Non-destructive quality measurement system for cane stalks using a portable NIR instrument* [Full subscriber]

Abstract Sugar content of cane at the farm is important information for farmers and millers in Japan because cane prices are determined by pol in cane. While NIR systems have been used to measure cane quality at the mill, portable measurement systems for cane to detect chemical properties in the field have not been developed, although there are some commercially available instruments for fruits. We investigated direct non-destructive measurements for sugar content using a portable near infrared spectrophotometer. A portable fruit tester comprising a NIR spectrophotometer was modified for use in the transmittance mode and employed to quantify brix and…
