8. New Ways of FOOD PROCESSING…

Story1: Pulsed electric fields (PEF)

PEF is based on electroporation and is suitable for use in broad range of food and bio-process applications Short treatment times: microseconds Total PEF process time: seconds. Low energy levels PEF produces the electroporation in bacterial, plant and animal cells.

BENEFITS FOR POTATO PROCESSORS

LESS HEAT

LOW ENERGY USE REDUCED BLANCHING TIME LESS BROWNING

LESS OIL UPTAKE LESS FRACTURE

New amazing shapes are great with Elea PEF.

Control: No PEF treatment

Heat treatment: 90°C-20 seconds

PEF 2-6; Heat treatment

The lowest intensity PEF treatment increased the shelf life from 1 week (untreated) to more than 2 weeks. More intense PEF treatments can increase the shelf life up to 60 days under cold storage (4°C).

Story 2: Shockwave Treatment Hydrodynamic technique

SHOCKWAVE Hydrodynamic High Pressure

High pressure levels but at µs timescale

• For meat breeds (Limousin, Charolais, Galloway etc.) up to 20 % of the cuts are suitable as steak meat

• For dairy breeds (Holstein etc.) these cuts sum up to max. 10 %

• To improve the quality of beef meat often an aging is applied

Due to changing consumer requirements there is a need to improve beef meat quality, to achieve higher amount of steak cuts

Conclusion It´s all about values! Healthy and attractive Food for a healthy society and a healthy planet = People – Planet – Profit More data flow along the value chain will increase transparency Understanding the consumers preferences is key! Food processing and food product development has to think out of the box.
