proteins have also been criticised for their taste, as they contain a compound called saponins, which can produce a bitter and metallic taste. Texture Depending on the method of processing, pea protein can have a gritty texture. Composition Depending on the method of processing, some pea proteins can contain high levels of anti-nutritional properties such as phytates, lectins, and trypsin inhibitors, which have negative side effects. Saponins and phytates may exhibit hypocholesterolaemic and anticarcinogenic activities. Trypsin inhibitors decrease the digestion of the protein. Lectins can impede the uptake of glucose, decrease nutrient transport, and create damage to the mucosal layer of the intestines by binding to carbohydrate molecules. Phytates affect the bioavailability and digestibility of the protein by forming complexes with essential dietary minerals such as Iron, Zinc, and Calcium, affecting their absorption.
