多光谱成像技术在食品营养品质检测方面的应用进展

Application Progress of Multispectral Imaging for Food Nutritional Quality Detection

食品营养品质是食品的重要属性之一。开展储藏加工过程营养品质的快速无损监测与评价具有重要意义。多光谱成像(Multispectral imaging,MSI)技术是一种近几年发展起来的食品快速无损检测新技术,它将光谱信息和成像数据结合起来,利用化学计量学技术对数据进行筛选建模,进而构建食品品质快速无损高效准确评价方法。本文对近五年国内外多光谱成像技术在肉类、果蔬和粮油作物营养品质检测方面的研究进展进行了总结和讨论,主要涉及到食品中水分、蛋白质、脂肪、可溶性固形物、生物活性物质等多种含量及变化。同时对多光谱成像技术目前的局限性进行了讨论,并对该技术未来的发展方向进行了展望,以期研发出可以应对复杂工业生产环境的在线多光谱成像检测设备。

Nutritional quality is one of the important attributes of food. Multispectral imaging( MSI) can be employed to noninvasively and rapidly evaluate food quality,which plays an important role in food nutritional quality. MSI simultaneously provides spectral and spatial information,models on the basis of chemometrics,and then builds a non-destructive rapid detection system of food quality.This review discusses and summarizes the researches of MSI applied to the nutritional quality of meat,garden stuff,and oil and grain crops,which includes content and change of moisture,protein,fat,soluble solids and bioactive component in food.At the same time,the current limitations of multi-spectral imaging technology are discussed,and the future development direction of the technology is prospected,so that online multi-spectral imaging detection equipment can be researched and developed,and it can cope with complex industrial production environment.
