Determining fatty acids and halal authentication of sausage
Sausages are instant food that requires the halal attention for a Muslim. In general, nonhalal issues are usually associated with pig derivatives. One of the pig derivates is lard that can be analyzed using GC-MS via a transesterification catalyzed with a base catalyst like sodium methoxide 2%. This study indicated that pork sausage has different fatty acids compared with beef sausage. The pork sausage contained the dominant fatty acids such as palmitic acid (37.75%), myristic acid (22.24%), oleic acid (25.29%), and lauric acid (8.46%). Whereas, beef sausage has the dominant fatty acids of palmitic acid (42.31%), oleic acid (20.19%), stearic acid (10.92%) and myristic acid (7.66%). The commercial sausages 1, 2, and 3 have similar dominant fatty acids such as palmitic acid, oleic acid, stearic acid, and myristic acid compared with fatty acid types in beef sausage. The discriminant analysis also showed that the beef sausage is separated location from pork sausage and all samples are not containing the pork or lard because they are far away from pork sausage.
