Hi
If I was making baits I would source potassium sorbate, Ive tried nutrabaits and agree with whats been said it dont preserve for long and is quite costly.Potassium sorbate has been tested and tested till the cows come home and it's never been proved it was bad for animals or humans
infact potassium is a type of salt and sorbate comes from the rowan berry.Many foods use them, anything thats not frozen and has pastry case. I dont know the volumes that bait companies would use but say 50 kilo's of bait would be something like a half kilo of potassium sorbate
dont quote me on that though.But having said all that a frozen bait takes some beating, has a better smell then shelf lifes and I believe is more attractive to them carpio,s.
By the way did you know potassium sorbate has been in use since 1900,,ish just thought I'd mention that
