Assessing the impact of limited and extended oven heating exposure on the stable hydrogen and oxygen isotopic composition of wheat-processed products with varying formulations.

This study aims to assess the effects of oven heating on the isotopic ratios of eight formulated wheat-processed products with different gluten-to-starch ratios. Two heating treatments were applied: limited heating in an oven with exposure to 100 °C for a specific time (cooking time-dependent) and extended heating in an oven with exposure to 100 °C, 180 °C and 260 °C for 6 min. Results showed limited heating exposure did not alter the δH and δO in the wheat-processed products.
