Hops provide the characteristic bitter taste and attractive aroma to beer; in this study, hops were replaced by jasmine tea extract (JTE) during late-hopping. The addition of JTE improved the beer foam stability 1.52-fold, and increased the polyphenol and organic acid contents. Linalool was the most important aroma compound in hopped (HOPB) and jasmine tea beer (JTB), but other flavor components were markedly different, including dimeric catechins, flavone/flavonol glycosides, and bitter acids and derivatives. Sensory evaluation indicated that addition of JTE increased the floral and fresh-scent aromas, reduced bitterness and improved the organoleptic quality of the beer. The antioxidant capacity of JTB was much higher than that of HOPB. The inhibition of amylase activity by JTB was 30.5% higher than that of HOPB. Functional properties to beer were added by substituting jasmine tea extract for hops during late hopping.

Jasmine tea, a further processing tea made by scenting green, black, oolong, or other tea with jasmine flowers, is widely appreciated worldwide for its fragrant aroma, refreshing taste, and beneficial health effects. The production of jasmine tea is a meticulous and complex process that involves chemical reactions, physical adsorption, and flavor interaction effects at the sensory level between jasmine and tea. This paper provides a comprehensive review of the research on the processing technology, characteristic aroma formation, nonvolatile compounds, and health benefits of jasmine tea.

Air pollution is a critical threat to human health and the quality of life in large cities. In this work, we electrically characterized indoor air quality in Dhaka City with a microcontroller-based advanced sensing system in the presence of 60 air purifiers. We conducted LabVIEW-controlled, fully automated, and remotely operated experiments to precisely monitor, store, and analyze the air-purifying effects in the concentrations of air quality index (AQI) parametersPM2.

In this study, the aroma characteristics of jasmine tea (JT) scented by three kinds of multipetal jasmine, Xiangfei 2, 4 and 11 were investigated with common double-petal jasmine as control. Compared with the strong floral aroma of double-petal jasmine tea (TS), the JT scented with Xiangfei 2 (TC) showed fresher aroma, the JT scented with Xiangfei 11 (TB) exhibited sweeter aroma, while the overall aroma of JT scented by Xiangfei 4 (TA) was overall lower. Among them, Benzoic acid, 2-hydroxyl-, ethyl ester contributed to TB's sweet note, 3-Hexen-1-ol, benzoate, (Z) - and Methyl salicylate were related to the fresh aroma of TC, Linalool, Methyl anthranilate, 4-Hexen-1-ol, acetate and Benzyl alcohol were linked to TS's floral aroma.

Jasmine tea (JT) is a scented tea that utilizes the adsorption properties of processed tea to adsorb the aroma released by jasmine flowers. JT boasts a long history of production and consumption, stands out in the competitive tea market for its distinctive blend of tea and jasmine aromas, and has gained increasing prominence among consumers and researchers worldwide. In recent decades, more research has been conducted on JT, including the chemical basis for the formation of the characteristic flavor, the improvement of the process, and the potential health benefits.
