Powdered sugar tastes off

Ever find that your powdered sugar has a soapy taste and any idea why this would be the case? I;ve noticed it particularly with one brand, but I'm not sure it's brand-specific. Thanks.

I got 2 bags of powered sugar from Meijer, their brand 2 different dates and they both taste soapy, they expired 3 months ago, does anyone know what happens to make the sugar taste like that

I’m having the same problem! I usually don’t buy cheap powdered sugar but it was at the store down the street so I got 2 big bags and now all my frostings tase like chalky soap it’s clover valley I have cornstarch taste it it’s exactly what the taste is it overpowers my cakes now how much cornstarch are they using is the question. If more then 3 percent I’m going to be mad because there’s no reason for anymore then that it really starts effecting the taste after that. I’m glad I’m not the only one who had this problem I thought I was going crazy.

I experienced the same thing! I thought I was going crazy. It was a cheaper brand so I guess it could be the corn starch, but I've never tasted anything like it before. Tasted terrible!

i mean not sure why it would taste soapy! cornstarch is anti-caking, like Grenstuff said, making the 10x fluffy and light.

Powdered sugar contains cornstarch. Not sure why, but maybe that's the culprit? Curious what the ingredients are in that one particular brand.

Powdered sugars have anti-caking agents. It wouldn't surprise me if they varied enough between brands that you could detect them.
