Embodiment 1

[0029] Using glucose, xylose and phenylalanine as raw materials, prepare 1000 mL of glucose-phenylalanine solution and xylose with reducing sugar concentration of 0.05mol / L according to the ratio of reducing sugar and amino acid molar ratio of 1:1 - phenylalanine solution with K 2 HPO 4 or KH 2 PO 4 Buffer to adjust its pH to 5.5. Take 100 g of qualitative filter paper and soak them evenly in 1000 mL of glucose-phenylalanine solution and xylose-phenylalanine solution for 2 h, then take out the filter paper and spread it out to dry, and place it at a temperature of (22±1) o C and relative humidity (60±2)% in a constant temperature and humidity environment for 48 hours, and then shredded with a tobacco leaf cutter to obtain two kinds of simulated shredded tobacco. Use a throat sprayer to adjust the moisture content of the simulated cut tobacco to about 20%. Then put each group of 2 g cut tobacco at 70 o C. 100 o C and 130 o C Dries silk for 3 min, 6 min, 9 min, 12 min an...

Embodiment 2

[0031] Prepare 1000 mL of a solution with a fructose concentration of 0.1 mol / L according to the molar ratio of fructose and proline at a ratio of 1:1, and use Na 2 HPO 4 or NaH 2 PO 4 Adjust the pH of the buffer solution to 7.4 to obtain a fructose-proline solution. Take 100 g of qualitative filter paper and soak it in 1000 mL of fructose-proline solution evenly for 1 h, then take out the filter paper and spread it out to dry, and place it at a temperature (22 ± 1) o C and relative humidity (60±2)% in a constant temperature and humidity environment for 48 hours, and then shred it with a tobacco leaf cutter to obtain simulated shredded tobacco. Use a throat sprayer to adjust the moisture content of the simulated cut tobacco to about 20%. Then each group of 2 g simulated tobacco at 80 o C. 110 o C and 140 o C Dries silk for 3 min, 6 min, 9 min, 12 min and 15 min respectively. The shredded tobacco after drying was shaken and extracted with 50 mL of distilled water for 1 ...

Embodiment 3

[0037] According to the ratio of xylose and proline molar ratio of 3:1 or 1:3, prepare 1000 mL solution with xylose concentration of 0.1 mol / L and 1000 mL solution with proline concentration of 0.1 mol / L, and use K 2 HPO 4 and KH 2 PO 4 The pH of the buffer was adjusted to 9.0 to obtain two xylose-proline solutions. Take 100 g of qualitative filter paper and soak them evenly in these two xylose-proline solutions for 1 h, then take out the filter paper and spread it out to dry, and place it at a temperature of (22±1) o C and relative humidity (60±2)% in a constant temperature and humidity environment for 48 hours, and then shred it with a tobacco leaf cutter to obtain simulated shredded tobacco. Use a throat sprayer to adjust the moisture content of the simulated cut tobacco to about 20%. Take 10 g simulated shredded tobacco at 120 o C and dry silk for 10 min. After drying, place it in a conical flask, add 50 ml CH 2 Cl 2 , and then add 10 μL of phenethyl acetate (CH 2...

Abstract

The invention discloses a preparation method of simulated tobacco shreds and a method for analyzing and researching the maillard reaction in a cigarette tobacco shred drying procedure by using the simulated tobacco shreds. The preparation method is characterized in that the simulated tobacco shreds which do not contain maillard reaction products are prepared from filter paper, reducing sugar and amino acid which serve as raw materials, and the tobacco shreds are used for researching the maillard reaction in the cigarette tobacco shred drying procedure. The preparation method has the advantages that (1) the filter paper with the character similar to that of tobaccos is used as a matrix, and the reducing sugar and the amino acid are added to prepare the simulated tobacco shreds which do not contain intermediate products and final products of the maillard reaction and can avoid interference caused by the maillard reactionproducts contained in tobaccos and enable the research on the maillard reaction in the tobacco shred drying procedure to be more accurate and targeted; (2) by setting of the types and ratios of the reducing sugar and the amino acid, a system pH, a heating condition and the like, a model system with different reaction conditions is obtained, and the influence of various reaction factors on the maillard reaction in the tobacco shred drying procedure can be inspected respectively.

Description

technical field [0001] The invention belongs to the technical field of tobacco, and in particular relates to a method for preparing simulated shredded tobacco and a method for using simulated shredded tobacco to analyze and study the Maillard reaction in the shredded cigarette drying process. Background technique [0002] The shred drying process is an important link in the cigarette shred making process. Under the temperature conditions of the shred drying process, Maillard reaction can occur to generate small molecular compounds and melanoidin-like substances, which have an important impact on the aroma and color of tobacco. Therefore, the study of Maillard reaction in the drying process has important guiding significance for the control of sensory quality in the cigarette production process. [0003] At present, the research on Maillard reaction in the cigarette manufacturing process is carried out directly using tobacco as a sample (References 1, 2). The processes that ...
