[Development of a milk beverage based on pumpkin flakes].

Vitamin A deficiency is one of the majors public health problems in Brazilian Northeast, and among other causes may be concerned to precocious weaning. Aiming at reducing this problem, a dehydrated product based on powdered milk and pumpkin flakes was developed to act as a carotene source at weaning period. Pumpkin flakes were obtained by drum drying at a 6 atm steam pressure, 0.75 m2 contact surface and 1 rpm, and had their content of carotenoids, beta carotene, centesimal composition molds and yeast and faecal coliforms evaluated. The flakes were added to sugar and whole powdered milk according to FAO/WHO nutritional recommendation to 6-12 months old children and submitted to acceptability test by a 6 judges' panel. The results showed that the drying process had a 7% efficiency score and the flakes composition presented 4.84% moisture; 4.0% protein; 5.5% ash; 1.30% fat; 6.22% fiber; 78.14% carbohydrates; 115.08 micrograms/g total carotenois and 80.64 micrograms/g beta-carotene content. No coliforms were detected and molds and yeast content was 4.0 x 10(2) CFU/g. The powdered formulation properly diluted in water supports 45% of the RDA for children (calories, protein, carbohydrates and lipids) and 100% vitamin A and protein considering a 400 ml/day ingestion.
