Rice is one of the main staple foods of Chinese people and its quality requirements are also improving. Aroma is one of the evaluation factors of rice quality, rice with better aroma quality is often more accepted by consumers. A universal aroma descriptive lexicon was established and four flavor types were formed based on samples from 9 representative rice cultivation regions. The key variables affecting the sensory quality of Chinese rice flavor were screened. It was found that the hexanal and nonanal with the highest content had no effect on the flavor properties, which suggests that volatile organic compounds (VOCs) content is not necessarily related to the influence of flavor properties. According to the aroma analysis of different rice flavor types, it can provide guidance for other flavor research.

Seventy-eight autochthonous strains of were isolated from rice wine starter samples across twenty-nine regions in China to evaluate their potential in traditional rice wine fermentation. Strains were assessed for enzyme activity, antioxidant properties, amino acid production, and volatile flavour compounds. Significant variation in enzyme activities was observed, with acidic protease activity ranging from 280 to 1023 U/g, amylase from 557 to 1681 U/g, and esterase from 370 to 2949 U/g.

The effects of storage on rice flavor among different rice varieties have not been well studied. To address this gap, we analyzed volatile organic components (VOCs) identified by gas chromatography-ion mobility spectrometry (GC-IMS) and related physicochemical properties of different storage-tolerant rice varieties during storage. The results showed that VOCs of four rice varieties significantly changed after 6 months of storage; OPLS-DA analysis classified the four rice varieties into two groups.

Protein bar hardening negatively impacts shelf life, quality, and consumer acceptance. Although oxidation is known to negatively affect the flavor and texture of foods, the specific roles of lipid and protein oxidation in bar hardening have not been thoroughly investigated. Furthermore, most research has concentrated on dairy proteins, with a notable lack of studies addressing the hardening of plant-based protein bars.

The formation of flavor in traditional Chinese rice wine requires a long aging process. To accelerate the maturation of rice wine, a 20 L scale multi-sweeping- frequency mode ultrasonic reactor was employed in this study to explore the promoting effects. Rice wines were subjected under 10 combined types of sonication treatments with 20/28/40 kHz in single/double/triple frequencies, and in fixed or sweeping modes, respectively.

Cinnamon essential oil has gained widespread attention in the food industry as a safe and effective preservative. However, its low water solubility and high volatility limit its application in food, making the use of natural emulsifiers for its emulsification an increasingly popular focus of research. This study focuses on the extraction of galactomannan-rich aqueous extracts from Gleditsia sinensis seeds using a low-energy, low-pollution microwave-assisted method.
