Sorbitan Monostearate in Baking Yeast

January 11, 2011, by Debra Lynn Dadd

Question from KCribley

Recently I discovered that the baking yeast I purchase (and most of them that I looked at) have Sorbitan Monostearate added.

I am a very frequent baker/breadmaker (almost every day) and wonder if I need to be concerned about this ingredient.

I did a bit of online research and saw the MSDS but wasn't sure what to take from it. Some sites say it's safe, others say it's toxic (in large quantities, I assume).

Your thoughts?

Thank you so much for your help!

Debra's Answer

I couldn't find any adverse effects.

November, 2020 Update:  In 2017, the European Food Safety Authority (EFSA) re-evaluated this food additive and determined the acute toxicity of sorbitan esters to be very low.
