Why should you use BS 4938-1-Determination of dirt content of milk?
Dirt is defined as any insoluble material, e.g., vegetable matter from dung, feed or bedding and inorganic matter from soil or dust, that has entered milk after the milk has left the udder. Dirt content is the volume, in microlitres, of moist dirt per litre of milk (i.e., 4L/L).
BS 4938-1 provides you with guidance on apparatus, preparation of test sample, procedures, expression of results, method of calculation, precision, test report, etc.
The reference method and procedure provided by BS 4938-1 assist you in the determination of dirt (moist), by centrifuging followed by chemical treatment of the deposit obtained, as microlitres per litre of milk, improving the quality and subsistence of milk and ensuring milk is free from contaminations.
With obedience and compliance to BS 4938-1, you can enhance milk’s effectiveness and efficacy and manufacture a standardized high-quality product
