鸭骨泥酶解液喷雾干燥工艺研究

The studies of spray drying on duck bone mud hydrolysate

利用实验型喷雾干燥机对鸭骨泥酶解液进行喷雾干燥,为制备热反应型肉味香精提供原料,主要研究了β-环糊精浓度、进料速度和进风温度对鸭骨泥酶解液喷雾干燥效果的影响,并对鸭骨泥酶解液喷雾干燥粉的氨基酸组成进行了测定。实验结果表明:鸭骨泥酶解液的最佳喷雾干燥条件为β-环糊精浓度2 g/dL,进料速度0.278 mL/s,进风温度230℃,在此最佳喷雾干燥条件下鸭骨泥酶解液喷雾干燥粉感官评分为9.3,水分含量0.87%,溶解度75.68 g/100 g,润湿性为30 s,含有17种氨基酸,其中必需氨基酸7种,占氨基酸总量的48.66%。

Duck bone mud hydrolysate was dried by experimental spray dryer for supplying materials to prepare heat reaction meat flavor.Influence of β-cyclodextrin concentration,feed rate and inlet temperature on spray drying effect of duck bone mud hydrolysate was studied and its amino acid composition was determined in this article.The results showed that the best preparation of process parameters of duck bone mud hydrolysate was β-cyclodextrin concentration 2 g/dL,feed rate 0.278 mL/s,inlet temperature 230 ℃.In the best of the preparation process parameters,sense organ evaluates of spray drying powder of duck bone mud hydrolysate was 9.3,water content 0.87%,solubility 75.68 g/100 g,wettability 30 s,containing 17 kinds amino acid,7 essential amino acids in it and 48.66% in total amino acids.
