Micronutrient deficiencies are a public health concern among young children in low-income countries, and novel strategies are needed to improve the nutritional status of children at risk. One promising approach is the use of lipid-based nutrient supplements (LNS), which can be added to complementary food at the time of consumption. The optimal amount of zinc to include in LNS is uncertain, and concerns have been expressed about possible adverse effects of zinc on sensory characteristics of LNS. We conducted a series of acceptability studies of LNS containing either 0 or 10 mg of zinc per daily 20 g LNS dose among Burkinabe children 9-15 months old and their mothers. These acceptability studies included observations of children's consumption, maternal and child sensory reaction to the products using a 5-unit hedonic scale, a triangle test for detection of differences and a review of maternal reports of their child-feeding experiences during a 2-week home-feeding trial. The LNS products were well appreciated by the mothers and children during the sensory trials and the 2-week home-feeding trial. The addition of 10 mg zinc to LNS did not affect the consumed proportion of the offered porridge-LNS-mixture (P = 0.43). Results of the triangle test with mothers confirmed that there was no detectable difference between products containing 0 or 10 mg zinc per 20 g LNS dose. Most importantly, interviews and focus groups following the 2-week home-feeding trial indicated good acceptability of the products by mothers and their children.
微量营养素缺乏是低收入国家幼儿的公共卫生问题，需要新的策略来改善处于危险中的儿童的营养状况。一种有前途的方法是使用基于脂质的营养补充剂（LNS），可以在食用补充食物时添加到补充食物中。LNS 中包含的最佳锌量尚不确定，并且有人担心锌可能对 LNS 的感官特性产生不利影响。我们对布基纳法索 9-15 个月大的儿童及其母亲进行了一系列含有 0 或 10 毫克锌的 LNS 每日 20 克 LNS 剂量的可接受性研究。这些可接受性研究包括观察儿童的摄入量、母亲和儿童对产品的感官反应（使用 5 个单位的愉悦量表）、用于检测差异的三角形测试以及对母亲在为期 2 周的家庭喂养试验期间喂养经验的回顾。在感官试验和为期 2 周的家庭喂养试验中，母亲和儿童都非常喜欢 LNS 产品。在 LNS 中添加 10 毫克锌不会影响所提供粥-LNS-混合物的消耗比例（P=0.43）。用母亲进行的三角形测试结果证实，每 20 克 LNS 剂量中含有 0 或 10 毫克锌的产品之间没有可检测到的差异。最重要的是，在为期 2 周的家庭喂养试验后进行的访谈和焦点小组表明，母亲及其子女对这些产品的接受度良好。
