Quality control in the Dairy Industry is essential to ensure that the consumer, the ultimate recipient of the products gets in an acceptable condition without adulteration of any kind and thereby safeguarding their health and aesthetic sense.

The Quality Control laboratory in Madurai Dairy is equipped to analyse and evaluate the quality of milk and milk products both chemically and bacteriologically.

Agmark and weights and measure Act.

The milk on its receipt from the various cooperative societies is accepted by screening organoleptically (colour taste flavour etc.) and subjected to chemical and bacteriological analysis. As we make payment on the basis of quality, milk from each source is tested for its fat and solid non fat content. In respect of Buffalo milk, the payment is made on the basis of kilo fat and for cow milk on total solids basis.

The raw milk reception is computerized and the farmers are made known, the milk rate and Quantity of milk supplied on the next day itself. The milk cost payment is also done by computerised billing to avoid delay. The bulk raw and pasteurized milk from chilling center and other Districts are subjected to Metheyline Blue Reduction test to assess the hygienic quality and keeping quality in addition to the fat and SNF, Acidity, Roselic Acid test (for Neutralizer) etc. If the quality of incoming milk is found to be poor, the fact is being immediately brought to the notice of the production personnel to take immediate steps to process the milk in priority and informed the source concerned to take immediate remedial measures to rectify the problem.

The milk thus received is pasteurized, Homogenized standardized and packed for marketing. During these stages, series of quality check is being carried out to check the efficiency of the pasteurization Homogenization correctness of the standard and its keeping quality.

The various by products like butter, skim milk powder, ghee, butter milk, curd, flavored sterilized milk, khoa, mysorepa and Aavin Jamun are subjected to strict quality control checks at different levels of production and storage and all concerted efforts are being taken to ensure that the products thus manufactured confirm to the standards prescribed by the prevention of food adulteration act, Indian Standard and Agmark.
