Extracts

As versatile as extracts are, as diverse are the possible applications of membrane technology in the extract sector:

Whether concentrating, fractionating or sterilizing extracts, there is almost no limit to the specific membrane selection and ideal process conditions for the respective application.

Microfiltration is applied in extract clarification and sterilization, for example with the help of ceramic membranes.

Ultrafiltration and Nanofiltration are widely used for macro-molecule concentration, fractionation, de-salting and small molecule concentration.

Reverse osmosis for concentration of extracts at moderate temperature. For all these applications, the membranes used can be spiral wound modules on polymeric basis.

MMS has many years of experience and know-how in all fields of extracts:
