Ingredient
Soy Protein
Also known as Soy protein concentrate, Soy protein isolate, SPI, SPC
The concentrated and isolated protein fractions of soy, strong water and fat binders used in emulsified and injected products.
Soy protein concentrate and isolate are soy stripped down to mostly protein. That concentration makes them powerful functional ingredients: they bind water and fat, help stabilise an emulsion and firm a slice, which is why they turn up in frankfurters, injected hams and reduced-fat products. The isolate is the purest and most functional, and the most neutral in taste.
