Nondestructive quality evaluation of agro-products using acoustic vibration methods—A review

ABSTRACT

Quality evaluation of agro-products is quite important because it is the basis for growers, distributers, and consumers. Various novel and emerging nondestructive methods were proposed for quality evaluation of agro-products. The acoustic vibration method is one of the major nondestructive methods for agro-products in pre- and postharvest research and industrial practice. Acoustic vibration characteristics of agro-products can be used for texture evaluation, prediction of optimum eating and harvest ripeness, ripeness classification and defect detection. Generally, there are three parts in the process of acoustic vibration method, including the excitation module, signal acquisition module, and signal-processing module. The impact method and forced method are two excitation methods in the excitation module, and there are contact and noncontact sensors for vibration measurement in the signal acquisition module. Noncontact measurement can meet the requirement of rapid and nondestructive measurement, especially for the on-line detection. However, increasing demand for accurate and cost-effective measurement remains a challenge in the agro-products industry. Comparison of acoustic vibration methods and traditional destructive methods was also discussed, which helps to give a more comprehensive assessment for the acoustic vibration method.     

欧盟农产品技术性贸易措施研究

欧盟是我国农产品出口的重要目标市场。近年来,食品安全方面的技术性贸易壁垒成为我国农食产品扩大向欧盟出口的重要障碍。本文从欧盟农产品生产和贸易概况、欧盟农产品技术性贸易措施管理体系、欧盟农产品TBT/SPS通报情况、欧盟召回我国出口农产品情况、欧盟农产品技术性贸易措施实施特点五个方面系统地研究了欧盟技术性贸易措施体系,并针对应对欧盟农产品技术性贸易壁垒提出了对策建议。
