Pls How do I tell her that she makes vexing Sounds when Eating ?

Eating and slurping noises  gets me truly irate and somebody near me is blameworthy of this habit and not mindful that I can’t stand it. Presently the issue is, how do I tell the individual without offending her? What’s more, is there any risk this habit be can stopped? Do I Tell Her that she makes annoying sounds when eating without hurting her?
