Notes:
Mechanical deaeration in a vacuum closing machine and flame deaeration achieved comparable results in removing noncondensible gases from low-liquid packs of canned green beans and apple slices. Residual headspace oxygen was calculated from experimental measurements of pressure, void volume, and percent oxygen. Prolonged (〉 5 set) exposure of hot filled samples to mechanical vacuum prior to seaming did not result in lower residual oxygen. Sample changes through 9 mo storage were not influenced by deaeration method; consequently, residual oxygen or vacuum in cooled samples immediately after sampling may be used to assess adequacy of air removal.
