Lipophilic extracts of Viburnum opulus (VOP) and Hippophae rhamnoides (SBP) berry pomace recovered by supercritical CO (SFE-CO) were analysed by UPLC-Q-TOF-MS and GC × GC-TOF for their triacylglycerol, tocopherol, phytosterol and fatty acid composition, while oxidative stability was evaluated by Oxipres and Rancimat methods. SFE-CO recovered 16.99% and 26.24% of lipids from SBP and VOP, respectively. Linoleic, linolenic, oleic, palmitic and palmitoleic acids were major in SBP oil, while VOP oil was composed of almost equal amounts of linoleic and oleic acids. Therefore, remarkably higher diversity of triacylglycerols was identified in SBP. The content of β-sitosterol and α-tocopherol was 359.5-514.5 and 65.38-118.6 mg/100 g, respectively. Hydrocarbons were other quantitatively important lipophilic components, including health beneficial squalene. All extracts improved oxidative stability of mayonnaise. The extracts of berry processing by-products by green extraction method contain valuable bioactive constituents and could be of high interest for applications in functional foods and nutraceuticals.
用超临界 CO2(SFE-CO2)从欧洲雪球果(VOP)和沙棘(SBP)浆果渣中提取的亲脂性提取物,通过 UPLC-Q-TOF-MS 和 GC×GC-TOF 进行了三酰基甘油、生育酚、植物甾醇和脂肪酸组成的分析,而氧化稳定性则通过 Oxipres 和 Rancimat 方法进行了评估。SFE-CO2 分别从 SBP 和 VOP 中回收了 16.99%和 26.24%的脂质。亚油酸、亚麻酸、油酸、棕榈酸和棕榈油酸是 SBP 油中的主要脂肪酸,而 VOP 油中则几乎等量地含有亚油酸和油酸。因此,SBP 中的三酰基甘油种类明显更多。β-谷甾醇和α-生育酚的含量分别为 359.5-514.5 和 65.38-118.6mg/100g。烃类是其他重要的亲脂性成分,包括具有健康益处的角鲨烯。所有提取物都提高了蛋黄酱的氧化稳定性。绿色提取方法从浆果加工副产物中提取的提取物含有有价值的生物活性成分,可能对功能性食品和营养保健品的应用具有很高的兴趣。
