Kev I don’t think an EA flavour would emit a food signal there’s no food value to it…..and it wouldn’t be in your bait long enough unless you are casting every 10 mins
I use low levels in all my bait but you are right about the base mix doing all the work anyone using low value baits are making it hard for themselves … I think there is a difference with bait if you are fishing rivers as opposed to lakes the application is completely different ……the main thing for me when applying baits to a river is solubility I like it to break down very quickly
All flavours emit a food signal that’s the whole point of them , wether alcohol or glycol based , that packet of cheese an onion crisps I ate yesterday didn’t have any cheese or onion in there but cleverly made up flavours that just want me to eat the whole packet in seconds !
There’s a massive industry making foods with ingredients that want us to eat more and more , that’s what Taste F2 is based on . Also making us all fat and unhealthy.
Flavours emit a food signal and create a better tasting food with better palatably at the same time .
A good flavour can still be smelled in a bait even after it’s been out in the water for hours , even one buried in silt .
In your case the flavour is probably the label and as Rich as proved isn’t needed when the base mix gets accepted and they know it’s a better food source than anything out there .
I used to put strawberry flavoured Angel Delight in base mixes , now I realise it worked because the strawberry flavour in there was soluble and designed to be mixed with milk , I didn’t realise this at the time but the bait boffins knew this and capitalised on it .
Scopex was another flavour that was designed on fruit turning in the autumn , Rod realised the birds would know when an apple was just turning from sugar to alcohol and based the flavour on this , it turned out to be one of the greatest flavours of all time and this was over 40 years ago ! And still used today . He was using flavours like Monster Crab Chocolate Malt in 50/50 mixes in the Colne valley as living in Lincolnshire made it impossible to prebait thus relying on the flavour to do all the work.
So I don’t think we can say flavours are just a label , they play a massive part in bait formulation and sending out the right food signal at the right levels .
