Food chemistryis the study of chemicalprocesses and interactions of all biological and non-biological components of foods. [1][2]The biological substances include such items as meat, poultry, lettuce, beer, milkas examples. It is similar to biochemistryin its main components such as carbohydrates, lipids, and protein, but it also includes areas ...
There are three principal classes of macronutrients: carbohydrate, protein and fat. [1] Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per ...
The use of nitrites in food preservation is highly controversial [23] due to the potential for the formation of nitroso-compounds such as nitrosamines, N-Nitrosamides and nitrosyl-heme. [citation needed] When the meat is cooked at high temperatures, nitrite-cured meat products can also lead to the formation of nitrosamines.
A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical ...

For example, the industrially important pentasodium triphosphate (also known as sodium tripolyphosphate, STPP) is produced industrially by the megatonne by this condensation reaction: 2 Na 2 HPO 4 + NaH 2 PO 4 → Na 5 P 3 O 10 + 2 H 2 O. Phosphorus pentoxide (P 4 O 10) is the acid anhydride of phosphoric acid, but several intermediates between ...
