Physiochemical Properties and Fatty Acids Profiles of Oil from Musa Aluminata balbisiana

摘要

Banana peel wastes of Musa Aluminata balbisiana (MBS) which known as a waste, and often ignored was collected and subjected to approximate composition study. The study revealed that the peel contained 78.58% of moisture content and 0.57% of volatile content. Oil extraction of MBS was performed using soxhlet method was yielded a pale brownish oil at room temperature with extraction recovery of 62.42%. The oil was exhibited a density, specific gravity, refractive index and viscosity of 08502 kg/m3, 0.8536 kg/m~3, 1.47 and 3.29 cSt respectively. Physiochemical analysis shows that, the oil contained 2.64 of free fatty acids (FFAs), 0.77 g I_2/100 g of oil Iodine values (IV), 7.46 mgKOH/g of saponification value (SV), 0.52 mgKOH/g of total acid number (TAN). Fatty acids analysis showed that, the oil composed of 46% of saturated fatty acids (SFAs) and monounsaturated fatty acids (MUFAs) and 4% of polyunsaturated fatty acids (PUFAs). The fatty acids analysis exhibit a desirable properties to further developed as a lubricants or as a lubricant additives due to ability to provides surface protective film in tribological behavioral due to the higher percentages of SFAs.
