بروتين الصويا is a protein that is isolated from soybean. It is made from soybean meal that has been dehulled and defatted. Dehulled and defatted soybeans are processed into three kinds of high protein commercial products: soy flour, concentrates, and isolates. Soy protein isolate has been used since 1959 in foods for its functional properties.
يُنظر إلى بروتين الصويا عمومًا على أنه يتركز في أجسام البروتين ، والتي يقدر أنها تحتوي على 60-70% على الأقل من إجمالي بروتين فول الصويا.Upon germination of the soybean, the protein will be digested, and the released amino acids will be transported to locations of seedling growth. Soybeans contain a small but newly very significant 2S Albumin storage protein.Legume proteins, such as soy and pulses, belong to the globulin family of seed storage proteins called legumin and vicilins, or in the case of soybeans, glycinin and beta-conglycinin. Soybeans also contain biologically active or metabolic proteins, such as enzymes, trypsin inhibitors, hemagglutinins, and cysteine proteases very similar to papain. The soy cotyledon storage proteins, important for human nutrition, can be extracted most efficiently by water, water plus dilute alkali (pH 7–9), or aqueous solutions of sodium chloride (0.5–2 م ≈ 30-120 جم / لتر) من فول الصويا منزوع الدهن والقشور الذي لم يخضع إلا لأدنى حد من المعالجة الحرارية ، لذا فإن البروتين قريب من كونه أصليًا أو غير مألوفد.
