Накратко на български
Разработва се нов уред за измерване на вискоеластичността на течности и твърди храни, като например капсули с течно съдържание. Той позволява по-лесен анализ на свойствата на материалите с минимално количество проби и без нужда от сложно оборудване.

Final Activity and Management Report Summary - RHEO (Development of a novel instrument for viscoelastic characterisation of food and biological materials)
The objective of this research proposal was to develop a novel rheological instrument that can be used for small amplitude viscoelastic characterisation of liquids, solids, and semi-solid materials. In this research project, development of a novel measurement system for small amplitude viscoelastic properties of materials is proposed. It is estimated that the proposed method is suitable for measurements up to 10 KHz and requires sample in micro litre amounts. In addition to fluid samples, this instrument is suitable for rheological characterisation of solid food samples such as liquid filled capsules and irregularly shaped grains. Another important advantage of the proposed instrument is its ability to be used as an attachment to commonly available instruments such as texture analyser (Surrey, United Kingdom) and Instron universal testing machine (Norwood, United States). This property of the proposed instrument allows texture analysers to conduct small amplitude viscoelastic testing without any requirements such as air bearing and compressed air that are usually required by conventional rheological instruments. Construction and successful validation of the proposed instrument can provide a powerful analytical tool which can be used for research or quality control purposes by researchers from many different disciplines.

Цел на проекта
The purpose of this study is to develop a new oscillatory squeezing flow instrument for viscoelastic characterization of materials, ranging from very soft biological polymer networks to irregularly shaped solid materials like corn grains. This relatively low-cost and easy-to-use instrument will be suitable to be used as an attachment for commonly available instruments such as the Texture Analyser and Universal Testing Machine, and will make these instruments suitable for frequency sweep type viscoelastic measurements.The dynamic mass of the instrument will be extremely low compared to the conventional instruments, allowing it to reach relatively higher frequencies with very high sensitivity. The proposed method will be tested by using important representative samples from many different scientific disciplines, such as food science, biology, pharmacy, and chemistry.The instrument will be operating with random frequency excitation and will be able to produce large amounts of data in a very short time. In order to validate the results obtained at high frequencies (>100 Hz), the microrheological technique called Diffusing Wave Spectroscopy will be used, and low-frequency data will be validated with a conventional rotational rheometer. This proposal outlines the setup details and working principles of the proposed instrument and the research methodology to validate it.
