What is Kappa-Carrageenan?
The compound found in red seaweed is commonly used as a food additive. Karagenan is a carbohydrate that can be used to thicken and stabilize food and as a replacement for fat in some products. When extracting from seaweed, they form a gel that can be used to improve the structure of different foods. Kappa-Carrageenan is one of the three types of carragenan used as a food additive and tends to form the strictest gels. The sulphate part of the molecule concerns the sulfur molecules that are bound to sugars. Long sugar molecules turn into a spiral and form a gel. Three types of carragenan - Kappa, Iota and Lamdba - differ mainly in the number and location of their ester sulphate groups, which affect the temperature at which they dissolve in the liquid and how firmly the gel.
The source of this composition is red algae, with different types of seaweed containing different types of carragenan. Kappapaphycus alvarezia contains only the type Kappa. chondrus crispus , With Kappa-Carrageenan, it is most commonly originated from k. Alvarezia and Eucheuma cotton , also called kappapaphycus cotton .
Most foods containing kappa-cargeenan are dairy products. Only a small amount is added in the dairy, but usually less than 0.5 percent. If more is added, the milk will start to solidify. This additive prevents fat and protein distribution into layers and helps to create a consistent texture. Kappa is usually added to the whipped cream to maintain consistent air and lightness.
Removal of fat from meat products can produce dry taste and undesirable texture, so low-fat meat contains kappa-carrageenan to restore tenderness and juiciness. Like half of the fat in the rolls, it can be replaced by this food ingredient without adversely affecting the taste. It is also added to poultry products to avoid being lostYou water during the cooking process.
In many cases, Kappa-Carrageen can be used as a substitute for gelatin and pectin. Kappa versions are mainly used in calories without calories or with low calorie content. The combination of three different types of carragenane creates jelly that does not melt at high temperatures, which is very useful for hot climate. It is also a good substitute for gelatin for people after a vegetarian or vegan diet.
Kappa-Carrageenan is also used in a number of food products. For example, it is the main ingredient found in the air freshener. Perfume, water, ingredients and potassium salts are mixed together and formed to match the refreshment container. When the holder is open, the gel slowly releases the smell into the room.
There are two different methods to remove this carbohydrate from seaweed: by removing everything else from the seaweed, but only to carogenhane and extracting only carogenhan of seaweed. Originally Karagenan was extracted into a liquid solution thatHe was then dried until only carbohydrate remained. The second method uses basic solutions with high pH to dissolve all other compounds, but carbohydrate. The second method is usually much faster and cheaper.
