Researchers in the Netherlands have investigated the molecular structure of plant proteins that must provide alternatives for the animal proteins in our food over the next 10 years. They discovered that proteins with a similar chemical structure behaved differently after heating. The behaviour of the proteins after heating plays an important role in the development of a new type of meat substitute product.
Francesca O’Kane used various proteins from peas and soya for her research. After heating the plant proteins formed a gel from which she could deduce the structure of the proteins after heating. Although the pea protein legumin has a structure which is very similar to the soya protein glycinin, O’Kane discovered clear differences between the two proteins after heating. The gel of the soya protein could be repeatedly heated without the gel losing its strength or flexibility. This was not possible with the pea protein gel, due to its unusual spatial structure. Upon repeated heating this gel became increasingly stiff.
The greatest stumbling block in the design of foodstuffs using non-animal proteins is the unpredictability of the final product’s structure, the so-called texture. O’Kane used several proteins from peas to map the behaviour of plant proteins. She followed the molecular structure of the proteins in three stages: the unfolding during heating, the aggregation after heating and the eventual formation of a network, in which the proteins formed a gel. The formation of the gel provides a model for how proteins aggregate.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
