Microwave Sterilization


Harvesting conservation is a rather laborious process. In addition, a lot of time is not only preparing the blanks, but also preparing the packaging. To speed up this process, many different ways were invented. Some sterilize the jars in the oven, others - in the slow cooker. But the quickest method is to sterilize cans in the microwave. In this article we will talk in detail about how to do it correctly.

Why sterilize jars

Sterilization of cans and lids is a mandatory step in the canning process. Without it, all efforts can go down the drain. It is sterilization that guarantees the safety of the workpieces for a long time. Why it is impossible to just wash the containers thoroughly? Even with very thorough washing it is impossible to get rid of all microorganisms. They can be completely harmless to human health and life. But over time, the waste products of such microorganisms can carry a great danger.

Accumulating in closed cans, they become a real poison for humans. It may be difficult to notice the presence of such bacteria, since, at first, the blank may seem quite suitable for use. Surely everyone has heard such a scary word as botulism. This infection can be fatal. And the source of this toxin is precisely the conservation, which was improperly stored.

Therefore, glass containers for blanks must be sterilized. This is the only way to protect yourself and your family from harmful microorganisms. How to do it correctly and quickly you can read below. In addition, you can see photos of this process, as well as video.

How to sterilize cans in the microwave

First of all, you need to thoroughly wash each jar. Do not skip this step, even if the banks look clean. It is recommended to use the usual soda. Then the containers are dried, leaving upside down on a towel.

Attention! Be sure to check if there is any damage on the banks. Such dishes may burst during sterilization.

It can be difficult to find time for procurement, as it usually takes a lot of time. Housewives have to spend hours preparing vegetables and fruits. So also need to boil each jar. But I really want to prepare as much as possible goodies for the winter. In this case, microwave sterilization is a real salvation.

Besides the fact that sterilization takes a lot of time, it also creates some inconveniences that make the whole process simply unbearable. Initially, all banks are boiled for a long time in water, because of which the kitchen is filled with steam. Then they must be carefully removed from the pan so as not to burn the fingers (which often fails). And it is even more difficult to sterilize the jars above the saucepan with steam.

Previously, many doubted that the sterilization of blanks in the microwave is safe. But over time, they became convinced of the practicality and harmlessness of this method. The main thing is not to put containers with lids in the microwave.

Sterilization of cans in a microwave oven is carried out in several ways:

  • without water;
  • with water;
  • immediately with the workpiece.

Sterilization of water cans

Most often, housewives sterilize jars in the microwave with the addition of water, thus, the same effect is obtained as after sterilization over steam. It happens as follows:

  1. Banks first wash with the addition of soda and pour a small amount of water into them. The liquid should fill the jar by 2-3 cm. For these purposes, it is better to take filtered water, as ordinary water from the tap can leave a raid.
  2. Now containers can be put in the microwave. Do not cover the jars with lids.
  3. We put the microwave at maximum power.
  4. How many tanks need to be sterilized? Set the timer to 2 or 3 minutes, depending on the size of the jar. Usually this method sterilized half-liter and liter containers. However, there are ovens in which you can easily fit a three-liter jar. In this case, sterilization will take longer than at least 5 minutes. Since microwaves can be of different power, it may take more or less time. In order not to be mistaken, you need to monitor the water. After it boils the jars are left in the oven for another couple of minutes and turn off.
  5. To get the container from the microwave, use special oven gloves or a dry kitchen towel. The main thing that the fabric was not wet. Because of this, there will be a sharp jump in temperature and the bank may just burst. In order not to risk, reach for the container with two hands, and not at the neck.
  6. If there is water left in the jar, it must be poured out, after which the container is immediately filled with the blank. While you roll one jar, the rest can be put on a towel upside down. Each subsequent can is turned over just before filling it with the finished product. Therefore, the temperature will not fall so fast.
Important! Remember that hot jars can be filled only with hot contents, and cold ones, respectively, with cold ones.

Usually about 5 half-liter jars are placed in the microwave. If you need a larger container, for example, a three-liter jar, you can lay it on its side. In this case, be sure to put a cotton towel under it and pour some water into the container.

Sterilization without water

If you need completely dry containers, you can use the following method. Banks must be washed and dried on a towel. After they are completely dry, place the containers in the oven. Next to them you must put a glass of water (filled to 2/3). If you pour a full glass of liquid, then in the process of boiling it will pour out over the edges.

Next, turn on the microwave and wait until the water is completely boiled away. Usually it takes 5 minutes. Then the banks are taken out of the microwave, as in the previous method. Hot containers are immediately filled with jam or salad.

The advantages of this method

Although this method has some drawbacks, advantages prevail. No wonder it has long been used by many hostesses. The main advantages include the following:

  1. It is fast and very convenient compared to the classical sterilization method.
  2. Several cans are placed in the microwave at once, due to which the preservation process is faster.
  3. Microwave does not increase the humidity and temperature in the room.
Attention! In addition to containers for blanks, in the microwave can sterilize bottles for children.

You just need to put the bottle in a disassembled form in any bowl of water. Then turn on the microwave and wait about 7 minutes.


Experienced housewives have long used oven-microwave to sterilize cans with blanks. To do this is very simple, and, most importantly, quickly. Sure, the methods described above will facilitate your work, and you will be able to prepare even more conservation for the winter.
