Preservative fruit wax containing bleached lac as well as preparation method and application thereof

Abstract

The invention provides preservative fruit wax containing bleached lac as well as a preparation method and application thereof. The preservative fruit wax for fruits and vegetables is prepared by mixing bleached lac, glycerol, sodium hydroxide, oleic oil, morpholine, ammonia water, hydroxypropyl methyl cellulose and deionized water in a certain ratio and heating the mixture. By using the fruit wax to treat fruits and vegetables, fruit wax after film forming is not whitening, water-holding and preservative, good in flowability of fruit wax and hard to crust. Accumulation of substances with peculiar smells such as ethanol and acetaldehyde can be obviously reduced, the performance of prolonging the shelf life in quality maintaining aspect is superior to that of existing imported fruit wax, and the preservative fruit wax meets the environment-friendly safe demand of foods and mechanical waxing.
