Abstract: Elateriospermum tapos seed (buah perah) is the one
of the rich sources of polyunsaturated fatty acids. It contains high
percentage of oleic acid which is the important component to develop
nervous system and also α-linolenic acid (ALA) which is the
precursor of omega-3 fatty acids series to synthesize
eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA).
However, there is less study about this valuable oilseed and exploit
its potential. Therefore, this paper is to assess the comparison of
physico-chemical properties and fatty composition of perah oil to
palm oil and soybean oil. From the comparison, perah oil shows low
peroxide value means it has good oxidative stability and also high
iodine values shows that it can be used in paint industry. The study
shown that perah oil is comparable to palm oil and soybean oil, so it
has high potential to be exploited in the oleochemical,
pharmaceutical, cosmetics and paint industries.
Abstract: Nuts are part of a healthy diet such as Mediterranean diet. Benefits of nuts in reducing the risk of heart disease has been reasonably attributed to their composition of vitamins, minerals, unsaturated fatty acids, fiber and phytochemicals such as polyphenols, tocopherols, squalene and phytosterols. More than 75% of total fatty acids of nuts are unsaturated. α- tocopherol is the main tocopherol isomer present in most of the nuts. While walnuts, Brazil nut, cashew nut, peanut, pecan and pistachio nuts are rich in γ- tocopherol. β- sitosterol is dominant sterol in nuts. Pistachio and pine nut have the highest total phytosterol and Brazil nut and English walnut the lowest. Walnuts also contain large amount of phenolic compounds compared with other nuts. Nuts are rich in compounds with antioxidant properties and their consumption can offer preventing from incidence of many diseases including cardiovascular.
