Storage conditions for fortified oil samples.

Model	Storage condition
A	Samples in 20 ml transparent bottles exposed to usual artificial light for 9 hours a day with filling level of 50%, stored at the room temperature (27 ± 3°C)
B	Samples in 20 ml transparent bottles exposed to usual artificial light for 9 hours a day with filling level of 100%, stored at the room temperature (27 ± 3°C)
C	Samples in 20 ml dark-brown bottles with filling level of 50%, stored at the room temperature (27 ± 3°C)
D	Samples in 20 ml dark-brown bottles with filling level of 100%, stored at the room temperature (27 ± 3°C)
E	Samples in 20 ml transparent bottles with filling level of 50%, stored at the refrigerator (4 ± 1°C)
F	Samples in 20 ml transparent bottles with filling level of 100%, stored at the refrigerator (4 ± 1°C)
