摘  要:
为充分利用棕色蘑菇漂烫液,采用喷雾干燥制备营养精粉,应用正交实验优化喷雾干燥工艺参数,并分析棕色蘑菇漂烫液喷雾干燥精粉的主要营养成分。结果显示,从抗氧化保留率和得率分析,β-环糊精比麦芽糊精更适宜作棕色蘑菇漂烫液喷雾干燥助干剂;喷雾干燥最佳工艺参数为进风温度150℃、进料总固形物10%、β-环糊精添加率37.50%、雾化压力80MPa,在此条件下精粉得率可达61.36%。营养精粉主要成分为糖类物质和蛋白质,含有17种氨基酸和钙、铁、锌等矿物质,多酚物质达1.25‰。

摘  要:
Effluent from the blanching operation of Agaricus brunescens Peck was spray-dried as a byproduct to recover the nutrients.An orthogonal experiment was conducted to optimize the process,and a chemical analysis performed on the dried powder to evaluate its nutritional value.The results showed that(a)based on the antioxidant retention rate and product yield,β-cyclodextrin was preferable tomaltodextrin as adrying aid;(b)the optimized processing conditions includeda hot air temperature at 150℃,a total solid content of 10%,aβ-cyclodextrin addition of 37.50%,and an atomization pressure at 80 Mpa for the spray dehydration;(c)aproductyieldof 61.36% could be realized;and,(d)the spray-dried powder obtained from the process mainly consisted of carbohydrates and proteins of 17 amino acids,as well as small quantities of calcium,iron andzinc,and 1.25 of polyphenols.
