The Application of Optical Nondestructive Testing for Fresh Berry Fruits

Berry fruits are highly nutritious and possess therapeutic properties, making them popular in various markets including fresh fruit, food, beauty, medical, and health. As people's quality of life continues to improve, the demand for berry fruits is increasing. As a result, farmers must prioritize the quality of berry fruits while also increasing production. In the realm of quality control, berry fruit detection holds great significance. However, traditional detection methods are plagued with major drawbacks such as destructiveness, high cost, and a long detection time. Fortunately, nondestructive testing technology has rapidly developed due to its nondamaging, efficient, and versatile advantages. This method can complete various detection projects and meet the diverse detection requirements of orchard supervision. This paper provides a review of the use of nondestructive testing technology in various types of berry fruits and highlights the progress made in optical nondestructive testing technology for identifying these fruits, as well as detecting their external and internal quality. This article summarizes and analyzes the challenges encountered by nondestructive testing in the same field of berry fruits and explores the potential development directions of nondestructive testing technology in the field. The findings of the study can offer valuable insights and reference for the intelligent management of berry orchards and the enhancement of the berry market system.
