OBJECTIVE To understand the current status of protein,fat,carbohydrates,energy,vitamins,minerals and other contents in common dishes of large,small,and medium-sized restaurants in Shandong Province.METHODS From July to October 2021,90 Shandong cuisine dishes were collected from 9 large,medium,and small restaurants in Shandong Province.One dish was collected from each restaurant,and samples from different types of restaurants were mixed as one sample.The content of nutrients and their carbohydrate and energy levels were detected and calculated.RESULTS The median fat and protein content detected in the 90 dishes collected were 7.7 and 6.8 g/100 g,respectively.The calculated median values of energy and carbohydrates were 528 kJ/100 g and 5.4 g/100 g,respectively.The energy supply ratio of carbohydrates per 100 g of dishes was 17.2％,fat was 55.3％,and protein was 21.4％.The content of vitamin A,vitamin B1,vitamin B2,vitamin C and vitamin E was trace(tr)-26 700 µg/100 g,tr-0.12 mg/100 g,tr-0.40 mg/100 g,tr-56.5 mg/100 g and tr-5.31 mg α-TE/100 g.The medium number of dishes and potassium content was 375 and 219 mg/100 g.The detection rate of trans fat acid was 81.1％,and the median content was 0.06 g/100 g.CONCLUSION The energy supply ratio of protein and fat in dishes is relatively high,while the energy supply ratio of total carbohydrates is relatively low.The sodium content is high,showing the characteristics of high sodium and low potassium.Vitamin,especially vitamin B1 and vitamin B2,has a low content.
