摘　　要：生物散斑激光技术是通过He-Ne激光照射在样品表面,利用样品对光散射能力不同形成不同的散斑图案,从而实现对样品品质、营养成分的定性、定量分析的光谱学技术。散斑活性的大小与样品生化反应过程中的物理特性、化学成分及内部品质有关。该技术具有对样品破坏性小、检测时间短、可应用于农畜产品成熟度监测、新鲜度监测以及品质检测多方面的优势,但是其稳定性差、穿透深度浅也限制了它的应用。本文简述了生物散斑激光技术的特点,重点综述了其无损检测原理和在食品成熟度、新鲜度、品质检测中应用效果的研究进展,展望了其在食品检测方面的应用潜力和局限性,旨为此技术在食品无损检测领域应用提供理论和技术支持。Biospeckle laser technique is a spectroscopy technology that uses He-Ne laser to irradiate the surface of the sample,forming different speckle patterns due to the different light scattering capabilities of the sample,so as to realize the qualitative and quantitative analysis of sample quality and nutrients.The size of the biologic activity is related to the physical characteristics,chemical composition and internal quality of the sample during the biochemical reaction.This technique has the advantages of small damage to samples,short detection time,and can be applied to the aging detection,freshness detection and quality detection of agricultural and livestock products,but its poor stability and shallow penetration depth also limit its application.This article briefly describes the characteristics of biospeckle laser technique,focusing on its non-destructive detection principles and the research progress of its application effects in food aging,freshness,and quality detection,and prospects its application potential and limitations in food detection.It aims to provide theoretical and technical support for the application of this technique in the field of food non-destructive detection.
