The pasteurization process will kill the bacteria in the raw juice so you don't get sick. Pasteurization is a fairly simple process. You just heat the juice just below the boiling temperature. Make sure the juice is poured into a clean container to avoid re-contamination. To make the juice last longer, pour it into sterilized jars. Make-Juice
Step
Part 1 of 2: Heating Juice for Pasteurization
Step 1. Pasteurize any raw juice
Raw juices can contain bacteria that can make you sick, especially E. coli bacteria. To avoid this, you should pasteurize any juice labeled "raw". However, if the packaging says "pasteurized", it means that the juice is safe to drink directly.
Step 2. Pour the juice into a large saucepan
Start by preparing a saucepan large enough to hold all of the juice, along with extra space at the top of the pot to contain bubbles as the juice boils. Put the pan on the stove. Pour the juice into the pot.
Step 3. Heat the juice on high heat
Turn on the stove over high heat and heat the juice. Watch the juice as it heats up. Wait until it starts to boil slightly so you can time it and check the temperature. Stir the solution frequently as it heats up.
You can use a double pan. Double pot means that one pan is placed on top of the other and the bottom pan is filled with water. The water in the lower pan will transfer heat to the upper pan, but in a more moderate way than by heating directly from the stove top
Step 4. Check the temperature after the juice starts to boil
Juice must reach 70 °C to be considered pasteurized. Use a candy thermometer to check the juice after it boils, but don't let the thermometer touch the rim of the pot as this could detect the wrong temperature.
- The juice should stay at that temperature for only one minute.
- At the right temperature, the juice should appear to be boiling slightly, but not bubbling. You can tell just by looking at it, but using a thermometer will certainly be more certain.
Part 2 of 2: Cleaning Jars for Juice
Step 1. Wash the jars
You can use a mason jar or any glass jar that can be sterilized by this process. Wash the jars with hot water and soap, then rinse thoroughly to prepare for the sterilization process.
Step 2. Boil the jars
Put the jars in a special boiling container for canning. You can also use a large pot. Fill a pot or container with water and submerge the jar. Heat a saucepan over high heat and let the water come to a boil.
- If you're using a pan, place a shelf underneath to make it easier to remove the jar later.
- If you use tongs, make sure they are also sterilized.
Step 3. Boil the jars for 15 minutes
Once the steam has risen, cover the pot. Simmer for 15 minutes before turning off the stove. Leave the jars in the pan to keep them hot.
The lid of the jar should also be boiled for 5 minutes
Step 4. Use tongs to lift the jar
You can turn the jar over on a clean cloth to let the water drip off. However, given that you're filling it with juice, all you have to do is shake the jar to get most of the water out, then fill it with juice.
Step 5. Pour the juice into the jars
Fill jars with hot juice. The jars must also be hot, otherwise the glass may shatter when filled with juice. Tighten the lid of the jar to maintain pasteurization.
