BIS standards for Milk and Milk Products: An Extensive Outlook

BIS standards for Milk and Milk Products

The Indian Government has underpinned extensive guidelines for producer and exporter for milk & milk products which have been made a legal compulsion vide the Milk and Milk Product Order 1992.  As per this order, any individual/milk plant processing more than 100000 L/day or 500MT of milk powder annually needs to obtain consent from the registering authority working under the aegis of central authority. The primary goal of the order is to administer & escalate the supply of liquid milk of desired quality in the interest of the masses & also for governing the supply chain of milk and milk product.  In this blog, we will cast some light on the BIS standards for Milk and Milk Products.

In India, the Ministry of Health and Family Welfare has setup the nodal ministry for administering the food standards in India. Prevention of Food Adulteration Act 1954 (PFA) entails the guidelines regarding the food quality and safety at the national level

BIS standards for Milk and Milk Products

BIS standards for Milk and Milk Products have been outlined on the basis of the following parameters:

SPC (Standard Plate Count*), No standard has been introduced

Standard Plate Count* refers the measure of the total number of aerobic bacteria present in the milk products.

Coliform count butter has been maxed at 10/ ml to ensure optimal quality.

AGMARK* Standards

AGMARK* refers to a certification mark affixed on the agro-based commodities in India[1]. The product under AGMARK certification renders the assurance of quality and standards approved by the Directorate of Marketing & Inspection.

Conclusion

Milk is the widely consumed commodity in India and there are handful of companies that are involved in it production. The volume at which daily products are produced in our nation is beyond monumental. Hence, there is a need of a safety protocol that can ensure 100% hygine and quality of such products. BIS is doing a commendable job in this regard by incorporating relevant measures every now and then. Hope this detailed snapshot on BIS standards for Milk and Milk Products would provide you with adequate information. For clarification, please drop your message in the comment box.
