基于休闲豆干的热量成分检测及检测模型校正
The correction of calory answer testing model based on leisure dried Tofu
摘要
Abstract
Using the market sale leisure dried bean curd as material,determinated the protein content in leisure dried tofu by Kjeldahl method,the moisture content in rapid moisture tester and the fat content with Soxhlet extraction method.Then using the Calory Answer to determinate the contents of protein,fat and moisture,using the mathematical analysis method to correct the detection model,and then the corresponding correction model is obtained.After the calibration,the model of the Calory Answer respectively isyp =1.15x,yw =0.85x,yf =0.65x,these correction model were suitable for the leisure dried tofu that the protein content,moisture content and the fat content ranges in 22.80～27.30 g/100 g,36.12～51.59 g/100 g and 7.42～ 14.80 g/100 g,respectively.The protein content after correction of absolute error is decreased by 1.44,the average error rate is reduced by 6.23 ％;moisture content of absolute error is reduced 6.77,the average error rate reduces 14.71％;fat content of absolute error is decreased by 4.49 and the average error rate reduces 45.74％.After the correction,the corrected Calory Answer can quickly and accurately detect the content of protein,moisture,fat,and provides a new approach for the rapid detection of protein,moisture,fat content in the leisure dried tofu.关键词
