  • Patent number: 10542771
    Abstract: This invention relates to a method for preparing expanded tobacco stems, characterized in that the method contains steps as follows: purification, stem expansion, hypoxia heat retention (hypoxia heat retention refers to heating the expanded stems at hypoxia environment and maintaining the temperature), natural stacking, sorting, and packaging. An expanded tobacco stem product prepared according to this method has uniform size and color. Taste is modest and plain when it is combusted, which does not affect the original taste flavour. Expansion volume, the ratio of the expanded stems to the total stems, and quality are stable, which can be used as adsorption material. More important, expanded tobacco stems made from stems of different origin, texture and year according to this method have uniform odor component, which can not be acquired by other expansion technologies. This technology has met the requirement for product fabrication.

  • Publication number: 20140190499
    Abstract: In one aspect, there is provided a method for reducing the formation of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone and N-nitrosonornicotine and N-nitrosoanatabine and N-nitrosoanabasine in a tobacco homogenate comprising the steps of: (a) providing a tobacco homogenate; (b) increasing the pH of the tobacco homogenate to at least about pH 6.0; (c) optionally measuring the concentration of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone and N-nitrosonornicotine and N-nitrosoanatabine and N-nitrosoanabasine in the tobacco homogenate before and after the pH treatment in step (b); and (d) obtaining a tobacco homogenate in which the levels of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone and N-nitrosonornicotine and N-nitrosoanatabine and N-nitrosoanabasine are reduced as compared to the levels of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone and N-nitrosonornicotine and N-nitrosoanatabine and N-nitrosoanabasine in the tobacco homogenate provided in step (a).

  • Publication number: 20140137877
    Abstract: Provided is a method for blending of agricultural product utilizing hyperspectral imaging. At least one region along a sample of agricultural product is scanned using at least one light source of different wavelengths. Hyperspectral images are generated from the at least one region. A spectral fingerprint for the sample of agricultural product is formed from the hyperspectral images. A plurality of samples of agricultural product is blended based on the spectral fingerprints of the samples according to parameters determined by executing a blending algorithm.
