Business Process

Starmilk plants are well equipped with latest & advanced processing facilities, having a total production capacity of 100,000 lpd (litres per day). The milk variants produced and processed here are standardized, homogenized and pasteurized. Then, these are packaged in pouches for final distribution to the end consumers through a well organised network of distributors, dealers and retailers. The technology and equipments used in the production process are reliable, safe and are of approved qualities. In justification to our aim to provide Premium Quality Milk & Milk Products, each product sample goes through a proper & stringent quality check before they are set out for distribution and final consumption.

Milk Procurement

We procure milk on daily basis from the different districts in West Bengal. In our aim to deliver best quality of milk to our consumers, we collect milk twice a day after stringent checking of the necessary quality parameters at all the collection points itself. We have a strong association with well trained farmers, who maintain good food habits, for the good health of their cattle force, and in turn get & provide us good quality of cow & buffalo milk. We are taking a pledge to assure our associated farmers that -

The Company vehicles collect the Raw Milk from different Procurement Centers nearby to milk producing villages & our BMC’s and then delivered at our BMC’s (Bulk Milk Chillers), situated around these milk producing villages. Here, at our BMC’s, we maintain proper quality control checks & tests of the milk so collected, to ensure fresh quality of milk to be used in processing. From our BMC’s, again this tested milk is being transported to our main plant through insulated milk tankers. Here, the milk undergoes different processes in order to make it free from all impurities, harmful bacteria and other pathogens. The company undertakes pasteurization and homogenization of milk to get double toned milk, toned milk, standardized milk, cow milk and full cream milk. In order to maintain and ensure quality of this packaged milk, the whole lot is then stored under required cooling/refrigeration system before the delivery is effected in the market.

Quality Control

Our quality checking and testing parameters for Raw Milk:

  • Organoleptic Test by five senses- It permits rapid segregation of poor quality milk at the milk receiving platform itself. No equipment is required, but the milk grader must have good sense of sight, smell and taste.
  • Adulteration Check- It is done to find adulterations in the milk like Sugar, Salt, Starch, Urea, Soda, H2O2, Vegetable fat, Water etc.
  • P.H & Acidity Test
  • Specific Gravity Test
  • Fat, S.N.F & T.S % Calculation- It is being done to estimate the level of Total Solid Contents in the milk including the FAT % and C.L.R.
  • R.M.Value Test- It determines the Reichert–Meissl value of milk fat to restrict Fat Adulteration.
  • B.R.Test- It is being done to determine Fat Adulterations in milk through Butyro Refractometer Reading.
  • Heat Durability Test

Our quality checking & testing parameters for Pasteurized Milk:

  • Shelf Life Duration Test
  • Phosphatase Test
  • Creamy Index Test
  • Freezing Point Osmometry of milk is done to determine additional water content.

Microbiological Tests for Milk:

  • M.B.R.Test- ( Methylene Blue Dye Reduction Test)- It is used as a quick method to assess the microbiological quality of raw and pasteurized milk.
  • Standard Plate Count (SPC)- It is aerobic plate count of total colony forming units of bacteria per milliliter or gram of raw, processed liquid and dry dairy products.
  • Direct Micro Count (DMC)- It is Direct Microscopic Count examination of stained preparation of milk or certain other dairy products, to identify and enumerate the number of bacterial clumps present.
  • Coliform Analysis-


The products are properly packaged in durable and attractive pouches of 200ml, 500ml and 1000ml. The products are distributed to the end consumers in West Bengal via different channels of distribution like Distributors, Dealers and Retailers and through a dedicated logistic team.
