Sterilization of glass jars by boiling. How to sterilize glass jars
Sterilization is the removal of all types of microorganisms and fungal spores from objects. This procedure must be approached responsibly, otherwise winter preparations and any other products will deteriorate and become hazardous to health.
When sterilizing by any method, in order to get an excellent result, it is necessary to adhere to the general principles:
- Integrity. In other words, the dishes should not have cracks or chips, otherwise it will be dangerous to store food in it. Damaged containers must be disposed of.
- Sterilized containers should be taken with clean, dry potholders or a towel. The container is hot after sterilization, so you can just burn your hands.
- After sterilization, place the cans on dry, clean cloth with the neck down so that harmful microorganisms do not get into them as they cool. Turn the container over immediately before filling.
- The containers should be filled with a workpiece whose temperature is close to the temperature of the container. Otherwise, the glass will crack, and you will ruin your products, and you can also cut your hands.
- The bank should always be taken with both hands on the sides so that it does not slip out and break.
Sterilization in boiling water
This is one of the common ways to sterilize glassware at home. You need to take a wide pan, fill it with water less than half the volume, and immerse there the cans filled with water.
After that, it is necessary to bring the water to a boil on the stove. Usually sterilized in a pot pan, up to one liter. The operation time is 10-15 minutes from the moment of boiling water.
In the oven
The next method, which is widely used by experienced housewives, is to sterilize glassware in the oven. The difference of this method is that the use of water and steam is excluded. This is a dry sterilization.
It is necessary to put the cans in a cold or slightly preheated oven. If the containers are dry, then they are installed upside down. Jars with leftover water should be placed upside down to evaporate it. You can install several cans of different volumes at once. Place containers on a wire rack or on a baking sheet. The oven must be heated to 150 degrees. Sterilization time, depending on the volume of the container, is 10-30 minutes.
Ferry
A decades-old method of preparing containers is to sterilize them over water vapor. This method was also used by our grandmothers. You must take a pot or kettle.
You will also need a special stand, which can be purchased at a hardware store. The stand has a recess for one or more cans, depending on the width of the pan. For lack of supports, you can also use a simple double boiler or net, which protects against splashing oil during frying.
If you are using a regular (non-electric) kettle, a stand is not required. It is necessary to pour water into the kettle and instead of the lid set the jar upside down.
The time for processing dishes from the moment of boiling water depends on the volume of the container and ranges from ten minutes to half an hour.
In the microwave
The most modern tool for preparing cans for canning is a microwave oven. This method has many advantages. The most important of them is high speed. Moreover, in the room in which the processing is carried out, there is no steam.
To process the dishes in the microwave, it is necessary to pour a little clean water into it (up to two centimeters from the bottom). Do not place empty containers in a microwave oven. Sterilization is carried out at maximum power for 1-8 minutes. During this time, the water will boil, and the microbes on the surface of the dishes will be destroyed by the steam.
The number of dishes placed depends on the volume of the microwave. Two-, three-liter cans, if they do not fit, can be put on their side. At the same time, it is necessary to pour so much water into the jar so that it does not pour out.
Important! Miss Purity magazine recalls that sterilizing iron covers in this way is absolutely impossible.
In the dishwasher
This is the simplest and most effective method, but not all homes have a similar device.
Banks are placed on two sliding shelves of the dishwasher. Then the machine must be set to heating up to the highest temperature and turned on.
Advice! Dishwashers are much more spacious than microwaves and ovens. However, it is often impossible to establish water heating above 80 degrees, or even less. Therefore, there are some doubts about the quality of sterilization by this method.
You can prepare food for preservation while the dishwasher sterilizes glass containers. The longer this process lasts, the better.
Cold way
A known method of processing containers for canning with alcohol. Can I find other similar cold sterilization products in my home environment? It is recommended to use vinegar.
It is necessary to take a half-liter jar, pour cold boiled water into it to the shoulders. Then add 7 tablespoons of 70 percent vinegar. Get a sterilizing solution.
The container, as usual, must be thoroughly washed, then pour the resulting solution into it, close the lid and shake well for twenty seconds. After this, the solution must be poured into the next jar and repeat the process.
After sterilizing the container, it is necessary to hold it upside down for some time so that the glass liquid from the walls. The prepared solution is enough to handle fifty cans.
This requires a wide pan, on the bottom of which is a clean towel or any fabric. Then you need to arrange the cans filled with products and covered with lids so that they do not touch each other. After that, carefully pour cool or slightly warm water into the pan, so that the water does not reach the covers about two centimeters. Then bring it to a boil.
Advice! During pasteurization, you can not put the cans on the bottom of the pot with boiling water. Due to the temperature difference, the glass may crack.
Processing time depends on the volume of cans and is approximately 10-15 minutes. Can be sterilized longer.
Then the containers with the contents must be carefully removed from the water using a special device that is commercially available, and rolled up with a machine.
When the cans are sterilized, filled and rolled up, they must be turned over and put on the lids. Hot canned food is recommended to be placed on a wooden surface. To slow down the cooling process, the cans should be wrapped in a warm blanket or outerwear. When the workpieces have cooled down, they can be removed for permanent storage.
So that the work was done not in vain and the prepared products did not deteriorate, it is necessary to thoroughly process the lids.
They also must first be washed with a sponge with soap, soda or shampoo for dishes. After this, the lids are placed in a container of boiling water and held for two minutes.
The lids used for rolling canned food must be in perfect condition. On their surface should not be present traces of rust, scuffs and dents. Elastic bands should be selected according to diameter of a cover.
These are the most famous simple sterilization methods. Use them on the farm. Choose the method that is most convenient for you.
Sterilization of cans is an important stage in the conservation of products. Only high-quality and properly prepared containers will ensure the safety and good taste of the workpieces. There are several ways to sterilize containers: steam, in the microwave, in the oven. The main thing is to observe all the nuances and subtleties of the process. There are methods that allow you to carry out the procedure with the container already filled. How to sterilize cans for preservation?
Training
Before sterilization, prepare containers. Inspect the cans for chips and cracks. If there is the slightest damage, do not use such a container: it may burst during filling or pouring boiling water.
Wash cans thoroughly. Detergent for dishes in this case will not work. If heavily soiled, use soda or mustard powder and the hard side of the sponge. After washing, rinse the container well and place it on the towel with the neck down, so that the glass is excess liquid.
For a couple
This is the oldest and most effective way that is actively used by housewives in recent decades. This method, despite its simplicity, requires a certain sequence of actions.
First of all, prepare a large saucepan (this will not monitor the amount of liquid during processing). Fill the container halfway with water and place it on the stove. Wait for boiling and place a special lattice or stand on the pan. Place the cans upside down so that the steam enters them.
The duration of sterilization depends on the volume of the container. So, it is enough to process half-liter and liter cans for 4–7 minutes, and three-liter cans should be kept steamed for at least 12–15 minutes. After the procedure, the walls of the jars should be completely transparent, clean and dry. If there are stains or drips on the surface, then most likely you did something wrong.
Immediately after sterilization, fill the containers with blanks, fill with water and close the lid, which should also be treated by holding it for a couple of minutes in boiling water. If several cans are steamed at once and there is no way to fill them at the same time, place them with the neck down on a dry clean towel and turn them over immediately before filling.
In the oven
Using the oven you can process containers of different sizes at the same time, which significantly saves time. In addition, this method allows you to sterilize metal caps. However, it is worth pre-stretching the rubber inserts - they deteriorate under the influence of high temperatures.
To sterilize cans in the oven, place clean, dry containers on the wire rack upside down. Close the door and turn on the oven at +150 ⁰С. The processing time depends on the volume of the container and its quantity, but on average is 10–25 minutes.
In the microwave
The modern method of sterilization involves the use of a microwave. The main advantage is the lack of steam in the kitchen and the ability to process several containers at a time.
For sterilization, follow simple steps: pour a little water (2 cm from the bottom) into clean jars, put the container (if only one big one is placed, lay it on its side), select the mode with a power of 700–800 W and turn on the microwave. The processing time depends on the number of containers and its size. It takes 2 minutes to sterilize one small container, and it takes 4-5 minutes to process one 3-liter jar or several small ones.
Boiling
A fairly simple and effective method of sterilization is boiling. Fill cans in large dishes and pour water so that they are completely covered. To avoid contact and possible bumps, transfer containers with gauze or thin towels. Bring the liquid to a boil and maintain this regimen for 15 minutes.
Sterilization with blanks
In the microwave, sterilized cans can already be sterilized. This method is suitable for preserving whole fruits. Fill the container with vegetables and half fill with brine. Close the capron lid and put in the microwave for 2-3 minutes. Then take out the cans, top up with boiling brine and roll up with metal lids.
Sterilization of filled cans is suitable for preserving vegetables.
Correctly sterilize jars with blanks by boiling. To do this, prepare a large container (pot or basin), cover the bottom with a towel and pour a little water. Put jars filled with vegetables or berries. Make sure that the temperature of the water in the basin and containers with preservation is approximately the same, otherwise a sharp drop can cause the glass to burst. Bring the liquid to a boil and sterilize for the period indicated in the recipe.
Processing can be done in the oven. To do this, warm it up a little, place containers with blanks with the neck up on the grill and bring the temperature to +120 ⁰С. Sterilize the jars for 10–20 minutes, and then close the lids.
Other methods
There are other, less well-known, but equally effective methods for properly sterilizing cans at home.
- Wash containers well with soap and water and then vinegar. Then wash them in clean water and put to dry upside down on a clean towel. You can start filling only after the container is completely dry.
- You can sterilize jars in the sun. This is the easiest and most economical method. Place clean containers on the windowsill so that they get maximum sunlight. Leave them for a few hours, and then proceed with conservation. Ultraviolet rays kill most bacteria and germs that can be on the walls of cans.
- If you have a double boiler, use it. Place the washed can on a special grate above the steam and hold it for 10-15 minutes.
- Sterilize cans in the dishwasher. Fold the container and start the device by choosing the maximum temperature regime. Do not add any detergents. After the end of the program, remove the prepared jars and fill them with vegetables or fruits.
