Health and Environment – Nutrition / Food technology

Nutrition is essential to human health. Fraunhofer scientists evaluate the physiological effectiveness of special foods and food supplements. They also develop new processing methods, for instance for low-fat meat products, and research new sources of nutrition, such as lupin seeds.

It will soon be possible to use smartphones to scan apples for pesticide.

A new app from Fraunhofer development engineers looks directly inside objects and displays specific constituents. It has numerous uses: For instance, apples can be scanned for pesticide residues. Applications will be added successively following the Wikipedia principle.

  • New smartphone app looks inside objects.
  • “HawkSpex® mobile” displays constituents.
  • Hardware accessories are not required for cameras.

Innovative monitoring and sterilization methods for ensuring microbiological safety in the production chain for fresh plant-based foods – SAFEFRESH

© Photo Fraunhofer IVV

The collaborative SAFEFRESH project has set out to develop innovative methods for the rapid detection and deactivation of pathogenic microorganisms on the surface of fresh and minimally processed plant-based foods (salads, melons, shoots) in industrial production processes. In combination these methods should allow customized treatment and they should increase the microbiological safety of the products.

Integrated Multi-Trophic Aquaculture (IMTA) for sustainable nutrition

Conventional aquaculture has the disadvantage of generating large amounts of sewage that must be purified at great expense. Such problems are reduced in the IMTA because several organisms from various trophic levels are used to decrease the load of nutrients and waste. The particulate nutrients of the fishes are taken up by filtering organisms and the dissolved nutrients are utilized by macroalgae. This technique improves water quality and generates additional products.

Multimodal sensory integration processes with regards to food and their packaging and presentation – MultiSense

The sensory analysis of staple and luxury foods is currently only performed in a relatively one-dimensional way with the focus on analysis of odor, taste, or texture. In daily life we seldom encounter unisensory sensations in isolation, rather we experience multisensory stimulation. For example, the smell of brewing coffee is usually accompanied by the sound of a coffee machine or the sight of the coffee packaging. It is therefore necessary to consider the various combinations of sensory stimuli associated with foods and their packaging and presentation form.

Preservation of wine – PreserveWine

For the preservation of liquid foodstuffs such as fruit juices or wine we are implementing pressure change technology in a continuous process and investigating the impact of the process parameters on various products. In the EU-funded project PreserveWine, pressure change technology is being investigated as an alternative to adding the preservative sulfur dioxide in various process steps of wine production and is being further developed in cooperation with the firm Edecto GmbH and other European partners.
