Abstract:

High consumption of poultry meat in the country leads to a considerable amount of poultry sleeves (skin along with feathers) as waste, which causes serious environmental problems and loss of valuable nutrients. Skin is one of the most underutilized poultry byproducts and a good source of quality fat. The present study was done to prepare pet soap utilizing rendered poultry skin fat from deserted poultry sleeves. Chicken skin fat (CSF) was obtained from de-feathered poultry skin by dry rendering (70°C, 2 h); wet rendering (70°C, 2 h) and microwave rendering (low microwave power for 6 min). The rendered poultry skin fat was then utilized for preparation of pet soap. The sodium hydroxide requirement for preparation of pet soap was standardized and the process for its preparation was optimized based on BIS standards. There was no significant difference (P>0.05) in the Yield, pH, Free alkali content, Total alkali content and Foam stability of soap prepared from CSF extracted by dry, wet or microwave rendering. However, the Leathering/washing power, Cleansing power and Total fatty matter (TFM) content were significantly higher (P<0.05) in soap prepared from microwave rendered fat. In addition, Free fatty acid value, Peroxide value and MDA value were significantly higher (P<0.05) in wet rendered than dry or microwave rendered fat soap. Hence, the rendered poultry skin fat could be a good base material for preparation of utility pet soap and microwave rendered CSF produce best quality soap.
