Advanced manufacturing refers to the use of innovative technologies and processes to produce goods efficiently and effectively. In the context of milk and milk products, advanced manufacturing techniques can be used to improve the quality and safety of these products while reducing costs and increasing production yields.

Some examples of advanced manufacturing technologies used in the dairy industry include:

1. High-pressure processing (HPP): This is a non-thermal processing technique that uses high pressure to inactivate harmful bacteria and extend the shelf life of dairy products.
2. Membrane filtration: This process involves the use of membranes to separate different components of milk, such as proteins, fats, and lactose. This can be used to create products such as whey protein isolate and lactose-free milk.
3. Microbial cultures: These are used to ferment milk and create products such as yogurt, kefir, and cheese.
4. Spray drying: This is a process used to turn liquid milk into powder form, which can be used for a variety of applications, including infant formula and protein supplements.

Regarding COVID-19 and Fostac, Fostac is a training program developed by the Food Safety and Standards Authority of India (FSSAI) to improve food safety practices in the food industry. While Fostac is not directly related to COVID-19, it is important for food manufacturers to implement food safety protocols to prevent the spread of the virus through food products.

Food manufacturers should follow guidelines from regulatory agencies such as FSSAI and the World Health Organization (WHO) to ensure that their products are safe for consumption. This includes implementing hygiene and sanitation practices, providing personal protective equipment (PPE) for employees, and implementing social distancing measures in the workplace.
