摘要: 硬壳蛤(Mercenaria mercenaria)因其个大壳厚使得热加工开壳时间长易造成品质改变。超高压开壳技术能较好地保留产品的色泽和香气,但会产生大量的超高压开壳处理液。为了有效利用该处理液,以硬壳蛤水煮开壳处理液冻干粉(MFPS)为对照,分析不同超高压压力(200、250、300 MPa,6 min)开壳处理液冻干粉(MFP1、MFP2、MFP3)的风味特征变化。结果表明:四组冻干粉风味差异明显,其中对照组MFPS的挥发性风味物质种类与含量明显低于MFP1、MFP2、MFP3三个组,但其蛋白质和脂肪含量、甜味、苦味和鲜味值都极显著高于其他三组(P<0.001),这间接表明超高压处理相比水煮处理可以更好地保留硬壳蛤蛤肉营养和滋味物质。该研究可为硬壳蛤超高压开壳处理液再利用提供理论基础。

Abstract: The large size and thick shell of Mercenaria Mercenaria make it easy to change the quality of the clams due to the long time required to open the shell during thermal processing. Ultra-high pressure(UHP)shell opening technology can better preserve the colour and aroma of the product, but it produces a large amount of UHP shell opening treatment solution. In order to make effective utilization of the treatment solution, the changes in flavour characteristics of freeze-dried powder(MFP1, MFP2, MFP3)with different UHP pressures(200 MPa, 250 MPa, 300 MPa, 6 min)were analysed by using freeze-dried powder(MFPS)of boiled shell-opening treatment solution of M. mercenaria as a control. The results showed that the flavours of the four groups of lyophilized powders differed significantly: in which the volatile flavour substances and contents of the control MFPS group were significantly lower than those of the three groups of MFP1, MFP2, and MFP3, but their protein and fat contents, sweetness, bitterness, and freshness values were highly significantly higher than those of the other three groups(P<0.001), which indirectly indicated that the UHP treatment could better retain the nutrients and flavour substances of the clam meat of M.mercenaria compared with the boiled treatment. This study can provide a theoretical basis for the reuse of UHP shell-opening treatment solution of M. mercenaria.

Key words: Mercenaria mercenaria, ultra high pressure, treatment solution, flavour
