[0077] (1) Pretreatment of samples to be tested
[0078] Pre-processing the flue-cured tobacco leaves to be tested through the three steps of manual tearing, removing stems and shredding. The processed tobacco slices (silk) are immediately sealed, labeled, and stored uniformly without confusion. The equipment is carefully cleaned before and after the moisture regain and shredding of different tobacco samples to ensure that the tobacco samples are well clustered.
[0079] (2) Select a sample of flue-cured tobacco leaves to be tested to determine 8 chemical components: linoleic acid, total sugars, total nitrogen, chlorogenic acid, malonic acid, total polyphenols, tobacco nicotine, volatile acid, assisted by microwave Derivatization-determination of non-volatile organic acids (linoleic acid, malonic acid) by gas chromatography; determination of water-soluble sugars (total sugars) by YC / T159-2002 continuous flow method; determination by YC / T161-2002 continuous flow method Total nitro...
