中文摘要: 该研究以白熟期婆枣为原材料,研究日光干燥(sunlight drying,SD)、热风干燥(hot air drying,HAD)、二流体喷雾干燥(two-fluid spray drying,TSD)、真空冷冻干燥(vacuum freeze drying,VFD)对枣粉物理性质、营养品质及抗氧化活性的影响。采用主成分分析及聚类分析,将不同干燥方式枣粉的理化指标分为3 个主成分,根据综合得分进行排序,结果为VFD>HAD>SD>TSD。根据不同干燥方式枣粉的理化指标,将4 种干燥方式聚为2 类,HAD、SD、TSD 聚为第一类,VFD 聚为第二类。
Abstract:The fruits of the jujube variety 'Pozao' at the white ripening stage were treated with sunlight drying(SD),hot air drying(HAD),two-fluid spray drying(TSD),and vacuum freeze drying(VFD),and then the physical properties,nutrient content,and antioxidant activities of jujube powder were determined. The principal component analysis and cluster analysis were performed,and the physical and chemical properties of jujube powder prepared with different drying methods were attributed to three principal components.The comprehensive score of the jujube powder followed the trend of VFD>HAD>SD>TSD. According to the physical and chemical properties of jujube powder,the four drying methods were clustered into two categories,with HAD,SD,and TSD in the first category and VFD in the second category.
