Technical challenges
Technical challenges for aerosol nanosalt include:
• Keeping particles to 500nm without them clumping
together again
• Valve clogging
• Particles becoming enlarged due to hygroscopicity
• Product instability due to the effects of moisture
• Supermarket shelf life
• Even distribution on popcorn
(We still can’t solve this. Sorry…)
Human health
How table salt affects our lives in three questions:
1. Does sodium have an essential function in the human body?
Yes! Present in the bloodstream, sodium is one of three elements
that maintain the ideal amount of water in cells so as to
not overload the circulating system. Therefore, maintenance of
an ideal blood pressure is also a function of sodium, provided
that consumption is not excessive. This function is called
water/electrolyte balance. In addition, sodium is essential for
muscle contraction and the transmission of nerve impulses.
2. Should table salt be prohibited from our diet?
No! The ideal amount to consume is 5g of salt per day (2g of sodium
daily, according to the World Health Organization, 2013).
However, it is very easy to exceed this. In Brazil, consumption is
about 12g per day.
3. What’s happens if one exceeds the maximum level of
sodium day after day?
Too much sodium can increase blood volume and consequently,
the effort of the heart to circulate all of this extra blood will
result in an increase of blood pressure (hypertension), one of
the major risk factors for heart disease.
Technical conclusions
The reduction of table salt particle size to the nanometric level,
along with the use of an aerosol dispenser’s two exclusive mechanisms
of partition (mechanical and thermodynamic), affords
an optimal way to dispense nanosalt. This will help to reduce
the daily intake of salt by adding it to food at only 5–20% of the
usual 10g /day, without losing any of the good, salty taste. This
can mean the consumption of 10g /month instead of 10g /day.
The body retains less fluid, resulting in lower blood pressure
(less water in blood plasma).
The final message is that an aerosol dispensing system can
help save lives and, in terms of public health, can also serve as
a preventative, helping to decrease salt consumption and keep
people healthier.
