CONCLUSION * this tenn is defined in the textbook chapter glossary CHAPTER 4 Starches in Food LEARNING OBJECTIVES The reader will be able to: 1. Identify sources of starch, including cereal grains, roots and tubers. 2. Describe the structure and composition of starch, including amylose and amylopectin .
