This study was undertaken to analyze the factors influencing on the pollution loading in the cooking waste water.The influence of wiping the tableware appliances, the difference in menu style (Japanese, Western and Chinese style dishes), the energy ratio and the effect of soap use on the Chemical Oxygen Demand (COD) and Biochemical Oxygen Demand (BOD) loadings in terms of g/1, 000kcal of the dish were determined. Tow-way ANOVA and the multiple regression analysis were used for statistical analysis. The major results obtained were as follows: 1) 44% of the COD and 54% of the BOD loadings in the cooking waste water were significantly reduced by wiping the tableware appliances. 2) The difference in menu style (Japanese, Western and Chinese style dishes) had no effect on the COD and BOD loadings. 3) The composition of energy intake (the percentage of energy obtained from protein, fat and carbohydrate) had no effect on the COD and BOD loadings. 4) The ues of soap was tended to reduce by wiping the tableware appliances however the soap use had no effect on the COD and BOD loadings.
