摘　　要：[目的]探究马铃薯块茎在加工中微量元素硒的分布特性,为生产开发富硒马铃薯产品提供理论和实践依据。[方法]选择高硒土壤中生产的马铃薯块茎,按传统工艺加工薯片和淀粉,测定加工产品和副产品含硒量,分析硒回收率和流失率。[结果]以蒸汽加热方式脱水加工薯片硒回收率较高,达到39.63%,比水煮脱水加工薯片高近5个百分点,但有超过60%的硒流失;加工的淀粉含硒量只有原料块茎鲜基含硒量的9%,淀粉加工硒回收率仅为13.91%。[结论]通过传统的加工工艺不可能生产出富硒马铃薯淀粉,加工富硒马铃薯薯片也有必要改进传统的加工工艺。[Objective] In order to provide theoretical and practical basis for the production and development of selenium-enriched potato products,to explore the distribution characteristics of trace element selenium in processing potato tuber. [Method] To select potato tubers produced in high selenium soil,and processed into potato chips and amylum in the traditional way,then determine the selenium content of the products and by-products,analyze the selenium recovery rate and loss rate. [Result]The recovery rate of selenium was higher when the steam heating method was used for the processing,nearly 5 percent higher than the delydration by boiling water,which reached 39. 63%,but there are still more than60% of the selenium was lost,the selenium content of starch is only 9% of the amount of selenium in the tubers,and the recovery rate of the processing is only 13. 91%. [Conclusion]Selenium-enriched potato amylum could not produce by traditional processing technology,the processing of selenium-enriched potato chips is also necessary to improve the traditional processing technology.
