Aran is…
Molecular Oxygen Plasma or what we call
Polyatomic Oxygen Polymer - “POP” called
AranTM
Oxygen commonly exists as an O2
molecule. The AranizerTM creates, through
energy, higher allotropes of oxygen, O4,
O5, O6, O8… These oxygen molecules
have oxidizing properties far greater than
ozone and a much longer half-life. Thus we
have a powerful oxidizer.
Reaction
5 molecules of aran
to one molecule of
mycotoxin will be
enough aran to
theoretically
breakdown the
Aflatoxin B1
Theoretical Formulation
5O5 + C17H12O6 
CO2 (vapor) + H2O (vapor)
Basic theoretical formula
Tested Agent
 7-18-05 AJ-1
Aflatoxin B1 Aspergillus flavus mycotoxin
 Chemical Formula C17H12O6 Formula Weight 312.3
The Aflatoxin B1 compound was bought from Sigma Aldrich
Company. It is a standard reagent grade mycotoxin, catalog #
A6636 neat powder.

Why
 Common Health Problem – “listing was revised to known to
be human carcinogens in the Sixth Annual Report on Carcinogens in
1991.” National Toxicology Program, Department of Health and
Human Services
This is your

Occurrence in foods
cereals, oilseeds, spices and tree nuts, maize, groundnuts (peanuts), pistachios, brazils,
chilies, black pepper, dried fruit and figs, milk, nonfat dry milk, cheese, yogurt, peanut
butter, eggs, meat, and just about any other food substance that is grown in warm
moist climates

Still on WHY
 Chemical Formula - C17H12O6 important because this has
benzene ring and bonds that are in many other compounds that the
allotropic oxygen can breakdown such as solvents, formaldehyde, and
other biological agents.
Aflatoxin B1 History
 Aflatoxins were first identified in England in 1960’s the shorthand of its
causative agent: A. fla.10,000 turkeys and ducks died within a few months called Turkey X disease
Cause - Aspergillus flavus contamination of peanut meal
Previous to this:
Khrushchev in 1939 was faced with horses dying on farms all over
the western parts of the Ukraine. Khrushchev wrote, ‘‘I can’t
believe that science is absolutely helpless here…” ‘‘We had won more
than just a victory for our agriculture. It was a moral and political victory
as well. But how many collective farm chairmen, cattle raisers,
agronomists, animal husbandry specialists, and scientists had lost their
heads as saboteurs before I stepped in and took charge of the
situation.’’
Korneev (1948) fed white mice with oats infested with Stachybotrys
alternans strains
According to Gajdusek (1953), cases of human stachybotryotoxicosis
have been found mainly in regions where the equine disease has also
been reported.
Forgacs et al. (1958) studied the toxicity of 40 strains

The final setup is:
an unknown
portion of
Aflatoxin B1
placed in a clean
(sterile) 250 mL
Erlenmeyer flask.
A 100 mL aliquot
of distilled water
was added to the
Erlenmeyer flask.

Equipment Data
 AJ-1 Aranizer output 2525 mg/hr Aran gas average
molecular weight of O6 previous similar models
tested by Campbell and Associates
 Spectrophotometer 2401 Schimadzu UVProbe
190 nm – 900 nm peak analyses peaking below 190 nm
- O4 peaks at 151 nm
 PK Laboratory Analyzed the series of samples and
blanks using HPLC
Sampling
 2 - Blanks taken from the dilution water not treated
 1 aliquot of dilution water was Aranized for comparison
 2 - 10 mL aliquots were taken from the original test matrix – labeled
“Start Point”
 NOTE the Aflatoxin did not dissolve well– therefore the sampling was
done while the sample was being stirred to ensure well mixed
samples
 After 30 minutes 1 – 10 mL
 After another 30 minutes 1 – 10 mL sample was taken labeled 60
minutes
 After another 11 hours 1 – 10 mL sample was taken labeled 12 hours
