“…Those values were similar to the ones observed for commercial tucupi (L = 59.76±0.01; a* = -2.71±0.12; b* = 45.82±0.08), which shows the typical yellow color of tucupi was preserved in the product. Tucupi's yellow color is due by the presence of carotenoids (Marinho & Arkcoli, 1981). Figure 5 presents the rheological curves of shear stress and viscosity versus shear rate for the creamy paste with 10% tucupi obtained at 25, 40, and 60 °C.…”

Tucupi, a fermented product obtained from cassava (Manihot esculenta Crantz) is widely employed in the cuisine of the Northern region of Brazil, however, its industrial application is incipient. This study used tucupi to prepare a creamy paste, which underwent sensory and rheological evaluation. Paste formulations with 5 to 20% concentrated tucupi were obtained. An acceptance test was used to assess the product's acceptability regarding the attributes of color, aroma, flavor, texture, and overall impression. A purchase intention test of the product was also applied. The product's rheology was studied at 25, 40, and 60 °C and the activation energy (E a ) was estimated. The internal preference mapping indicated that the paste formulation with 5% and 10% tucupi were the most accepted by the judge, but only the 10% tucupi paste was characterized. Proportions greater than 15% tucupi influenced negatively in the flavor and texture of the product. Purchase intention test showed that 99% of the judges demonstrated interest in purchasing the product. The product presented 72.7% moisture, 10.4% lipids, 0.5% proteins, 2.1% ashes, 14.3% carbohydrates, and 7.4 μg/g β-carotene. According to the rheological assays, the paste presented characteristics of a pseudoplastic fluid. The Herschel-Bulkley model proved efficient to predict the flow curves for the product in the temperature range tested, for which E a was estimated at 7.49 kJ/mol.

“…Na Amazônia Brasileira a deficiência de vitamina A tem sido observada desde os primeiros estudos nutricionais realizados nessa região (Silva, 1959;Lowenstein,1967). Entretanto, as informações registradas na literatura, procedentes da Amazônia Ocidental Brasileira, sobre a epidemiologia da hipovitaminose A, ainda são escassas (Marinho et al, 1981(Marinho et al, , 1991.

RESUMO -Com objetivo de avaliar o consumo de energia, vitamina A, zinco e proteínas, bem como os hábitos alimentares de pré-escolares das capitais de Roraima (Boa Vista),Amazonas (Manaus) e Rondônia (Porto Velho) foi realizado um inquérito alimentar em 54, 238 e 78 crianças de ambos os sexos (sub-amostra de inquérito nutricional mais abrangente),respectivamente, em creches e pré-escolas, mediante os métodos recordatório de 24 horas e de freqüência de consumo de alguns alimentos fontes de vitamina A, em entrevista com a mãe ou responsável pela criança. Os resultados mostram que os alimentos mais consumidos foram pão, bolacha e biscoito, com 98,3%, seguidos pelo açúcar (95,1%), arroz (92,4%), óleo vegetal (86,0), farinha de mandioca (77,4%), tomate (70,1%) e café (69,5%). O consumo de alimentos de origem animal foi responsável por quase dois terços do total ingerido de vitamina A. Quanto à distribuição dos alimentos fontes de vitamina A, observou-se semelhança do seu consumo nas três cidades estudadas. O percentual de adequação de consumo evidenciou que a proteína foi o único nutriente consumido em níveis superiores à recomendação da "National Research Council", enquanto o aporte dietético de vitamina A foi de 84,0%, 68,4% e 63,8%, em Boa Vista, Manaus e Porto Velho, respectivamente, com inadequação, inclusive, para energia e zinco. Observou-se um padrão alimentar monótono e limitado, com baixo consumo de fontes de vitamina A pré-formada, de hortaliças e de frutas fontes de carotenóides pró-vitamínicos A típicos da Região Amazônica, como buriti, tucumã, pupunha e manga, quase todas sazonais, que não estavam na sua época por ocasião do inquérito. ABSTRACT -The objective of this study was to evaluate the intake of energy, vitamin A, zinc and protein, as well as food habits of 54, 238 and 78 pre-school children of both sexes, 3 to 6 years old, (wide hange of subsample of inquiry including nutritional), in the capitals of Roraima (Boa Vista),Amazonas (Manaus) and Rondônia (Porto Velho), respectively. Dietary assessments were performed with the parents or someone responsible for the child, using the 24 hour recall and food frequency questionnaire methods. Our results showed that bread, crackers and cookies were the most consumed foods (98,3%), followed by sugar (95,1%), rice (92,4%), vegetable oil (86,0), manioc flour (77,4%), tomato (70,1%) and coffee (69,5%).The intake of animal products was responsible for almost 2/3 of the total intake of vitamin A. The pattern of vitamin A sources consumption among the three cities was similar. Protein was the only nutrient in which the intake exceeded the recommendation, whereas zinc and energy intake were inadequate. Additionally, the consumption of vitamin A was, respectively, 84,0%, 68,4% and 63,8% in Boa Vista, Manaus and Porto Velho, of the recommended values.

“…Zinc deficiency had been shown to limit RBP production in malnourished children in India (Shingwekar et al 1978), and to impair the efficiency of beta carotene utilization in rats (Takruri & Thurnham 1982). Half of the dietary vitamin A amongst the poor population of Manaus came from fruit and vegetable sources (Shrimpton 1984), and especially from the carotene in the yellow cassava flour (Marinho & Arkcoll 1981) commonly consumed in the Amazon.…”

The effects of zinc supplementation on levels of zinc, retinol and carotene in serum and breast milk were investigated in a double blind controlled prospective study amongst 66 poor urban Amazonian mothers in 1981. The mothers predominantly breast-fed their infants for the first five months of life and took supplements from soon after birth. Milk retinol levels were already significantly higher in zinc supplemented (ZS) than non-zinc supplemented (NZS) mothers by one month post-partum, and by four months had risen significantly in the ZS mothers but fallen in NZS mothers. At four months post-partum, milk retinol levels of ZS mothers were near normal and double those of NZS mothers. The effect of zinc supplementation on these retinol levels was possibly associated with an increased absorption and utilization of dietary carotene, since milk carotene levels also increased in ZS mothers to levels three times those of NZS mothers at four months post-partum. This impact of zinc supplementation on maternal and breast milk vitamin A levels has not been shown previously and is of potential relevance where zinc and vitamin A deficiency are common.
