Embodiment 1
[0080] Embodiment 1, a kind of preparation method of tobacco moist leaf double-low material liquid, carries out following steps successively:
[0081] 1) Preparation of tobacco polyphenol parts:
[0082] Take 1 kg of tobacco that has been crushed into 1-2 cm lumps, add 8 kg of water, start heating in a 20-liter extractor with a reflux heating device, and count when there is reflux liquid in the condenser, heat extraction for 1.5 hours Afterwards, stop heating, interlayer enters cooling water, when making extraction pot drop to room temperature, discharge extracting solution from feeding port, re-add 6 kilograms of clear waters in the pot, repeat extraction once with the above operation conditions, emit second time extracting solution; Merge two The secondary extract was separated by a solid-liquid centrifuge to obtain 14.5 kg of clarified liquid (that is, tobacco water extract).

Embodiment 2
[0099] Embodiment 2, the formula one among the embodiment 1 is changed into following formula two, all the other contents are the same as embodiment 1.
[0100] Recipe 2:
[0101] Maillard reaction products of tobacco polyphenols
Embodiment 3
[0102] Example 3. In the formula 1 in Example 1, the use of 5 parts of cinnamon bark tincture and 3 parts of Luo Han Guo extract (mogroside UV 5%) was cancelled, and the volume was also adjusted to 1000 parts with water; the rest of the contents were the same as in Example 1.
[0103] Experiment, the double-low feed liquid for moistening leaves of tobacco obtained in the above-mentioned embodiments 1 ~ embodiment 3 and the commonly used feed liquid (as shown in Table 1 in the background technology) are respectively carried out as follows:
