摘要
不同温度处理对杏鲍菇品质的影响进行主成分分析与综合评价。结果表明:9个生理生化检测指标进行主成分分析可简化为2个主成分,累积方差贡献率为89.308%,能够较好地反映原始数据的信息;综合主成分分析显示,不同温度贮藏杏鲍菇综合品质从高到低的排列顺序为2℃>4℃>6℃>8℃>10℃>12℃,由此可见,低温处理有利于杏鲍菇贮藏保鲜,而文中所建立的综合评价方法可以用于食用菌产品品质的量化和排序。
Effect of temperature on the quality was analyzed by using SPSS software. The results showed that 9traits were simplified into 2 principal components,which accounted for 89. 308% of total variation. Comprehensive principal component analysis showed that the order of comprehensive quality of P. eryngii under different temperature storage was 2 ℃ 4 ℃ 6 ℃ 8 ℃ 10 ℃ 12 ℃. Therefore,the low temperature helps the storage and preservation. The method established in this paper could provide a scientific and intuitive evaluation on the quantify of mushroom product.
