These Types of Seaweed Loaded with Health and Beauty Benefit

Seaweed is one of the biological resources found in coastal and marine areas. The term “seaweed” is botanically ambiguous because it is used for 2 different groups of “plants”.

This seafood ingredient is famous for its unique taste and texture. Seaweed is safe for consumption because of its nutritional content which is good for health.

Biologically, seaweed is a group of plants with chlorophyll consisting of one or many cells and in the form of colonies. Seaweed contains organic materials such as polysaccharides, hormones, vitamins, minerals, and also bioactive compounds. Various types of seaweed such as Griffithsia, Ulva, Enteromorphna, Gracilaria, Euchema and Kappaphycus have been widely known as food sources such as seaweed salad or a potential source of carrageenan needed for the gel industry. Likewise with Sargassum, Chlorela/Nannochloropsis which have been used as heavy metal adsorbents

Seaweed has the ability of chromatic adaptation, namely the adjustment of the proportion of pigments with various received lighting qualities so that they can produce various colors of the thallus/tree. There are several types of red seaweed that have economic value and have been cultivated in various countries

Red seaweed is famous as a producer of carrageenan. Carrageenan is a polysaccharide compound that has the ability to form gels with better strength. There are three types of carrageenan, namely kappa, iota, and lambda carrageenan. Currently, seaweed as raw material for making carrageenan is met from cultivation

Type of Seaweed

Types of seaweed that are widely cultivated as raw material for carrageenan are E. cottonii and E. spiosum. The two types of seaweed are most often cultivated because the demand is very large, both domestically and abroad. In addition, the types of carrageenan-producing grasses are E. edule and Hypnea. However, the demand for both types of grass is relatively low so it has not been cultivated.

Eucheuma cottonii

This type of seaweed is the most widely cultivated carrageenan producer in Indonesia. E.cottonii has smooth thallus cylindrical, cartilaginous, green, yellow, gray, or red in color. In the thallus there are spines that are not arranged in a circle.

Branches of E. cottonii spread in various directions with the main stems coming out close to each other at the base.

Eucheuma spinosum

E. spinosum in some areas known as agar-agar fractures. The thallus of this seaweed is smooth, cylindrical, cartilaginous, dark brown, yellow green, or red purple. In the thallus there are thorns that grow in circles at varying intervals to form thallus segments between the thorn circles.

Sargassum sp

This species of seaweed can grow up to 12 meters. The main characteristics of Sargassum sp. is a cylindrical or flattened thallus shape. If held, this seaweed feels slippery. There is a main stem with a slightly rough round shape.

Sargassum has thick branches like trees on land. The shape of the leaves is wide, oval, and looks like a sword. The color of the Sargassum thallus is brown. Sargassum can be found on rocks in choppy areas.

Hypnoea sp.

This seaweed belongs to the red seaweed or Rhodophyta. Characteristics that can be recognized from Hypnea sp. is the straight thallus. Hypnea has weak branches and is brown or green in color. Along the talus can be seen there are fine hairs. This type of seaweed is commonly used for its carrageenan part as industrial raw material.

Eucheuma cottonii

Just like Hypnea, Eucheuma cottonii is also a group of red seaweed aka Rhodophyta. E. cottonii has a branched thallus with a cylindrical or flattened shape. These ramifications when viewed more closely are irregular and rough.

This seaweed habitat is in tidal areas, coral reef flats, or attached to hard substrates. In Indonesia, the cultivation of E. cottonii is found in South Sulawesi, Central Sulawesi, Southeast Sulawesi, East Nusa Tenggara, West Nusa Tenggara, Bali, and East Java.

Eucheuma spinosum

This type of seaweed can be recognized by its cylindrical thallus. The branches are pointed and full of protrusions in the form of soft spines. The surface of E. spinosum is smooth, the color is dark brown, dark green, yellow green, to purplish red.
