How to preserve milk and milk products?
Here are some of the heat treatment methods which are used at the dairy farm:
- Thermisation
One of the most common methods to preserve the milk qualities. In this case, the milk is heated for 15 to 20 seconds at a low temperature of %7 to 68 degrees Celsius. In addition, it is growing rapidly at < 6 °C. This method is effective in preventing milk spoilage which can occur due to bacteria. However, this treatment method is not an effective choice for eliminating pathogens. So, this treatment method aims to extend the milk shelf-life and prevent bacteria growth.
- Pasteurization
This method helps preserve food in which the heat is lower than 100° at one point in time. The count of pathogens will be less with time and milk shelf-life is extended. The process of pasteurization can get a number of bacteria like:
- Enterococcus faecium and Enterococcus faecalis
- Bacillus subtilis
- Bacillus cereus
- Lactobacilli.
There are 4 main types of milk pasteurization and with each of them, the time and temperature to heat will vary. It includes:
- Vat pasteurization & Low temperature
- Ultra-Pasteurization
- Ultra-High Temperature
- High Temperature/Short Time
- Sterilization or UHT
Sterilization is a method for preserving food which includes heat application and at one point of time the temperature is 100° and then the bacteria is killed after the packaging comes in air-tight containers/ basically, this mild type can be stored at room temperature for a long period. With this, there are 2 methods which include:
- Conventional method or In-bottle sterilization
- Aseptic method or UHT method
With this method, the milk and milk quality is given importance so that it can be stored at room temperature for a long time.
- Dehydration
With dehydration, the water is removed from the milk through heat application and under controlled conditions through evaporation. The water milk activity is reduced so that milk does not get spoiled. In addition, the nutritive qualities are given utmost importance.
Final Word!
So, if you are running a dairy farm, then it is important to carefully follow the heat treatment method to prevent milk spoilage and give the customers a quality product.
