新型富硒枸杞保健面包的研制

Development of a New Health Wolfberry Bread Enriched with Selenium

通过添加富硒酵母和枸杞浆研制出一种富硒枸杞保健面包,从而方便人体对硒元素的摄入,以提高人体的免疫力和抵抗力。在面包常规制作工艺中,加入微量元素硒和植物果实枸杞。面包制作好后,采用3,3'-二氨基联苯胺法检测成品面包中硒的含量,并利用单因素实验、质构分析和正交试验确定富硒枸杞保健面包的最佳制作方案。生产富硒枸杞保健面包的最佳工艺方案为:高筋面粉100 g,富硒酵母1.2 g,食盐0.8 g,白砂糖22 g,宁夏枸杞13 g,此条件下研制出的面包质量最佳,测得硒含量为0.5745 mg·kg^(-1)。结果表明,采用此方法制作的面包不仅口感松软细腻,还比一般面包更能补充营养,利于健康。

A kind of health bread enriched with selenium by adding selenium-rich yeast and wolfberry pulp was developed so as to facilitate the human body′s intake of selenium elements and improve the human body′s immunity and resistance.In the routine bread making process, trace element selenium and plant fruit wolfberry were added.After the bread was made, the content of selenium in the bread was determined by 3,3′-diaminobenzidine method.By using single factor experiment, texture analysis and orthogonal test, the best processing scheme of health wolfberry bread enriched with selenium was determined.The best processing scheme for the production of health wolfberry bread rich in selenium was as follows: 100 g of high-gluten flour, 1.2 g of selenium-rich yeast, 0.8 g of salt, 22 g of white granulated sugar and 13 g of Ningxia wolfberry.Under these conditions, the bread quality was the best, and the selenium content was 0.574 5 mg·kg;.The results showed that the bread made by this method was not only soft and fine in texture, but also more nutritious and beneficial to health than ordinary bread.
