Sturdy on Non-Destructive Measurement System using Hyperspectral Imaging for Strawberry and other fruits and vegetables.

近年来，消费者对农产品的质量和安全性提出了更高的要求。对食品质量进行严格检测的无损检测技术变得越来越重要。因此，在采后加工过程中，需要更准确的质量测量技术来分拣草莓等水果和蔬菜。本研究的主要目的是利用目前美国比较热门的高光谱成像技术，开发一套用于水果品质检测的综合系统。利用高光谱成像技术对草莓、芒果、桃子和茄子进行了内外食品质量检测(成熟度、虫害、硬度、瘀痕、可溶性固形物含量、色素功能等)。研究成果概述如下：1.草莓、桃和芒果的品质(1)草莓和桃子在近红外波段(600-1000 nm)的特殊光谱图像分别为825 nm和980 nm，桃子为810 nm。但…紫肉甘薯和茄子色素的功能(花色苷色素的估算)紫肉甘薯和茄子花色苷色素的最强吸收光谱波长分别为525 nm和716 nm。光谱图像吸光度与花色苷测定值的相关系数在0.75~0.97.3之间。高光谱图像质量检测综合系统的研制。它是一种简化的非破坏性类型，成本低。较少

Recently, consumers are demanding for higher quality and better safety of agricultural produce. A non-destructive measurement technique for inspecting food quality strictly is becoming more important. Thus, more accurate quality measurement techniques are needed for sorting fruits and vegetables such strawberry during post-harvest processing. The main goal of this research is to develop a synthesis system of quality measurement for inspecting fruits using a hyperspectral imaging which is hotter technique at USA. Measurement using hyperspectral imaging was carried out an external and internal food quality inspection (ripeness, insect damage, firmness, bruises, soluble solids content, function of pigment etc. for strawberry, mango, peach and eggplant. An outline of research results was as follows.1. Quality of strawberry, peach and mango(1)The special spectral image at NIR (600-1000nm wavelength)for detecting was 825nm and 980nm wavelength on strawberry,810nm wavelength on peach. But the … More re was not special spectral image on mango.(2)The special spectral image at MR (600-1000nm wavelength)for an estimation of a soluble solids content and a ripeness was that the three-wavelength prediction model for strawberry of 50% ripe over was correlation at 0.78 over, and the five-wavelength prediction model for mango and peach was correlation at 0.79, 0.80 respectively.Hyperspectral imaging was found very useful for the non-destructive estimation of external and internal quality of fruit and fruit-vegetables.2. Function of pigments of purple-fleshed sweet potato and eggplant (an estimation of anthocyanin pigments)The most strong absorbance spectral wavelength of anthocyanin pigments was 525nm on purple-fleshed sweet potato, and 716nm on eggplant. The relationship between absorbance of spectral image and measured anthocyanin pigment was a correlation coefficient at 0.75-0.97.3. Develop of a synthesis system of quality measurementA synthesis system of quality measurement using a hyperspectral image was developed. It was a simplified non-destructive type and low cost. Less
