基于颜色参数变化的青花菜叶绿素含量预测模型
A Prediction Model for Chlorophyll Content in Post-harvest Broccoli Based on Color Parameter Changes
摘要
Abstract
In order to explore the relationship between chlorophyll content and color change of post-harvest broccoli during storage,a prediction model for chlorophyll content was established based on color parameter changes.Freshly harvested broccoli was stored at different temperatures（273,278,283,293 K and 303 K）,and the color parameter-a/b value and chlorophyll content of broccoli were determined.Kinetic models of-a/b value and chlorophyll content with respect to storage time and temperature were established on the basis of Arrhenius equation.In addition,a prediction model for chlorophyll content based on-a/b value was further developed according to the linear relationship between chlorophyll content and-a/b value.Moreover,the prediction model for chlorophyll content based on-a/b value was validated using broccoli stored at 275,280,285,295 K and 305 K with a relative prediction error of 4.31%.The chlorophyll content of broccoli can be accurately predicted at the storage temperature from 273 K to 305 K using this prediction model.Therefore,the prediction model is acceptable for applying the color parameter-a/b to evaluate broccoli quality.关键词
