What is the effect of freezing on bacteria?
Bacteria like Archaebacteria can survive in extreme temperatures but eubacteria cannot. Since Eubacteria die from the harsh temperature and Archaebacteria cannot reproduce your immune system kills all of the Archaebacteria. That is why freezing in a technical sense stops bacteria from reproducing.
At what temperature will bacteria lay dormant on food in a freezer?
Food poisoning bacteria go dormant at and below freezing. All bacteria are dormant below -17ºC or 1.5ºF
Will Refrigerating or freezing foods will kill any bacteria present in the food?
Refrigerating and freezing can slow down the growth of bacteria, but they will not necessarily kill all bacteria present in the food. It's important to follow proper food safety practices, such as cooking foods to the appropriate temperature, to ensure that harmful bacteria are destroyed.
Are bacteria killed by freezing?
Freezing can slow down the growth of bacteria but may not always kill them. Some bacteria can survive freezing temperatures and become active again when thawed. To effectively kill bacteria, it is recommended to either use high heat (e.g. cooking) or certain chemicals (e.g. sanitizers).
How does freezing food preserve food?
it prevents it from inadequate preparation and cooking. so that the food can last for a long time.

Which o the following slow the growth of germs?
Keeping food refrigerated helps to slow down the growth of bacteria. Freezing food thoroughly is more certain to prevent bacteria from multiplying.

If a food spoiled and then was placed in the freezer would it kill bacteria?
Freezing doesn't necessarily kill bacteria. It stops them from multiplying, but they can revive when the food is thawed. And the toxins they produced before being frozen will still be there.
What temperature does bacteria thrive in food tech?
Any temperature less than around 60 °C for most bacteria. However, there are bacteria in food that can survive past 100 °C. Freezing does not significantly kill bacteria, but puts it into a dormant stage, where they can no longer thrive and reproduce.
What are the method of preserving food?
Drying, Salting, Pickling, Fermenting, Smoking, Freezing, Cooling, Sugaring... Most methods involve taking water out of the food or inducing a concentration gradient to kill bacteria (by sucking water out of it). Others involve coating the food with some chemical that kills bacteria but is (relatively) safe for humans to consume.
Does freezing yogurt kill the bacteria present in it?
Freezing yogurt does not kill all the bacteria present in it, but it can reduce the overall number of live bacteria. Some bacteria may survive the freezing process, but the cold temperatures can affect their viability and activity.
What is a food safety benefit to freezing food?
Freezing food can help prevent the growth of harmful bacteria that cause foodborne illnesses. It can also slow down the enzymatic and chemical reactions that lead to food spoilage, extending the shelf life of food.
Why does food go mouldy?
All food has bacteria and little spores of fungi on it. Over time the bacteria and fungi grows but can be slowed by freezing and refrigeration. Though that is the case, they still grow and will eventually spoil.If you keep defrosting and freezing the same batch of food that is growing a bacteria colony right there. Same as reheating and refrigerating the same batch of food.
