中文摘要:

      目的 研究盐渍海蜇皮中的铝脱除方法。方法 将盐渍海蜇皮分别浸泡在超纯水、pH为3.75的弱酸性电解水、0.5%乳酸钙溶液以及0.5%弱酸性电解水+乳酸钙复合溶液4种不同脱铝液中, 设置不同浸泡时间, 对浸泡后海蜇皮的质构、感官、溶胀率、粗蛋白含量以及铝含量进行测定。结果 弱酸性电解水能够有效降低盐渍海蜇中的铝含量, 乳酸钙溶液则可以明显缓和脱铝后海蜇硬度、弹性以及溶胀率的降低, 使海蜇维持良好的感官和组织形态。得到盐渍海蜇的最佳脱铝液为0.5%弱酸性电解水+乳酸钙复合溶液, 最佳浸泡时间为3 h。结论 0.5%弱酸性电解水+乳酸钙复合溶液可有效降低盐渍海蜇皮中铝的含量, 同时使海蜇保持良好的品质。

英文摘要:

      Objective To study the method of aluminum removal from salted jellyfish skin. Methods Salted jellyfish were soaked in 4 kinds of different dealuminizing solution including ultrapure water, weak acid electrolytic water with pH 3.75, 0.5% calcium lactate solution and 0.5% weak acid electrolytic water+calcium lactate, the texture, sensory, swelling rates, crude protein content and the aluminum content of jellyfish under different soaking time were measured. Results Weak acid electrolytic water could effectively reduce the aluminum content in salted jellyfish, calcium lactate solution could obviously ease the hardness, elasticity and swelling rates of jellyfish after dealuminization, so as to maintain good sensory and organizational morphology of jellyfish. The best dealuminization solution was 0.5% weak acid electrolytic water+calcium lactate solution, and the best soaking time was 3 h. Conclusion 0.5% weak acid electrolytic water+calcium lactate solution can effectively reduce the content of aluminum in salted jellyfish skin and keep the jellyfish good quality.
