Abstract
The present invention relates to a composition of seaweed algal extracts having a dry matter content between 18-36%. These extracts preferably belong to Ascophyllum nodosum. The said extracts are also characterised using bioactive compounds found in them inherently. The present invention also provides a method of making the said composition and characterising the same.
Claims18
A seaweed algal extract comprising a percent dry matter between about 18%-36% by weight, wherein, relative to fresh weight, the algal extract has:
- fucoidans at 6-15 g per kg;
- glycine betaine at 8-47 mg per kg;
- laminine at 208-438 mg per kg;
- and mannitol at 30-60 g per kg.
A composition comprising an algal extract of Ascophyllum nodosum having a percent dry matter between about 18%-36% by weight and a biostimulating agent or plant-protecting composition, where the plant protecting composition comprises an herbicide, fungicide, insecticide or pesticide, and, wherein, relative to fresh weight, the algal extract has:
- fucoidans at 6-15 g per kg;
- glycine betaine at 8-47 mg per kg;
- laminine at 208-438 mg per kg;
- and mannitol at 30-60 g per kg.
A composition comprising an algal extract of Ascophyllum nodosum having a percent dry matter between about 18%-36% and a super absorbent polymer, wherein, relative to fresh weight, the algal extract has:
- fucoidans at 6-15 g per kg;
- glycine betaine at 8-47 mg per kg;
- laminine at 208-438 mg per kg;
- and mannitol at 30-60 g per kg.
A process for preparation of an algal extract, said process consisting of:
- a. feeding an initial algal extract comprising dry matter between 3-8% by weight to an evaporator heat exchanger;
- b. passing steam through the heat exchanger, transferring heat to the initial algal extract, generating in the heat exchanger an algal extract and sediment;
- and
- c. decanting from the heat exchanger the algal extract produced in step b and removing sediment produced therefrom to produce the algal extract;
- and, wherein the algal extract has a percent dry matter between about 18%-36% by weight;
- wherein the algal extract has less than 1% alginic acid;
- wherein, relative to fresh weight, the algal extract has:
- fucoidans at 6-15 g per kg;
- glycine betaine at 8-47 mg per kg;
- laminine at 208-438 mg per kg;
- and mannitol at 30-60 g per kg.
