摘要: 对不同熬制时间的“佛跳墙”高汤进行感官评定,并测定高汤中的蛋白质、脂肪、游离氨基酸和游离核苷酸的含量,以考察高汤熬制过程中营养与风味成分的变化.结果表明:当熬制到第10 h时,高汤的感官评分最高,为92分,此时高汤中的蛋白质和脂肪的质量分数也最高,分别为39.2%和40.9%;从高汤中共检测出21种游离氨基酸和6种游离核苷酸,高汤中呈鲜味的游离氨基酸和游离核苷酸的质量浓度相对稳定.Abstract: The sensory evaluation of "Fotiaoqiang" soup-stock was investigated at different boiling time.The contents of protein,lipid,free amino acid and free nucleotide were determined to discover the nutritional and flavor changes during soup-stock slow boiling.The results showed that the highest sensory evaluation score was 92 when the soup-stock boiling time was the 10 th hour with the highest protein and lipid concentration of 39.2% and 40.9% respectively.21 kinds of free amino acid and 6 kinds of free nucleotide were detected in the soup-stock and the concentration of free amino acid and free nucleotide representing umami taste was relatively stable.
