Oral Processing of Food

Ensuring love at first bite

The increasing demand for healthier and more convenient foods, agriculture-based products, and new varieties of food products requires an intense evaluation of the sensory attributes of food. Will consumers like the texture of a product with reduced fat content? How does the food feel in my mouth? Is it easy to chew? What impact will it have on consumers' swallowing behavior?

Rheology is used to measure the interrelations between composition and structure of food which determines such attributes. It also measures changes in food properties that arise during manufacturing, transportation and storage.

Research and development rheometers like the Thermo Scientific™ HAAKE™ MARS™ platform allow you to measure a wide range of attributes through flexible instrument configurations including the combination of two different analytical methods. Combining rheology with optical systems such as microscopy or spectroscopy offers the advantage of being able to understand changes in physical properties and structure at the same time.

For instance, optical methods are used to observe the crystalline structures of starch or fat crystallization behavior which impact sensory properties as well as storage ability. Accessories like the tribology cell allow the study of friction on interacting surfaces. Breaking tools are available to enable texture analysis, and accessories for interfacial measurements deliver insights into the stability of interfacial surfaces.

The next “best-selling” food product

When it comes to the formulation of a new food product, food engineers have to keep in mind the lifetime of a food product. It starts with the variety of food ingredients and their origin. Then comes the design of an efficient production process involving various steps such as mixing, pumping, cooking, filling and storage behavior. That is followed by end-use application settings such as spreading, scooping or storage behavior, and finally the sensory perception of consumers which includes mouthfeel and swallowing quality.

Learn how rheological properties such as viscosity, yield stress, time and temperature dependent, or elongation behavior are linked to processing and sensory behavior. With Thermo Scientific rheometers, you have efficient tools at hand to investigate your next food products.
