Cultivated by the Aztecs 8,000 years ago, Amaranth is sometimes referred to as a “pseudo-cereal”.

Compounds of Interest Applications

Squalene

Beta-tocopherol (and other tocopherols)

Alpha-spinasterol

Sitosterol

Tocopherols:

  • Antiradical and antioxidant
  • Decrease cardiovascular disease
  • Decrease cancer risk
  • Decrease age-related macular degeneration

Sterols: Decrease serum cholesterol levels

Specifically:

  • Squalene:
    • Cosmetics: moisturizer
    • Pharmaceutics: increases immune efficiency, decreases serum cholesterol levels, antitumour effects, antioxidant
Why SFE

SFE allows for fractionation for less free fatty acids

SFE allows retention of thermolabile compounds

Optimization

5,192 psi/40˚ C

Addition of cosolvent (ethanol) increases yield of squalene and tocopherols

Lower pressures (2175psi) increases yield of squalene

Grinding of particles increases yield of tocopherols.
