Abstract
Grease amount inside a food can influence humans health. Grease amount in a food has correlation with cholesterol amount which could lead to various diseases, as stated in Regulation of the Minister of Health number 30, year 2013, clause number 4, and verse number 2 which said that more than 67 grams of total fat per day for each person leads to hypertension, stroke, diabetes, and cardiac arrest risk. This research purposed to characterize wasted grease amount of food towards various spinning cycle of grease filtering machine. Various methods could be implemented to decrease the grease amount in a food, potato chips. Using the influence of centripetal force by applying motors spinning rate became the method which was implemented in this research. Determining volume of wasted grease amount was done by scaling food before grease filtering process then re-scale after filtering process was done. In order to find out the volume of wasted grease was through a division between the mass of wasted grease with the density of grease which is 0.8 g/cm3. Examination result shows potato chips grease amount decreased up to 10%. Wasted grease amount towards linear spinning rate with 0.99 determination coefficient graph also found based on experiments implementation. The result of research determines for each 1 rpm increase from spinning cycle, the numbers of wasted grease amount is 10.9 grams.
