Recently I picked up a few different types of emulsifiers in bulk powder form when I saw them in passing at a catering wholesaler.
Having never used powdered emulsifiers before in cooking or baking, I figured I'd find pretty comprehensive instructions for their use on the web - but I can't.
I'm not a stranger to food science but nor am I a chemist. I understand that emulsifiers are at least sometimes prepared by pre-mixing them into a (heated?) liquid or fat and then using the resulting solution in the actual recipe, which may explain why a lot of commercial emulsifier mixtures are packages as tubes of gel or paste.
I've also checked several industry-level textbooks about emulsifiers and while they are fantastic for in-depth explanations of the chemistry behind each emulsifier, they do not (as you might imagine) provide guidance on how a lowly baker or cook would actually use a powdered form.
So does anyone know how to prepare and use a dry powdered form of any of the following in a real recipe?
Specifically I am most interested in enhancing baked goods and adding stability to sauces, but would also like to know how to use them for other processes such as sausage-making too.
- E471 Mono- and diglycerides of fatty acids
- E481 Sodium stearoyl lactylate
- E482 Calcium stearoyl lactylate
- E472e DATEM (diacetyl tartaric acid ester of mono- and diglycerides)
