Purifying use of cooking oil

CHAPTER I INTRODUCTIONBackground of the Study Oil employ in prep foods is commonly derived from vegetables. provision oil is commonly used for hot up and oil used for frying is usually thrown away. The cycle of cooking oil also provides a form of revenue for restaurants,which are sometimes compensated by cooking oil recyclers for their used deep fryer oil. Cooking oil recycling also results in less used oil being given of in drains, which can clog sewage lines due to the build-up of fats.Statement of the Problem How to correct and reuse cooking oil for further usage? Objectives of the StudyThis investigatory hurtle determines the possibility of purifying used cooking oil using deposit method. The activated carbon was also used in the experiment to lodge in some dissolved substances in the oil. There were three different setups used in this study namely apparatus 1 ( repository was done once) Setup 2 (sedimentation was done twice) and Setup 3 (sedimentation was done thrice) . The purified oil was compared to commercial message oil in call of color, odor, and clearness using acceptability test. viscousness test was also done in the laboratory. 3.The means of the samples were compared and revealed that purified oil had no significant difference to commercial cooking oil in terms of color/clearness and odor as the result of the acceptability test. Therefore, sedimentation is a possible method of purifying used cooking oil.
