The present study aimed to evaluate two different processes of olive oil aromatization with Schinus terebinthifolius Raddi, conventional maceration (CM) and ultrasound-assisted maceration (UM), and their influence on quality parameters, total phenolic compounds (TPC), fatty acid profile (FA), volatile organic compounds (VOCs), antioxidant capacity, and oxidative stability. Flavoring reduced peroxide values, although it increased free fatty acids and extinction coefficients. The flavorization process did not change the FA profile, which showed oleic acid as a major compound. The VOCs varied and the migration of oxygenated monoterpenes were more effective in UM-flavored olive oil compared to its CM counterpart. All flavored olive oils presented higher oxidative stability than the control samples and UM-flavored olive oil was highlighted for its higher antioxidant activity. These findings proved that aromatization with pink pepper assisted by ultrasound may be an alternative to improve olive oil quality and create a new competitive flavored product.
本研究旨在评估两种不同的用巴西胡椒(Schinus terebinthifolius Raddi)对橄榄油进行增香的工艺,即传统浸渍法(CM)和超声辅助浸渍法(UM),以及它们对品质参数、总酚化合物(TPC)、脂肪酸谱(FA)、挥发性有机化合物(VOCs)、抗氧化能力和氧化稳定性的影响。增香降低了过氧化值,尽管它增加了游离脂肪酸和消光系数。增香过程并未改变脂肪酸谱,其中油酸为主要成分。挥发性有机化合物有所不同,与传统浸渍法增香的橄榄油相比,超声辅助浸渍法增香的橄榄油中氧化单萜的迁移更有效。所有增香橄榄油的氧化稳定性均高于对照样品,超声辅助浸渍法增香的橄榄油因其较高的抗氧化活性而备受关注。这些发现证明,超声辅助用粉红胡椒增香可能是提高橄榄油品质并创造一种新的具有竞争力的风味产品的一种替代方法。
