Soybean meal carbohydrates composition

Recent applications of HPAEC-PAD are many and varied. A representative list includes quantitation of polyglucose metabolites in plasma of dialysis patients,148 analysis of heat-treated milk,149 carbohydrate content in lipopolysaccharides,150 phosphorylated sugars in tissue samples,151 composition of soybean meal,152 carbohydrate composition of recombinant modified tissue plasminogen activator,153 analysis of cyclization products from an enzyme reaction,154 carbohydrate content of glycoconjugate vaccines,155 and monitoring of patients with rheumatoid arthritis.156... 

Traditionally, soybeans (SB) are used as food and feed ingredients for their protein content and protein composition. As a protein source, SB often are used in the form of soybean meal (SBM), which is the product of SB processing for SB oil extraction. The carbohydrate content and carbohydrate composition of SB and SBM have received limited attention compared to their protein and fat constituents. Nevertheless, carbohydrates make up a significant part of the SB seed. Typically, SB contain approximately 30—35% carbohydrates (Snyder Kwon, 1987 NRC, 1998). In SBM, carbohydrate content may be as high as 40% (NRC, 1998).

Typically soybean proteins contain 38-42% crude protein, 16-20% triglycerides, and around 33% carbohydrates, on dry basis. Soy proteins are the isolated proteins from soybean. It is made of dehulled, defatted soybean meal. The structural characteristics of soy proteins give them potential for industrial applications in plastics and reinforced composite materials.
