2、保壓時(shí)間為10min處理刺參持水力達(dá)到最大。采用300MPa,60℃,10min處理刺參,硬度、黏附性、咀嚼性最大,此時(shí)刺參的質(zhì)構(gòu)最好,口感最佳。超高壓處理對(duì)刺參的功能成分影響不大,但與鮮刺參相比,多糖含量和膠原蛋白的含量差異較??;與水發(fā)刺參相比,多糖和膠原蛋白含量均明顯提高,說(shuō)明超高壓處理能夠減少有效成分的損失關(guān)鍵字:超高壓;刺參;持水力;功能成分;質(zhì)構(gòu)文章篇號(hào):1673—9078(2013)9.2081.2085EffectofHighPressure0nExpandingandQualityofDriedSeaCucumberWANGCheng-zhong,XIAMin-min(Col
