NIR spectroscopy for peaches and nectarines

United States

Thursday 15 July 2021

For peaches and nectarines, NIR spectroscopy can be used on different stages of fruit production. It is applicable to determine maturity to set harvest time by evaluating Index of Absorbance Difference (IAD) and firmness; estimate BRIX to measure Soluble Solids Concentration (SSC) for selection of fruits for fruit processing (jams, juices, etc.).

Quality parameters are useful in different stages of a supply chain and can be used to estimate maturity, monitor quality and select fruits for processing.

Near Infra-red (NIR) spectroscopy can be applied for the non-destructive, quick, and cost-effective chemical analysis of the internal qualities.

They can also identify possible wooliness in fruit stored for a month and longer. “Wooly” fruits cannot be used for consumption like fresh fruits, but could be processed for various uses.

The F-750 Produce Quality Meter

by Felix Applied Food Science Instruments is a NIR spectrometer that can measure titrable acids, SSC, and internal and external color within a few seconds. It is small, portable and can be used with one hand. An easy model building software allows it to customize it for peaches, nectarines or any other fruit.

Due to its portability, farmers, suppliers, fruit processors, and retailers can use it on the field, factories, warehouses, shops or factories. Users can take as many readings as needed by NIR tools, as it works non-destructively and gives results immediately for quick decision making.

Since they can be used multiple times and on numerous fruits in a short time, the instruments bring the cost of quality analysis down and make it affordable for all people.
