Abstract

The invention relates to a method for measuring the pectin content of paper-making reconstituted tobacco by a near-infrared diffuse reflection spectrum technology, belonging to the technical field of paper-making reconstituted tobacco. The method mainly comprises the following steps: (1) collecting a sample; (2) acquiring the original spectrum; (3) measuring the reference value of the sample; (4) selecting and pretreating a calibration sample set and a verification sample set; (5) establishing a point-line-surface (PLS) conceptual model; and (6) carrying out model validation. According to the method, the PLS conceptual model for measuring the pectin content of the paper-making reconstituted tobacco products is established by the near-infrared technology; the method has the advantages of being rapid in detection speed, high in accuracy, good in reproducibility and the like, and has an important assisting function for the researches such as reducing the tar and harmful components of cigarette products, improving smoking quality, etc.

Description

technical field [0001] The invention belongs to the field of reconstituted tobacco leaves by a papermaking method, and in particular relates to a method for measuring pectin in reconstituted tobacco leaves by a papermaking method using a near-infrared diffuse reflection spectrum technique. Background technique [0002] Papermaking reconstituted tobacco is an important raw material in cigarette production. Adding an appropriate amount of reconstituted tobacco to shredded tobacco can not only improve the physical properties and chemical components of cigarettes, improve the smoking safety of cigarettes, but also make full use of tobacco resources and reduce costs. At present, the reconstituted tobacco leaves of the papermaking method have problems such as high irritation and heavy woody gas, which affect its addition amount and use effect in cigarette products. The pectin content accounts for about 10%~13% of the total mass of reconstituted tobacco leaves. During pyrolysis, al...
