This is the era of proteins, especially soya proteins. These were launched over 60 years ago by U.S. companies in the mid-Western states where soya is the main crop. The two principal soya proteins are concentrate [75% protein] and isolate [95% protein]. Traditionally these proteins have been produced by U.S. companies, notably Solae [DuPont and Bunge until early 2012 when Dupont acquired the entire stock of this business] and ADM. Chinese companies have entered this area and now account for over one-third of the world output of soya proteins. Although soya beans are an important crop in Brazil and Argentina they have no facilities for converting soya to concentrates and isolates.
A major disadvantage of soya isolates has been their insolubility in beverages at low pH levels. ADM has recently introduced ‘Clarisoy’ an enhanced soya isolate which is soluble in beverages at pH below 4, is heat stable and remains clear without the need to use stabilisers or . This protein finds particular applications in sports and dietetic nutrition.
