The meter analyzes sugar content, color and dry matter. Findings on its uses with mangoes, tomatoes and cherries were discussed during an Aug. 18-20 congress symposium on nondestructive assessment of fruit attributes.
“It is a handheld instrument that can be used at any point of pre- and post-harvest to identify ideal ripeness by measuring ripeness indices customized for that fruit,” Michael Larman, general manager of Camas, Wash.-based Felix Instruments, said in a news release.
The need for cost effectiveness in harvesting decisions and the challenges of long-term shipping and storage have helped create the demand for commercial sensor solutions, according to the company.
The spectrometer was a scheduled topic in four workshops at the Aug. 17-22 congress.
It was mentioned in:
- “Applying Nondestructive Sensors to Improve Fresh Fruit Consumer Satisfaction,” by Carlos Crisosto, University of California, Davis;
- “Using Data from In-situ Fruit Assessment to Inform Pre- and Post-harvest,” by Manuela Zude, vice president of the German Society for Horticultural Science;
- “Comparison Between an Acoustic Firmness Sensor and Near Infrared Spectrometer,” by Andrew McGlone, senior scientist at New Zealand Institute for Plant and Food Research; and
- “In-Field Monitoring of Tomato and Mango Fruit Dry Matter and Colour,” by Kerry Walsh, Central Queensland University.
Felix Instruments is a subsidiary of CID Bio-Science, Inc.
“It offers handheld data collection that can be carried from tree to tree, orchard to orchard, and then brought inside to the packinghouse, storage rooms, delivery trucks (and) right into the grocery store,” Larman said.
