Restructured steak is a catch-all term to describe a class of imitation beef steaks made from smaller pieces of beef fused together by a binding agent. Its development started from the 1970s. Allowed food-grade agents include: * Sodium chloride (table salt) and phosphate salts. Salt can prevent microbiological growth and make myosin-type proteins more soluble. The allowed amount of phosphate in end products is 0.5% in the U.S. It increases the emulsification of fat. * Animal blood plasma * Alginate: Sodium alginate forms an adhesive gel in the presence of Ca2+ ion. * Transglutaminase: an enzyme that helps the forming of cross-binding proteins. == Problems == Oxidation and food poisoning are the two most serious issues generally associated with restructured steak. To reduce the risk of food poisoning, restructured steaks should always be cooked until well-done. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Restructured steak」の詳細全文を読む スポンサード リンク
