We also sought to evaluate the efficacy of mango and acerola pulps as antioxidants in film-forming dispersions using a response surface methodology design experiment. The bio-based films were used to pack palm oil (maintained for 45 days of storage) under accelerated oxidation conditions (63% relative humidity and 30 C) to simulate a storage experiment. The total carotenoid, total polyphenol, and vitamin Ccontents of films were evaluated, while the total carotenoid, peroxide index, conjugated diene, and hexanal content of the packaged product (palm oil) were also monitored. The same analysis also evaluated palm oil packed in films without antioxidant additives (C1), palm oil packed in low-density polyethylene films (C2), and palm oil with no package (C3) as a control. Although the filmforming procedure affected the antioxidant compounds, the results indicated that antioxidants were effective additives for protecting the packaged product. A lower peroxide index (36.12%), which was significantly different from that of the control (p < 0.05), was detected in products packed in film formulations containing high concentration of additives. However, it was found that the high content of vitamin C in acerola pulp acted as a prooxidant agent, which suggests that the use of rich vitamin C pulps should be avoided as additives for films.Submitted by JURANDI DE SOUZA SILVA (jssufba@hotmail.com) on 2012-03-07T18:36:57Z No. of bitstreams: 1 __ieeexplore.ieee.org_ie...mber=5582140&isnumber=5708787.pdf: 327580 bytes, checksum: 45fd96a95628b0f1375a726092d5f929 (MD5)Made available in DSpace on 2012-03-07T18:36:57Z (GMT).
