What chemical characteristics of fatty acids determines their susceptibility to spoilage by oxygen?
Susceptibility to spoilage by oxygen of fatty acids is determined by the number of double bonds in the acid's carbon chain. Molecular oxygen can attack these bonds and break the chain, forming ketones. Incidentally, naturally-occuring cis-double bonds are more susceptible than the artificial trans-fatty acids.

How does the amount of fat in milk affect the amount of spoilage?
The amount of fat in milk can influence its susceptibility to spoilage. Higher fat content can provide a more favorable environment for bacteria to grow, potentially increasing the rate of spoilage. Additionally, fat can oxidize over time, leading to off-flavors and rancidity in the milk.
Is food spoilage a physical change?
There are several changes that occur that cause food spoilage. A loss of ph, spoilage caused by bacteria and decomposition are contributing factors to food spoilage.
What chemical property does sliced fruit have?
Sliced fruit can undergo enzymatic browning, where enzymes in the fruit react with oxygen in the air to produce brown pigments. This process can affect the appearance and flavor of the fruit. Additionally, slicing fruit increases its surface area, allowing for faster oxidation and spoilage.
What is the difference between spoilage and contamination?
Spoilage refers to the physical or chemical changes that make a product unsuitable for consumption, usually caused by microorganisms or environmental factors. Contamination, on the other hand, refers to the presence of harmful substances or microorganisms in a product, which can pose health risks to consumers. In summary, spoilage renders a product unpalatable or deteriorated, while contamination makes it unsafe for consumption.
Is Antioxidants are used as food preservatives in margarine a chemical or physical property?
Antioxidants being used as food preservatives in margarine is a chemical property because it involves the interaction of the antioxidants with the molecules in the margarine to prevent oxidation and spoilage.
Difference between chemical spoilage and mechanical spoliage?
Example: a block of cheese has grown moldy. This is chemical spoilage. A block of cheese falls on the floor. This is mechanical spoilage.
Is food spoilage is a chemical change?
CHEMICAL CHANGE
How do you prevent chemical spoilage?
by eating chemicals
Which chemical is addied which prevent spoilage of cold drink?
Benzoic acid is added to prevent spoilage of cold drinks
How does the amount of fat in milk affect the amount of spoilage?
The amount of fat in milk can influence its susceptibility to spoilage. Higher fat content can provide a more favorable environment for bacteria to grow, potentially increasing the rate of spoilage. Additionally, fat can oxidize over time, leading to off-flavors and rancidity in the milk.
A chemical which is added to food to retard spoilage is called?
preservative
Is food spoilage a physical change?
There are several changes that occur that cause food spoilage. A loss of ph, spoilage caused by bacteria and decomposition are contributing factors to food spoilage.
How do enzymes cause food spoilage?
There are enzymes that speed up the chemical reaction components in food which leads to spoilage. Enzymes can be slowed down so that food spoilage doesn't occur as quickly by keeping food in cold temperatures.
What is spoilage of orange fruits?
All food and drink have the bacteria in them already that begin to spoil or break down or decay the matter. Refrigeration or chemical additives merely slow down this natural timetable for decay.
What chemical property does sliced fruit have?
Sliced fruit can undergo enzymatic browning, where enzymes in the fruit react with oxygen in the air to produce brown pigments. This process can affect the appearance and flavor of the fruit. Additionally, slicing fruit increases its surface area, allowing for faster oxidation and spoilage.
Why food spoilage is more in summers than winters?
food spoilage that is caused by bacteria is faster the warmer the food is. It is generally so that chemical reactions - which go on in bacterial systems - speed up as temperature rises. That is why we keep food in fridges and freezers.
Why is spoiling food a chemical change?
Food spoilage is a chemical change because it is caused both by oxidation of fats and the chemical changes involved when fungi and bacteria use enzymes to use the food for its own development.
