Abstract

The invention relates to a method for detecting physical and chemical indexes of reconstituted tobacco by a near infrared spectrum detection paper making method, which comprises the following steps of: carrying out the detection of the physical and chemical indexes on collected samples one by one by a standard method to obtain quantitative reference data; scanning and collecting spectrums of all the samples, carrying out spectrum preprocessing and eliminating the influence of noise and baseline drift; then corresponding spectrum data to the reference data of all physical and chemical indexes obtained by the standard method one to one and establishing a quantitative model by a partial least square method and mutual verification; carrying out accuracy and reproducibility inspection and then storing the quantitative model in a computer. When the physical and chemical component content of the reconstituted tobacco product samples to be detected needs to be detected, the near infrared spectrum data of the samples to be detected are scanned and collected, and the physical and chemical indexes of the samples to be detected can be analyzed by calling the quantitative model. The method has rapid and accurate detection and low analyzing cost without damaging the analyzing samples and pollution.

Description

technical field

[0001] The invention relates to a method for detecting physical and chemical indicators of tobacco, in particular to a method for detecting conventional physical and chemical indicators of reconstituted tobacco leaf products by papermaking. Background technique

[0002] Paper-making reconstituted tobacco leaves, also known as paper-making tobacco flakes, use tobacco stems, smoke foam, and low-grade tobacco leaves as raw materials. After leaching and concentration, beating, papermaking, coating and drying, etc., they are produced by comprehensive utilization of extraction, separation, papermaking, and recombination technologies. High-tech tobacco products that are close to or even superior to natural tobacco leaves. Tobacco sheet has the characteristics of low density, high filling value, good flexibility and processing resistance, high filamentation rate, good combustion performance, low tar release and strong product plasticity. The quality of reconstituted...
