Objective: This study aimed to improve the tenderness and flavor content of Yanbian cattle beef. Methods: Rump beef of Yanbian cattle were dry-aged by using three different methods, i.e., Method A: RH（65±5）% aging for 10 days, RH（75±5）% aging for 10 days, and then RH （85±5）% aging for 20 days; Method B: RH（75±5）% aging for 20 days and then RH（85±5）% aging for 20 days; Method C: RH（85±5）% aging for 40 days. The quality changes caused by the different aging processes were then analyzed and compared. Results: The cooking loss of the beef processed by all the three methods increased significantly with …

In the process of vegetable fermentation, the variety and quantity of microorganisms are complex and changeable. Lactic acid bacteria (LAB), as the main power in the process of vegetable fermentation, participate in the regulation of various metabolic pathways and affect the formation of flavor. In this review, the changes of major flavor metabolites during vegetable fermentation and their internal relationship with the community structure and abundance of LAB were summarized, then the potential mechanism of LAB fermentation to produce flavor substances was discussed. Moreover, the application of LAB in vegetable fermentation was prospected.

Objective: To determine the key points of pear quality formation and deterioration of different Pyrus pyrifolia pears during cold storage. Methods: Zaoshengxinshui, Hujingli18, Hujingli67 were used as materials, the fruit of three varieties with the same ripeness were stored in cold storage at （1.0±0.5） ℃ and relative humidity of 85%~90% for 60 days, fruit texture, total soluble solids, titratable acid, sugar and acid contents and 10 sensor values were determined every 10 days. Results: Hujingli18 and Zaoshengxinshui were the typical type of fructose accumulation,Hujingli 67 was the type of sorbitol accumulation, and all three varieties were the type of malic …

In this study, highland barley wine was produced with roasted barley to increase the flavor of the wine. Physical-chemical properties such as pH value, total acid, total sugar, alcohol content of the wine and flavor were determined. The evaluations of acidity, sugar content and sensory of the wine were found increased with roasted barley, and roasting improved the variety of flavor substances for the highland barley wine. Nonanal, phenylethyl alcohol, benzeneacetaldehyde and decanal were determined to be the key flavor substances of the four barley wines (ROAV＞1). Acetophenone and geranylacetone were found to be the modified compounds to barley wines …

The volatile components of okra flower tea and its soup prepared using different drying methods were tested and analyzed by high throughput time of flight mass spectrometry (GC-TOF-MS), and the components of okra flower tea and its soup were determined. The results showed that 194 volatile compounds were identified in okra flower tea and its soup prepared by using the two drying methods. Among them, organic acids, sugars and amino acids were the main ones. The relative contents of sugars, organic acids, alcohols, amides, esters, sulfonic acids and glycosides in freeze-dried flower tea and its soup were higher than those …
