摘要: 研究不同加工工艺对海带碘含量的影响。以灰化法对同加工工艺海带中的碘含量进行测定,并对结果进行方差分析。结果表明:杀青处理对碘含量的流失有显著影响(P<0.01),其中海水杀青的海带碘含量为0.0662%,极显著高于淡水杀青海带(P<0.01);海带制备成多聚糖膳食纤维,其碘含量显著低于鲜海带(P<0.01),其中海水杀青海带制备的海带膳食纤维的碘含量极显著高于淡水杀青及盐渍海带制备的样品(P<0.01);海带多聚糖膳食纤维加工成凝胶颗粒的过程中会造成碘含量的进一步流失。

Abstract: To study the influence of different processings of kelp on iodine, iodine content were determined by ashing method and subjected to analysis of variance. The results showed that, the blanching process had significant effect on the iodine erosion(P<0.01), the iodine content of kelp blanched by seawater was 0.0662%, significantly higher than that blanched by fresh water(P<0.01); the iodine content of dietary fiber produced by kelp was significantly lower than that of fresh kelp(P<0.01), and the iodine content of dietary fiber from seawater blanching kelp was significantly higher than that in fresh blanching kelp and saline kelp(P<0.01); the iodine content would lose during the processing of gel particle.
