Reused Plant Fried Oil: A Case Study with Home-Made Soaps

The study aimed to analyze the possibility of waste frying oil utilization in home-made soap production. Soaps were made from unheated and fried rapeseed, sunflower palm oils that had total polar material (TPM) values up 24%. Physicochemical microbial analyses performed on produced samples check their quality. hardness increased with degradation level rapeseed oils, opposite findings obtained for sunflower-made soaps. highest malondialdehyde (MDA) contents recorded oil-made samples, maximum 6.61 µg/g, lowest 0.94 µg/g. antimicrobial assessment showed no significant (p > 0.05) differences between control soaps TPM value. Gram-positive bacteria (methicillin-resistant Staphylococcus aureus: MRSA) most sensitive chosen microorganisms, compared Gram-negative yeasts. results did not show exact experimentally or oils; these highlight potential production this byproduct.
