Problems solved by technology

After testing, the total number of bacterial colonies in the unwashed black wolfberry is as high as 5.9×10 4 (CFU / g), high degree of bacterial pollution, poor hygiene quality, and harm to human health; the latter is directly washed with water, and the cleaning method is rough, which not only brings secondary pollution but also greatly reduces the content of active ingredients such as anthocyanins, resulting in The quality of the product deteriorates, the curative effect decreases, and the medicinal value is lost

Abstract

The invention discloses a lycium ruthenicum cleaning method.The method includes steps: a, preparing an alcoholic solution with the concentration being higher than 70%v / v and the temperature being -18-25 DEG C as a cleaning solution; b, cleaning lycium ruthenicum in the cleaning solution for 0.5-60min; c, drying the cleaned lycium ruthenicum until the surface of the lycium ruthenicum is free of moisture.The lycium ruthenicum cleaning method is efficient, simple and convenient, silt, and dust and impurities on the surface of the lycium ruthenicum can be removed to remarkably reduce the total plate count of lycium ruthenicum fruits, so that an excellent bactericidal function is achieved; in addition, loss of anthocyanin in a lycium ruthenicum cleaning process can be greatly reduced.The total plate count of the lycium ruthenicum cleaned according to the method is smaller than or equal to 1.6*102(CFU / g), the anthocyanin loss rate is kept below 5%, and the lycium ruthenicum cleaned according to the method is bright in color, free of silt and dust residues, reliable and safe to human bodies and environment friendly.

Description

technical field [0001] The invention relates to a method for cleaning fresh or dried fruit of black wolfberry and belongs to the fields of medicine, health care and food. Background technique [0002] At present, the fruits on the market have more or less residual pollutants. If they are eaten without careful cleaning, the dust, bacteria, pesticides, etc. remaining on the fruits will be brought into the body, especially if they are eaten frequently, which will seriously endanger human health. According to the residues of different pollutants and the characteristics of the fruit itself, it is necessary to choose a suitable cleaning solution. Commonly used cleaning solutions are neutral, weakly alkaline and weakly acidic. For example, flour water can be used to absorb impurities for cleaning bayberry; Bacteria on the surface of fruit, but it will cause changes in the color, aroma and taste of the fruit, and interact with the acid in the fruit to reduce the nutritional value o...
