Folate deficiencies are widespread in Africa due to predominantly cereal-based diets. The objective of this work was to test the feasibility of using folate-producing microorganisms to increase folate content of tef , a traditional Ethiopian fermented staple food. To this end, a strain of previously isolated from fermented tef batter and a commercial were used alone and in combination to prepare . Ten successive fermentations using backslopping from the fermented batter prepared with inoculation were performed to mimic the traditional backslopping. The highest folate content was obtained with (53.5 μg/100 g fresh material). All the combinations were efficient and could cover up to 22 % of the recommended nutrient intakes. All prepared with selected inoculums were preferred by sensory panelists to the traditional one. This work demonstrates the possibility to increase folate intake using folate-producing microorganisms in the conditions normally encountered in households.
由于非洲的饮食主要以谷物为主，叶酸缺乏现象普遍存在。这项工作的目的是测试利用产叶酸微生物来提高埃塞俄比亚传统发酵主食苔麸叶酸含量的可行性。为此，将一株先前从发酵苔麸面糊中分离出的菌株和一种商业菌株单独及混合使用来制备苔麸。使用接种了发酵面糊回接的方法进行了十次连续发酵，以模拟传统的回接过程。使用[具体菌株名称]获得了最高的叶酸含量（53.5微克/100克新鲜材料）。所有组合都很有效，可满足高达22%的推荐营养素摄入量。与传统苔麸相比，所有用选定接种物制备的苔麸更受感官评价小组成员的青睐。这项工作证明了在家庭通常遇到的条件下，利用产叶酸微生物增加叶酸摄入量的可能性。
