Membrane filtration in the food industry Membrane technology overview Clarification + yield increase Pre-concentration + de-ashing including water recovery Diafiltration Decalcified Membrane filtration is a separation process which separates a liquid into two streams by means of a semi‑permeable membrane. The two streams are referred to as retentate and permeate. By using membranes with different pore sizes, it is possible to separate specific components of protein and peptides Depending on the application in question, the specified components are either concentrated or removed/reduced.

Membrane filtration in the food industry Membrane filtration can basically be divided into four main technologies. Ultrafiltration (open) Ultrafiltration (tight) Ultrafiltration (UF) Ultrafiltration is a medium pressure-driven membrane filtration process. Ultrafiltration is based on a membrane with a mediumopen structure allowing most dissolved components and some non-dissolved components to pass, while larger components are rejected by the membrane. In the food industry UF is widely used for protein concentration like soy protein, egg-white, gelatine as well as for special food additives like...

Membrane filtration in the food industry / lltts SSaa Reverse osmosis (RO) Reverse osmosis is a high pressure-driven membrane filtration process which is based on a very dense membrane. In principle, only water passes through the membrane layer. In the food industry, reverse osmosis is normally used for the concentration of sugars (glucose), special food ingredients and mainly for water reclamation. Nanofiltration (NF) Nanofiltration is a medium to high pressure-driven membrane filtration process. Generally speaking, nanofiltration is another type of reverse osmosis where the membrane has a slightly...

Membrane filtration in the food industry Microfiltration unit Clarification Natural sugar treatment and hydrolysed starched based sugars Sugar sources as cane or beet sugar from natural base as well as dextrose/glucose from corn or wheat are clarified using ceramic microfiltration to remove solids, proteins and impurities. The advantage of the membrane solution is a full automated closed process compared to traditional filtering methods. By adding diafiltration water the yield can be increased to a maximum. Hydrolysed peptides Depending on raw material and extraction process ceramic microfiltration...

Membrane filtration in the food industry Pre-Concentration Ultrafiltration is mainly used as pre-concentration process step for proteins. As this process step applies a low pressure only combined with a small footprint due to modular plant design this solution supports better sustainability and lowers carbon footprint when production capacity needs to be expanded. By adding diafiltration water proteins can be washed increasing the clarity by passing impurities, ash or other unwanted side components out into the permeate. Gelatin Gelatin is a color and odorless food ingredient with water binding...

Membrane filtration in the food industry Hydrolysed peptides Depending on raw material, extraction process and ash content the nano-filtration process is used to concentrate peptides while passing mono-valent ions to the permeate side. With choosing the appropriate membrane the product quality can be adjusted to customers needs. Due to the wide range of experience in this market GEA is the right provider to develop these specialized applications. Egg white As membrane filtration is a physical concentration process that works under cold process conditions (compared to evaporation) such process...

Membrane filtration in the food industry Cold brewed coffee The special drink cold brewed coffee has lower oil content and less fouling ingredients so that reverse osmosis is the recommended concentration method. The cold concentration keeps the aroma while the product quality stays unchanged. Dextrose/glucose concentration As alternative to the standard thermal concentration process for sugar concentration reverse osmosis can be used instead. The plants in such applications are adjusted to the customers needs as each project is specific. Water recovery Better sustainability and protection of...
