Methanol (also called methyl alcohol and wood spirit, amongst other names) is an organic chemical compound and the simplest aliphatic alcohol, with the chemical formula C H 3 OH (a methyl group linked to a hydroxyl group, often abbreviated as MeOH).
Denatured alcohol is used as a solvent and as fuel for alcohol burners and camping stoves. Because of the diversity of industrial uses for denatured alcohol, hundreds of additives and denaturing methods have been used. The main additive usually is 10% methanol (methyl alcohol), hence the name methylated spirits.
However, because the formation of PhIP in cooked meat items is dependent on temperature, cooking time, and cooking method, variations do occur in the direct measurement method. [12] Direct measurement methods have determined dietary intake levels of PhIP to range from 0.07-4.3 ng/kg per day.
The same principle applies when baking soda is used to boil pretzels before baking. The pantry staple can also serve as a tenderizer for certain ingredients—like meat and even canned chickpeas .
The oxidation products derived from methyl are hydroxymethyl group −CH 2 OH, formyl group −CHO, and carboxyl group −COOH. For example, permanganate often converts a methyl group to a carboxyl (−COOH) group, e.g. the conversion of toluene to benzoic acid. Ultimately oxidation of methyl groups gives protons and carbon dioxide, as seen in ...
The notation "hydrated compound⋅n H 2 O", where n is the number of water molecules per formula unit of the salt, is commonly used to show that a salt is hydrated. The n is usually a low integer , though it is possible for fractional values to occur.
During the process itself, conditions such as temperature, duration, water content, redox potential, and salt content all have an effect on the meat. [14] The salt content in dry-cured ham varies throughout a piece of meat, with gradients determinable through sampling and testing or non-invasively through CT scanning. [17]
The name is derived from Low German mett for "chopped pork meat without fat", or Old Saxon meti for "food". It consists of minced pork meat, generally seasoned with salt and black pepper, regionally also with garlic or caraway, and eaten raw. It is also possible to add chopped onion, in which case it is known as Zwiebelmett (onion mett).
