Investigation of the Effects of Different Home Frying Methods (Air Fryer and Deep Fryer) on HMF and Aroma Compounds in Gluten‐Free Bean Chips

open access: yesFood Science &Nutrition, Volume 13, Issue 10, October 2025.
In this study, functional gluten‐free chips were produced using red and black bean flours and different frying methods (deep fat and hot air frying), and HMF and flavor components were analyzed. Chips fried with hot air had lower fat content but were harder, lighter in color, and had higher HMF levels.

Effects of Different Particle Sizes of Ultrafine Indica Rice Flour and Lactobacillus casei on the Fermentation and Flavor Characteristics of Danling Dongba

open access: yesFood Science &Nutrition, Volume 13, Issue 10, October 2025.
This study found that ultrafine indica rice flour (12.22 μm) exhibited superior hydration properties (WAI 2.32 g/g, WSI 2.05%, SP 9.26 g/g) and higher pasting viscosity (peak viscosity 7632.53 cP). Lactobacillus fermentation increased volatile flavor compounds from 42 to 72, with L. plantarum 550 enhancing fruity esters and L.
