Spirulina

  • By Heather L. Milliken

2
What is Spirulina?
  • It is a blue-green algae
  • One-celled form
  • 65-71 percent protein
  • Contains all essential amino acids
  • Spirulina has an 8-10 percent photosynthetic
    conversion rate (land plants have about a 3
    percent conversion rate)

3
The First Harvesting Techniques
  • Kanembu make Dihé cakes (2)

4
Harvesting
  • In Mexico, Spirulina was found to be harvested
    and dried for consumption up until the late 16th
    century
  • The Spanish Conquest led to lakes being drained
    to make room for new civilization (2)

5
Techniques Continued
  • Studies have been performed to maximize the
    production of Spirulina.
  • This is done by monitoring the floatation and by
    determining the most productive growth stage. (1)

6
The Benefits of Harvesting Spirulina
  • Spirulina can be cultivated in shallow ponds
  • As a result of this, Spirulina can double its
    biomass every 2 to 5 days, yields can produce
    over 20 times more protein than soybeans on the
    same area, and 40 times that of corn and 400
    times that of beef. (2)

7
Nutritional Value
  • Spirulina is a food source that consists of more
    than 60 protein.
  • It has the highest known source of beta carotene.
    (25 times more than raw carrots)
  • Spirulina has more vitamin B12 than any other
    known source.
  • It contains the richest food source of gamma
    linolenic acid (GLA). (GLA is the precursor to
    body's important hormone prostaglandin)
  • Spirulina is richest source of chlorophyll.
  • Spirulina has a number of natural antioxidants
    like beta-carotene, vitamin E, vitamin B1, B5,
    B6, zinc, manganese, copper and selenium amino
    acid methionine. (3)

8
The Pink Flamingo
  • Some flamingos evolved a filter in its beak to
    specifically eat spirulina.

Forms of Consumption
  • Kanembu people use crumbled Dihé to mixed with a
    sauce of tomatoes and peppers, and poured over
    millet, beans, fish or meat.
  • It taken in the pill form as a nutritional
    suppliment
  • Spirulina is added to numerous types of pet
    foods.

10
The Benefits of Eating Spirulina
  • Reduces blood cholestrol
  • Spirulina helps to control diabetes
  • Helps in kidney detoxification
  • Useful in combating malnutrition
  • Spirulina is very useful in preventing vitamin A
    deficiency (helps prevent blindness and eye
    disease (4))
  • Aids in the prevention of anaemia
