  • Cooking food materials may typically include (at least) three phases. In a first heating up phase the food materials are heated up to a boiling point. In a second boiling phase the food materials are boiled until they are thoroughly cooked and become soft and (partly) decomposed. During the second boiling phase water is evaporated and the food materials and/or nutrients of the food materials get concentrated. Depending on the amount of liquids left, two different situations can be distinguished: a. still including a significant amount of liquid, for example in the case of a soup or stewed food and b. the liquid being almost evaporated, for example in the case of jams or risottos.
