Problems solved by technology

The traditional quick-freezing processing method has always used heating and blanching to sterilize and inactivate the activity of enzymes to prevent enzymatic browning, but experiments have shown that the viscosity of yam mucilage will decrease with the increase of heating time, and with With the continuation of the heating time, the irreversible viscosity decreases, indicating that the mucus complex begins to decompose, which reduces the commodity value of yam

Abstract

The making process of quick-frozen Chinese yam includes soaking in disinfectant liquid to kill bacteria, peeling, cutting into blocks, soaking in color protecting liquid for maintaining color, soaking in disinfectant liquid to kill bacteria again, quick freezing, coating with ice and further freezing. The present invention has the advantages of no decrease in Chinese yam grume viscosity, no change in color and high bactericidal effect.

Description

technical field [0001] The invention belongs to a processing method of yam, in particular to a preparation method of quick-frozen yam. Background technique [0002] Yam has extremely high health value. It can invigorate the spleen, nourish the lungs, strengthen the kidney, and benefit the essence. According to the "Book of Materia Medica": "Yam can be filled with essence by the kidney, and when the essence is set, it will strengthen the yin, brighten the eyes, and deafen the ears." It has been a health food with the same source of medicine and food since ancient times. The mucilage in yam is a complex of polysaccharides and proteins. According to literature reports, the protein in the complex accounts for 47.6%, and the polysaccharide accounts for 62.4%. Recent studies have proved that the mucilage It can adjust the immune coefficient of the human body and enhance resistance. It not only has rich nutritional value, but also has anti-virus, anti-aging, a...
