Abstract

AbstractDecolorization is a necessary step before the extraction of okra pectin, and the reapplication of removed pigment will benefit hierarchical utilization of resources. Based on sweeping-frequency ultrasonic preprocessing (SFUP), effects of drying methods (hot air drying (HD), freeze-drying (FD)), sieves (of 60, 80, and 120 mesh) on removal rate and stability of okra pigment (OPI) were investigated. Color deepening caused by the formation of enzymatic products within 1 h of OPI degradation was explained. The extracted OPI was finally applied to noodles to check its stability further. Results showed that compared with non-ultrasonic treatment, SFUP increased removal rate of OPI with the maximum value of 49.32%, and further enhanced the stability of OPI when applied to noodles. OPI through sieves of 80 mesh owned brighter color and more excellent stability, and colored noodles with OPI through SFUP and FD had a small total color difference and strong stability.Keywords: Sweeping-frequency ultrasonic preprocessingdrying methodsifted okra powderpigment Ethical statementThe research does not involve animals or Humans, sensory evaluation and/or customer testing.

超声波扫频预处理提高了不同干燥和筛分方法对秋葵粉中色素的去除率和稳定性

【摘要】脱色是提取秋葵果胶前的必要步骤，脱色后的色素再利用有利于资源的分级利用。以扫频超声预处理(SFUP)为基础，研究了热风干燥(HD)、冷冻干燥(FD)、60目、80目、120目筛对秋葵色素(OPI)去除率和稳定性的影响。解释了OPI降解1 h内酶促产物形成导致颜色加深的原因。最后将提取的OPI应用于面条中进一步检验其稳定性。结果表明，与非超声处理相比，SFUP提高了OPI的去除率，最大值为49.32%，并进一步增强了OPI在面条中的稳定性。经过80目筛的OPI颜色更亮，稳定性更优，经过SFUP和FD的OPI着色面总色差小，稳定性强。关键词:扫频超声预处理干燥法筛选秋葵粉色素伦理声明本研究不涉及动物或人类，感官评价和/或客户测试。所有参与研究的个体都获得了知情同意。披露声明作者未报告潜在的利益冲突。作者贡献:张磊:数据整理，写作原稿，资金获取。张敖、周姗姗、王倩倩、胡振元、李成林、胡杨:调研、数据策展、写作-原稿。马海乐、周存山:监督。数据可用性声明支持本研究结果的数据可在合理要求下获得。基金资助:国家自然科学基金项目(31801599);江苏大学大学生科研项目(21A299, J21AE0134);江苏大学大学生创新训练计划(202110299889X)。同时也要衷心感谢Wahia hafiida和Xue Wang对这项工作的支持。
