In order to decrease the content of reducing sugar in reconstituted tobacco (RT), Maillard reaction was brought about by adding amino acids in tobacco extract and FeCl3 as catalyst, going through extract concentration under reduced pressure, applying and drying steps analogous to real RT production. The content of reducing sugar was determined with HPLC, and the effects of different amino acids, addition rates of amino acids and catalyst, pH of extract, and conditions of extract concentrating, applying and drying on the reducing sugar content were investigated. The results showed that: 1) When reducing sugar/amino acid ratio in extract was 1 ∶0.5 (mole ratio), Fe3+ concentration 0.01 mmol/L, pH adjusted to about 6.2 by 2.5 mol/L K2CO3, the content of reducing sugar in RT could be decreased subject to simulated concentrating, applying and drying. Comparing with the control, the reducing sugar content in RT treated with lysine, glycine and proline decreased by 10.6%, 9.1% and 6.0%, respectively. 2) Comparing with the control, the irritancy of the RT treated with amino acids decreased to a certain extent, the aftertaste was improved; and the glycine-treated RT offered the best smoking quality. ©, 2014, Editorial Office of Tobacco Science and Technology.

Zeta potential and anionic trash of stock flow system and wet end of manufacturing reconstituted tobacco by paper-making process were determined by Zeta potential and particle charge detectors. During a production cycle, the average Zeta potential and cationic demand in head box were -7.06 mV and 970 μmol/L respectively. The results showed that cationic trash mainly came from thick white water. Source

In order to investigate the variation of polyphenols in the production of paper-making process reconstituted tobacco, three polyphenols, including chlorogenic acid, scopoletin and rutin, were analyzed by high performance liquid chromatography. And the effects of extraction temperature, ethanol concentration and concentration temperature on polyphenol contents were studied. The results showed that: 1) The contents of the three polyphenols in tobacco dust and scrap were higher than in tobacco stem, however, the percentage of scopoletin in polyphenols was higher in tobacco stem. 2) The base-sheet of reconstituted tobacco contained small amount of polyphenols, while a larger proportion of the polyphenols was washed out by white water. The effective utilization rates of chlorogenic acid, scopoletin, and rutin were 70.8%, 47.1%, and 72.4%, respectively. 3) Within the range from 40 to 90°C, higher temperature was beneficial to the extraction of polyphenols. The extraction efficiency of the polyphenols was the highest when the concentration of ethanol in the extractant was 70%. With the rise of concentration temperature, the contents of the polyphenols in extract reduced gradually. This study provided a reference for the regulation and control of polyphenols in the production of paper-making process reconstituted tobacco. Source

The protein in tobacco imparts negative effect to the taste of tobacco and tobacco products. In order to improve the sensory quality of paper-making process reconstituted tobacco, bentonite was used to remove protein from tobacco extract during processing, and the effects of bentonite addition rate, tobacco extract pH, treatment temperature and time on the removal of protein were investigated. The sensory quality of resultant reconstituted tobacco samples was evaluated as well. The results showed that: 1) The removal of protein from tobacco extract was significantly influenced by bentonite addition rate, tobacco extract pH and temperature, while it was slightly affected by treatment time. 2) The optimal treatment conditions were bentonite addition rate 8 g/L, pH 4.91, temperature 60℃ for 10 min, under which, the protein content in the extract reduced from 4.55% to 1.36% (decreased by 70.1%). 3) After treating with bentonite, the offensive odor and aftertaste of paper-making process reconstituted tobacco improved to a certain extent. © 2015, Editorial Office of Tobacco Science & Technology.
