High-energy monochromatic radiation (laser, high performance LED) in the area of UV/VIS/NIR: Effect on (bio-) chemical systems and reactions in the living tissue of fruit and vegetables. (e.g. suppression of browning and decay; influence on synthesis of phytochemicals)
Project
Project code: MRI-OG-08-17
Contract period: 01.01.2009
- 31.12.2015
Purpose of research: Applied research
The living plant tissue of fruit and vegetables contains a variety of receptor systems for light (natural sunlight). They serve on the one hand for the energy input, on the other hand, they are starting point in the plant for the control of an immense variety of biochemical processes. Man uses this for example for artificial influencing of the plant growth in greenhouses. Till now mainly polychromatic light is applied in the UV-VIS area. Narrower light bands are produced by use of filters, which goes at the expense of energy. Due to the rapid development in the area of semiconductors it is possible today to produce monochromatic light of very high energy (diode laser, high performance LED). The complete area from ultraviolet to infrared is covered meanwhile. The institute OG posesses such monochromatic light sources meanwhile. It is intended 'to adress' quite specifically and with high energy certain receptor systems. One aim is the influencing of the polyphenol oxidase system for the suppression of the browning in 'fresh cuts.' Another aim is the synthesis apparatus for secondary plant substances (polyphenols, vitamins…e.g. during storage under controlled atmospheres, CA)
