Stearin is used as a hardening agent in the manufacture of candles and soap.
Similarly What is IV in palm oil? Some of the indicators used to characterize palm oil are iodine value (IV) and slip melting point (SMP). The IV measures the degree of unsaturation or double bonds of oils and fats. It also indicates the ease of oxidation of oils and fats (Guided Wave Incorporated, 2008).
What is palm oil stearin? Palm stearin is the solid fraction of palm oil that is produced by partial crystallization at controlled temperature. It is a stearin in the sense of stearins and oleins being the solid and liquid fractions respectively of fats and oils; not in the sense of glyceryl tristearate.
Additionally, What is the difference between palm stearin and palm oil?
Palm stearin is the harder fraction of palm oil, containing a higher proportion of saturated fatty acids and TAGs with a higher melting point of 48–50°C. The palmitic acid content ranges from 49 to 68% and oleic content from 24 to 34% (Sue, 2009).
What is the difference between palm olein and palm stearin?
After fractionation the liquid portion is called “palm olein”, which is commonly bottled and sold as cooking oils. The solid fat portion is called “palm stearin” and it is commonly used to formulate trans-free fats such as margarine, shortening and vegetable ghee.
What is an acrolein test? Acrolein test is used to detect the presence of glycerol or fat. When fat is treated strongly in the presence of a dehydrating agent like potassium bisulphate (KHSO4), the glycerol portion of the molecule is dehydrated to form an unsaturated aldehyde, acrolein that has a pungent irritating odour.
What is cloud point in palm oil? The cloud point of the hydrogenated oil is about 20 °C, slightly worse than FAME. Cloud point is the temperature at which wax (paraffin) begins to separate when oil chilled to a low temperature, and it serves as an important indicator of practical performance in automotive applications in low temperatures.
What is olein and stearin? Palm stearin is the solid fraction of palm oil that is produced by partial crystallization at controlled temperature. It is a stearin in the sense of stearins and oleins being the solid and liquid fractions respectively of fats and oils; not in the sense of glyceryl tristearate.
What is the composition of palm oil?
Palm oil, like all fats, is composed of fatty acids, esterified with glycerol. Palm oil has an especially high concentration of saturated fat, specifically the 16-carbon saturated fatty acid, palmitic acid, to which it gives its name. Monounsaturated oleic acid is also a major constituent of palm oil.
What is the chemical formula for palm oil? Glycerides, palm-oil mono-and di-, hydrogenated, 3-oxododecanoates

What is the difference between stearin and stearic acid?
Unlike Stearic Acid, Palm Stearin is not an acid, in fact it has a PH very close to neutral, hence, special handling precautions are not required. Palm Stearin’s consistencies may vary from being soft as butter to hard and brittle as stearic acid.
What is CP in palm oil? Most palm based cooking oil is RBD Palm Olein. there are three distinct grades with different specifications. The important detail is the Cloud Point .. shown as CP. Some countries will use CP6, some countries use CP8 or CP10.
What is Sudan Red test?
the detection of Sudan Red food dye, a potential carcinogen that. has been the focus of numerous product recalls. The aim of the test, says the research firm, is to ensure that current product inventories or products that are being purchased are free from these illegal colorants.
How do you test for a lipid?
To test for the presence of lipids, you would carry out the emulsion test. To do this, you take the sample and mix it with equal volumes of ethanol and water followed by shaking. A cloudy white emulsion will form if lipids are present. If lipids are absent, no emulsion will form.
How is glycerol tested? Test Principle
The glycerol reacts, by an enzyme, with a phenolic derivative and induces the formation of a complex pink color whose intensity, measured at 505 nm, is directly proportional to the concentration of glycerol in the sample. The result is expressed in g / L.
What is pour point of diesel? Pour point is an important quality specification for diesel fuels. Specifically, it is a measure of the tendency of a fuel to become more viscous and resist flowing when cold.
What determines smoke point?
Smoke point values can vary greatly, depending on factors such as the volume of oil utilized, the size of the container, the presence of air currents, the type and source of light as well as the quality of the oil and its acidity content, otherwise known as free fatty acid (FFA) content.
What temperature does palm oil melt? Common oils from animals or plants and their melting points.
| Oil | Melting Temperature ( o C) |
|---|---|
| Olive Oil | -6 |
| Palm Kernel Oil | 24 |
| Palm Oil | 35 |
| Peanut Oil | 3 |
What is palm kernel stearin?
Palm kernel stearin is the high premium product from the fractionation of palm kernel oil. The sharp solid fat content (SFC) profile indicates its suitability for use in confectionery fats. The products produced in Malaysia are consistent in quality and properties.
What is palm super olein? Palm olein is the liquid fraction obtained during fractionation of palm oil, which involves crystallization under controlled temperature and removal of crystals by filtration. Palm olein contains higher amounts of oleic (39–45%) and linoleic acids (10–13%) compared to palm oil (Siew, 2002).
