Development of a vitamin A-rich weaning food and child cereal from dried and "instantized" sweet potato buds. Final report.
[Unpublished] 1992 Oct.  p. (PN-ABP-099)In 1992, the Sweet Potato Buds (SPBs) I Pilot Project in Guatemala aimed to reduce the prevalence of hypovitaminosis A, which is responsible for nutritional eye damage (xerophthalmia) and impaired health. It consisted of multiple activities, which included documentation of the batch-scale preparation of dried SPBs in industrial processing, analyses of the provitamin A carotenoids and vitamin A content, determination of the acceptability and organoleptic characteristics of gruels and purees based on reconstituted SPBs, testing different packaging options, and determination of the culinary possibilities of low income households that produce acceptable consumption forms. Storing buds in packing materials with air (about 20% oxygen) and a large surface area of the flake caused oxidative deterioration of beta-carotene and retinol equivalent (RE) values. The loss of beta-carotene between March and July for all packaging options stood at 69%. Foil packaging was significantly better than plastic packaging (p < 0.05). In both the urban and rural area, most mothers (84-94%) considered the acceptability of the SPB gruel and puree to be good or outstanding. Most children tried the gruel and puree. In the urban area, 70% asked for more puree and 84% wanted more gruel. The corresponding figures for the rural area were 62% and 80%, respectively. Mothers claimed they would give SPB to their children, even when they were ill. Most mothers from both the urban and rural areas considered SPB to be good, easy to prepare, easy to mix, and easily used in other recipes.
