Starter cultures are literally on everyone’s lips. The helpful micro-organisms are employed in the most diverse fields of the food industry and also as a probiotic dietary supplement. Examples are the dairy, meat and bakery industries, in the production of fermented vegetables, in the production of wine and beer and in the animal feed industry. Starter cultures are cultivated from undefined, empirically produced species to attain a predictable and reproducible quality and quantity of the product.
The production of starter cultures can be divided into two sections. After cultivation in fermenters, the bacteria must be processed and separated from the fermentation solution. This consists of the nurtured lactobacilli and the remainder of the nutrient solution including the produced lactic acid. Firstly, the micro-organisms are separated and concentrated from the liquid phase. Nozzle and self-cleaning disc separators in steam-sterilized design are available for this step of the process. The concentrated lactobacilli then pass to a freeze-drier. Finally, the cultures are packaged under oxygen exclusion and stored at low temperatures. This retains their activity for months before they are processed, e. g. as “live cultures” in probiotic yogurts.
The careful treatment of the living micro-organisms, sterility and a high separation efficiency are prerequisite to the economical, reliable and efficient processing. The separators from GEA employed in this production process are therefore equipped with hydrohermetic product feed systems which minimize the shear forces when the product enters the bowl and therefore guarantee the high vitality of the cells.

Aseptic valves face exceptionally high demands within UltraClean and Aseptic processes. You can be assured that they all provide highest quality in terms of hygienic design and sustainability.
GEA separators are designed for liquid-based applications. Using centrifugal force, they are used for separating suspensions consisting of two or more phases of different densities, i.e. they can be used for liquid-liquid separation, for liquid-liquid-solid separation or for liquid-solid separation. They are equally as effective at separating liq...

Waste reduction is important to us at GEA, and by harnessing the power of freeze drying technology, we can transform surplus food into valuable, long-lasting products – helping to reduce waste, extend shelf life and build a more resilient food supply for generations to come.
When plant-forward South Korean food producer Pulmuone brought GEA the challenge of developing a modern spin on the traditional chewy cold (naengmyeon) noodle, GEA’s R&D experts were up to the challenge. They helped develop what is now a commercial hit produced with less water and electricity than previously existing methods. The result is also true to the traditional origins of the dish as well as Pulmuone’s health, well-being and sustainability roots.
