Soybean meal (SBM) is a co-product of soybean oil extraction mostly used as animal feed due to its protein content ranging from 40 to 49%. Additionally, SBM contains 35-42% of carbohydrates, half of which are structural, and the remaining consists of approximately 17% of mono- and disaccharides--especially sucrose--up to 8% oligosaccharides, and 1-2% starch. When used as animal feed, only sucrose and starch are digested and absorbed by monogastric animals. Although SBM contributes carbohydrates to their diet, its main function is to provide proteins. Therefore, the selective removal of carbohydrates would create a protein-enriched meal with a greater value, which …
