3. Eyes recieve the first impression of foods: shapes - colors - consistency - serving size - and the presence of any outward defects. Color can be decieving and effect choices by consumers. color palette of foods on a plate contributes to or detracts f

6. Triglycerides (fats and oils) - phospholipids - and sterols.

7. 95 percent of all lipids. consist of three fatty acids attatched to a glycerol molecule.

8. Disaccharide. table sugar. is one glucose and fructose molecule linked together.

9. Hydration - denaturation/coagulation - enzymatic rections - buffering - browning.

10. A procedure in which pure liquid is obtained from a solution by boiling - condensation - and collection of the condensed liquid in a separate container.

11. Sugars - starches - and fibers found in foods - Can be good - bad - simple and complex. made up of carbon - hydrogen - and oxygen. synthesized through phtosynthesis.

12. Indigestible polysaccharide that are held together by bonds that the body cannot break down. most fibers therefore pass through the body without providing energy. found in plant origin foods especially cereals - veggies and fruits.
