鲍鱼冷风干燥和自然晾晒试验的比较分析
Comparation and analysis of cold-blast air drying and natural drying of abalone
摘要
Abstract
Fresh abalones were dried in cold-blast air and natural air in the laboratory, the drying rate, color, content of total polysaccharide and acidic polysaccharide, and changes in microstructure were investigated and analyzed. Both of the two methods were undergoing a short-time rising drying rate period first, then the drying rate decreased. The results showed that; when the moisture content dropped from 238% to 16% , the time of cold-blast air drying needed was 122 hours, which was 70% of natural drying. The content of total polysaccharide and acidic polysaccharide in abalones of the two drying methods were increased significantly. Abalones dried in natural air and cold-blast air showed dark yellow and brilliant yellow respectively, and the light permeability of cold-blast air dried abalone was better than that of natural dried abalone obviously. The microstructures had little differences, muscle fibre of natural dried abalone shrank equably, and there were no holes appeared, while fibre of the cold-blast air dried abalone bent a little, and there are many holes appeared. Compared with natural drying, cold-blast air drying is a preferable method, because it had a short drying time, the drying process was easy to control, quality and sanitary conditions were better.关键词
