why do you turn jars upside down when canning?
Capping jars upside down helps to ensure a proper seal by creating a vacuum. The heat from the canning process causes the air inside the jar to expand and escape, creating a negative pressure inside the jar. As the jar cools, the air outside the jar contracts, creating a vacuum that draws the lid down tightly against the jar, forming a seal. Additionally, turning the jars upside down helps to prevent food particles from getting trapped in the lid, which can interfere with the sealing process. Furthermore, turning the jars upside down helps to distribute the heat evenly throughout the jar, ensuring that all of the food is properly processed. Finally, turning the jars upside down helps to prevent the jars from breaking, as the pressure from the vacuum is more evenly distributed.
what is a false seal in canning?
False seal is a canning term that refers to an imperfect seal on a can, which can allow air or microorganisms to enter, leading to potential spoilage or contamination of the product inside. It occurs when the lid of the can is not properly sealed to the body of the can, resulting in a gap or opening. This can happen due to various reasons, such as a faulty seaming machine, improper can preparation, or damage during handling or storage. A false seal can also occur if the can is not filled to the appropriate level, leaving a headspace that allows for movement and potential leakage. It is important to detect false seals during the canning process to ensure the safety and quality of the product. This can be done through visual inspection, vacuum testing, or other quality control measures. If a false seal is detected, the affected cans should be removed from the production line and discarded to prevent contamination of other products.
