Which is TRUE concerning "food systems"? a. A food system is a dispersion containing two phases: a continuous phase and a dispersed phase. b. In a typical food system, solids, liquids, and gases are dispersed within other solids, liquids, and gases. c. Intermolecular bonds such as hydrogen bonds are not present in food systems. d. Both (a) and (b) choices e. (a), (b) and (c)

Both (a) and (b) choices.

Explanation:

Food system in chemistry may be defined as the process of the interaction of the chemical and biological component of food. The chemistry in food is different biomolecules and biological component is lettuce and meat.

The food system shows two main phases like dispersed phase and continuous phase. Dispersed phase includes the substance that are dissolved in the dispersion medium. Three phases of system known as solid, gas and liquid are mixed with each other and makes the system stable. The hydrogen bonds play important role in the food system.

Thus, the correct answer is option (d).
