SERRANO ROMERO, Aracelly del Carmen et al. Sensory evaluation among Nicaraguan school-age children of a sweet potato (Ipomoea batatas) snack prepared with and without sweet potato leaves. Perspect Nut Hum [online]. 2011, vol.13, n.2, pp.191-202. ISSN 0124-4108.

Objective: acomplete a sensory evaluation of orange-fleshed sweet potato (OFSP) clone 440189. Materials and methods: a descriptive study was undertaken with a convenience sample of 290 Nicaraguan school-age children attending grades 3 to 6, who taste-tested a ''sweet potato cake'' recipe. Snack A had sweet potato leaves added to it; snack B did not. First, 33 mothers opined about the snacks. Then, children tested snacks A and B, assigning a value of 1 to 5 (from ''I don´t like it very much'' to ''I like it very much'') to each and indicating which snack they preferred. Results: most of the women gave a positive evaluation to the snacks in terms of ease of preparation, time required, access to ingredients, probability that the children would accept them, and possibility of including them in the school menu. Acceptability scores assigned by the children were high (mean ± SD of 4,5 + 0,7) and similar between the snacks (p=0,91). Fifty one percent preferred snack A and 49% preferred snack B (p=0,56). Conclusions: both snacks were accepted by the mothers and children suggesting that it is feasible to include OFSP clone 440189 into Nicaraguan school children´s meals.
