Article Abstract
Ghee (milkfat from heat clarification) was made using direct cream (DC), cream butter (CB) or pre-stratification (PS) methods and stored at 60°C, in air, for at least two weeks. Milkfat degradation, particularly oxidation, occurred in all types of ghee, resulting in increases in aldehydes and free fatty acids. However, there was little difference in fat degradation rates in each type of ghee. DC and CB ghee contained volatile Maillard reaction products, whereas PS ghee did not. The concentrations of 3,4-dihydroxy-3-hexen-2,5-dione (DHHD) and 2,3-dihydro-3,5-dihydroxy-6-methyl-4(H)-pyran-4-one (pyranone), Maillard reaction products found in DC and CB ghee, rapidly decreased during storage, associated with increases in acetic acid. This work suggests hydration of both DHHD and pyranone, during storage, could form reactive 1-deoxy-d-erythro-hexo-2,3-diulose (1-deoxyglucosone) that degrades mostly to acetic acid. Thus, the Maillard reaction cascade appears to continue in food, in the absence of proteins and sugars, long after cooking has ceased.

As the primary storage protein, highland barley gliadin (HBG) exhibits limitations in the processing of highland barley foods, primarily due to its abundant non-polar amino acids. In this study, HBG was utilized to prepare sugar-HBG complexes with pentose (xylose), hexoses (glucose and galactose), and disaccharides (lactose and maltose) in an aqueous system at a pH of 11 and a temperature of 75 °C. Subsequently, the structural and functional characteristics of these complexes were evaluated.

This study investigated the formation of characteristic aroma compounds in braised pork during electromagnetic cooking, focusing on the effect of added seasonings on lipid oxidation and the Maillard reaction. The accelerated lipid oxidation led to a rapid increase in the levels of most characteristic aldehydes, 1-octen-3-ol, and 2-pentylfuran during the temperature-rising stage (S0-S2) and the simmering stage (S3-S4) in braised pork. However, the addition of seasonings inhibited polyunsaturated fatty acid oxidation, reducing the levels of these lipid-derived aroma compounds during the sauce thickening stage (S5).

This study presents a biopreservation method using sourdough co-fermented with Fructilactobacillus sanfranciscensis and Propionibacterium freudenreichii, optimizing conditions to 220 hydration and 24 h fermentation. The composite sourdough bread quality was evaluated through physicochemical, storage, sensory, and microbial tests, with mechanisms analyzed based on microstructure, rheology, and dough structure. Results showed that: first, the composite sourdough enhanced bread physicochemical properties, increasing volume, height-to-diameter ratio, elasticity, and resilience, while reducing baking loss, hardness, chewiness, and adhesiveness.

This study employed high-pressure microfluidization (HPM) to facilitate the Maillard reaction between quinoa protein (QP) and dextran (DX), systematically examining the effects of various pressures on the conjugate's physicochemical properties. Fourier transform infrared spectroscopy confirmed the formation of QP-DX conjugates, characterized by a new peak at 1149 cm (covalent CN bond). Secondary and tertiary structure analyses revealed that HPM-assisted Maillard reaction partially unfolded QP molecules, enhancing conformational flexibility and interfacial properties.
