What enzymes are in jam?
None, the canning temperatures denature and destroy any enzymes that were in the fruits.
Why does canning employ temperatures above 100 degree Celsius to destroy bacteria What temperature Is used?
It is necessary to bring homemade canned goods to a boil (212 degrees F) in order to kill any microorganisms present in the food. The time pints or quarts are processed depends upon what is being preserved. More dense foods/recipes require a longer processing time.
How do sterilizing agents destroy bacteria?
BACTERICIDAL
What temp to cook ground pork to?
160 degrees F to destroy all bacteria.
What can be destroy illness causing bacteria?
If you're asking how to destroy food-borne illness, heat potentially hazardous foods to an internal temperature of 165 degrees fahrenheit. This is especially important for chicken, and other meats usually need to be heated only to 145 degrees fahrenheit to kill all of the bacteria that normally exists in them
What is canning in food preservation?
Canning is the process of applying heat to food that's sealed in a jar in order to destroy any microorganisms that can cause food spoilage.
How does E. coli affect beef?
The safety hazard occurs when the E. coli are ground up with the hamburger, and the meat is not cooked at temperatures high enough to destroy the bacteria.
What temperature is used to disinfect utensils?
A temperature of 175 degrees F (80 degrees C) for 5-10 min, for example, will destroy all active bacteria, yeast, and fungi. Cells in their dormant phase (spores) are more resistant to heat, and temperatures above 240 degrees F (116 degrees C) must be used to inactivate them.
Can bacteria destroy crops?
Yes
What does the appendix do in humans?

Why bacteria cannot live at very low or very high temperature?
Bacteria, like all living organisms, function by means of a complicated series of chemical reactions. Chemical reactions happen differently when there is a large difference in temperature. Low temperatures have a particular danger, which is that water freezes and it expands when it freezes, which will cause it to rupture the cell membrane of the bacterial cell. High temperatures cause all sorts of new reactions to occur which would not occur at lower temperatures, and these new reactions will also destroy a cell, even more thoroughly than low temperatures will. In less technical terms, high temperatures will cook the bacteria.
