An Introduction to the Physical Chemistry of Food (Food by John N. Coupland

By John N. Coupland

Familiar mixtures of elements and processing make the constructions that provide nutrition its houses. for instance in ice cream, the emulsifiers and proteins stabilize in part crystalline milk fats as an emulsion, freezing (crystallization) of a few of the water offers the product its hardness and polysaccharide stabilizers retain it delicate. Why assorted recipes paintings as they do is basically ruled via the principles of actual chemistry.

This textbook introduces the actual chemistry necessary to realizing the habit of meals. beginning with the easiest version of molecules attracting and repelling each other whereas being moved by way of the randomizing impression of warmth, the legislation of thermodynamics are used to derive vital homes of meals corresponding to taste binding and water job. such a lot meals comprise a number of stages and an identical molecular version is used to appreciate part diagrams, section separation and the houses of surfaces. the remainder chapters concentrate on the formation and homes of particular buildings in meals – crystals, polymers, dispersions and gels.

Only a uncomplicated realizing of nutrition technological know-how is required, and no arithmetic or chemistry past the introductory collage classes is needed. in any respect levels, examples from the first literature are used to demonstrate the textual content and to focus on the sensible functions of actual chemistry in nutrients science.
