German Institute of Food Technologies The division has its own research projects planned for 2013. The quality of food is determined by their structure. Therefore, an optimization of food structures leads an improvement of long-term quality of food. Based on test on structure generation and the interdependency with the quality of food the DIL tries to increase the shelf-life of products. When the Bio-Economy division was founded in 2012, it was accompanied by an extensive realignment and expansion of the research platforms. As a result, meat technology was removed from the Process Technology business division, the biotechnology focus was placed on enzyme and raw material
Slowly varying envelope approximation assumptions which are made need to be justified. For example, consider the electromagnetic wave equation: If k and "ω" are the wave number and angular frequency of the (characteristic) carrier wave for the signal "E"(r,"t"), the following representation is useful: where formula_3 denotes the real part of the quantity between brackets. In the "slowly varying envelope approximation" (SVEA) it is assumed that the complex amplitude "E"(r, "t") only varies slowly with r and "t". This inherently implies that "E"(r, "t") represents waves propagating forward, predominantly in the k direction. As a result of the slow variation of "E"(r, "t"), when
