Embodiment 1
[0026] Stem washing: set up a transmission device in the stem washing tank, so that the tobacco stems and washing water flow relatively (the speed is controlled at 0.2m / s), the mass ratio of tobacco stems and washing water is 1:20, and the washing water contains quite 0.2% stem-washing complex enzyme (composed of 50% pectinase and 50% xylanase) in the mass of tobacco stems, and the water temperature was kept at 55°C during the stem-washing process. After washing the stems, the tobacco stems are further subjected to primary storage, moistening and secondary storage for a total of 4 hours.
[0027] Stem pressing and cutting: before pressing and cutting, the tobacco stems are heated and the tobacco stems are cooled respectively.
[0028] (3) Fragrance enhancement reaction of shredded stems:
[0029] Configure feed liquid and aromatizing compound enzyme:
[0030] Feed liquid: 1 part by weight of glucose, 1 part by weight of fructose, 0.05 part by weight of alanine, and 0.05 part...
Embodiment 2
[0035] Sample 0 (control group): as in Example 1, but the stem washing compound enzyme used is: 30% pectinase, 30% hemicellulase and 40% cellulase; the substance contained in the feed liquid is: 2 parts by weight Glucose, 2 parts by weight of alanine; the addition of flavoring compound enzyme is equivalent to 3% of the cut stem quality.
[0036] Sample 1: As in Example 1, but the aroma-enhancing compound enzyme used therein is trypsin: medium temperature α-amylase: cellulase: hemicellulase = 1:1:2:1. Cellulase is enzymatic activity FPA>18,000 u / ml (Trichoderma viride), hemicellulase is food grade, purchased from Ningxia Xiasheng Company); feed solution 1 is: 1 part by weight of glucose, 1 part by weight of fructose and 0.05 parts by weight of alanine and 0.05 parts by weight of proline.
[0037] Sample 2: Same as sample 1, but the feed liquid is composed of feed liquid 2, namely: 1 part by weight of glucose, 0.5 part by weight of fructose, 0.03 part by weight of alanine, and 0....
