Questions about Soy protein isolate
How much soy protein isolate should you add to a shake?
A typical serving is about 28 g; blend it with liquid rather than stirring it in, which helps prevent lumps. That portion provides 25 g of protein.
How do you stop soy protein isolate from going lumpy?
Put the liquid in the blender or shaker first, add the powder gradually, then shake or blend until smooth. For a hot soup or sauce, first whisk the powder into a little cold water to make a paste, then stir it in.
Can you bake with soy protein isolate?
Yes, but it absorbs liquid and can make bakes firm or dry. Replace only a small part of the flour, and add a little extra liquid; it works best in pancakes, muffins and savoury bakes rather than as a one-for-one flour substitute.
How should you store soy protein isolate after opening?
Keep it tightly sealed in a cool, dry cupboard, away from steam and direct sunlight. Use a dry scoop, and follow the packet’s guidance once opened.
Can you use soy protein isolate instead of textured soy protein?
Not as a direct swap: isolate is a fine powder for mixing into drinks and recipes, while textured soy protein is made into pieces that soak up liquid and give dishes a chewy, mince-like texture. Textured soy protein has 45.9 g of protein per 100 g, compared with 88 g in soy protein isolate.
Is soy protein isolate suitable for someone with a soy allergy?
No. It is made from soya and can trigger a reaction; avoid it if you have a soy allergy, and check ingredient information on foods made with it.
