Method for making dried Chinese wolfberry fruits and capable of removing pesticide residues

Abstract

The invention discloses a method for making dried Chinese wolfberry fruits and capable of removing pesticide residues, and aims to solve the technical problem of high technological cost for degradingthe pesticide residues in the course of making the dried Chinese wolfberry fruits in the prior art. The method comprises the following steps of (1) performing picking: by adopting an artificially picking method, picking fresh Chinese wolfberry fruits from plants; (2) performing cleaning with water: flushing the picked fresh fruits with clean water, and washing away dirt on the surfaces of the fresh fruits; (3) performing soaking in edible alcohol: soaking the fresh fruits washed with water in the edible alcohol; (4) performing fumigation and steaming with yellow wine: performing fumigation andsteaming on the fresh fruits treated in the step (3) with yellow wine; and (5) drying: a, performing stirring with alkali: adding dietary alkali, uniformly mixing the fresh fruits with the dietary alkali, and performing standing for 30-60 min; and b, performing airing: uniformly and flatly spreading the treated fresh fruits on a fruit rack, and performing airing until the moisture content of thefresh fruits is reduced to 12% or below. Compared with the prior art, the method disclosed by the invention has the advantages that equipment investment is reduced, and the dried product making cost is reduced.

Description

Technical field [0001] The invention relates to the technical field of wolfberry processing, in particular to a method for preparing dried wolfberry to remove pesticide residues. Background technique [0002] Lycium barbarum is a kind of perennial shrub economic crop that is drought-tolerant, barren-tolerant, and salt-tolerant. The unique geographical advantage of Zhongning area in Ningxia makes the lycium barbarum produced there have extremely high nutritional value, containing 18 kinds of amino acids, carotene and calcium. , Iron, phosphorus, selenium and other trace elements. The fresh fruit of Lycium barbarum is a berry with a water content of 75% to 80%. The fruit is red, and the surface is covered with wax. Because the fresh fruit of Lycium barbarum is not resistant to preservation, it often needs to be made into dried fruit. The water content of dried fruit is less than 12%. Not soft or crispy. [0003] In the process of planting wolfberry, in order to prevent pests and di...
