Malvern Panalytical Molecular Weight Measurement Systems

Characterisation technologies

Malvern Panalytical provides food processing companies with a range of high-quality characterisation tools that are used to optimise product performance through a thorough understanding of materials.

The company’s highly trained staff have expertise in research and development (R&D), materials handling, and testing methodologies, with a thorough understanding of the requirements of large-scale food manufacturing. In addition, the instruments provide a clear indication of the exact ingredients for labelling applications.

Malvern Panalytical is a global company, with sites in North America, Europe, and China. It has strong customer service, helping companies develop expert analytical solutions that deliver superior, actionable insight.

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.

About Malvern Panalytical

Panalytical was formed by a merger between businesses Malvern Instruments, PANalytical, ASD, and Claisse in January 2017.

The company employs more than 2,000 highly trained staff, which are experts in research and development (R&D) and manufacturing. Malvern Panalytical is a global company, with sites in North America, Europe, and China. It has strong customer service, helping companies develop expert analytical solutions.

White Papers

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.

Products and Services

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 for Compositional Analysis

Viscotek UV detector can be used in combination with Viscotek TDAmax, which completes a tetra detector format.

Zetasizer AT Nanoparticle Characterisation System

Malvern's Zetasizer AT brings the industry-leading dynamic light scattering (DLS) technology of the Zetasizer Nano to the process development and manufacturing arena, enabling real-time monitoring of nanoscale particle processes online.

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.
