Yunnan Provincial Standard of the People's Republic of China
Latest
DB53/T 498-2013
Scope
This standard specifies the near-infrared diffuse reflectance spectroscopy method to determine the main chemical composition indicators in tobacco and tobacco products, including: total volatile bases, water-soluble sugars (water-soluble total sugars, reducing sugars), total plant bases, total nitrogen, chlorine, total Requirements for protein, potassium, calcium, magnesium, petroleum ether extract, chlorogenic acid, rutin, starch, pH value and ash content. This standard is applicable to the analysis of main chemical composition indicators in tobacco and tobacco products (solid powder with particle size ≤0.4 mm) in the near-infrared spectrum region (12 800 cm-1 ~ 4 000 cm-1 or 780 nm ~ 2 500 nm) Determination. This standard does not apply to arbitration inspections.
