中文摘要：选择喷雾干燥法将丝瓜水制备成干燥的固体粉末,优选喷雾干燥的最佳工艺参数;选择真菌类的白色念珠菌和黑曲霉,分别以丝瓜水粉末1×10-1、1×10-2和1×10-3 g/mL的稀释液,在25、35和45℃下进行抑菌试验。结果表明:喷雾干燥的最佳工艺参数为:进风温度163℃、进料速度20mL/min、喷雾压力70mm Hg、通针频率10次/min;丝瓜水粉末稀释液浓度为1×10-2g/mL以上时对黑曲霉有较强抑制作用,当浓度达1×10-1 g/mL时,抑菌效果非常显著;对白色念珠菌抑制作用相对较弱,浓度达1×10-1 g/mL时,有较强抑制作用。喷雾干燥法制备丝瓜水的固体粉末工艺简单、易行。

外文摘要：Slected spray-drying process for prepareing juice of Towel Gourd into dry powder solid powder,and otimized the best technological parameter for spray drying;Juice of Towel Gourd solid powder dilution of 1×10-1,1×10-2,1×10-3 g/mL concentrations were slected to carry on antifungal activity test against Candida albicans and Aspergillus niger of fungal over 25,35 and 45℃.The results showed that the optimum parameter for spray drying were established as follows：the inlet air temperature was 163℃,the feeding rate was 20 mL/min,the spraying pressure was 70 mm Hg and the Nozzle Cleaning was 10 times/min;Juice of Towel Gourd solid powder dilution concentration above 1×10-2 g/mL had relatively strong inhibitory action against Aspergillus niger,when the concentration was above 1×10-1 g/mL,the bacteriostatic effect was highly significant,and Juice of Towel Gourd solid powder dilution＇s inhibitory actions was relatively weak against Candida albicans,when the concentration was above 1×10-1 g/mL,the inhibiting effect was relatively strong.The process of spray-drying for prepare juice of Towel Gourd＇s solid powder was simple and efficient.
