It is also the main means of resource utilization of tobacco waste. However, RT products are often limited in their wide application due to the traditional monotonic flavor from the poor stability of added flavor agents during processing. It is of considerable interest to investigate flavor diversification of RT. In this study, the effects of ultra-fine apricot powder with different particle sizes and addition rates on the characteristics of RT were investigated. The result shows to optimize the performance of physical and chemical indexes of RT, an 800 mesh is the most appropriate particle size and the powder addition rate should be below 15 %. The uniformity of dry weight improved 26.0 %, color difference (L*, a*, b*) 29.1 %, 23.5, 33.8 % respectively. The color difference (ΔE) between it and the standard sample of natural tobacco leaves optimized by 38.7 %. 14 % apricot powder added in forming pulp and 0.15 % apricot extracts added in coating liquid is the best combination in obtaining RT finished products with apricot characteristic aroma and natural fruity taste.

Because of this, there is a clear demand in the winemaking community for analytical tools that allow real-time, fast and inexpensive quantification of lactic acid. An approach using Raman spectroscopy has positioned itself as a feasible alternative in this regard. The primary goal of this work is therefore to monitor the concentration of lactic acid (which changes rapidly during the malolactic fermentation process) in the analysed samples, specifically, Nebbiolo wine samples for making the Barolo wine.

This review systematically summarizes recent advances in PEC sensing of TCs. We begin by categorizing the photoactive materials employed in PEC sensing and examining their structural design strategies, heterojunction engineering, and photoelectric properties. Subsequently, we elaborate on the fundamental signal transduction mechanisms, including the intrinsic redox activity of TCs, steric hindrance-induced current suppression, and coordination-mediated modulation of interfacial charge transfer. Furthermore, we highlight representative PEC sensing systems reported for TCs detection, classifying them based on recognition strategies such as aptamer binding, molecular imprinting, electrostatic adsorption, and site-specific coordination—each linked to distinct signal generation modes. Finally, current limitations and promising strategies for further performance enhancement of PEC sensors are discussed.
