A BEGINNERS GUIDE TO BOILIE MAKING
STANDARD BASE INGREDIENTS
SEMOLINA. This is a great carbohydrate (energy) & an excellent carrier for flavours. It is a very cheap ingredient, which is readily available at most supermarkets or health food shops. You can buy white or brown (wholemeal). You can use semolina mixed with one other ingredient like Soya flour and you have the basis of a boilie, In truth a lot of ‘ready made’s consist of semolina and Soya flour.
SOYA FLOUR There are three main types, Soya isolate (85% protein), Soya flour (50% protein) and full fat Soya (37% protein). High in oil content they are another excellent flavour carrier. As a 50/50 semolina/Soya flour, add a flavour and a little sweetener and you have a simple boilie.
I hope this helps to explain why they use them.
Semolina is high in Energy, and Soya Flour is high in Protein and Oil's, and they are both excellent flavour carriers.
