Sterilized milk is a type of milk that has been subjected to a high-temperature treatment to kill all bacteria present in the milk, including spores, which can be resistant to lower-temperature treatments such as pasteurization. The high-temperature treatment is usually conducted at a temperature of around 115-130°C for at least 30 minutes.
The sterilization process is designed to destroy all microorganisms present in the milk, including both harmful and beneficial bacteria, which means that sterilized milk has a longer shelf life than pasteurized or raw milk. Sterilized milk can be stored for several months without refrigeration, as long as the package remains unopened.
However, sterilization can also affect the taste and nutritional value of the milk, as the high temperature can cause the milk to develop a slightly caramelized or cooked taste and can also break down some of the nutrients in the milk. For this reason, sterilized milk is less popular than pasteurized or raw milk in many countries, although it is still commonly consumed in some regions of the world.
The market scope for sterilized milk is somewhat limited compared to other types of milk, such as pasteurized or UHT (Ultra High Temperature) treated milk. This is because sterilized milk has some disadvantages, such as the impact on taste and nutritional value, which can make it less popular among consumers.
However, sterilized milk is still consumed in many parts of the world, particularly in regions where refrigeration is not widely available or reliable, or where milk supplies are limited. Sterilized milk can be stored at room temperature for several months without spoiling, which makes it a convenient option for consumers in these regions.
Sterilized milk is also used in some food manufacturing processes, particularly in the production of baked goods, desserts, and other products that require a long shelf life.
The market scope for sterilized milk is expected to remain relatively stable in the coming years, with some growth potential in developing regions where there is a demand for long-lasting milk products. However, the market for sterilized milk is likely to remain somewhat niche compared to other types of milk that are more popular among consumers.
Here are some of the major players in the global market for sterilized milk:
- Parmalat
- Candia
- Dairy Farmers of America
- Friesl and Campina
- Almarai:
- Nestle
The commercial production of sterilized milk involves subjecting raw milk to a high-temperature treatment to kill all microorganisms present in the milk, including spores that can be resistant to lower-temperature treatments such as pasteurization. The process typically involves the following steps:
- Raw milk is first preheated to around 80-85°C to remove any air bubbles and improve the effectiveness of the sterilization process.
- The preheated milk is then pumped into a sterilization vessel, which is sealed and pressurized with steam.
- The milk is then subjected to a high-temperature treatment, typically around 115-130°C for at least 30 minutes, to kill all microorganisms present in the milk.
- After sterilization, the milk is cooled rapidly using a heat exchanger and then packaged in sterile containers, such as bottles or cans, which are sealed to prevent contamination.
The high-temperature treatment used in sterilization can have some drawbacks, such as the impact on taste and nutritional value, which can make the milk less popular among consumers in some regions. However, sterilized milk has a longer shelf life than pasteurized or raw milk, which makes it a convenient option for consumers in regions where refrigeration is not widely available or reliable.
Commercial production of sterilized milk is typically carried out by large dairy companies, which have the equipment and expertise required to ensure that the sterilization process is carried out effectively and safely. In addition to being sold as a standalone product, sterilized milk can also be used as an ingredient in a wide range of food products, such as baked goods, desserts, and other products that require a long shelf life.
