Fats are hydrogenated to make them solid at room temperature. Animal fats like butter and lard are naturally hard at room temperature. Butter doesn't have to be hydrogenated, so they don't bother. Most lard is hydrogenated so you can keep it at room temperature without it spoiling, but some really fancy lard is left unhydrogenated and kept in cold storage.

When liquid oils are turned into solid fats through a process?
This process is called hydrogenation.
How do you prepare cyclohexane from benzene?
Catalytic hydrogenation
Are polymers broken down by the process of hydrogenation?
no.
What is the role of quinoline in the hydrogenation of alkynes?
Quinoline "poisons" the Lindlar catalyst, thereby enhancing its selectivity. This prevents the hydrogenation reaction from going from the alkyne to the alkane, and instead from the alkyne to the alkene.
What is the chemical name for the process hardening vegetables oils?
Hydrogenation
What happens during the hydrogenation of ethylene?
2-ethylhexane. This is because the hydrogenation causes the double bonds to be replaced with an H-H to fill the carbons valence vacancies.
What is hydrogenation and why is it done?
Hydrogenation is the proccess that makes unsaturated fat have characteristics of saturated fat. During the process the shape of the fat molecule changes for cis to trans form. This process increases the risk of heart disease.
Why are cis fatty acids rearranged to trans fatty acids in the process of partial hydrogenation?
CIS fatty acids are the most common form. They rearrange to form trans fatty acids during the hydrogenation of edible oils.
How can you use the word hydrogenation in a sentence?
Margarine is produced by the hydrogenation of vegetable oils.
The hydrogenation of 2-methylpropanal gives the product?
hydrogenation of 2-methylpropanal gives
Can pt and pd be used in the hydrogenation of alkenes?
Pt and Pd can be used as catalyst in the hydrogenation of alkenes or (de)hydrogenation of hydrocarbons (cracking in petrol industry)
What is the process of fat hydrogenation?
The process of fat hydrogenation involves a high temperature and the involvement of a metallic catalyst. The metallic catalyst either increases or decreases the number of the chemical bonds within the molecules of the substances.
What happens to butter if you warm it up?
...butter melts when you warm it up
When liquid oils are turned into solid fats through a process?
This process is called hydrogenation.
If Trans fats are inadvertently formed during the hydrogenation of vegetable oils is the hydrogenation of oils an oxidation or reduction reaction?
The parital hydrogenation of oils and fats reduces the cis double bonds in fats to give them a more solid form at room temperature. As the reduction process takes place at high temperatures, there is thermal isomerization of some of the cis bonds to their trans form.
The advantages and disadvantages of hydrogenation?
The advantage to hydrogenation is that food does not go rancid as quickly and maintains its physical properties at room temperature. Hydrogenated food such as shortening and peanut butter can last for years without going bad.The disadvantage is that through the process of hydrogenation saturated fats increase and trans-fat increases. This contributes to an elevation of LDL Cholesterol (bad cholesterol) and a decrease in HDL cholesterol (good cholesterol) resulting in increased health risks for such things as heart diease.
what happens if you mix peanut butter and jam?
That is what you do to make a "peanut butter and jelly" sandwich.
