BS 684 is a British standard on methods of analysis of fats and fatty oils that discusses the determination of 1-monoglycerides and free glycerol contents in fatty oils to ensure animal and vegetable fats and oils are safe for consumption.
BS 684-2.42 is the forty-second subpart of the second part of the BS 684 series that specifies a method for the determination of 1-monoglycerides content and of free glycerol content consecutively on the same test portion.
BS 684-2.42 is applicable to animal and vegetable fats and oils and to interesterified products of oils, fats, and fatty acids with glycerol.
Note: BS 684-2.42 is not applicable when the sample contains
BS 684-2.42 on the determination of 1-monoglycerides and free glycerol contents in fatty oils is useful for:
Monoglycerides are a type of glyceride. They are made up of glycerol and one fatty acid chain. Glycerol is a small organic molecule with three hydroxyl (OH) groups, while a fatty acid consists of a long hydrocarbon chain attached to a carboxyl group. Mono- and diglycerides are emulsifiers, which means they help oil and water to blend. As a result, they are commonly used as food additives. Small quantities are often added to packaged and frozen foods to improve texture and stability, prevent oil from separating, and extend shelf life.
BS 684-2.42 provides you with guidance on apparatus, sampling, the procedure for preparation of test sample, extraction, determination of 1-monoglycerides, determination of free glycerol, expression of results, method of calculation and formulae, calculation of free glycerol content, test report, etc.
The methods and procedures provided by BS 684-2.42 assist you in the determination of 1-monoglycerides and free glycerol contents in fatty oils, improving the quality and subsistence of animal and vegetable fats and oils and ensuring animal and vegetable fats and oils are free from contaminations.
With obedience and compliance to BS 684-2.42, you can enhance animal and vegetable fats and oils’ effectiveness and efficacy and manufacture a standardized high-quality product.
BS 684-2.42:1989 supersedes BS 684-2.42:1986, which is withdrawn. BS 684-2.42:1989 table in 8.2 has been expanded to give a wider range of approximate masses of the test portion, and editorial modifications have been made as compared to BS 684-2.42:1986.
