In situ ripening stages monitoring of Lamuyo pepper using a new-generation near-infrared spectroscopy sensor.

The viability of NIRS for measuring dry matter content and soluble solid contents in situ, using a new-generation NIRS sensor, was demonstrated. However, the high water content, the irregular shape of the fruit, and the fact that it is hollow inside all point to the need for using larger samples sets so as to increase the robustness of the models obtained. © 2019 Society of Chemical Industry.
