中文摘要:

      核桃品种多样、食味香纯、口感细腻、出油率高, 能够健脑益智、补气养血、润燥化痰、防癌抗癌, 是我国栽培历史悠久、营养价值丰富的农产品, 有着“万岁子”“长寿果”的美誉。但核桃在生长和处理过程中, 受产地、品种、气候、储存环境、处理设备等因素的影响, 容易造成核桃品质不一, 甚至出现霉烂、虫害和变质等现象, 影响核桃品质和后续深加工。为保证核桃产品质量, 需对核桃进行检测和分级, 而无损检测技术可以在不破坏核桃本身的情况下对其进行高效快速的检测, 避免检测过程中样品成分和营养损失, 因此被广泛应用在核桃检测中。本文总结了3种无损检测技术, 对比分析了3种无损检测技术的优劣, 并从产地品种检测、内部品质检测、外部缺陷检测、异物分类检测4个方面总结了无损检测在核桃相关检测中的应用研究进展, 提出了核桃相关检测中存在的问题, 并对核桃无损检测研究的发展前景进行了展望, 为无损检测技术在核桃相关领域应用提供了参考。

英文摘要:

      Walnut has a variety of varieties, pure taste, delicate taste, high oil yield, can strengthen the brain and intelligence, replenish qi and nourish blood, moisturize phlegm, prevent cancer and fight cancer, is an agricultural product with a long history of cultivation and rich nutritional value in China, and has the reputation of “long live son” and “longevity fruit”. However, in the process of growth and processing of walnuts, affected by factors such as origin, variety, climate, storage environment, processing equipment and other factors, it is easy to cause different walnut quality, and even mildew, pests and deterioration, etc., affecting walnut quality and subsequent deep processing. In order to ensure the quality of walnut products, walnuts need to be detected and graded, and non-destructive testing technology can detect them efficiently and quickly without damaging the walnuts themselves, avoiding sample composition and nutrient loss during the testing process, so it is widely used in walnut testing. This paper summarized the three non-destructive testing technologies, compared and analyzed the advantages and disadvantages of 3 kinds of non-destructive testing technologies, summarized the application research progress of non-destructive testing in walnut-related testing from four aspects: Origin variety detection, internal quality testing, external defect detection and foreign body classification detection, puts forward the problems existing in walnut-related testing, and looks forward to the development prospects of walnut nondestructive testing research, providing a reference for the application of non-destructive testing technology in walnut related fields.
