Formulation of Carrot (Daucus carrota) Extract Effervescent Powder

Carrot extract powder is product which soluble in both of cold and hot water. However, a mild stirring processed is chill needed to accelerate the solubility. Therefore, effervescent principles were introduced to improve the solubility character. This research was conducted to evaluate the various effervescent formulas on the physical properties and the consumer preferences. Carrot extract effervescent were prepared based on five formulas, which containing 200 g carrot extract powder on each formula. The ratio of sodium bicarbonate and acids (tartaric and citric acid) were 2.5 : (2 : 1) (formula 1), 2.5 : (1.5 : 1) (formula 2), 3.5 : (2 : 1) (formula 3), 3.5 : (1.5 : 1) (formula 4) and 3.5 : (1.5 : 1) (formula 5). All materials were then dry mixed and screened with 20 mesh size of wire (stainless steel). The powders were analyzed the flow ability, angel of repose, compressibility, disintegration time and consumer preferences. The result showed carrot extract effervescent powder prepared with 200 g of carrot extract powder, 135 g of sodium bicarbonate, 108 g of tartaric acid and 54 g of citric acid (formula 1) was the preferable product. The water and beta-carotene content were 2.23 % and 0.29 mu g/g (dw) respectively.
