Molecular weight measurement systems
Malvern Panalytical’s range of systems solve analytical challenges, and provides data for optimising products and processes, predicting how products will behave and improves productivity.
Sensory quality, shelf-life, process stability and quality control are important, requiring analytical solutions at many stages.
Malvern Panalytical has systems for rheology, particle size and shape, zeta potential and molecular weight measurement from R&D through formulation to production, quality control and packaging.
Dry food ingredients are often milled to a final size or engineered using processes such as spray drying.
Process particle sizing solutions for optimised milling
Malvern Panalytical offers laboratory and process particle sizing solutions to optimise milling, including Mastersizer and Insitec.
The company also provides Parsum and Insitec solutions for spray drying and Morphologi G3 for particle shape analysers to examine how particles pack.
Malvern Panalytical rheometers such as Kinexus are used to examine the rheological behaviour of particles in suspension, to aid formulation of stable products with optimised texture, mouth feel or viscosity.
Gel permeation chromatography is available through Malvern Panalytical’s GPC / SEC, which measures molecular weight and structure of food biopolymers to achieve gelling and thickening performance.
Laser diffraction techniques with Mastersizer and Insitec can avoid over-grinding materials and significant costs.
Rheological instruments for study of additives
Food additives may contain natural or artificial ingredients and include antioxidants, bulking agents, colour, flavour enhancers, emulsifiers, preservatives, stabilisers, thickeners, gelling agents and sweeteners.
Malvern Panalytical’s particle size, zeta potential, imaging and rheological instrumentation are used to study additives and their interaction with food ingredients.
Mastersizer / Zetasizer are ideal for characterising particle size and charge, while Kinexus monitors interactions in food and determines optimal additive concentrations.
In addition, the emulsion stabilisation of flavourings can be improved using Mastersizer, Zetasizer and Kinexus.
Visco-elastic properties for food processing can be customised using Kinexus.
Optimising the formulation of spreads
Spreads and sauces, such as mayonnaise, margarine and ketchup, are generally dispersions of an insoluble solid or liquid phase, most commonly in water.
Both spreads and sauces have complex rheological properties, and contain ingredients that must be formulated to produce a stable product with required sensory and nutritional properties.
Malvern Panalytical’s analytical instruments and application solutions can reduce formulation time, ensure formulation stability and verify product properties.
The instruments also optimise manufacturing conditions, monitor quality, ensure regulatory compliance and benchmark products.
Emulsion-based drink formulations
Formulation of any flavour or colour emulsion can be optimised by modifying at particle size and charge, which influences its appearance and stability in final use.
The structure of foams such as beer heads can be evaluated using rheology.
Mastersizer / Zetasizer and rheometry system Kinexus increase shelf-life through the optimisation of formulations. The instruments also aid understanding about how particle size may change over time, reducing sedimentation or creaming in the product.
Sugar crystals may be an issue in some flavourings and size analysis can detect outsize particles before a problem occurs.
Chocolate consistency, quality control, and cost-efficient production
Understanding, monitoring and controlling particle size and shape in chocolate production ensures a consistent, high-quality production, as well as managing the flow and rheological properties.
Malvern Panalytical’s analytical solutions for size, shape, and rheology improve the chocolate manufacturing process. The solutions are used to monitor the quality of incoming raw materials, optimise grinding, blending, conching and tempering processes.
The instruments improve product quality and performance, minimise process downtime, increase productivity and yields to ensure brand consistency.

Products and Services
Characterisation of Emulsion-Based Drink Formulations
The formulation of flavour or colour emulsion can be improved by analysing the particle size and charge as this will influence its appearance (cloudiness) and its stability in final use.
Managing the Flow and Rheological Properties of Chocolate
Chocolate taste and texture are important for the consumer, while the manufacturer requires product consistency, quality control and economical production to maintain brand reputation.
Material Characterisation Solutions for Dry Food Ingredients
Dry food ingredients are available in different forms, and are either milled to a final size or created to be a certain size using a process such as spray drying.
Material Characterisation Solutions for Food Additives
Food additives preserve flavour, enhance taste and appearance, as well as slow spoilage.
Optimising Coffee Taste Using Ground Particle Size Distribution Measurements
The particle size of coffee grounds affects its flavour. If the coffee grind is fine, a powerful espresso flavour may be produced as complex organic components within the bean are released during brewing.
Viscotek UV Detector
Viscotek UV detector can be used in combination with Viscotek TDAmax, which completes a tetra detector format.
Understanding Yield Stress Measurements
The yield stress characteristic is a property associated with numerous types of complex fluids, where the material does not flow unless the applied stress exceeds a certain value. This is evident in everyday tasks such as squeezing toothpaste from a tube or dispensing ketchup from a bottle.
Effects of Particle Zeta Potential, Shape, and Size on Suspension Rheology
From foods to ceramics, paints, and adhesives, many products are dispersions or suspensions of particles in a liquid medium.
