Exploring portable NIR spectroscopy in transmittance and reflectance modes for the authentication of Brazilian coffees with geographical indications

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 7, Page 4038-4048, May 2026.
Abstract BACKGROUND Geographical indications (GIs) certify the link between coffee origin and quality, enabling premium pricing and protecting producers. However, the high market value of GI coffees increases their vulnerability to fraud, underscoring the need for reliable and practical authentication methods.

Physicochemical and Thermal Evaluation of a Mixed‐Mode Greenhouse Solar Dryer for Guava (Psidium guajava L.)

open access: yesJournal of Food Science, Volume 91, Issue 5, May 2026.
ABSTRACT The present study aimed to evaluate the quality and nutritional properties of guava slices dried in a greenhouse solar dryer (operated under mixed and direct modes) and an electric stove at 50°C. The results showed that mixed‐mode solar drying resulted in greater retention of vitamin C (112.60 mg/100 g), carotenoids (0.37 mg/g), and ...
