Non-destructive detection of two cucumber cultivars fruit quality using NIR Spectroscopy

Abstract

Cucumber fruit quality can be detected by the non-destructive method such as NIR Spectroscopy. NIR determines the content quality of the product rapidly, precise, and accurate. This study aims to predict the quality component of cucumber cultivars Bandana and Wulan by a non-destructive method using portable NIR. The experiment was conducted at Post Harvest Laboratory of Agriculture Faculty of Padjadjaran University and the instrument used to measure the fruit quality in a non-destructive way was the NIR (NirVana AG410, Integrated Spectronics Pty, Ltd, Australia). To determine cucumber internal quality it was done from the evaluations obtained by a non-destructive method (NIR) and a destructive method. The calibration and validation models are built using the partial least squares (PLS) method. The result shows that the quality component of the non-destructive cucumber method using NIR has accuracy values similar to the conventional method. In the observed result quality component, the correlation coefficient (R) was close to 1.00 and the standard error of calibration (SEC) was low or close to 0.00.
