The milk you buy in the store is almost always pasteurized. that basically means it was disinfected so you can drink it without any bacteria or harmful organisms that might possibly be in it. This instructable shows how to pasteurize milk at home.
Step 1: Needed Stuffs
for this you will need
- glass milk bottles
- raw milk
- double boiler
- metal-stem thermometer
Step 2: Preparations
Boil empty milk bottles submerged in water for 10 minutes to disinfect them. Alternatively, you can place the milk bottles in an oven preheated to 212 degrees F (100 degrees C) for 20 minutes to disinfect.
Step 3: More Preparations
Pour raw milk into the top of a double boiler and fill the bottom section with water. Place a metal-stem thermometer into the milk to monitor its temperature. Keep the thermometer from touching the sides or bottom of the double boiler so you get an accurate temperature reading of the milk, not the container.
Step 4: The Pasteurization
Heat raw milk to 145 degrees F and keep it at that temperature for at least 30 minutes. Stir constantly to avoid burning and to maintain an even temperature. For a faster method, heat the milk to 165 degrees F for at least 15 seconds, stirring constantly.
Step 5: Cooling and Storing the Milk
Put the top section of the double boiler that holds the heated milk into a pan of cold or ice water to cool the milk. Continue to stir. Cool the milk until it reaches 40 degrees F or below. Pour the pasteurized milk into the disinfected milk bottles. Cover and store in the refrigerator.
Step 6: Unnamed Step
the whole process only takes about 30-45 min. at the most. after that enjoy!
note: I got all the pictures of the internet because my camera is broken at the time.
You can keep pasteurized milk stored in the refrigerator for up to two weeks.
If you have read this Instructable, and attempted to pasteurize your own milk I am not responsible for anything that happened during the process of pasteurizing milk by these guidelines including burns, bruises, illnesses, etc. I am not responsible for anything but creating this instructable to inform you on how to pasteurize milk. Do your best.
Step 7: Information on Milk
goats milk is the most popular type of milk worldwide.
pasteurization and homogenization are very different.
homogenization is when the milk is pumped through a small orifice (opening) like that of a can of spray paint. This causes the milk fat to be torn into molecules so small they cannot glob together again. this makes shaking your milk obsolete.
