INTERACTIVE PACKAGING AS PROTECTION AGAINST PHOTODEGRADATION OF THE COLOR OF PASTEURIZED, SLICED HAM

Interactive packaging using oxygen absorbers with concomitant developm ent of carbon dioxide and packaging material with low oxygen transmiss ion rate (OTR: 2 cm3 m2 24 h atm-3) has been found to completely elimi nate discoloration of pasteurized, sliced ham normally encountered as a result of photo-oxidation of nitric oxide pigments during the first 24 h of display in illuminated chill cabinets. Further this packaging procedure has been found to be superior to conventional vacuum-packagi ng (90% initial vacuum) with regard to overall sensory evaluation, and equal to vacuum-packaging with 99% initial vacuum and interactive pac kaging using oxygen absorber, respectively, with regard to both overal l sensory evaluation, and microbial load at the end of a storage perio d of 26 d.
