Embodiment Construction

[0053] When the present invention detects the wall breaking rate of the ganoderma lucidum spore powder to be tested, a near-infrared spectrometer is first used to collect the near-infrared spectrum data of the sample to be tested; 9411.6-5446.4cm after treatment -1 and 4613.2-4243cm -1 For the data in the two spectral intervals, under the condition that the number of factors is 10, the wall breaking rate prediction model established based on the partial least squares regression method is used to detect the wall breaking rate of the sample to be tested.

[0054] The prediction model of the broken wall rate established is:

[0055] Y=A 0 +A 1 ×X 1 +A 2 ×X 2 +A 3 ×X 3 +A 4 ×X 4 +A 5 ×X 5 +A 6 ×X 6 +A 7 ×X 7 +A 8 ×X 8 +A 9 ×X 9 +A 10 ×X 10 (1)

[0056] In formula (1): Y is the breaking rate, A 0 、A 1 ,...,A 10 are constants, X 1 is the score of the first factor after the dimensionality reduction of spectral data by principal component analysis, X 2 is t...

Abstract

The invention provides a method for rapidly and nondestructively detecting the sporoderm-breaking rate of reishi shell-broken spore powder. The method comprises the steps of acquiring near infrared spectrum data of a sample to be detected by a near infrared spectrograph, and carrying out multiplicative scatter correction pretreatment on the near infrared spectrum data of the sample to be detected; selecting the pretreated data in two spectral ranges of 9411.6-5446.4cm<-1> and 4613.2-4243cm<-1>, and detecting the sporoderm-breaking rate of the sample to be detected by a sporoderm-broken rate prediction model established according to a partial least squares regression method under the condition that the factor value is 10. The method has the advantages of being rapid, accurate, nondestructive and low in cost, and is beneficial to popularization, and by using the method, the problem of quality monitoring of the sporoderm-breaking rate of the reishi shell-broken spore powder can be effectively solved.

Description

technical field [0001] The invention relates to a method for detecting the wall-breaking rate of fungal spores, in particular to a method for rapidly and non-destructively detecting the wall-breaking rate of wall-broken ganoderma lucidum spore powder. Background technique [0002] Ganoderma lucidum spore powder is the extremely tiny oval reproductive cells ejected from the gills of Ganoderma lucidum during the growth and maturity stage, that is, the seeds of Ganoderma lucidum. It condenses the essence of Ganoderma lucidum, and has all the genetic material and health care functions of Ganoderma lucidum. The shell of Ganoderma lucidum spore powder includes two layers of spore walls made of very hard chitin cellulose; This makes it difficult for the effective substances in the Ganoderma lucidum spore powder to be absorbed by the human body. After the spore wall of Ganoderma lucidum spore powder is broken or eliminated through artificial mechanical, physical and chemical metho...
