Amino acid and fatty acid compositions of texturized vegetable proteins

Abstract

Texturized proteins are the main ingredients of meat analogues. This paper evaluated the amino acid and the fatty acid compositions of texturized proteins produced by pea isolates, soy isolates, or dry-fractionated pea proteins, all combined with oat proteins. The nutritional composition was significantly affected by the protein sources. All the texturized proteins had a balanced amino acid profile, complying with the recommendations by FAO/WHO, except for the sulfur amino acids. The fatty acid profile showed the predominance of the polyunsaturated fraction, which was the highest in the dry-fractionated pea mixes. The trans-isomers’ content was lower than 0.5%.
