, a green leafy vegetable, is a good source of minerals and vitamins which could be consumed as part of diet to improve human health and well-being. Drying leaves could make it readily available for use as a food fortificant. The objectives of the study were to determine micromineral and -carotene content of dried leaves, and leaf-incorporated local dishes, and also assess school children's (4-12 yr) acceptability of dried leaf-incorporated local dishes and feasibility of introducing dried leaves into a school lunch menu. leaves were solar dried, milled into powder, and packaged into polythene bags. Moisture level in the dried leaves and pH were determined. Minerals in the leaf powder were determined by Atomic Absorption Spectrophotometry (AAS). Beta-carotene levels were determined by spectrophotometry. Acceptability tests of dishes fortified with leaf powder were conducted with score sheets (Smileys) on a 5-point hedonic scale of "Like Extremely" to "Dislike Extremely", and dishes ranked to determine preference. Dried leaves contained high levels of micronutrients: 0.36 ± 0.04 mg/100 g Copper (Cu); 5.80 ± 0.68 mg/100 g Manganese (Mn); 20.96 ± 1.37 mg/100 g Iron (Fe); 6.79 ± 1.82 mg/100 g Zn; and 21.42 ± 1.67 mg/100 g -carotene. The dishes showed significant levels of these minerals compared to the nonfortified dishes (< 0.05). leaf-fortified dishes were also highly acceptable to the children (highest mean score of 5.0 ± 0 of 5 and lowest of 3.50 ± 1.43 of 5). leaf powder contains high levels of the micronutrients -carotene, Zn, Mn, and Fe, comparable to levels found in amaranth and spinach. leaf-fortified local dishes were well accepted by children in Ada-East district. leaf fortified dishes could be good sources of -carotene and other minerals for children vulnerable to malnutrition in Ghana.
[蔬菜名称],一种绿叶蔬菜,是矿物质和维生素的良好来源,可作为饮食的一部分食用,以改善人类健康和福祉。将[蔬菜名称]叶干燥可以使其便于用作食品强化剂。本研究的目的是测定干燥[蔬菜名称]叶、添加了[蔬菜名称]叶的当地菜肴中的微量矿物质和β-胡萝卜素含量,并评估学龄儿童(4至12岁)对添加了干燥[蔬菜名称]叶的当地菜肴的接受程度以及将干燥[蔬菜名称]叶引入学校午餐菜单的可行性。将[蔬菜名称]叶进行日晒干燥,磨成粉末,然后包装到聚乙烯袋中。测定干燥叶中的水分含量和pH值。通过原子吸收分光光度法(AAS)测定叶粉中的矿物质。通过分光光度法测定β-胡萝卜素水平。使用评分表(笑脸表情)以从“极其喜欢”到“极其不喜欢”的5分享乐量表对添加了[蔬菜名称]叶粉的菜肴进行可接受性测试,并对菜肴进行排名以确定偏好。干燥的[蔬菜名称]叶含有高水平的微量营养素:0.36±0.04毫克/100克铜(Cu);5.80±0.68毫克/100克锰(Mn);20.96±1.37毫克/100克铁(Fe);6.79±1.82毫克/100克锌(Zn);以及21.42±1.67毫克/100克β-胡萝卜素。与未强化的菜肴相比,这些菜肴中的这些矿物质含量显著(P<0.05)。添加了[蔬菜名称]叶的菜肴也很受孩子们的欢迎(平均得分最高为5分制中的5.0±0,最低为5分制中的3.50±1.43)。[蔬菜名称]叶粉含有高水平的微量营养素β-胡萝卜素、锌、锰和铁,与苋菜和菠菜中的含量相当。在阿大东区,添加了[蔬菜名称]叶的当地菜肴很受孩子们的欢迎。添加了[蔬菜名称]叶的菜肴可能是加纳易患营养不良的儿童获取β-胡萝卜素和其他矿物质的良好来源。
