In glass bottles, you can store dry and wet food cleanly in a cool and dry place to keep it durable. This boiling method for preserving food in glass bottles is probably the most common way to seal mason jars. However, you can also purchase an airtight seal or use an aesthetically pleasing wax sealing method for bottle craft projects. Sealed bottles will keep food for up to a year.
Step
Method 1 of 3: Sealing by Boiling the Bottle
Step 1. Prepare the bottle
Before you start the bottle sealing process by boiling it, prepare the bottle first. First, check for cracks, cracks, or sharp, uneven edges on the bottle or cap. Check the inside and outside of the lid. Make sure the cap fits the bottle. Defective bottles should be set aside. Once you've made sure all bottles are safe to use, wash all bottles and caps with soap in warm water. After washing thoroughly, drain to dry on a rack or dry with a clean cloth.
Step 2. Sterilize the bottle
Place the bottle in a large pot of water. By the time the bottle is inserted, the water should be hot but not boiling. The size of the pot should be large enough for the bottle to be completely submerged in water. Bring the water to a boil. Leave the bottle until it is ready to use.
If you often have to seal glass bottles by boiling, consider buying a bath canner. This is a device specially designed to immerse bottles in water for sterilization. But this tool is just for convenience because if you don't have one you can use a regular large pot
Step 3. Prepare the food to be bottled
When you use the boiling method of sealing, make sure that the food you are bottling contains natural acids or has acid added. This is the only way to ensure bacteria don't multiply in bottled food. While the bottles are sterilized, prepare the ingredients to be bottled.
Foods that are high in acid include fruit, fruit juices, jams, jellies and other fruit jams, salsa, tomatoes with added acid, pickles, relish, chutneys, sauces, vinegar, and seasonings
Step 4. Prepare the stew
First, turn off the stove and remove the sterilized bottle from the pot using tongs. You can also purchase a tool specifically designed to lift bottles out of hot water, namely a bottle clamp. This tool is safer than ordinary clamps. Dry the bottle on a rack or with a clean rag. Then bring the water to a boil in a large saucepan over low heat.
Step 5. Fill the bottle
Set aside boiling water and fill the bottle. Use a funnel to make it easier to get the liquid into the bottle.
- Leave some room for air. For soft ingredients such as jams and jellies, leave about 0.5 cm of air space. For solid foods such as fruit and pickles, leave about 1 cm of air space. Place the bottle cap in place and thread the cap ring tightly.
- Tap the side of the bottle with a wooden spatula to remove the bubbles.
- Repeat this step on the other bottle.
- Do not lock the sealing ring too tightly as the remaining air will not be able to escape.
Step 6. Place the bottle on the steamer rack
This is a tool you can place at the bottom of your bath canner or pot to keep the bottle from touching the bottom and breaking. Make sure you have a steamer rack before starting the sealing process. Never stack bottles on a shelf. Bottle sealing may have to be done in several batches, depending on the size of the steamer rack.
Step 7. Lower the bottle into the boiling water
Place the steamer rack containing the bottles into the boiling water. Process according to recipe directions. Processing time varies depending on the recipe.
- The processing time starts when the water in the pot starts to boil again.
- Make sure the water level is more than 2.5 to 5 cm above the bottle cap. If necessary, add water before bringing it to a boil again.
Step 8. Lift the bottle
Remove the steamer rack containing the bottles and drain them on the counter overnight. Use oven mitts when moving the steamer rack to avoid heat injury. Use tongs or bottle tweezers to carefully lift the bottle off the shelf.
Step 9. Once the bottle has cooled, store it in a cool and dry place
If the cap doesn't look pressed, the bottle isn't sealed. You should eat the contents immediately instead of storing them, or re-seal the bottle with another cap. Before doing so, check for cracks in the bottle.
Method 2 of 3: Sealing with Vacuum Packaging
Step 1. Prepare the necessary items
You need a vacuum packaging machine. You will also need a bottle sealer for vacuum sealing. This is a special device that fits into a glass bottle like a jar, and allows you to vacuum seal it.
Step 2. Sterilize bottles before sealing
As a precaution, sterilize all bottles you will use. You can boil or wash bottles in very hot water in the dishwasher. If it boils, put the bottle in a saucepan and submerge the entire bottle in water. Boiled until boiling. Reduce the heat and let the bottle sit there until you are ready to use it.
Step 3. Fill the bottle
While waiting for the bottles to be sterilized, prepare the food to be preserved. You can make jam or jelly. Many people also store food items that break easily and cannot be stored in airtight bags. For example, small candies or nuts.
- After the food is prepared, remove the bottle from the boiling water. Use tongs or bottle tongs. Dry, then add food.
- Again, leave room for air. For soft foods such as jams or jellies, leave 0.5 cm of air space. For whole foods like nuts or candy, leave 1cm of air space.
- Use a non-metallic spoon to remove air bubbles. To do this, gently press the food with a wooden/plastic spoon around the inner surface of the bottle.
Step 4. Set up the vacuum machine
After the food is ready, prepare the vacuum machine. Put the cap on the bottle to be sealed. Don't put the closing ring on yet. Attach the vacuum machine hose to the bottle sealer. From there, place the device on the bottle. Make sure the appliance is firmly attached so it doesn't fall off when you start vacuuming the bottle.
Step 5. Start the vacuum machine
Do the process according to the instructions of the machine you are using. Usually you just have to start the engine until the engine indicates that the bottle is sealed. You will hear the cap sound “plop” when the bottle is sealed. The machine will also show a green light-like sign indicating that the sealing process is complete.
Step 6. Attach the cap ring to the bottle
Remove the hose from the sealing device. Remove the sealing device from the bottle. After that, attach the ring to the bottle tightly. Store the bottle in a cool and dry place.
Method 3 of 3: Sealing with Night Wax
Step 1. Prepare all the necessary equipment
To seal a bottle with wax, you will need a ceramic wax plate, filament tape, scissors, tea wax, a lighter, and a wax to seal the bottle. You can find these items at craft stores or at department stores. If you can't find it at the nearest store, look it up on the internet. This one sealing process is best suited for glass jars and small neck bottles.
Step 2. Prepare the ceramic night sealing plate on the table
If you bought a night sealing plate with a candle holder underneath, just place the sealer on the table. Otherwise, you will need to place it on a small shelf so that the candles can be placed under it.
Step 3. Light a tea candle
Light a tea candle and place it under a plate.
Step 4. Heat the night
Add any color wax to the top of the ceramic plate. Once the wax has melted, add more wax to the top of the plate until the melted wax has accumulated about 2 cm from the top of the plate.
The night will take about 20 minutes to melt. Turn off the tea candle once this process is complete
Step 5. Pour the alcohol into the bottle
Twist the lid. Make sure the bottle is tightly closed. If this bottle is not going to be filled with food, choose a cork to clog the bottle.
Step 6. Glue the filament tape
Place filament tape around the stopper or bottle cap until it overlaps, i.e. where the stopper/cap meets the bottle. Cut the filament tape. Curl the tape sticking out and seal the ends. This curved part will be used to open the seal later.
Step 7. Dip the bottle
Turn the bottle upside down and dip it directly into the night. Lift it upright after a while. Turn it as soon as the bottle is removed from the wax to prevent unwanted drips.
Step 8. Press the stamp
This step is not mandatory. Press your stamp into the wax on the bottle cap as soon as the bottle is removed. Stamps with monograms or symbols are a great way to personalize your craft projects. Allow the bottle to dry before transferring.
