Got Algae?
Algae
What do these
items all have in
common?
Algae
They are all made of seaweed!
Seaweeds are large marine
algae that grow on the coastal
waters of many countries.
Algae
• They include thousands of species from microscopic organisms called phytoplankton to huge floating/anchored organisms commonly seen washed up on shore. Scientists now classify these algae as protists.
Algae
• Many kinds of seaweed are edible and rich in vitamins and iodine. Asian
cultures use seaweed like green beans and carrots
are used in the United States.
Algae
• Algae contains great nutritional value and are used in many cultures to wrap vegetables, rice, or
raw fish (sushi).• You can obtain algae to
eat from a health or ethnic food store. They
may include nori, kombu, kelp, and dulse.
Algae
• Americans have not developed a taste for
seaweed, so manufacturers use
derivatives from seaweed instead.
Seaweed derivatives include:
alginatescarrageenan
beta carotene
alginate
carrageenan
beta carotene
Algae
• These derivatives act as stabilizers,
thickeners, and colorants in the foods Americans
eat today.
Algae
• The three main groups of
seaweeds are brown, red, and
green algae. Each provides important
ingredients for manufacturing
foods.
Algae
• Alginates come from brown algae. They make water-
based products thicker, creamier, and more stable
over extreme differences in
temperature, pH, and time.
Algae
• Some products containing
alginates are brownie mix,
whipped topping, relishes, salad
dressings, sauces, and gravies.
Algae
• Carrageenan is extracted from
certain types of red algae. It is used in
stabilizing and gelling foods cosmetics,
pharmaceuticals, an industrial products.
Algae
• Some products containing
carrageenan are chocolate milk, coffee creamer,
yogurt, ice cream, pudding,
toothpaste, and sour cream.
Algae
• Beta carotene is a natural coloring
pigment derived from green algae. It is used as a yellow-
orange food coloring and may help
prevent certain types of cancers
Algae
• Some products made with beta carotene are
multiple vitamins, cheese, egg
substitute, ice cream, margarine,
mayonnaise, whipped topping.
Algae
• The many products listed here are only a small portion of
the many products derived from seaweed.
• This is another reason to protect Earth’s oceans!
