Performance evaluation of Malaysia Rubber Seed Oil (RSO) as future cooking oil

Abstract

Rubber plantation is one of the major commodities in Malaysia and the tree produces by product, which is rubber seed. Each rubber seed contain 40-50% oil and it can be extracted via chemical or physical process. In this research, the properties of pure refined rubber seed oil (RSO) was studied and compared with current Malaysia palm cooking oil (PMO). From the nutrient content, it indicates that in 100 g RSO, it contains 855 kcal calories, 0.5 g protein, 94.8 g fat and 0 g carbohydrate. In term of double bond content, the average value of the iodine content for RSO is 90g/100g RSO while PMO depict 55g/100 g PMO. Viscosity of RSO is slightly higher with 51.9 cP and 39 cP for PMO. Density figures same values with 0.92 g/cm³, whereas saponification value shows 220.88 mg KOH/g for RSO and 240 mg KOH/g for PMO.
