Fig. 6. Influence of different factors on shelf life of orange juice packaged in monolayer PET bottles. OS = oxygen scavenger, AL = aluminium-foil seal in
the screw-cap, LN = liquid nitrogen, R = bottles stored at 4 C, A = bottles stored at 25 C. Number from 1 to 8 are the different treatments being 1:
OS + AL; 2: OS; 3: OS + AL + LN; 4: OS + LN; 5: AL; 6: only monolayer PET; 7: AL + LN; 8: LN.
