Does one have to remove kitniyot from their location on Pesach? What about kitniyot derivatives itself and /or found in foods? Like high fructose corn syrup found in soda, etc?
There is no need to remove kitniyot from their location on Pesach.
The prohibition only relates to eating, and not to keeping.
Of course, it is a good idea to put the kitniyot away somewhere that it will be “out of the way” for the duration of Pesach.
