中文摘要: 以秘鲁鱿鱼为研究对象,利用超声波结合除酸液浸泡处理进行除酸,通过测定处理不同时间后秘鲁鱿鱼片的挥发性盐基氮(total volatile basic nitrogen,TVB-N)含量、pH值、持水性、剪切力、质构特性及色泽的变化规律,评价超声波辅助除酸液处理对秘鲁鱿鱼品质的影响。试验结果表明,超声波辅助处理能有效缩短秘鲁鱿鱼的除酸时间,增加鱿鱼的持水性和嫩度,改善除酸后秘鲁鱿鱼的质构特性,同时对鱿鱼的色泽无显著影响。综合考虑,超声辅助除酸液处理60 min 时对秘鲁鱿鱼的品质影响较小。
Abstract:Deacidification of Dosidicus gigas was carried out by ultrasonic combination with deacidizing liquid in this study. The effects of ultrasonic-assisted deacidification treatment on the quality of Dosidicus gigas were evaluated by measuring the TVB-N content,pH value,water holding capacity,shear force,texture properties and color changes after different treatment times.The results showed that the ultrasonic-assisted deacidification treatment could effectively shorten the deacidification time of Dosidicus gigas,increase the water holding capacity and tenacity of squid,and improve the texture properties of Dosidicus gigas after deacidification.Meanwhile,the ultrasonic-assisted deacidification had no significant effect on the color of squid. In general,the quality of Dosidicus gigas was less affected by ultrasonic-assisted deacidification for 60 min.
