Description

EXAMPLES

Example 1

(1) 408.5 g Maltodextrin and 432.2. g HiCap IMF and 210.7 g Glucidex 28 E were added to 600 g distilled water. The mixture was stirred and after a few minutes the mixture was heated to about 60° C. After 20 minutes 10.8 g sodium ascorbate was added under stirring. 10 minutes later 9.6 g lutein was added and the mixture was vigorously dispersed.

(2) Afterwards the suspension was spray dried.

(3) The following table shows the amounts of the various ingredients after spray drying:

(4) TABLE-US-00001 Ingredients Amount [wt-%] Lutein 1.2 HiCap IMF 40.2 Maltodextrin 38.0 Glucidex 28 E 19.6 Na-Ascorbate 1.0

(5) The average size of the inner phase D[3,2] was 3.19 μm and the average particles size was 45.92 μm.

Example 2

(6) The same process as in Example 1 was repeated but instead of Glucidex 28 E sugar was used.

(7) The following table shows the amounts of the various ingredients after spray drying:

(8) TABLE-US-00002 Ingredients Amount [wt-%] Lutein 1.2 HiCap IMF 40.2 Maltodextrin 38.0 Sugar 19.6 Na-Ascorbate 1.0

(9) The average size of the inner phase D[3,2] was 3.02 μm and the average particles size was 81.82 μm.

(10) Both compositions did not bleed when added to a premix or a infant food formulation. Furthermore, no color formation was observed when the infant food formulation (baby milk powder) comprising one of these compositions were dissolved in water.

Example 3

Baby Milk Powder Comprising Composition of Example 1

(11) The composition of Example 1 was used adding to a baby milk powder formulation. 0.83 g of the powderous composition of Example 1 were incorporating (by mixing).
