PEF transforms yeast processing, enhancing productivity, improving product quality, extending shelf life, reducing costs and increasing yields

PEF-processed yeast finds extensive applications in the food and beverage sector. Bakeries can benefit from improved dough fermentation and enhanced flavour development; breweries can use PEF-treated yeast for faster and more efficient beer fermentation, improving taste profiles and increasing production capacity. PEF can enhance the fermentation of wine, cider, and other alcoholic beverages. Shelf life can be increased with controlled low-temperature microbial inactivation.

Enhanced Productivity

Traditional fermentation time can be reduced, resulting in faster production cycles and higher output.

Increase yield

PEF optimises yeast extraction, resulting in increased yields.

Preservation of Nutritional Value

PEF is a low-temperature process that preserves more of the yeast's proteins, vitamins, minerals, and other bioactive compounds.

Extended shelf life

PEF treatment effectively inactivates spoilage-causing microorganisms increasing shelf life.

Energy Efficiency & Sustainability

PEF requires lower energy consumption compared to thermal treatments, fast fermentation time & improved yield minimise resource usage & waste.

Elea Pulsed Electric Field systems process at low temperatures with minimum energy usage, preserving greater nutritional value, reducing waste and lowering costs.

Find the right Elea PEF Advantage system for your yeast production line

We have installed more than 250 Elea PEF systems globally, working for some of the world’s leading food producers. Every Elea PEF Advantage systems share the same 24/7 production capability and are built to operate under extreme conditions.
PEF improves fermentation in yeast by applying precisely controlled electrical pulses, electroporating the cells, and releasing more of the intracellular contents such as enzymes, proteins and flavour compounds

Elea PEF Advantage extraction benefits for Yeast

PEF treatment optimises yeast extraction, improving yield and enhancing product quality. By applying precisely controlled electrical pulses, PEF gently opens yeast cells, releasing intracellular contents such as enzymes and flavour compounds. This promotes better fermentation and ultimately results in a superior end product with enhanced flavour, aroma, and nutritional profile.

Elea PEF Advantage inactivation

By subjecting yeast to PEF treatment, the spoilage-causing microorganisms can be efficiently controlled. PEF disrupts the cell membranes of undesirable microbes, inhibiting their growth and extending the shelf life of yeast-based products. This benefit is particularly valuable for bakeries, breweries, and other food industries where product freshness and longevity are crucial.
