PEF SCHOOL PROGRAMME

This year we have expanded the school progamme to include most innovative up to date range of PEF topics.

History of PEF

Familiarity with the history of PEF helps us to understand PEF today. This lecture opens the door on to this amazing world.

Basic Principles of Electroporation

Pulsed electric energy is one of the most successful methods to open living cells in vitro. This lecture describes the factors controlling electro-permeabilization of cells. The effect of the different electrical parameters will be outlined.

PEF Equipment Design

Various applications of PEF, spanning from basic research to industry, demand for different high voltage pulse generation concepts. During this lecture, you will be able to observe the different pulse generator concepts and basic designs of treatment chambers.

Food Applications (Drying/Freeze-drying, Extraction, Freezing, Snack production)

This lecture will introduce you the effects of electroporation on different plant tissues (roots, fruits, vegetables, herbs, etc.). At the same time, it will describe the most interesting applications of PEF in the food industry such as “cold” extraction, fast freezing, improved drying, etc.

Microbial Inactivation

This topic presents you a possibility to see and understand another application of PEF as non-thermal method for inactivating microorganisms in liquid foods. Particular attention will be devoted to the proposed microbial inactivation mechanisms and its influencing parameters.

Stability of Nutrients (Shelf-life Extension)

During this lecture, you will realise that beside microbial inactivation, PEF can also retain the health-related compounds, and greatly extend the product shelf-life. Moreover, you will see new opportunities, quality and value for juices and smoothies after PEF treatment.

Industrial Applications

This theme will open you the secret door to the PEF industrial world. The recent industrial implementation as well as industrial opportunities for PEF technologies will be presented.

Medical Applications

PEF can be used not only for food and non-food treatment but as well for the medical application. The lecture will present you how PEF can intensify the chemotherapy treatment and how it can help to save the humans live.

Life Cycle Assessment Study

Practical system thinking of PEF application. Learn to consider negative and positive aspects of PEF technology application in the domain of sustainability (costs and incomes, nutrition and health, resources and emissions).

Practical Pilot Plant Workshops

The practical courses aim to provide hands-on experience on major topics relevant for PEF applications. We will offer three different laboratory workshops: Microbial inactivation; plant cell electro-disintegration; pulse generation and equipment design.

Excursion to Industrial Partners

Theoretical knowledge and hands-on experiences in pilot plant scale are just the beginning. As a round up, you will be able to see operating industrial PEF systems at our local industry partners. This will allow you to get insights into industrial dimensions.

PRACTICAL COURSES

Attend one day of practical insight and gain hands-on experience in Pulsed Electric Field technology at Elea's custom build pilot halls as well as in DIL's diverse technology labs in Quakenbrück.

Juice extraction

Focus of this course is the analysis of yield increase by PEF treatment. PEF is able to perforate the cell membrane and as a consequence the extraction of liquid or valuable compounds is increased. Within this course, apple juice will be produced and the influence of PEF as well as different pressing methods will be studied.

Snacks Production

Applying PEF prior to French fries and chips processing results in lots of quality and economic benefits throughout the whole production process. This course will give new insights and practical background information regarding the process, raw material, product development and improvement of the whole downstream process.

Cell disintegration index

During this practical course, you will perform the PEF treatment of solid plant raw materials. Subsequently, you will fulfil the effect of PEF on different plant tissues and will be able to quantify its cell disintegration index. Moreover, you will observe and evaluate the impact of PEF on following processes, such as drying, extraction, cutting, peeling, etc.

Shockwave

Shockwave or hydrodynamic pressure processing is application of high pressure produced by electrical discharge under water in fractions of milliseconds. The shockwave propagates through the water high-energy and any objects that are an acoustical match with water. As foods such as meat, fruits or vegetables are composed mostly out of water, the pressure crosses the product and creates a mechanical stress that disrupt the structure. The participant will be able to see a continuous prototype for shockwave treatment and a demonstration on several different food products.

Microbial Inactivation

Usually a thermal pasteurization is used to extend the shelf life of fresh juices. This treatment provides the required microbial safety, but it also has negative effects on the quality of the product in terms of taste and nutritional value. Within this workshop, the participants will prepare fresh juices, such as strawberry smoothie or green vegetable juice, and treat it by PEF. Samples will be taken and stored for a comparison with thermal treated sample.

Life cycle assessment study

The course is aimed to develop practical system thinking skills (in application to PEF), which will be helpful in the consideration of the new processing technologies development and implementation. Participants will learn to consider negative and positive aspects of PEF technology application in the domain of sustainability (costs and incomes, nutrition and health, resources and emissions). System thinking skills will be tested in practice for PEF equipment construction (DIL workshop), and LEGO based modelling for the use phase (potato processing example).

After hours

After the lectures and practical courses you have the opportunity to network and relax in sociable atmosphere.

The first PEF school day will end with a welcome evening, snacks and a tour around the University of Applied Sciences Osnabrück.

During the PEF school, the ‘Maiwoche‘ takes place in Osnabrück. This city festival invites to have a good time with music, street food and more.

Night watchman tour

We will organize a night watchman tour in beautiful Osnabrück city at May 15th.

When in 1913 the last night watchman made his rounds through the city, ended a nearly 250 years old tradition. The so-called auxiliary police sergeant not only ensured peace and order on the nocturnal streets, but he should also intervene in case of fire danger and “unauthorized manure pile”. Equipped with small lanterns, the orderkeeper leads you through the night to present you Osnabrück in a very special glow – by candlelight.

Dinner

On Thursday 17th will be a dinner. More info coming soon.
