Figure 6 Oxidation Stability Curves at different temperatures
According to the induction period of oxidation at different temperatures, the formula is
derived as follows: T=174.3-16.86 lnt
t: Induction time of oxidation, h
T: Target temperature
The shelf life of SN-180401 Saw palmetto oil is predicted to be 7011 hours or 292 days
at 25 C. That is to say, the shelf life of Saw palmetto oil can reach 292 days under the
condition of continuous fresh air at 25 C. It is possible to achieve 2-3 years shelf life
under the actual sealed and light-proof storage conditions.
