SPRAY CRYSTALLISED INGREDIENTS
RouxLux®
Integrated fat-and-starch or flour roux crystals developed for effective dispersion, reliable thickening and consistently smooth finished products.

CONTROLLED THICKENING SYSTEMS
Traditional roux functionality in a production-ready format
RouxLux® combines fat and flour or starch within a stable, spray-crystallised structure designed for food manufacturing and foodservice applications.
The integrated crystals disperse effectively into hot or boiling liquids, helping manufacturers produce smooth, creamy and lump-free results with consistent thickening performance.
With low-shear processing, good flow properties and the potential for later-stage addition, RouxLux® provides a practical alternative to preparing a traditional roux within the production process.
WHY ROUXLUX®?
Reliable thickening with simpler processing
RouxLux ® helps connect efficient preparation with the taste, texture and stability required from the finished product.

Effective dispersion
Designed to disperse effectively in hot or boiling liquids while reducing the risk of unwanted lump formation.

Consistent thickening
Supports effective utilisation of the starch component and repeatable viscosity development.

Smooth, neutral results
Produces a creamy, lump-free texture with a clean, neutral taste that allows the wider flavour profile to remain prominent.

Good flow and stability
Supports controlled flow, freeze-thaw performance and reduced syneresis across suitable sauces and prepared foods.
HOW RouxLux® WORKS
Integrated fat and starch, released when required
The spray-crystallised structure controls how the fat and starch are handled, dispersed and activated within the formulation.

01 - Integrate
Fat and starch are combined into uniform, free-flowing roux crystals designed for consistent measurement and handling.

02 - Disperse
When introduced into hot liquid, the crystals disperse effectively using only low-shear mixing.

03 - Thicken
The starch becomes available within the liquid system, developing the required viscosity and a smooth, creamy finished texture.
The resulting viscosity will depend on the selected RouxLux® grade, use level, liquid system, temperature and processing conditions.
APPLICATIONS
Versatile thickening across savoury and sweet products
RouxLux® systems can support food manufacturers, foodservice operators and catering producers across a broad range of liquid and prepared-food applications.
- Soups and sauces
- Ready meals
- Gravies, stews, and casseroles
- Pie fillings
- Foodservice and vending
- Sweet sauces and fillings
Supports smooth, consistent thickening in white sauces, dark sauces, cream-style sauces and prepared soups.
Provides controlled viscosity, flow and stability within chilled, frozen and ambient ready-meal components.
Helps create the required body, coating and eating quality while allowing the wider savoury flavour profile to remain prominent.
Supports controlled flow, filling stability and a consistent texture through production, storage and reheating.
A convenient route for applications requiring efficient preparation, low-shear mixing and repeatable results.
Selected systems can provide smooth thickening and controlled flow across dessert sauces, sweet fillings and related applications.
SELECTING THE RIGHT ROUXLUX® SYSTEM
Match the thickening system to the finished product
The most appropriate RouxLux® system depends on the required viscosity, process, storage conditions and finished-product character and declaration required.
Selection can take account of:
- White, cream-style, or dark sauce
- Soup, gravy, filling, or ready-meal application
- Required viscosity and flow
- Addition temperature and processing time
- Available mixing and cooking equipment
- Desired fat level and sensory character
- Chilled, frozen, or ambient storage
- Freeze-thaw and reheating requirements
- Ingredient-declaration objectives
- Gluten-free requirements
- Manufacturing or foodservice preparation route
Non -Gluten options based on rice, maize, or cornflour are available within the range, subject to grade selection and appropriate production controls. Selected systems using RSPO-certified palm- and Non Palm based fats are also available, subject to current specification confirmation.

PRODUCT DEVELOPMENT AND SUPPORT
From thickening requirement to production-ready system
Our technical and product-development teams can support RouxLux® projects from initial system selection through application trials, sensory evaluation and commercial scale-up.
1
Define the product brief
Establish the finished product, required viscosity, processing route, storage conditions and intended sensory character.
2
Select the development route
Choose the appropriate RouxLux® system against the required colour, flavour, flow, stability and declaration requirements.
3
Develop and evaluate
Create and refine samples while assessing dispersion, viscosity development, smoothness, flavour, flow, syneresis and reheating performance.
4
Prepare for production
Finalise the formulation, use level, addition stage, processing requirements and validation plan before progressing towards commercial scale.
Bring us your product format, process and required finished viscosity.

APPLICATION GUIDANCE
Consistent thickening starts with the complete formulation
RouxLux® performance will be influenced by the wider recipe, processing conditions and the product’s journey through storage, reheating and serving.
Technical recommendations may consider:
- Appropriate RouxLux system
- Typical starting use level
- Required finished viscosity
- Liquid composition and solids level
- Addition stage and temperature
- Mixing and heating conditions
- Holding time before filling
- Chilling, freezing, and thawing
- Reheating and serving conditions
- Ingredients, allergen, and gluten-free declarations
- Sensory and shelf-life validation
Use levels and performance should be confirmed through application-specific trials using the intended production and storage conditions.
