant into the mixed solution, and lightly stirring the solution; adding isopropanol, antifoaming agent and a proper amount of water into the stirred solution; and lightly stirring the solution and then cooling the solution to 37.8 DEG C to form fruit wax. The method has the advantages that: the additive and the solution can fully dissolve the acid washing substances such as resin and red lac during preparation, and meanwhile the whole process is implemented in a closed pressure container, so the method does not discharge ammonia; and the whole preparation process for preparing the fruit wax product does not generate other side products, so the method is convenient for popularization and use.
Description
Technical field
The present invention relates to fruit and vegetable fresh-keeping agent, specifically is a kind of preparation method of fresh-keeping film coating fruit wax for fruits and vegetables.
Background technology
Fruit wax also b referred to as the fruit fruit glaze agent, is coated on fruit surface, play anticorrosion, insure, guarantee the quality, suppress water evaporates, prevent microbiological attack, increase fruit surface fineness and effects such as brightness, prolongation holder.
At home, mainly concentrate on two aspects relevant for the research of fruit wax, a kind of is that a polyethylene liquid film is the degraded wax of representative, and another kind is to be the macromolecule native paraffin of representative with " chitin ".But these two kinds of waxes exist deficiency, and the first is handled color and luster after the fruit, brightness is not good enough, and the function of improving the fruit aesthetic quality is relatively poor; It two is formulation or thickness too, or too rare, is not suitable for using on waxing equipment, is difficult for promoting.Carrying is not the generation that can be accompanied by ammonia in the preparation process of fruit wax at present, causes the generation of some byproducts, thus the purity that influence fruit wax is made.
Summary of the invention
Technical problem solved by the invention is to provide a kind of preparation method who processes fresh-keeping film coating fruit wax for fruits and vegetables.
Technical problem solved by the invention realizes by the following technical solutions:
A kind of preparation method of fresh-keeping film coating fruit wax for fruits and vegetables,
It is characterized in that: the step for preparing this fruit wax mainly comprises,
1, raw material selection morpholine and aqua ammonia add the laggard row of entry and fully mix, and open mixer and heat simultaneously;
2, fully heating and stir back adding modified resin and lac, stir into the solution shape;
3, add soybean protein isolate in the solution, and stir;
4, in solution, adding be used as medicine grade propylene glycol and medicine level propylparaben, stirring gently, closing and close mixer after the abundant mixing and disperseed 40 minutes;
5, adding aliphatic acid and surfactant in the above-mentioned mixed solution, and stirring gently;
6, add isopropyl alcohol and antifoaming agent in the solution after stirring, and add an amount of water;
7, be cooled to 37.8 ℃ after the stirring gently, form fruit wax;
8, the fruit wax that will make imports in the cleaning container and gets final product.
The weight partition ratio of described lac, morpholine, ammonium hydroxide, medicine grade propylene glycol, modified resin, soybean protein isolate and the medicine level P-hydroxybenzoic acid third fat component is respectively
Lac 11.38%
Morpholine 2.35%
Ammonium hydroxide 0.8%
Medicine grade propylene glycol 1.5%
Modified resin 6.03%
Soybean protein isolate 1.02%
Medicine level P-hydroxybenzoic acid third fat 0.09%.
The beneficial effect that the present invention has is additive (morpholine and aqua ammonia) in the preparation process and solution these pickling materials of dissolving resin lac fully, in airtight pressure vessel, carry out in the whole process simultaneously, therefore there is not the discharging of ammonia, and be shaped in the whole process of preparation fruit wax product appearance, do not have the generation of other byproduct, be convenient to promote and use.
The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the present invention.
A kind of preparation method of fresh-keeping film coating fruit wax for fruits and vegetables, key step comprises:
1, raw material selection morpholine and aqua ammonia add the laggard row of entry and fully mix, and open mixer and heat simultaneously;
2, fully heating and stir back adding modified resin and lac, stir into the solution shape;
3, add soybean protein isolate in the solution, and stir;
4, in solution, adding be used as medicine grade propylene glycol and medicine level propylparaben, stirring gently, after closing mixer, disperseing 40 minutes;
5, adding aliphatic acid and surfactant in the above-mentioned mixed solution, and stirring gently;
6, add isopropyl alcohol and antifoaming agent in the solution after stirring, and add an amount of water;
7, be cooled to 37.8 ℃ after the stirring gently, form fruit wax;
8, the fruit wax that will make imports in the cleaning container and gets final product.
Wherein the weight partition ratio of raw material lac, morpholine, ammonium hydroxide, medicine grade propylene glycol, modified resin, soybean protein isolate and the medicine level P-hydroxybenzoic acid third fat component of each step adding is respectively
