Chinese wolfberry drying agent and application method thereof

Abstract

The invention discloses a Chinese wolfberry drying agent and an application method thereof. The Chinese wolfberry drying agent includes an agent A and an agent B, wherein the agent A is sodium carbonate or potassium carbonate, and the agent B is a mixture consisting of the following components by mass percentage: 10 to 40 percent of sodium D-isoascorbate, 10 to 40 percent of sodium ethyl p-hydroxybenzoate, and 20 to 80 percent of sodium propyl p-hydroxybenzoate. When being used for processing fresh Chinese wolfberry fruits, the Chinese wolfberry drying agent provided by the invention can reduce the Chinese wolfberry mildew rate by 80 percent, increase the Chinese wolfberry red fruit rate up to above 90 percent, shorten the drying time, avoid the problem that excessive SO2 (sulfur dioxide) is easily caused by the application of sodium pyrosulfite, improve the Chinese wolfberry drying efficiency and quality, ensure the Chinese wolfberry quality, and meet the needs of Chinese wolfberry growers for new technologies. Therefore, the Chinese wolfberry drying agent has broad prospects.

Description

technical field [0001] The invention relates to the technical field of drying and fresh-keeping of fruits and vegetables, in particular to a drying agent for dried wolfberry fruit and a method for using the same. Background technique [0002] Lycium barbarum is a special economic plant resource in my country. It is not only a traditional precious Chinese medicinal material, but also a functional specialty resource of "medicine and food from the same source". It is a traditional agricultural product for exporting foreign exchange in my country. In recent years, centering on Ningxia, it has radiated to 12 provinces, municipalities and autonomous regions including Xinjiang, Inner Mongolia, Qinghai, and Gansu. By 2013, the national planting area had exceeded 1.7 million mu, with a total output of 200,000 tons and a total output value of about 10 billion yuan. , significant economic benefits. [0003] More than 90% of goji berries are sold as dried fruit in domestic and foreign ...

AI Technical Summary

Problems solved by technology

The traditional drying method of fresh fruit dehydration is sunlight drying, which cannot meet the large-scale production of wolfberry planting in large areas, and the quality is unstable and the food safety is not high

[0004] At present, the latest dehydration and drying of wolfberry fresh fruit is realized by using a drying agent composed of various chemical substances, such as the Chinese patent "Lycium barbarum color protection dewaxing agent" (CN200610163494.0), "A wolfberry color protection dewaxing agent "(CN200610163494.0), "Lycium barbarum special color-protecting drying agent" (CN200810133860.7), "Lycium barbarum fresh fruit dehydration-accelerating processing aid" (CN201110167478.X), "A wolfberry-accelerating color-protecting agent and its use Method" (Document No.: A23B7 / 022Yk201010161692), "Using Animal and Vegetable Oil to Prepare Grape or Goji Berry Drying Agent" (CN01124670.7), etc. These technologies all play a positive role in the dewaxing and drying of goji berry fresh fruit, but there is a need for Perfect places, such as using only sodium carbonate to dry for a long time, using sodium metabisulfite is easy to cause SO 2 Exceeding the standard, the drying efficiency is not high, the quality of wolfberry is declining, the incidence of mildew in wolfberry is high, etc.
