摘要： The present disclosure belongs to the technical field of food processing, and in particular relates to a rapid and non-destructive quantitative evaluation method for taste characteristics of fried rice. The method includes three steps: constructing a quantitative model of seasoning for the fried rice, constructing a model for identifying types of materials of the fried rice, and performing quantitative characterization of the taste characteristics of the fried rice. The quantitative model of the seasoning is established based on sensitivity of a spectral signal to changes of the content of seasoning liquid. An analytic equation of key parameters of the quantitative model of the seasoning is established according to characteristics that the total amount of the seasoning in finished fried rice is equal to the total amount of the seasoning added during frying of the fried rice. The quantitative model of the seasoning is rapidly constructed by solving the equations.

摘要： A method and a device for detecting plastic foreign objects with low chromaticity difference in shredded tobacco through online pulse spectral imaging are provided. The method includes three steps: negative pressure thin-layer loading of shredded tobacco, pulse line-scanning identification of shredded tobacco, and positive pressure online elimination of foreign objects. Loose shredded tobacco is formed into a fixed and continuous thin layer on a surface of a conveying cylinder under the effect of a negative pressure adsorption force. The surface of the conveying cylinder is coded by areas. An LED linear array light source containing characteristic wavelengths of plastics with low chromaticity difference emits optical pulses, and a line-scanning camera is used to obtain characteristic signals of the plastic foreign objects with low chromaticity difference efficiently in real time.
