Measure the texture of cereal products
Discover how a Texture Analyser can be used to measure the textural properties of various cereal products in a variety of ways.

Why measure the texture of cereals?
The measurement of texture in cereal products serves as a critical tool for scientifically assessing and optimising the quality, consumer appeal, and manufacturing processes of these staple food items.
Texture analysis provides quantifiable data that aids in evaluating attributes like crispness, crunchiness, chewiness, and firmness, allowing for a comprehensive understanding of cereal product properties. This analytical approach not only enables the fine-tuning of product formulations and processing methods but also contributes to enhancing the overall sensory experience for consumers.
Consequently, the scientific measurement of texture in cereal products from raw ingredients to finished processed products plays a pivotal role in advancing both product development and quality assurance within the food industry.






How can a Texture Analyser be applied to cereal texture measurement?
Cereal products, encompassing breakfast cereals, cereal bars, and related grain-based foods, possess distinct textural attributes that influence consumer preferences. Utilising a Texture Analyser in their manufacture and development provides essential insights:
- New product development: Texture Analysers support R&D efforts when launching new cereal variants, ensuring they meet targeted textural profiles.
- Optimising formulations/reformulations: As ingredients or their ratios are adjusted or recipes are altered, for instance, to reduce sugar, salt, or fat, it's vital to understand how these changes affect texture. As demand for whole grain, high fibre, or protein-enhanced cereals grows, understanding the textural implications of these formulations is also crucial.
- New ingredient assessment: When introducing a new ingredient, it's vital to understand its impact on the overall texture of the cereal. The Texture Analyser can quantify these changes.
- Milk interaction: For breakfast cereals, understanding how they interact with milk or other liquids in terms of textural changes (like sogginess) is pivotal for product positioning.
- Shelf life studies: Over time, cereals can become stale or change in texture. Regular texture analysis during shelf life studies can help determine when these changes occur and help in formulating to extend the product's life.
- Optimising processing conditions: Different processing methods (extrusion, baking, puffing, etc.) can alter the texture of the cereal product. By using a Texture Analyser, manufacturers can optimise these conditions to achieve the desired texture.
- Quality assurance and control: To maintain consistent quality, routine texture testing is vital. This ensures every batch of cereal or cereal product aligns with the brand's standards, solidifying consumer loyalty.
- Consumer preference testing: Along with taste tests, understanding texture preferences can be crucial. By correlating consumer feedback with objective texture analysis data, manufacturers can develop products that better cater to consumer preferences.
- Packaging influences: Packaging can affect the texture of cereals, especially concerning moisture migration. Texture analysis can inform packaging decisions to maintain product integrity.
- Competitor benchmarking: By analysing the texture of competitor products, companies can understand where their product stands in the market and if there are texture gaps they might want to fill.
- Product claim validation: If a cereal product is marketed with specific texture claims like "crunchy clusters" or "soft-filled centres," texture analysis provides empirical evidence to support these claims.
Typical measurements
A Texture Analyser can measure various textural properties of cereal products, depending on the type of product and its intended use.
Here are the key texture properties that can be measured:
Firmness
Rice (according to ISO standard 11747)
Hardness
For denser cereal products or bars, determining the force required to bite through or break the product is crucial.
Springiness (or elasticity)
This evaluates how cereal products, especially those with a more chewy texture like certain cereal bars, recover their shape after deformation.
Adhesiveness/stickiness
Some cereal products like granola clusters may have a degree of stickiness, especially those with added sweeteners or binders, and this measures the work needed to pull the product away from a surface. Rice, oatmeal and couscous all possess this property.
Tensile strength
For products like cereal bars, understanding the resistance to a force trying to pull it apart is important for ensuring they don't crumble easily.
Stress relaxation behaviour
Kernels
Compressive strength (increase/decrease)
Grains, breakfast cereals, extrudates, cereal bars, oats, rice
Gel strength
Gel strength determines the ability of a e.g. starch gel to resist deformation or fragmentation under applied forces, providing crucial insights into its texture, firmness, and stability where starch gels are used as thickeners, stabilisers, or gelling agents.
Crispness/crunchiness
Especially relevant for breakfast cereals and certain snack items, this measures the force and sound associated with the fracturing of the product.
Brittleness/fracturability
The force at which the cereal product fractures. This can be critical for products that are meant to have a light and brittle texture or a particular snap or break.
Cohesiveness
Measures how well the internal structure of the product holds together during deformation, which can impact mouthfeel and chewiness.
Bowl life
For breakfast cereals, understanding how they change texture when milk or another liquid is added can be crucial. This can measure how quickly a cereal becomes soggy and loses its crispness.
Yield strength
Kernels
Consistency
Porridge, baby food, rice pudding
Rupture force
Measuring the yield strength of cereal kernels involves subjecting individual kernels to mechanical forces to determine the point at which they undergo permanent deformation or fracture.
Ensuring the right texture in cereal products is vital for product success, as texture plays a significant role in consumer preference. A Texture Analyser allows for objective, repeatable measurements of these properties, helping manufacturers ensure product consistency and optimise formulations and processing.

Using the Texture Analyser for new cereal ingredient and product ideas
The food and cereal industry had been evolving rapidly with increasing consumer demand for healthier, sustainable, and more diverse products.
Here are some of the newer ingredient and product ideas in cereal product research, development, and production and a typical academic reference to show how the Texture Analyser has already being applied:
Alternative grains and seeds
This includes ancient grains such as quinoa, chia, teff, amaranth, and millet. They're prized for their nutrition and diverse textures.
Functional ingredients
Superfoods, probiotics, prebiotics, adaptogens, vitamins, and minerals. Ingredients such as turmeric, ginger, and various berries are also being added for health benefits.
Sustainability
Development of new cereal food products with reduced environmental impact, such as using grains that would have been discarded as by-products but are instead reused, and utilising sustainable ingredients like seaweeds or algae.
Customisable and personalised cereals
Brands offering customisable blends based on personal preferences or dietary needs.
Protein-enriched cereals
Incorporating plant-based proteins, like from legumes, soy, or peas, and even insect-based protein.
Sugar alternatives
With the increasing demand for reduced sugar products, alternatives such as stevia, monk fruit, and erythritol are being explored.
Allergen-free and free-from cereals
Gluten-free, nut-free, dairy-free options, etc. to cater to those with dietary restrictions or allergies.
Texture innovation
Combining different grains, freeze-dried fruits, and other ingredients to create varied texture experiences in cereals.
