The dairy industry is experiencing rapid growth worldwide and is forecasted to reach a value of $1,032 billion by 2024. India ranks third in cow milk production, following the EU and the United States. According to Nielsen’s report, approximately 73% of consumers worldwide prefer companies that provide clear information about the origin and production methods of their products.
Milk is a nutritious food which has a short shelf life and is a breeding ground for bacterial pathogens. Milk processes help in stretching the shelf life and thereby reduce foodborne illness. Production and processing are the two main stages in the dairy supply chain followed by storage and distribution. The dairy product supply chain is a long and complex one with its own challenges. 
The journey begins on dairy farms where cows are raised and milked. Dairy farmers focus on animal care, nutrition, and health to ensure high-quality milk production. Cows graze on pasture or are fed a balanced diet to support their health and milk productivity.
An estimated 90% of milk is produced by small hold dairy farmers. The dairy animals are fed on fodder, residue of crops and grass. Dairy farming encompasses breeding, rearing and welfare of cattle for production of milk. The principles of breeding help in milk production. Pasture is the natural feed for cattle. Other feeds are also supplemented. Herd management and animal welfare is very important. Disease outbreaks are common and proper veterinary services are mandatory.
Once the cows are milked, the raw milk is collected and stored in refrigerated tanks on the farm or transported to a nearby dairy processing facility. Quality testing may be conducted to ensure the milk meets regulatory standards for safety and freshness.
The producers are usually dispersed in rural areas and the logistics of linking them to markets is important. Considering the perishable nature of milk, streamlined collection and transportation of milk is vital. Milk is usually transported in cans or tankers and collected at specified collection centers. Milk collectors transport milk to processing centers, local markets, shops or hotels.
At the dairy processing facility, the raw milk undergoes various processing steps to produce a range of dairy products such as milk, cheese, yogurt, and butter. Processing may involve pasteurization to eliminate harmful bacteria, homogenization to ensure uniform consistency, and separation to remove excess fat or cream.
Milk that arrives at processing units are stored in bulk chillers at a temperature below 40 F. The milk is then subjected to a series of quality checks to ensure that the milk has been cooled and is bacteria free. It is tested for milk fat, protein and tested for adulterants and residues. The milk is rejected if it does not satisfy the quality checks.
Pasteurization involves a heat treatment process that kills the pathogens in milk and increases its shelf life. Homogenization of milk is carried out to reduce the size of fat and give the milk the color and texture. Milk can be further processed to give the other byproducts like butter, cheese and yoghurt.  
Processed dairy products are packaged into containers suitable for retail sale or distribution. Packaging materials may vary depending on the product and market preferences, but they typically include bottles, cartons, tubs, or pouches.
Packaged dairy products are distributed to retail outlets such as grocery stores, supermarkets, convenience stores, and specialty shops. Distribution channels may involve wholesalers, distributors, and logistics companies responsible for transporting products from processing facilities to retail locations.
The homogenized and pasteurized milk are packaged into cartons and distributed to supermarkets and the end consumers. The cold storage conditions need to be maintained. The byproducts like cheese and yoghurt are often packed in customized packages depending on extra flavors added.
Consumers purchase dairy products from retail outlets for consumption at home or on the go. Retailers play a crucial role in merchandising, stocking, and promoting dairy products to meet consumer demand and preferences.
Finally, consumers enjoy dairy products as part of their daily diet, whether it’s a glass of milk with breakfast, a slice of cheese on a sandwich, or a serving of yogurt as a snack. The consumption of dairy products provides essential nutrients such as calcium, protein, vitamins, and minerals that contribute to overall health and well-being.
Overall, the “grass to glass” story highlights the interconnectedness of various stakeholders in the dairy supply chain, from farmers and processors to distributors and consumers. Each stage plays a critical role in delivering safe, nutritious, and delicious dairy products to consumers worldwide.
The dairy industry is a vital component of the global food system, encompassing the production, processing, and distribution of milk and dairy products. It plays a significant role in providing essential nutrients to consumers worldwide, contributing to food security and economic development in many regions. From milk and cheese to yogurt and butter, dairy products are consumed by people of all ages and cultures, making the industry indispensable to the agricultural sector.
Traceability and sustainability have become increasingly critical aspects of the dairy supply chain due to growing consumer demand for transparency, ethical practices, and environmental responsibility.
