What happens chemically when edible oils become rancid?

some triglyceryl esters (that is what oil is) are split and release free fatty acids. second by the influence of light and oxygen the double bonds in unsaturated fatty acid chains are attacked, and first by forming peroxides, and later aldehydes and ketones evolve a rancid taste. third the double bonds can be recombined intermolecularly giving rise to polymerization, just like in plastics.

Hydrolysis of an unsaturated fatty acid would cause saturation. Products would be saturated fatty acid and oxygen

friend,since there are some air molecules present in the flour with water,when it is dropped into oil the air inside it will expand raising the surrounding layer,puffing can be induced more by adding soda powder to wheat flour

The oil will become contaminated with hydrocarbons.

I just heard the other day that castor oil isn't good for you. I don't know for sure but you might want to check it out first.

Solvents which are harmless to human beings. No health effects.\nThis product (food grade solvent) needs to be approved by NSF international (National Sanitation Foundation,USA). The approval is mandatory.

It depends on the damage to the tissue of the animal that's left. If something smells like a burnt log it's probably not edible.

mix vinegar and baking soda.  a chemical reaction will take place.

This is an esterification, \nButanoic Acid (CH3CH2CH2CO2H)+ ethanol (HO-CH2CH3), in basic media, yields ethyl butyrate. \n\nCH3CH2CH2CO2H + HO-CH2CH3 --> CH3CH2CH2COO-CH2CH3

None.  Fix your diet.  It's healthier and will last longer.

Anythings excessive cause toxic in our system.you need. plenty of water to flush them out.Too much oil cause us to become fat and put a heavy load on the liver,.too much protein put a heavy load on the kidney,too much sugar will lead to diabetes,\ntoo much acidic food is bad for the digestive system,too much meat is bad for the intestine so you need to balance with vegetable and so forth.

Flaxseed oil in gel caps has a slightly unpleasant odor anyway which can increase over time, but unless it is more than a few months old, it should be fine.

seawater.  a general rule of thumb that surprisingly works every time so far that I've tried it is edibles are acids, anything inedible is a base.  anyone of those are edible (stomach fluid is an acid flat out anyway) except for seawater.  'sides, we discovered sea water was a base last year.

Trans fats occur in manufactured foods during the process of partial hydrogenation, when hydrogen gas is bubbled through vegetable oil to increase shelf life and stabilize the original polyunsatured oil. The resulting fat is similar to saturated fat, which raises "bad" LDL cholesterol and can lead to clogged arteries and heart disease. \nUntil very recently, food labels were not required to list trans fats, and this health risk remained hidden to consumers. In early July, FDA regulations changed, and food labels will soon begin identifying trans fat content in processed foods.

Mineral oils are long chain hydrocarbons, and do not saponify at all...vegetable oils are esters, so NaOH breaks them down to the Na salt of the carboxylic acid and glycerine (usually).

Not if they contain animal fats like lard.
