Technique for quick-frozen gingers

Abstract

A technique for quick-frozen gingers includes the processes of ginger selection, desulfurization, sterilization and quick-freezing. The process of ginger selection includes three steps, i.e. material selection, material trimming and winnowing; the process of desulfurization includes three steps, i.e. soaking for desulfurization, cleaning in clean water and sorting; the process of sterilization includes three steps, i.e. sterilization in medical solution, blanching for sterilization and cleaning in normal-temperature water; the process of quick-freezing includes three steps, i.e. cooling in ice water, quick-freezing and making of ice rinds; the gingers are quick-frozen under less than 25 DEG C below and within 15 minutes; in the steps of cooling in ice water and quick-freezing, water temperature is chosen according to the temperature of the quick-freezing tunnel of a fluidized quick-freezing machine, an ice water pond needs to be refrigerated if the temperature of the quick-freezing tunnel is higher than 30 DEG C below, the refrigeration temperature is controlled at 0 DEG C to 5 DEG C, and if the temperature of the quick-freezing tunnel is lower than 30 DEG C below, the ice water pond uses normal-temperature water; in the step of making of ice rinds, the gingers discharged out of the discharge outlet of the quick-freezing tunnel are directly put into a container containing ice water with temperature lower than 4 DEG C for 1 to 3 seconds; and after being packaged, the gingers are stored under the low-temperature condition of less than 18 DEG C below and transported to a point of consumption.

Description

technical field [0001] The invention relates to a process for quick-freezing ginger. Background technique [0002] Ginger is rich in pungent characteristic substances such as gingerol and zingiberene, various nutrients, ginger protease, etc., and has a history of utilization of more than one thousand years in food and medicine. The traditional processing method is only to roughly process it, that is, cleaning, peeling, drying, and making it into flakes or powder. This is neither hygienic nor fresh. Along with socioeconomic development and the raising of people's living standard, the requirement of people's diet, not only will be delicious, but also fresh. Luoping, Yunnan Province, as a geographical indication area of ​​China's small yellow ginger, has unique ginger planting conditions. The low-altitude Nanpanjiang low-heat valley area and the middle and lower reaches of the Jiulong River have a long history of planting and are famous all over the country. Luoping small tu...
