Abstract

Fatty Acids Profile and Medium Changes Fatty Acids (MCFA) on Coconut Fresh and Coconut Milk (Cocos nucifera L.)ABSTRACT. This study was conducted to determine the fatty acids profile and medium changes fatty acids on coconut fresh and coconut milk. The fatty acids content of coconut fresh and coconut milk of saturated fatty acids (120.88- 84%) consist of C6:0, C8:0, C10:0, C12:0, C14:0, C16:0, C18:0. The monounsaturated fatty acids present was palmitoleic acid (C6:1c9) and oleic acid (C18:1n9) amounting to 15.7-16.2%, respectively. While linoleic (C18:2n6) was the major polyunsaturated fatty acids, amounting to 2.20-3.40%. The total medium changes fatty acids (MCFA) in coconut fresh and coconut milk were 70.0% and 67.5%.

Abstract

Study of The Primary bound Water Fraction, Secondary and Tertiery in Coconut (Cocos nucifera L.)ABSTRACT. Critical moisture and water activity of coconut (Cocos nucifera L.), were analyzed for the first and second critical points of transition among the primary, secondary and the tertiery  bound water fraction in the coconut. It was found out that the first critical points of moisture content and water activity were Mp of 5.22% db and ap of 0.30 respectively. The second ctitical points were water content Ms 12.4% db and water activity as 67% respectively. Coconut sample in the primary bound water fraction (represented by moisture content at 5.22% db), was stable in colour and appearance, but slightly rancid due to molecular mobility of the liquid oil content. The sample in the secondary bound water fraction (represented 12.4% db), has a colour change to darker brown, and in the tertiary bound water fraction (represented 90.5% db), mold growth appeared on the 12 days storage. Coconut indicated and Intermediate Moisture Food (IMF), because limited shelf life for few days at room temperature.
