Problems solved by technology

[0002] In the prior art, for the air drying of wolfberry, chemical preparations such as sodium bicarbonate, soda ash, sodium bisulfite or sulfur are usually used to shorten the drying time, maintain the color of dried fruit of wolfberry and prolong the preservation time, but the above chemical preparations are used in practice. There are different problems in the process of use: for example, sodium bicarbonate will remain on the surface of dried wolfberry fruit, and the drying time of wolfberry is relatively long, usually about 7 to 8 days; sodium bisulfite is a carcinogen, which has been banned by the country at present; The residual amount of sulfur is higher, and the dried fruit of wolfberry is bright and unnatural

Abstract

The invention relates to a color retention drying agent specially used for wolfberry and is characterized in that the color retention drying agent is composed of edible sodium carbonate, sodium citrate, sodium erythorbate and potassium sorbate according to the mix ratio by weight of 1000: 2-10:1-8:0.5-6. The selected edible sodium carbonate of the wolfberry special color retention drying agent can resolve a waxy layer on the surface of a barbary wolfberry fruit and rapidly absorb the water, thus shortening the drying time, the sodium citrate can remove the pesticide residues, retain the original taste of the barbary wolfberry fruit and ensure the surface of the barbary wolfberry fruit to be round; the sodium erythorbate can prolong the guarantee period; the potassium sorbate can play the roles of color retention, color enhancement and fresh preservation, and the preparations can not damage the nutritious ingredients of the barbary wolfberry fruit. The color retention drying agent combines the chemical preparations, thereby shortening the drying time of the barbary wolfberry fruit, prolonging the fresh preservation time and the storage time and not damaging the nutritious ingredients of the barbary wolfberry dry fruit, and the barbary wolfberry dry fruit has good color, uniform color, no oily matters, no molds, no odor and no residues.
