S. K. SATHE, Dept. of Nutrition, Food & Exercise Sciences, Florida State Univ., 402 Sandels Bldg., Mail Code 1493, Tallahassee, FL 32306-1493 Animal proteins typically contain all of the essential amino acids required by humans, are highly digestible, are bioavailable, and possess excellent functional properties suitable for food applications. For these reasons, animal proteins have received considerable scientific scrutiny for well over one hundred fifty years. However, animal proteins being expensive are not affordable for many people. Strict vegetarians also do not consume animal proteins. As a consequence, a vast majority of the global population has to depend on proteins obtained from edible seeds of cereals, legumes, fruits, and nuts to satisfy its dietary proteins needs and requirements. Edible seeds are also an important and significant source of proteins used in livestock production as well as pet animal foods manufacture. Edible seeds contain metabolic and storage proteins. Seed storage proteins are typically classified based on their solubility in different solvents or by sedimentation velocity (S). Most seed storage proteins have S values in the range 2-14S. Advances in biochemical and analytical methodologies, particularly during the later half of the 20th century, have improved the precision with which proteins can be investigated at molecular level. Seed protein research has a focus in three major areas: 1. nutritive value , 2. functional properties, and 3. safety. Recent research efforts are focusing on role of edible seed proteins in human health with respect to both beneficial and adverse effects.
