powder The encapsulated gac oil powders (10 g) were vacuum-packed and non-vacuum-packed into high barrier vacuum pouches(Caspak Products Pty Ltd, Melbourne, Vic, Australia). The packed samples were then stored at different temperatures of −20◦C, 10◦C and room temperature (RT, 25–30◦C) for 360 days, at 40◦C for 120 days and at 63◦C for 28 days. For storage at RT, the samples were also packed into laminated and non-laminated vacuum pouches in the presence or absence of air. For practical reasons, due to the time consuming nature of the testing of storage conditions at 40◦C or lower, the simple accelerated method of using oven storage at 63◦C (Schaal Oven test) was carried out as is often done to evaluate the stability of food products containing oils. Duplicate samples were periodically withdrawn during the storage in order to measure surface oil content, peroxide value (PV), carotenoid (-carotene and lycopene) content and colour.
