Formulation of local food multimix sprinkle to enhance nutritional adequacy of preschool children in southernmost provinces of Thailand

@#Introduction: This study aimed to formulate an effective Food Multimix-Sprinkle (FMM-S) by using locally available materials. Methods: Fish (Threadfin bream), cow liver, and orange fleshed sweet potato (OSP) were cooked and dried by using applicable household (HH) method and drum drying (DD). Then, the dried materials were milled and sieved through a 20 mesh screen. Fish, cow liver, and OSP sprinkles were mixed in various proportions to meet nutrient level targets [at least 30% of Thai Recommended Dietary Allowance (RDA) for 1-3 years old children per 15 g serving size]. Results: Six alternative mixes were formulated. The mixture of 3 g of liver, 7 g of fish, and 5 g of OSP (3:7:5) when processed by HH method, and the mixture of 4 g of liver, 8 g of fish, and 3 g of OSP (4:8:3) when processed by DD method, had significant advantage in preference scores in all attributes over the others. Nutritional values of these formulas were 37-55% RDA of protein, 146-194% RDA of vitamin A, and 30-40% RDA of iron for a serving size. Conclusion: This study demonstrated that household preparation, as well as preparation using drum drying could be used to process raw fish, cow liver, and OSP into a sprinkle mix. The FMM-S provided appropriate amounts of protein, vitamin A, and iron to supplement nutrient intake in pre-schoolers. However, a consumer test is needed to ensure acceptance by the target population.

Avaliação da concentração de minerais e dos fatores antinutricionais fitato e oxalato em multimisturas da Região Metropolitana de Belo Horizonte/MG / Evaluation of mineral concentration and anti-nutritional factors phytate and oxalate in Multimix from the Metropolitan Region of the City of Belo Horizonte/MG

In this work, samples of Multimix, both for industrial use and prepared by the Child's Pastoral in different parts of the metropolitan region of Belo Horizonte / MG were analyzed for determining the concentration of phytates, oxalates and even the minerals K, Mg, Mn, Na, Zn, Fe and Ca. The results showed, in most cases, the concentration of minerals below the recommended daily intake for portions of multi-mixture used, 5 and 22.5g. The concentration of anti-nutritional factors was assessed by the molar ratios of phytate / Fe, phytate / Zn, phytate / Ca, phytate x Ca / Znand Ca / oxalate. The obtained values, in almost all cases > 1, associatedwith low concentration of minerals in the environment, suggest a low bioavailability of essential minerals, which reinforces the debate on the effectiveness of Multimix as a nutritional supplement.

En este trabajo, muestras de "multimistura" del tipo industrial y preparadas por la Pastoral del Niño en diferentes puntos de la región metropolitana de Belo Horizonte, Minas Gerais, Brasil, fueron analizadas para determinar la concentración de fitatos, oxalatos y los minerales K, Mg, Mn, Na, Zn, Fe y Ca. Los resultados mostraron, en la mayoría de los casos, una concentración de minerales abajo de la ingesta diaria recomendada, para las porciones diariasde "multimistura" ingerida: 5 y 22,5g. La concentración de factores antinutricionalesse evaluó mediante las relaciones molares defitato/Fe, fitato/Zn, fitato/Ca, fitato x Ca/Zn y Ca/oxalato. Los valores obtenidos, en casi todos los casos son mayores que la unidad (> 1), esto, asociado a una baja concentración de mineralesen el medio, permite suponer que hay baja biodisponibilidad de minerales esenciales, lo que refuerza el debate sobre la eficacia de la "multimistura" como suplemento nutricional.

Neste trabalho, amostras de multimistura do tipo industrial, preparadas pela Pastoral da Criança em diferentes pontos da região metropolitana de Belo Horizonte/MG, foram analisadas para determinação da concentração dos fatores antinutricionais fitato e oxalato e ainda dos minerais K, Mg, Mn, Na, Zn, Fe e Ca. Os resultados mostraram, na maior parte dos casos, concentração dos minerais abaixo do recomendado para ingestão diária nas porções utilizadas da multimistura, 5 e 22,5g. A concentração dos fatores antinutricionais foi avaliada através das razões molares fitato / Fe, fitato / Zn, fitato / Ca, fitato x Ca / Zn e Ca / oxalato. Os valores obtidos, em quase todos os casos > 1, associados à baixa concentração dos minerais no meio, sugerem uma baixa biodisponibilidade dos minerais essenciais, o que reforça o debate sobre a eficácia da multimistura como complemento nutricional.
