Method for detecting puff-by-puff stability of blueberry-flavored heated cigarettes by using nuclear magnetic resonance hydrogen spectrum

Abstract

The invention relates to a method for detecting puff-by-puff stability of a blueberry-flavored heated cigarette by using a nuclear magnetic resonance hydrogen spectrum, which comprises the following steps of: smoking by using a rotary puff-by-puff smoking machine by taking the blueberry-flavored heated cigarette as an object, collecting aerosol of each puff of heated cigarette, extracting and concentrating by using a solvent, and detecting the puff-by-puff stability of the blueberry-flavored heated cigarette by using a deuterated reagent solvent. Nuclear magnetic hydrogen spectrums of corresponding samples are obtained through the nuclear magnetic resonance technology, and the similarity of spectrograms of all the samples is compared through information such as chemical shift, peak height and peak area on nuclear magnetic resonance hydrogen spectrum fingerprints, so that the puff-by-puff stability of the blueberry-flavored heated cigarettes is measured. The method is accurate and efficient, and is suitable for puff-by-puff stability analysis and detection of the blueberry-flavored heated cigarettes.

Description

technical field [0001] The invention relates to the field of detection of novel tobacco heated cigarettes, and more particularly relates to a method for detecting the puff-by-puff stability of blueberry-flavored heated cigarettes by using hydrogen nuclear magnetic resonance spectroscopy. Background technique [0002] In recent years, new types of tobacco have received widespread attention, among which heated cigarettes (HTP) are considered to be more acceptable to consumers because of their sensory experience closest to traditional cigarettes. Heated cigarettes have attracted many tobacco product consumers due to their advantages and characteristics such as less harmfulness, high safety, and better meeting the physical and psychological needs of smokers, showing a good momentum of development in the international market. [0003] Currently, there are various flavors of heated cigarettes, among which blueberry-flavored heated cigarettes are a product that appeared earlier and...
