EXTRACTION PROCESS OF ACTIVE INGREDIENTS FROM THE ALGA ASCOPHYLLUM NODOSUM

摘要

The extraction process of active ingredients from the alga Ascophyllum nodosum comprises the following steps in succession: - obtaining a homogeneous product through the micronisation of a quantity of fresh or dried Ascophyllum nodosum alga - detaching the active ingredients from the fibres by treating said homogeneous product in an ultrasonic bath at a controlled pH at a value of less than 6 for the microbiological stabilisation of the said homogeneous product - eliminating the fibres through a first product filtration process removing the proteins from the product for its physical stabilisation eliminating odorous and/or oily substances through a second product filtration process - sterilising the product in order to obtain a stable aqueous extract through a third filtration process.
