Extracting process of carrageen from its raw material

The main resource of carrageenan was first found on the subtidal Irish moss beds in the cold-water Maritime Provinces of Canada in the year of 1970. At this starting period, it’s about 65000 wet tons of carrageenan raw material was collected from there. Now currently about 35000 wet tons of carrageenan was collected from that water bed.

Nowadays the huge requirements and problems with supplying of carrageenan will be led to the invention of aquaculture industry for other warm-water carrageenan-producers, like Eucheuma and Kappaphycus.

The artificial method for growing the carrageenan was originated in the country of Philippines as a simple process of tying vegetative fragments of the plants onto monolines which are strong nylon lines that are attached to the stakes or rafts and the producers permit it to grow for several weeks of time.

When the producers feel that the carrageenan is grown completely, they will harvest and send it to the drying process. Normally a red alga is totipotent, so that small fragments of its pieces will grow into an entirely new plant which is an idea behind the producers of carrageen who get lots of profit with carrageenan growth.

The process of extracting the carrageenan from its raw materials is started with a drying process. The collected carrageenan materials are dried by spreading and air-drying or by using rotary dryers. When it was completely dried then it was sent to the huge factories was the actual process with a carrageenan was started.

In factories, the boiling process of carrageenan was taken place, after that some harmless chemicals and acids are added to the carrageen. When it completely mingled with the chemicals, it was filtered and then the milling process is taking place to make it as a fine-grained powder which is used in the food.
