What are the major microbial decomposers of plant and animal material?
Most animals are consumers, very few are decomposers. Examples of decomposers are earthworms, craps, and fungi.
What is microbial enzyme?
Enzyme present in microbes are called microbial enzymes .
What is microbial death?
Microbial death occurs when bacteria run out of nutrients and die.

Example of microbial contamination?
Microbial contamination is the introduction and growth of harmful microorganisms in foods and water, causing food borne illness and even death. Some examples of microbial contamination include botulism, salmonella, and mold.
How do you preserve cereal?
Keep water and oxygen out. Both of these contribute to rancidity reactions and microbial growth. Cereals typically have about 3% moisture, though most of this water is not available for any chemistry to occur. Even so, water within cereal will ultimately lead to rancidity. Sealing your cereal and freezing it is probably your best bet if you want to really make it last.
How you check rancidity?
we can check rancidity thru two methods :- check the smell usually it becomes foul and see if the the fats and oils are oxidized ,if yes then it is rancidity.
What is a major cause of rancidity of lipids in foods is exposure to?
Rancidity is caused by hydrolysis and oxidation. Heat, moisture and exposure to light will increase these chemical reactions and thus increase the likelikhood of the onset of rancidity.
What type of reaction take place in rancidity?
chemical reaction takes place in rancidity
Which two antioxidants which are usually added to fat and oil containing foods to present rancidity?
There are two types of rancidity: oxidative rancidity and hydrolytic rancidity. Citric acid and phosphoric acid are added to prevent rancidity in fats. Other antioxidants include butylated hydroxyanisole (BHA)and butylated hydroxytoluene (BHT).
How do you minimize rancidity?
we could minimize rancidity by adding anti oxidents(which prevents oxidation) to food items.
What are the by-products of rancidity?
rancidity food are very wasted food for our health because there oil and oil are faty

What is oxidative rancidity?
Rancidity is the chemical decomposition of fats, oils and other lipids. There are three basic types of rancidity. Hydrolytic rancidity occurs when water splits fatty acid chains away from the glycerol backbone in glycerides. Oxidative rancidity occurs when the double bonds of an unsaturated fatty acid react chemically with oxygen. Microbial rancidity refers to a process in which microorganisms such as bacteria use their enzymes, including lipases, to break down chemical structures in the fat. In each case, these chemical reactions result in undesirable odors and flavors.
