Non-destructive Detection of Different Maturity Agaricus Bisporus Firmness Based on Raman Spectroscopy
摘要
Abstract
The firmness model of agaricus bisporus pileus was established by using Raman spectros-copy combined with chemometric methods. With the help of PinPoniterTM portable Raman spectrome-ter, rapid and nondestructive for agaricus bisporus firmness prediction was studied. According to the average pileus diameter, the samples with pileus diameter of 2-3 cm were classified as classⅠma-turity, 3-5 cm as class Ⅱ. 65 samples of each type were used to collect spectrum and measure firmness. The data were pretreated by four methods of 1st derivatives, 2nd derivatives, standard normal variate and baseline, respectively. The model of partial least square was established. The best effect of both model was 1st derivative, but the correlation coefficient ( Rp ) and root mean square error of prediction (RMSEP) of Ⅰ were 0. 887 and 0. 444, respectively. Class Ⅱ��s Rp and RMSEP were 0. 896 and 0. 435, respectively. The results show that the prediction of classⅡmush-room firmness is more accurate than classⅠ. Under the same conditions, the more feasible storage measures can be implemented for classⅡmushroom, so we shall try to capture the pileus diameter of 3-5 cm of agaricus bisporus for production, processing and daily sales.关键词
