Fresh-keeping film coating fruit wax for fruits and vegetables

Abstract

The invention discloses fresh-keeping film coating fruit wax for fruits and vegetables, which relates to a fresh-keeping agent for fruits and vegetables. The fresh-keeping film coating fruit wax is prepared by the following steps of: firstly, mixing the following components in percentage by weight: 11.38 percent of red lac, 2.35 percent of morpholine, 0.8 percent of ammonium hydroxide, 1.5 percent of medicinal propanediol, 6.03 percent of modified resin and 1.02 percent of isolated soy protein; secondly, after the components are mixed, emulsifying the mixture for 15 minutes, heating the mixture to 70 DEG C, putting the mixture into a stirrer, stirring the mixture at the speed of between 780 and 1,000r/min for 30 minutes, and cooling the mixture to 40 DEG C; and finally, adding 0.09 percent of medicinal propyl p-hydroxybenzoate into the mixture in a weight ratio, and dispersing the mixture for 40 minutes to obtain the fresh-keeping film coating fruit wax for the fruits and vegetables. The fresh-keeping film coating fruit wax for the fruits and vegetables has the advantages of high drying speed, good film forming property, long bright duration, good fresh-keeping effect and no harm to the human body.

Description

technical field [0001] The invention relates to a fresh-keeping agent for fruits and vegetables, in particular to fruit wax coated with a fresh-keeping film for fruits and vegetables. Background technique [0002] Fruit wax is also known as a fruit coating agent, which covers the surface of fruits to play the role of antisepsis, insurance, quality preservation, inhibition of water evaporation, prevention of microbial invasion, increase of fruit surface finish and brightness, and prolong storage. [0003] In China, the research on fruit wax mainly focuses on two aspects, one is a low-molecular chemical wax represented by a polyethylene liquid film, and the other is a high-molecular natural wax represented by "chitin". But these two kinds of waxes have deficiencies, one is that the color and luster and brightness after processing the fruit are not good, and the function of improving the sensory quality of the fruit is relatively poor; the other is that the dosage form is eithe...

Problems solved by technology

But these two kinds of waxes have deficiencies, one is that the color and luster and brightness after processing the fruit are not good, and the function of improving the sensory quality of the fruit is poor; the other is that the dosage form is either too viscous or too thin, which is not suitable for waxing equipment. use, not easy to promote
