New plastic honey jars don't need sterilising

New plastic honey jars do not need to be sterilised. They are manufactured and packaged for immediate use, and the manufacturing process ensures they are as pure as they can be. However, it is important to ensure that the jars are completely dry before filling them with honey, as any moisture can cause the honey to ferment. Exposing the jars to the air for too long can also increase the risk of contamination by airborne yeasts and bacteria.

Some beekeepers choose to sterilise their honey jars, particularly if they are not new. This is done to remove any contamination from storage or transportation, such as rodent or human urine, which could infect people or animals. Sterilisation can also prevent the transfer of familial bacteria, which can cause illness in people who are not immune.

There are several methods for sterilising honey jars. One common method is to use a dishwasher on a hot wash. Another is to place the jars in an oven preheated to 140-150 degrees Celsius, which is then switched off to allow the jars to cool. A third method is to submerge the jars in a large saucepan of water, bring it to a simmer, and simmer for 20 minutes before allowing the jars to cool in the pan.

It is important to note that heat can deform plastic honey jars, so it is recommended to avoid boiling plastic jars or exposing them to high temperatures. Instead, new plastic honey jars can be rinsed with warm water and allowed to air-dry upside down. This will ensure that they are free of any dust, hair, or other contaminants that may have come into contact with the jars during storage or transportation.

Overall, while sterilisation may be a good practice for some beekeepers, it is not necessary for new plastic honey jars that are manufactured and packaged for immediate use. Proper cleaning and drying techniques can ensure that the jars are safe and ready for filling with honey.

Rinse with warm water and air-dry

When sterilizing plastic honey jars, it is important to ensure that they are completely dry before use, as honey will ferment if it comes into contact with moisture. To avoid this, rinse your plastic honey jars with warm water and allow them to air-dry.

Firstly, fill a sink or large bowl with warm water. You can add a mild detergent to the water, such as anti-bacterial dish soap, or a small amount of bleach. Ensure that you are wearing gloves if using bleach. Submerge the jars in the water and use a bottle brush to thoroughly scrub the inside of the jars. Pay particular attention to the threads for the cap, as this area can be difficult to clean. If you are sterilizing multiple jars, you may need to refresh the water to ensure it stays warm and clean.

After scrubbing the jars, remove them from the water and empty the sink or bowl. Refill with clean, warm water and submerge the jars again to rinse off any soap or bleach residue. Alternatively, you can use distilled water for the final rinse, which will ensure that all soap residue is removed.

Once the jars have been thoroughly rinsed, remove them from the water and place them upside down on a clean, dry surface. Allow the jars to air-dry completely before filling them with honey. This may take some time, so plan ahead to ensure you have enough jars ready for use.

It is important to note that plastic honey jars should not be boiled or placed in the dishwasher, as the heat can deform the plastic. Additionally, avoid using abrasive cleaners or scouring pads, as these can damage the plastic. By following these steps and allowing the jars to air-dry thoroughly, you can ensure your plastic honey jars are clean and ready for use.

Avoid dishwashers and hot water

While dishwashers and hot water are commonly used to sterilise glass jars, they are not suitable for plastic honey jars. This is because plastic bottles are formed by heating them to several hundred degrees and then blowing air into them to shape them into a mould. When plastic is heated above 130 degrees, it will try to return to its original shape. Therefore, dishwashers are a "definite no-no" for plastic bottles.

Honey customers have reported that they have put plastic honey bottles in hot water to reliquify the honey, only for the bottle to distort. This is because heat of any kind will deform the thermoplastic.

New jars, straight out of the box, do not need to be sterilised. They are as clean as they will ever be due to the manufacturing process. However, they must be absolutely dry before filling with honey, or the honey will ferment.

If you are using second-hand jars or have any concerns about the cleanliness of your jars, you can wash them in hot, soapy water, rinse them thoroughly, and dry them completely before filling them with honey.

Sterilise in the oven at 140-150°C

When sterilising plastic honey jars, it is important to note that plastic containers are not always suitable for sterilisation methods that involve heat. This is because some plastics have a low melting point and will deform when exposed to high temperatures. Therefore, it is crucial to ensure that the plastic jars you intend to sterilise can withstand the heat. Always use personal protective equipment when working with high heat.

To sterilise plastic honey jars in an oven at 140-150°C, follow these steps:

  • Check the plastic jars for any contamination or improper storage that may have occurred. If the jars have been stored in intact plastic bags inside a box, they may not require sterilisation as they are usually clean due to the manufacturing process.
  • If the jars need sterilisation, preheat your oven to 140-150°C.
  • Place the plastic honey jars upside down on a baking tray or directly on the oven racks if they are stable enough.
  • Leave the jars in the oven for an appropriate amount of time. The duration may vary depending on the level of sterilisation required and the specific oven settings.
  • After the allotted time, turn off the oven but keep the oven door closed. Allow the oven and the jars to cool down gradually to a manageable temperature.
  • Once cooled, remove the jars from the oven carefully, as they may still be relatively hot.
  • Ensure the jars are completely dry before filling them with honey. Any moisture left in the jars may cause the honey to ferment due to exposure to airborne yeasts and bacteria.

It is important to note that oven sterilisation may not be the best method for plastic honey jars due to the risk of deformation. Alternative methods, such as using a dishwasher or rinsing with warm water, may be more suitable for plastic containers. Additionally, honey has natural antibacterial properties, further reducing the need for rigorous sterilisation.

Boil glass jars, but not plastic

When sterilising plastic honey jars, it is important to note that they do not need to be sterilised if they are new. The manufacturing process ensures that they are clean and ready for use. However, if you do wish to sterilise plastic honey jars, avoid using heat of any kind as this will deform the thermoplastic. Instead, rinse the jars in warm water and allow them to air-dry.

Glass jars, on the other hand, can be sterilised by boiling. To do this, place the glass jars in a water processing vessel and bring the water to a boil. Use an appropriate tool, such as tongs, to remove the jars from the boiling water, being careful not to burn yourself. It is important to ensure that the glass is not cold when you pour boiling water into it, as this can cause the glass to crack or break due to the temperature shock. Instead, preheat the oven to a temperature of around 140 degrees Celsius, place the jars inside, and then switch off the oven. Allow the jars to cool inside the oven to avoid thermal shock. Alternatively, you can run the jars under hot water before pouring boiling water into them.

Another method for sterilising glass jars is to place them in the dishwasher. This method is also suitable for plastic jars. Ensure that the jars are dry before filling them with honey, as moisture can cause the honey to ferment.

It is worth noting that some people choose not to sterilise their jars at all, especially if they are new and have been stored properly. Honey is a natural antibacterial substance, so contamination is less of a concern.
