When I create a new colony in version LU-359645 and discover nosh beans for the first time, "nosh bean" is added as an item type under the "seeds" category, but not the "cooking ingredients" category. Annoyingly, this makes it impossible to refrigerate them.
A savegame from august 13th from a colony that had already already discovered nosh beans has them listed under both the "seeds" and "cooking ingredients" categories, so I think this is likely a recent regression.
Create a new colony. Use the sandbox tools to spawn a nosh bean next to your duplicants. Expand the "cooking ingredients" item category in either the item HUD or the item filter for a refrigerator/ration box.
