What you need to look for is a pantry slide not a drawer slide.

I have a 24" deep pantry closet that I'd like to install slide out shelves
in. I'm looking for a full extension, center mount drawer slide to use. I
really would prefer to not have the slides mounted on the side of the
shelf. The slide out shelf would be mounted on the existing fixed shelf
which extends behind the door opening. The center mount slide would have to
be heavy duty (for canned goods) and I guess I could use two slides per
shelf if necessary. In checking most online catalogs I could only find 3/4
extension slides in the 25 pound capacity range. Thanks for any help!
