摘要:

榛子是我国重要的经济林树种, 其坚果中含有丰富的不饱和脂肪酸, 被称为“心脏健康”食品。本文介绍了榛坚果中油脂含量及脂肪酸组成, 分析了影响油脂含量及脂肪酸组成的潜在因素, 综述了榛仁中酚类、生育酚和植物甾醇等主要生物活性成分的研究进展,简单陈述了作为榛坚果加工副产物的蛋白质的相关情况,并探讨了加工对榛子油的影响。通过文献分析发现:生长环境及品种的差异均会影响榛子油脂肪酸的品质, 榛子油富含的亚油酸使其在加工储藏中容易发生氧化酸败。生育酚及植物甾醇是油脂的主要活性物质, 其中α-生育酚及β-谷甾醇含量最为丰富, 是延缓油脂氧化的主要活性成分。此外, 以没食子酸、丁香酸、香草酸、缩合单宁等为主的酚类物质主要分布在果皮中, 且不同品种间存在显著差异。未来, 榛子油的研究可从“使用新兴技术”和“协同抑制油脂氧化”等方向展开。

Abstract:

Hazelnut (Corylus), as an important non-wood forest trees in China, is renowned for its abundant unsaturated fatty acids and recognized as a "heart-healthy" food. This paper introduces the oil content and fatty acid composition of hazelnuts, analyzes the potential factors that affect these properties. The research progress on phenolic compounds, tocopherols and phytosterols in hazelnut kernels was reviewed. The protein produced as a by-product of hazelnut processing was briefly introduced, and the impact of processing on hazelnut oil was discussed. Literature analysis suggests that the oil content and fatty acid composition in hazelnuts are influenced by variations in growing environments and cultivars. The high content of linoleic acid in hazelnut oil is the primary cause of its susceptibility to oxidative rancidity during processing and storage. Tocopherols and phytosterols have been identified as the main active compounds naturally existed in hazelnut oil, with α-tocopherol and β-sitosterol being the most abundant. These compounds play a crucial role in preventing oil oxidation. Furthermore, phenolics such as gallic acid, syringic acid, vanillic acid and condensed tannin are primarily concentrated in the hazelnut skin, displaying significant variations among different hazelnut varieties. Future research should explore the application of emerging technologies and the synergistic application of active antioxidant ingredients in hazelnut oil.

Key words: hazelnut, unsaturated fatty acids, oxidation, tocopherols, sterols
