What is the economic importance of alga?

Answer:

Economic Importance!!!!

Brown algae are not only important to the
environment but also in the human world. We use the seaweeds commercially for
food, cosmetics, pharmaceuticals and in the sciences. The most important part of
brown algae is algin, a starch-like chemical that is found in the cell walls of
kelp. It is used as a stabilizer and emulsifier in making dairy products,
prevents frosting and pies from drying out in the baking industry, a thickener
in pharmaceutical and chemical and manufacturing industries, such as making
toothpaste, shampoo, and a myriad of other products, used in making rubber
products, paper, paints, and cosmetics, and it thickens printing paste which
makes sharper print in the textile industry
