Abstract
The invention relates to process for converting berry and/or fruit materials to fractions comprising bioactive compounds, said process comprising the steps, where at least one berry material or fruit material selected from berries, fruits, by-products, side streams and waste materials originating from berries or fruits, and any combinations thereof is sieved whereby a seed fraction is separated from a skin fraction, the seed fraction is subjected to sanding and a seed coat fraction comprising surface layer of the seeds and a sanded seed fraction comprising the sanded seeds are obtained.
Claims14
A process for converting berry and/or fruit materials to fractions comprising bioactive compounds with antimicrobial activity, wherein the process comprises the steps,
- sieving at least one berry material or fruit material selected from berries, fruits, by-products, side streams and waste materials originating from berries or fruits, and any combinations thereof, having water content not more than 15 wt %, whereby a seed fraction is separated from a skin fraction,
- sanding the seed fraction, whereby a seed coat fraction comprising 2-40 wt % of said surface layer of the seeds and a sanded seed fraction comprising the sanded seeds are obtained, and
- extracting bioactive compounds with antimicrobial activity from the seed coat fraction comprising the 2-40 wt % of said surface layer, wherein the berries are selected from the group consisting of the genus Rubus, Sorbus, Rosa, Empetrum, Aronia and Hippophae and combinations thereof, and the fruit are selected from the group consisting of the genus Vitis, Punica, Pyrus and Malus, and combinations thereof.
