| Abstract:
Production of lipids is inadequate in several parts of the world, particularly in developing countries, where the shortage is a challenge to food scientists to seek new plant sources of high-oil content to overcome this. Peach kemels have a 49.58 % lipid content. The properties of oil extracted from peach kernels were: specific gravity, at 20°C, 0.914; refractive index 1.4692; acid number 108.5; peroxide number 0.72; iodine number 104; saponification number 186; unsaponifiable matter 0.85 %; colour 13 yellow to 2 red; freedom from hydrocyanic acid. Fractionation of fatty acids indicated the presence of the following acids: palmitic, arachidic, palmitoleic, oleic, linolenic, gadoleic and eicosatrienoic.
With regard to sterols, four fractions were identified as: cholesterol, 5 The oil extracted can be considered a semi-dry oil and can be used for many purposes. | |
