I'll tell you a true story about artificial sweeteners, Robert.
When I was a student, I spent a couple of very enjoyable summers working in an electroplating factory. One of the things we chrome plated were the reflectors on Baxi Bermuda gas fires, if you remember those. This was done in a bath of boiling chromate solution, 1200 gallons of it. The long reflectors were quite thin and bendy steel. If you pulled out the reflectors after plating, and bent them while hot, the chrome plate cracked and flaked. The way to prevent this was to stick the contents of a 2kg bag of white powder into the chromate bath. With this, the hot plated metal could be bent and flexed without a sign of cracking.
What was this magic powder? Saccharin. The foreman used to put it in his tea.
