Large yellow croaker roe phospholipids (LYCPLs) have various functions and high nutritional value, which are expected to be functional foods ingredients. The aim of this study is to investigate the oxidative stability of LYCPLs at different temperatures (100 °C, 140 °C and 180 °C) in terms of peroxide value (POV), thiobarbituric acid-reactive substances value (TBARS), acid value (AV) and fatty acids compositions of phospholipids. The volatile compounds were also identified and analyzed via headspace solid-phase microextraction-gas chromatography-mass spectroscopy (HS-SPME-GC-MS) and headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS). The results showed that the highest POV was 192.92, 133.70 and 121.25 meq/kg at 100 °C, 140 °C and 180 °C within 10-20 min, respectively, then fell along with the increment of heating time, while the highest TBARS was 6.38, 7.66 and 8.19 mg/kg at 30 min, respectively. The AV was increased, but monounsaturated fatty acid and polyunsaturated fatty acid content were decreased with the increment of temperatures. A total of 94 volatile compounds were identified, and the content of alkanes, aldehydes, and heterocyclic compounds were reasonably increased, while the aromatic compound and amide compound content were decreased when LYCPLs heated at 180 °C. The present research improves the comprehensive understanding of oxidative stability of marine phospholipids.
大黄鱼鱼卵磷脂(LYCPLs)具有多种功能和高营养价值,有望成为功能性食品的成分。本研究旨在从过氧化物值(POV)、硫代巴比妥酸反应物质值(TBARS)、酸值(AV)和磷脂脂肪酸组成等方面研究 LYCPLs 在不同温度(100°C、140°C 和 180°C)下的氧化稳定性。还通过顶空固相微萃取-气相色谱-质谱联用(HS-SPME-GC-MS)和顶空气相色谱-离子迁移谱联用(HS-GC-IMS)对挥发性化合物进行了鉴定和分析。结果表明,在 10-20min 内,100°C、140°C 和 180°C 下的最高 POV 分别为 192.92、133.70 和 121.25meq/kg,随后随着加热时间的增加而下降,而最高 TBARS 分别为 30min 时的 6.38、7.66 和 8.19mg/kg。AV 增加,但随着温度的升高,单不饱和脂肪酸和多不饱和脂肪酸含量减少。共鉴定出 94 种挥发性化合物,当 LYCPLs 在 180°C 下加热时,烷烃、醛和杂环化合物的含量合理增加,而芳香族化合物和酰胺化合物的含量减少。本研究提高了对海洋磷脂氧化稳定性的综合认识。
