Cooking of foods

Proper cooking of foods is essential. Supervision of hand washing by children in day-care centers and exclusion of symptomatic children may reduce person-to-person spread. 

Although it is usually considered that mastication and digestion are the first processes in the conversion of food into suitable components to be absorbed by the body, cooking of food is also very important it makes the macronutrients and micronutrients more readily available for... 

Thiamin is unstable at high pH90 91 and is destroyed by the cooking of foods under mildly basic conditions. The thiol form undergoes hydrolysis and oxidation by air to a disulfide. The tricyclic form (Eq. 7-19) is oxidized to thiochrome, a fluorescent compound... 

Many of the reactions between foodstuffs take place under mild conditions in processing, storage, and cooking of foods. 

One might note that food tables are not extremely accurate. The lev els of specific nutrients can vary by several-fold, depending on methods for storage and cooking of food, plant variety, breed of farm animal, minerals in the soil used to grow the plant fol, and method of nutrient analysis. 

The water in a pressure cooker boils at a temperature greater than 100°C because it is under pressure. At this higher temperature, the chemical reactions associated with the cooking of food take place at a greater rate. 

The cooking of food materials is a very old method for the preparation of food and for the creation of flavor. Heat creates aroma and taste components for foodstuffs where none existed previously. The science of that transformation is reported in many books and research articles and this knowledge will be enhanced with the information in this chapter. The scientific basis of the chemistry of the thermal development of these flavors is of great interest to flie flavor industry and serves as a source of knowledge in building flavors that are... 

Extruders are in common use for the processing of polymers, as in the spinning of synthetic fibers. They are also used for the extrusion cooking of foods, such as ready-to-eat breakfast cereals. They are not part of the standard equipment of the usual chemical laboratory, yet they offer considerable promise for running reactions without solvent on a continuous basis.
