以近紅外光技術量測葡萄之花青素含量

在全球老化的時代，人口結構轉變，高齡族群比例升高，同時經濟結構轉型也加速了農業就業人口平均年齡老化的問題。現今社會中，歐洲、日本與台灣皆面臨了農業就業人口減少，且近數十年來就業人口快速老化的問題。這種現象導致農業就業人士青黃不接，長者的經驗難以傳承給年輕世代的年輕人。除此之外，經濟狀況改善的現在，消費者傾向購買有品質檢測認證且營養含量更高的產品。葡萄國際上一項重要的經濟作物與葡萄酒的原料，葡萄中的花青素是一種水溶性並且有抗氧化、抗發炎與抗癌潛力的成分，其含量可以影響到葡萄與葡萄酒的色澤，同時也是葡萄與葡萄酒品質認證的一項重點。近紅外線光譜儀可以在不破壞食物的前提下快速檢測出食物中的成分。在本研究中，我們聚焦在用近紅外線光譜儀量測葡萄中的花青素含量，希望未來能建構並改善一個非親破壞性的量測與品管標準。加上花青素的醫學價值，我們期望能夠將此與商業策劃結合開發出新的商業模式，且協助缺乏經驗的年農夫能夠使用近紅外線光譜儀來協助他們採收品質優良的葡萄。

As people worldwide live longer, aging world population becomes a serious problem. The change of industries caused by economic changes speed up the aging of farmers. Nowadays, fewer and fewer individuals in Europe, Japan and Taiwan choose farming as an occupation than before and the averaged age of farmers grows rapidly in recent decades. The phenomena make the experience of elder farmers hard to pass down to the young generation. Besides, consumers nowadays seek for products with higher nutrition contents and better quality. Grapes are important economic crops and the raw material is utilized to produce wine all over the world. The color of grapes and wine is determined by the amount of anthocyanins, the water-soluble pigments which have antioxidant, anti-inflammatory, and anticancer properties. Near-infrared (NIR) spectroscopy was used to detect foods’ ingredients in a short time with a non-destructive manner. In this study, we focus on detecting the content of anthocyanin by NIR spectroscopy and hope a new quality control standard can be built based on the improved non-destructive procedure. Combining the research of the medical value of the anthocyanin, a new marking strategy may be developed. In addition, the technology has the potential to assist young farmers who lack of the experience can use the NIR spectroscopy to harvest grapes with good quality.
