Love making your own jams and chutneys? Check out our step-by-step guide that teaches you how to store your homemade jams in a hygienic way.
Fruit jams and preserves should be placed in sterilized glass jars and sealed while still hot. Your glass canning jars must be free of chips or cracks. They need to be sterilized and dried with clean hands before use. Hygiene is important, so use a clean tea towel when holding or moving the glass jars.
Tips:
1. Before you start sterilizing the glass jam jars, remember to remove the lids and rubber seals so they don't get deformed by the heat.
2. In every method of sterilizing glass jars, pay special attention to the heat so as not to burn yourself.
The way to sterilize jars
1. Sterilize fruit jam jars in the dishwasher
The easiest way to sanitize jam jars is to put them in the dishwasher.
1) Place your jars on the top shelf of the dishwasher.
2) Turn on the dishwasher with hot water without detergent.
3) Once the cycle is over, your jar is ready to be filled - so try to schedule your recipes to fit into the package.
2. Sterilizing jars in ovens
If you don't have a dishwasher on hand and you still don't know how to sterilize jam jars, try the oven.
1) Wash the jars with hot soapy water and rinse.
2) Next, place them on a baking sheet and put them in a preheated oven at 140-180°C.
3) Fill the jar immediately, being careful not to get burned by the hot glass.
3. Sterilizing glass jars in a water bath
1) Remove the lid and seal as before, and place the jars in a large pot.
2) Place the pan on a hob and slowly raise the temperature until it comes to a boil.
3) Never place jars in water that is already boiling, as this can cause them to explode and spray dangerous shattered glass in all directions.
4) Keep the water boiling for up to 10 minutes, then turn off the heat and cover the pot with a lid.
5) The jars can stay in the water until you are ready to fill them.
4. Sterilize glass jam jars in the microwave
While the methods used above are very effective, they can be time-consuming (although this shouldn't be a hindrance to sanitation). If you're looking for a faster method, sterilizing jam jars in the microwave is a quick and easy way to do this.
1) Wash the jar with soapy water.
2) Place the jar in the microwave and turn it on "high" (about 1000 watts) for 30-45 seconds.
3) Pour onto a dish towel or absorbent kitchen paper to dry.
And now you have an easy-to-follow guide that teaches you how to sterilize glass jars to make hygienic and safe fruit jams!
5. Steam Sterilization Method
1) Fill the steamer with water and heat until steam is generated.
2) Place glass food jars, open side down, in the steamer, being careful not to let the jars touch the bottom of the pot.
3) Cover the pot and allow the jars to sterilize in the hot steam for 10-15 minutes.
4) When sterilization is complete, turn off the power and remove the jars when the steamer has cooled.
6. UV Sterilization
1) Purchase UV sanitizing lamps designed for food contact surfaces.
2) Place glass food jars within the effective range of the UV lamp.
3)Turn on the UV lamp to sanitize according to product instructions. Irradiation is usually required for 30 minutes or more.
4) When using the UV lamp, ensure no one is exposed to the light to prevent human harm.
Why sterilize jam glass jars?
The importance of sterilizing jam jars should not be overlooked; it is a matter of safety and hygiene, as well as the long-term preservation of jam. Firstly, sterilizing jars effectively kills microorganisms that may be present in the jars, which are the main factors contributing to the deterioration of jams. Sterilization, which destroys enzymes contained in the jam and microorganisms in the can that can spoil the jam, ensures that the food remains fresh and safe during storage.
Secondly, the sterilization process helps to achieve a commercially aseptic condition, which means that the contents of the food cans have been rigorously processed to be free of any viable bacteria and can be stored for long periods without deterioration. This status is especially important for canned foods, which typically need to be stored at room temperature for longer periods.
Sterilization of jam glass jars is important in ensuring food safety and prolonging shelf life. We should pay attention to the disinfection work, choose the appropriate disinfection method, and ensure that the disinfection process is standardized and effective.
Tips for sterilizing glass jam jars
Please ensure that the jam glass jar is dry and undamaged before performing any sterilization operation.
Different sanitizing methods may apply to lids made of different materials, so please choose the appropriate method according to the actual situation.
Be sure to dry or wipe the jars thoroughly after sterilization to prevent bacterial growth.
How to seal glass jam jars?
1) Make sure that the jam jars, lids, and seals are clean. If you are using old lids, it is recommended that you carefully wipe the inside of the lids and gaskets with a cotton cloth soaked in 90-degree alcohol.
2) Fill the jars with jam while it is still hot, making sure that the jars are full, but not overfilled so that the jam has room to shrink as it cools.
3) Ensure that the lids are screwed on tightly, you can use a rag or gloves to increase friction and ensure a tight seal.
4) Invert the sealed jars for a few minutes to use the weight of the jam to press down on the lids and help create a vacuum for a better seal.
