This research aimed to explore binding interactions between pea protein isolate (PPI) and selected strawberry flavorings including vanillin, γ-decalactone, furaneol, and -3-hexen-1-ol within an aqueous system. The results showed that binding affinities of PPI with all various functional group of flavor compounds decreased as temperature increased from 5 °C to 25 °C. Notably, at 25 °C, γ-decalactone displayed the highest binding affinity, followed by vanillin, -3-hexen-1-ol, and furaneol.

However, there is an increase in interest in minimally processed chocolate products due to their potential positive health benefits. The odor-important compounds and sensory characteristics of minimally processed (unroasted) and conventionally roasted dark chocolates were determined by gas chromatography-olfactometry, aroma extract dilution analysis (AEDA), and stable isotope dilution analysis (SIDA).

However, heat treatments can degrade protein quality by damaging essential amino acids, as well as contribute to the Maillard reaction. The Maillard reaction forms melanoidins that favorably improve food qualities (e.

The target compound was extracted from oak wood and various oak-aged spirits and analyzed by multidimensional (heart-cut) gas chromatography-mass spectrometry-olfactometry (MD-GC-MS-O), and was unambiguously identified as the sesquiterpene ketone, 5-isopropenyl-3,8-dimethyl-3,4,5,6,7,8-hexadydro-1()-azulenone (rotundone). Quantitation of the trace-level target compound was done by stable isotope dilution analysis (SIDA) in a variety of oak-aged spirits, including bourbon, rye, Tennessee whiskey, scotch, rum, and tequila.

Sun drying and heat pump drying resulted in comparable levels of CGAs and antioxidant activities in green coffees; however, color parameters, especially lightness (L*), differed. Correlation analyses indicated a relationship between specific CGAs, antioxidant activities and color parameters among coffees.
