Sources of dried ingredients: Hummus, Refried Bean

Anyone have sources of instant dried hummus, instant dried refried bean mix? While I'm at it, is the only source of freeze dried mince and egg powder in NZ those 160g packs from BCC? By the way, have had success so far with making my own cheese powder. Started with grated mozzarella from the supermarket, divided it and stapled in inside a couple of pouches made of handi towels, hung them in the kitchen where warm dry air from the wood burner wafts past. A shake every few days for a week till all of it rattled, then turned it to powder in the blender.
