Abstract Details

2015, Master of Science, Ohio State University, Food Science and Technology.
This study explored the potential of selected food additives to extend the shelf life of seed butter made with sesame, sunflower and pumpkin seeds. The results showed that grape seed extract is potent as an antimicrobial agent against Salmonella enterica and Listeria innocua in the seed butter. Cinnamaldehyde was also able to reduce S. enterica but L. innocua in the seed butter. To maintain the texture and to prevent oil separation in the seed butter, hydrogenated rapeseed oil (HRO) was found to prevent excessive hardness and effectively control the oil separation of the seed butter during the storage time in this study. On the other hand, palm kernel oil (PKO) was weak in preventing excessive hardness, and it did not prevent oil separation in the seed butter. This showed that HRO was a more efficient stabilizer than PKO in the seed butter. This study also reported the antioxidant effect of a-tocopherol in the seed butter. The results showed that by adding a-tocopherol to the seed butter oil above the level of its natural background concentration did not effectively inhibit or delay lipid oxidation.
