Nondestructive Detection of Total Soluble Solids and Total Acids in Navel Orange by Ultrasound

  • 摘要: 目的:使用超声波无损检测技术对脐橙的主要内部品质参数进行检测。方法:在搭建完超声波无损检测平台后,将同一批脐橙分为实验组与对照组,对两组分别进行为期20 d的检测,每次检测间隔24 h。根据检测结果,建立超声波特征参数与脐橙内部品质参数之间的关系并检验。结果:建立了超声波衰减系数(Attenuation coefficient,A)与脐橙可溶性固形物(Total soluble solid,TSS)之间的拟合方程:TSS=2.512A3-11.78A2+23.03A-2.805,R2=0.9982,RSME=0.1377,预测相对误差σ<5%;超声波衰减系数与脐橙总酸(Total acid,TA)之间的拟合方程:TA=-0.5219A3+2.073A2-2.724A+1.716,R2=0.9735,RSME=0.0131,预测相对误差σ<5%。结论:超声波衰减系数对脐橙内部品质的变化敏感,超声波无损检测技术用于脐橙内部品质检测是可行的。

     

    Abstract: Objective:To detect the main internal quality parameters of navel orange by ultrasonic nondestructive testing technology.Methods:After the establishment of ultrasonic nondestructive testing platform,the same batch of navel oranges were divided into experimental group and control group. The two groups were tested for 20 days,with 24 h interval each time. According to the test results,the relationship between ultrasonic characteristic parameters and internal quality parameters of navel orange was established and tested.Results:The fitting equation between ultrasonic attenuation coefficient(A)and total solid(TSS)of navel orange was established:TSS=2.512A3-11.78A2+23.03A-2.805,R2=0.9982,RSME=0.1377,prediction relative error σ<5%. The fitting equation between ultrasonic attenuation coefficient and total acid(TA)of navel orange was established:TA=-0.5219A3+2.073A2-2.724A+1.716,R2=0.9735,RSME=0.0131,prediction relative error σ<5%. Conclusion:The attenuation coefficient of ultrasound is sensitive to the change of internal quality of navel orange. It is feasible to use ultrasonic nondestructive testing technology to detect the internal quality of navel orange.
