Abstract

The present invention discloses a compound preservative for tangerines, and the compound preservative consists of chitosan (concentration, 5-15 g / L), vitamin C (concentration, 2-5.5 g / L), rosemary (concentration, 2-5.5 g / L), citric acid (concentration, 1-2 g / L), calcium propionate (concentration, 1-2 g / L), licorice extract (concentration, 5-8 g / L), phytic acid (mass percent concentration, 0.1-0.3%), carboxymethyl cellulose (concentration, 3.5-5.5 g / L), cordate houttuynia extract (concentration, 4-6 g / L), caulis impatientis extract (concentration, 5-12 g / L) and orange peel extract (concentration, 5-8 g / L), and the compound preservative uses water as solvent. Compared to the traditional chemical preservative, the compound preservative is green and safe, free of toxic side effects on human health, and excellent in preservation effect.

Description

technical field [0001] The invention relates to a composite antistaling agent for tangerines, which belongs to the technical field of fruit preservation. Background technique [0002] Tangerine is a kind of citrus. It tastes sweet like honey, so it is called tangerine. The main components of tangerines are water, protein, fat, carbohydrates, calories, crude fiber, ash, calcium, phosphorus, iron, vitamins, carotene, thiamine, riboflavin, niacin, ascorbic acid, potassium, sodium, Magnesium etc. Eating tangerines often can improve the detoxification effect of the liver, accelerate the conversion of cholesterol, and prevent arteriosclerosis. Tangerine, like many other fruits, is prone to rot due to mechanical damage or pathogen attack during transportation and storage, which is likely to cause large economic losses. Therefore, it is necessary to do a good job in the storage and preservation of tangerines, effectively prolong the storage period of fresh fruits, ensure that t...
