I'm not convinced and I don't actually think that it matters one bit whether the flavor or attractant is either naturally derived or artificial - if the chub want it they will have it, simple as that, provided you put it in the right place to begin with of course!
If you want to add some cheese powder to your bread (preferably liquidized) then you have a few options at your disposal.
1. Buy a packet cheese sauce from the supermarket and add that.
2. Buy some blue cheese powder from a bait supplier such as ccmoore (1kg will last you years!)
If you want to go down the liquid route then there are some very good cheese flavors on the market. Nutrabaits Cheese Elite is one of the best as is Richworth's Blue Cheese but imo, the best cheese flavor ever produced was Hutchy's Smelly Cheese. Don't know why but that flavor stood head and shoulders above all others and continues to do the business even today.
The sky is the limit when it comes to flavors so let you imagination run wild. Some times some really unusual flavor combinations work the best. Think outside the box! For chub I rate cheese and cheese flavored baits are at the top of the list closely followed by fishy and spicy flavors.
Note - John Bakers Taste Liquid food smells absolutely disgusting (like liquid vomit) but is a highly effective additive to you bread mash.
Try mixing it with some Spectrum Milk & Cream and a touch of garlic for a superbly creamy cheesy garlic flavored additive. Smell like some one has puked in your bucket of mashed bread but the chub love it as the milk and cream makes a lovely cloud in the water which draws them from a long way downstream.
