Abstract

To discuss the feasibility of non-destructive determination method for carrot quality based on the acoustic signal, Pearson correlations between the acoustic eigenvalues and the main compositions of carrot were performed. It indicated that the water content, polysaccharide content and pectin content of carrot were all significantly (P<0.01) correlated with waveform index and sound intensity of acoustic eigenvalues in the time-domain and TE in the range of 2-3, 3-4, 4-5, 5-6, 6-7, 7-8 and 8-9 kHz. Through PCA analysis, 9 eigenvalues with good correlation can be reduced into two principal component factors. The acoustic signals knocked by the self-made signal collection platform could be a new nondestructive testing technology for quality evaluation of carrots. These results will provide essential information to determine the food attributes of agro-products through acoustic signals.
