Designing a Controlled Solubility Boilie
Many of the articles on my blog are written to share the consulting work I often do for anglers looking to improve or develop specific bait projects.
Most of this consulting is done completely free of charge, simply because I enjoy contributing to the development of new ideas and interesting products within carp fishing.
Occasionally, bait companies also contact me for support and technical advice. If I find the project stimulating, I’m always happy to contribute.
In this article, I want to present the consultancy work carried out for Marco Galletti, owner of the rolling service company Boiliesroom.
I had already collaborated with the company in the past through a series of articles dedicated to rolling services, which also involved CBS Carpfishing and Bools. In those projects, I commissioned the production of three different types of bait to test and demonstrate the effectiveness of this kind of custom-made product.
The Goal of the Project
Marco contacted me through the consultancy request form available on the website.
His goal was very specific:
To develop a range of boilies with controlled solubility capable of satisfying two distinct categories of anglers:
* Anglers fishing short sessions without prebaiting (“fast bait” fishing)
* Anglers wanting to create a strong food area without overfeeding or satiating the fish
More specifically, the target audience included:
* River anglers prebaiting heavily the evening before fishing
* Quarry anglers managing large baiting campaigns
* Anglers fishing extended 4–7 day sessions abroad
The idea was to create a bait capable of maintaining feeding activity and food interest over time without excessively filling the fish up.
Industrial Production Constraints
Naturally, all of this had to be adapted to the realities of industrial production.
This means considering:
* Mixing methods
* Extrusion systems
* Rolling machinery
* Cooking procedures
* Production time
* Storage logistics
* Precise budget limitations
I want to clarify this because, although this article can inspire home bait makers, reproducing exactly the same result at home would require adapting the process to completely different quantities and equipment.
Honestly, if someone wants this exact bait, the easiest solution is simply to contact Boiliesroom directly.
The Fundamental Rules of Industrial Bait Design
When working on a commercial bait project, several points must always remain clear from the beginning:
* Optimisation of materials and costs
* Minimal waste
* Precise budget management
* Clear market positioning
* Efficient industrial processing
* Reduced production time
* Simple and coherent product communication
In industrial bait production, time is money.
And most costs come from labour and storage rather than raw materials themselves.
Choosing the Structural Base
The first step was selecting a bulk ingredient capable of covering around 40% of the final mix while remaining practical from a warehouse and supply perspective.
In this type of project, ready-made birdfoods are often the smartest solution.
A good birdfood already contains many useful ingredients such as:
* Soya
* Wheat
* Vegetable proteins
* Maize derivatives
* Bakery by-products
* Semi-finished cereal products
This dramatically simplifies stock management because the ingredients arrive already packaged, certified and stable with medium-to-long shelf life.
The “Quick” Boilie Range
The project developed into a line of four boilies called:
Quick Boilies
All four versions were based on the same structural mix, differentiated by around 15% of specific characteristic ingredients.
The four variants were:
* Fruit meals and fruity palatants
* Fishmeals and liquid foods
* Spice blends
* Peanut meal and peanut butter
This approach offers enormous production advantages.
In practical terms, the operator simply prepares:
* The birdfood base
* The technical mechanical ingredients
* The specific flavouring section
Everything is then mixed directly inside the industrial mixer before adding the liquid package and extruding through the auger system.
Egg-Free Production
One of the most important decisions was producing the bait without eggs.
This was done to achieve:
* Extreme but controlled solubility
* Easier drying
* Simpler preservation
* Better industrial consistency
Egg is one of the most problematic ingredients when dealing with storage and preservation on a large scale.
Of course, home bait makers could still include 1–3 eggs per kg if they wanted a slower and more structured breakdown.
The Mechanical Balance
The entire project relied on achieving a precise mechanical balance between:
* Native starches
* Modified starches
* Vegetable proteins
* Technical binders
The structural section of the mix became absolutely fundamental.
These additives are explained in detail in the technical additives chapter of my book [Boilies by The Bait Guru](https://www.thebaitguru.it?utm_source=chatgpt.com).
The products used are commonly employed in the food industry to:
* Thicken
* Bind
* Stabilise
* Create texture
In this specific project, the main tools were:
* Gluten
* Natural starches
* Enzymatically modified starches
* Pre-cooked cereal flours
* Vegetable proteins
* Dextrin
* Gum arabic
The goal was creating a soft and porous boilie while eliminating the annoying outer crust typically associated with cheap starch-heavy baits.
Prototype Development
I have to say that Marco’s experience — gained from producing hundreds of tons of boilies — was absolutely crucial.
In only four prototype productions, we managed to achieve the perfect balance.
The final result was extremely precise:
A 20mm boilie completely dissolved in:
* 5–6 hours in still water above 24°C
* 3–4 hours under river current stress
Exactly the target we had planned during the design phase.
Four Different Flavours, Same Behaviour
One of the most interesting aspects of the project was maintaining identical mechanical behaviour across all four flavours.
In other words:
* Same dissolution time
* Same breakdown speed
* Same structural response
while still offering completely different taste profiles.
The base price per kilogram remained identical across all four versions, although customisation obviously changes the final cost.
Customisation Possibilities
Because this is a rolling service project, anglers can customise:
* Attraction package
* Liquid flavours
* Soluble additives
* Hookbait strength
* Matching hookbaits
This is what makes the concept truly interesting.
You are not simply buying a generic ready-made boilie.
You are building *your own bait* on top of an already developed and technically optimised mechanical platform.
The Liquid Package
The standard liquid package relied mainly on:
* Glycol
* Sugary gels
* Malt syrup
* Fructose syrup
* Glucose syrup
These ingredients plasticise the dough and create the correct texture while still leaving enough room for additional attraction packages.
My Personal Version
For example, I had Marco produce 20kg of the fishmeal version for a close friend using:
* 100ml Aminol
* NHDC sweetener
* Cherry flavouring with a very acidic pH
This setup was designed specifically for the lakes in my local area.
I also strongly recommend the nut version enhanced with:
* Peanut butter
* Butyric acid
* Black pepper essential oil
Or alternatively, all four versions boosted with fermented fish sauce.
Naturally, all customisations must be agreed directly with the manufacturer according to ingredient costs and production quantities.
I am completely unrelated to the company’s commercial pricing and therefore cannot comment on detailed costs.
In my book you can find detailed explanations of all the technical ingredients used in modern boilie design.
