“…Developing a noninvasive portable detector to determine sugar content of kiwifruit would be welcome by kiwifruit planters, distributors, sellers, and consumers. Owing to the characteristics of sensitivity to the C‐H, N‐H, and O‐H absorptions related to food components, simple sample preparation, nondestructive measurement, and fast response time, visible/near‐infrared (Vis/NIR) spectroscopy has been widely applied in determining sugar content of various fruits, such as apple (Giovanelli, Sinelli, Beghi, Guidetti, & Casiraghi, ; Zou, Zhao, Huang, & Li, ), pear (Fan, Huang, Li, Zhao, & Zhang, ), strawberry (Amodio, Ceglie, Chaudhry, Piazzolla, & Colelli, ), peach (Nascimento, Carvalho, Júnior, Pereira, & Teixeira, ), Goji berry (Li, Yu, & Gao, ), and orange and grapefruit (Ncama, Opara, Tesfay, Fawole, & Magwaza, ). Some reports have also been found on detecting sugar content of kiwifruit (Cai, Tang, Lü, Zhao, & Chen, ; Chen & Han, ; Guo & Liu, ; Li, Pullanagari, Pranamornkith, Yule, & East, ).…”
