Preparation method of long-preservation-time water-washable fruit wax

Abstract

The invention relates to a preparation method of long-preservation-time water-washable fruit wax, belonging to the technical field of fruit wax preparation. The preparation method comprises the following steps: preparing water-soluble silicon wax, adding fatty alcohol polyoxyethylene ether and other substances into a palmitic acid-abietic acid mixture to obtain an emulsifier, adding water to form an oil-in-water structure, diluting with water, heating and emulsifying to form an oil-in-water emulsion, mixing the emulsion with vaseline, glycerol and other substances to react, putting the mixture into a refrigerator to form a condensed solid, heating to melt the solid, mixing with the water-soluble silicon wax, adding ammonia water, and uniformly mixing to obtain the long-preservation-time water-washable fruit wax. After being coated on the fruit surface, the fruit wax can have the effects of air permeation, water control, preservation and quality control, can be easily washed by water, is safe with no residues, and thus, has wide application prospects.

Description

technical field [0001] The invention relates to a preparation method of long-lasting fresh-keeping and easy-washing fruit wax, which belongs to the technical field of fruit wax preparation. Background technique [0002] Fruit wax is a lipid secreted by the fruit itself and attached to the epidermis. Its function on the fruit is to prevent pathogens (toxic and harmful substances, bacteria, viruses, etc.) from entering the interior of the fruit and resist the damage caused by environmental changes to the fruit. In recent years, environmental pollution has become more and more serious, and the use of pesticides has increased, causing the original fruit wax on the surface of fruits after picking to cover a layer of harmful substances to the human body, such as pesticide residues, lead-containing substances, sulfur-containing substances and other harmful substances. Therefore, some fruit merchants will wash the fruit before putting the fruit on the market, and the eater will gene...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that traditional palm wax and animal glue wax are not easily soluble in water, difficult to clean when eating, and have poor air permeability, which limits gas exchange inside the fruit, leads to enhanced anaerobic respiration of the fruit, and accelerates volatile odors To solve the problem of material accumulation, a method for preparing long-lasting fresh-keeping and easy-to-wash fruit wax is provided. The invention prepares water-soluble silicone wax, and then adds substances such as fatty alcohol polyoxyethylene ether to the mixture of oleic acid, palmitic acid and abietic acid The prepared emulsifier, after adding water, first forms an oil-in-water structure, then dilutes with water, heats and emulsifies to form an oil-in-water emulsion, mixes the emulsion with vaseline, glycerin and other substances, and puts it in the refrigerator to form coagulation solid, heat and melt it, mix it with water-soluble silicone wax, and add ammonia water, stir and mix evenly to get long-lasting fresh-keeping and easy-to-wash fruit wax. The fruit wax prepared by the present invention can not only play a role in ventilation, control Water, freshness, and quality preservation effects, and easy to clean with water, safe and no residue, has a wide range of application prospects
