초록
Biodiesel, which is most commonly derived from vegetable oils, and waste cooking oil, is an alternative to petroleumbased fuels. Since vegetable oils are also an important commodity in the food market, their prices are expected to increase substantilly given their broadening usage. Hence, waste animal fats are being considered as a promising cheap alternative feedstock for biodiesel production. Animal oil is extracted mainly from rendered tissue fats derived from livestock animals like pigs, chickens and cows. The objective of this study is to study the effects of extraction method of animal fatty tissues. Our extraction method is composed of high temperature extraction (100～140℃, 0.10 Mpa) is first applied to 40 kg of fat tissue for 2～3 h. Following this, the second step (70～100℃, -0.09 MPa), is applied for 60 min. This method resulted in a recovery of 69.4% of the total fat oil of the tissue. Major fatty acids from the extracted animal oils were palmitic, stearic, and oleic acid. Average contents and ranges of saturated fatty acids (SFA) palmitic acid and stearic acid, were 25.8% (23.5～28.9%), and 11.4% (7.8～14.4%), while those of unsaturated fatty acids (USFA) oleic acid and linoleic acid were 46.4% (41.6～51.7%) and 3.1% (1.4～8.1%), respectively.
Abstract
Biodiesel, which is most commonly derived from vegetable oils, and waste cooking oil, is an alternative to petroleumbased fuels. Since vegetable oils are also an important commodity in the food market, their prices are expected to increase substantilly given their broadening usage. Hence, waste animal fats are being considered as a promising cheap alternative feedstock for biodiesel production. Animal oil is extracted mainly from rendered tissue fats derived from livestock animals like pigs, chickens and cows. The objective of this study is to study the effects of extraction method of animal fatty tissues. Our extraction method is composed of high temperature extraction (100～140℃, 0.10 Mpa) is first applied to 40 kg of fat tissue for 2～3 h. Following this, the second step (70～100℃, -0.09 MPa), is applied for 60 min. This method resulted in a recovery of 69.4% of the total fat oil of the tissue. Major fatty acids from the extracted animal oils were palmitic, stearic, and oleic acid. Average contents and ranges of saturated fatty acids (SFA) palmitic acid and stearic acid, were 25.8% (23.5～28.9%), and 11.4% (7.8～14.4%), while those of unsaturated fatty acids (USFA) oleic acid and linoleic acid were 46.4% (41.6～51.7%) and 3.1% (1.4～8.1%), respectively.
