We all know that carrageenan is an ingredient, which is significantly used in the thickening of food products, especially dairy and meat products. However, for that it is important that the carrageenan is precisely processed and produced.
Below are the three different methods of production of carrageenan:
- Semi-refined carrageenan
- cottoniior E. spinosumare mainly used in executing this process. In this method, first the sorting of raw weeds is done and then people get rid ofcrude impurities present on weeds by their hands. After that, washing of weeds takes place to remove the salt and sand present on them. After washing, to increase the gel strength, hot alkaliis used for cooking them.If we talk about E. spinosumit dissolves quite readily which is why a much milder cooking cycle isexercised.The final product that we get through this process is semi-refined carrageenan. Semi-refined carrageenan is safe and you can use it as required.
- Refined carrageenan
The main difference between this method and semi-refined method is that in this process,first the carrageenandissolving and filtering takes place to take offcell wall debris.After doing this, either isopropanol or potassium chlorideis used for the precipitation ofthe carrageenan from the clear solution.At the end of this process, we get the refined carrageenan as anabsolute product.
- Mixed Processing
This process is frequently used in South America and it is a hybrid technology. In this technology, seaweed is handledas in the semi-refined process, but here to hinderthe process of dissolution;alcohol or high salt levels are consumed.This method lets you process huge amount of seaweeds in less time. Carrageenan produced is absolutely safe to be used.
Therefore, the above-mentioned processes are the three different methods of production of carrageenan.
