Notes:
Some naturally occurring and synthetic phenolic antioxidants have been evaluated in a dry model system simulating the exposure of lipids in freeze-dried membranes of whole tissue foods. The system is a linoleic acid monolayer on activated silica gel autoxidized at 80°C in dry air. The system is dry and porous and the demonstrated monolayer adsorption and restricted translational mobility of the lipid present a plausible model of freeze-dried membrane characteristics. Although relative effectiveness of the common antioxidants in this system has some similarities to the reported order in other dry systems, there are notable exceptions. For example, butylated hydroxyanisole is by far the most effective antioxidant in the silica system whereas it is reported to be much less effective than propyl gallate in bulk oils and some other dry systems. Thus, special conditions appear to modify antioxidant effectiveness in the lipid monolayer on silica.
