What else can I help you with?
Two reasons why the process of canning food kills microbes?
Because of the heat used to can the food.
What are the effects of moist heat on protein?
When moist heat is introduced to a piece of meat, the protein collagen is converted into gelatin(which is also a protein). This makes the meat more soluble in our bodies.
What does it call when all the microbes have been killed by radiation and heat?
Dead Microbes.
What term means all microbes have been killed by radiation or heat?
"sterile" means that all microbes have been killed by radiation or heat.
When all the microbes have been killed by radiation or heat?
Your question is not very clear. Microbes can be killed by radiation and heat. It depends on the amount of each and the duration. Viruses are not considered to be microbes but are infectious particles. They can also be inactivated by heat and radiation, especially UV light, but not by cold.
How does canning food kill microbes?
There is no air or heat in the can.
What does heat do to the DNA polymerase?
Heat denatures protein. DNA polymerase is an enzyme and a protein.
Some examples of unusual places in which you can find microbes?
extreme heat and toxic sulfur
How should foods be cooked?
Food should be cooked by heat which can be any type of cooking method like grilling, boiling, etc. The advantage of doing this is to kill harmful microbes in the food. High temperature(heat)=killing harmful microbes.
Why does jam not spoil when left outside the refrigerator?
because the jam is heat treated before sealed and so has no microbes on it, even when you open it the high amount of sugar dries out the microbes, which then kills them (see below) the sugar is a solute and the jam is the solution. also jam is viscous so it slows them down while the sugar kills them
Does exposing a protein to heat break peptide bonds?
Yes. If enough heat is applied the protein breaks down. This is called denaturing the protein if I recall correctly.
What is the main function of the autoclave?
An autoclave is an instrument used to sterilize labware through moist heat. This process effectively kills any microbes that may be residing on labware.
