摘要
以香菇、北虫草、黄秋葵和山药为试材,研究热风干燥和喷雾干燥两种干燥制粉方式对果蔬粉品质的影响,以果蔬粉可溶性固形物含量、溶解性、堆密度以及特征营养指标多糖和总黄酮含量为指标进行检测和分析评价。试验结果表明,喷雾干燥得到的果蔬粉溶解性和堆密度指标优于热风干燥的,两种干燥方式对特征成分多糖没有显著性影响,喷雾干燥得到的黄秋葵粉黄酮含量高于热风干燥的。综合考虑,四种物料均为喷雾干燥制粉的效果优于热风干燥。
Taking Letinous edodes, cordyceps, okra and yam powder as experimental materials, this paper studied the effects of two drying methods on hot pepper drying and spray drying on the quality of fruits and vegetables. The soluble solids content, solubility, bulk density, and the content of polysaccharides and total flavonoids in the nutritional index were determined and analyzed. The results showed that the solubility and density of spray dry powder were better than that of hot air dry powder. The two drying methods had no significant effect on polysaccharides, and the flavonoids content in spray drying okra powder was higher than that in hot air drying powder. The effect of spray drying was better than that of hot air drying for these four different materials.
