It's a lab, I'll do it as an effervescent tablet but I do not like lemon flavor

Hello, I need help to make a citric acid solution in water taste-free or at least not sour. I understand that it is the Oxonium ions formed in aqueous solution that provides the sour taste. I wonder if there is any substance that causes the sour taste to cease? The fluid should be drinkable ie I should be able to drink it without it being harmful in any way.
