Fig. peroxide, refractive index and free fatty acids values increased in the order soybean oil>groundnut oil>palm oil>palm kernel oil, while their iodine values were.

Many materials have a well-characterized refractive index, but these indexes depend strongly upon the frequency of light. Standard refractive index measurements are taken at the "yellow doublet" sodium D line, with a wavelength of 589 nanometers. There are also weaker dependencies on temperature, pressure/stress, etc., as well on precise material compositions (presence of dopants, etc.); for

According Sunflower oil is the non-volatile oil pressed from the seeds of sunflower ( Helianthus annuus). Refractive index (25 °C), ≈1.4735 palm kernel oil · Peanut oil The peroxide values and refractive indices of palm olein, sesame oil and sunflower oil were evaluated before deep frying. The vegetable oils were used to frying

In general, the refractive index of palm oil measured at 50°C is in the range of 1.449–1.455 (Firestone, 2006). The Chemical Properties of Palm Oil and Its Components. Palm oil and its components are increasingly used in foods such as cooking oils, margarines, shortenings, and confectionery products.

Refractive Index (RI) The refractive index of oil is a measure of the extent to which a beam of light is refracted on passing from air into oil. This can be a useful characteristic in that the determination is carried out with ease, speed and precision, using small amounts of the oil. The RI can also be used for establishing oil purity. Refractive index at 40 o C: 58.0 to 60.5; or . 1.4646 to 1.4662: 2. Saponification value: 168-177: 3. Iodine value: 96-112: Polybromide test shall be Negative: 4. Unsaponifiable matter: Not more than 1.2 percent by weight: 5. Acid value: Not more than 6.0: 6. Bellier test (Turbidity temperature – Acetic acid Method) 23.0°C to 27.5°C: 7. Test for Hydrocyanic Acid: Passes the test In general, the refractive index of palm oil measured at 50°C is in the range of 1.449–1.455 (Firestone, 2006). The Chemical Properties of Palm Oil and Its Components. Palm oil and its components are increasingly used in foods such as cooking oils, margarines, shortenings, and confectionery products. The densities and the refractive indices of seven samples of neutralized, hydrogenated palm olein and six fractions from palm oil were determined. It was found that both the density and the refractive index decreased linearly with increasing temperature over the range 30°C to 80°C. Palm kernel oil and palm olein were blended (100 to 100 v/v) and fatty acid composition, iodine value and refractive index determined. Results indicate that palm kernel oil is a lauric fat with high lauric (48.33%) and myristic (15.78%)
