CARA PEMBUATAN SUSU PASTEURISASI - HOW TO MAKE PASTEURIZED MILK?

Summary

This instructional video from Group 5 AP2 demonstrates how to make pasteurized milk. It explains the pasteurization process, where fresh milk is heated to 65°C for 30 minutes to eliminate bacteria and extend shelf life. The tutorial covers steps such as sanitizing equipment, adding sugar and flavors, homogenizing the milk, and maintaining the proper temperature. The video also emphasizes the importance of hygiene and careful temperature control to achieve the best results. The group encourages viewers to try making pasteurized milk at home and store it safely in the fridge.

Takeaways

• 😀 Pasteurized milk is fresh cow's milk that has been heated to 65°C for 30 minutes to kill bacteria and extend shelf life.
• 😀 The purpose of pasteurization is to kill harmful bacteria and deactivate enzymes that could spoil food.
• 😀 The process involves heating the milk carefully to a consistent temperature to avoid contamination and maintain quality.
• 😀 Ensure all equipment used for pasteurization, especially metal tools, is properly sanitized to prevent bacteria contamination.
• 😀 Key ingredients for pasteurization include fresh milk, sugar, flavoring, and a thermometer for precise temperature control.
• 😀 The milk should be heated in a small pot and placed in a larger pot of boiling water to control the temperature.
• 😀 Stir the milk consistently in one direction to prevent cream from forming and to achieve even homogenization.
• 😀 Use a thermometer to ensure the milk stays at 65°C for 30 minutes. Adjust the heat to maintain a stable temperature.
• 😀 After 30 minutes, remove the milk from the heat source and pour it into a glass for serving while still warm.
• 😀 Pasteurized milk can be stored in the refrigerator to maintain its quality and freshness for longer periods.
• 😀 The entire process is easy to follow, and with the right tools and attention to temperature, anyone can make their own pasteurized milk.

Q & A

What is pasteurized milk?

Pasteurized milk is fresh cow's milk that has undergone a heating process at 65°C for 30 minutes. The purpose is to kill bacteria and prolong the shelf life of the milk by deactivating bacteria and enzymes, particularly in acidic food.

What is the main purpose of pasteurizing milk?

The main purpose of pasteurizing milk is to kill harmful bacteria and deactivate enzymes, which helps extend the milk's shelf life and improve its safety for consumption.

What are the steps to sanitize equipment for pasteurization?

First, you need to sanitize the equipment that will be used in the pasteurization process, ensuring that all tools, particularly metal ones, are clean and free from contaminants.

What ingredients and tools are needed to make pasteurized milk?

You will need the following: a stirring spoon, 1 liter of fresh milk, optional food coloring or flavorings, 4 tablespoons of sugar, a thermometer, a small glass, and two pots—one small and one medium-sized.

How do you prepare the pots before starting the pasteurization process?

First, heat water in the medium-sized pot until it begins to simmer. Then, place the small pot containing the fresh milk into the simmering water to begin the heating process.

What is the role of homogenization during the pasteurization process?

Homogenization is used to reduce the clumping of fat in the milk and prevent the formation of cream. It ensures the milk remains smooth and evenly mixed.

How do you maintain the temperature of the milk during pasteurization?

You need to monitor the temperature of the milk carefully using a thermometer, ensuring it stays at 65°C for the entire 30-minute period. Adjust the heat of the stove if necessary to maintain the correct temperature.

How long should the milk be heated during pasteurization?

The milk should be heated for 30 minutes at 65°C to ensure proper pasteurization and bacteria deactivation.

What should be done after 30 minutes of heating the milk?

After 30 minutes, turn off the stove and carefully remove the small pot containing the pasteurized milk. Pour the milk into a glass for consumption.

How should pasteurized milk be stored to maintain its quality?

Pasteurized milk should be stored in the refrigerator to preserve its quality and extend its shelf life.
