Amino acids may extend sweet potato starch's gelling possibilities

The nature of the amino acid was found to strongly influence the resulting properties of the amino acid, and perhaps allowing for tailored starches for different food applications, suggests the research in the Journal of Food Science. 

Both lysine, a positively-charged amino acid, and lysine, aspartic acid, a negatively charged amino acid, decreased the viscosity of starch paste made from orange-fleshed sweet potatoes
