Abstract
The present invention relates to extrudates comprising water-soluble vitamins and other micronutrients. They are obtainable by adiabatic extrusion. During extrusion, temperature is controlled by the viscosity of the composition which is being extruded. Pasteurization temperature is reached, i.e. the extrudates of the invention meet the requirements set out in microbiological guidelines.
Claims21
A pasteurized extrudate which comprises a composition comprising, based on total weight of the composition:
- at least 10 wt. % of a starch powder,
- at least 10 wt. % of semolina,
- at least 5 wt. % of at least one water-soluble vitamin, and
- water, wherein
- the starch powder and semolina are separate components of the composition and are present in a weight ratio of the starch powder to the semolina of 5:1 to 1:5, and wherein
- the starch powder has a particle size d(0.9) from 10 μm to 300 μm when measured on the Malvern Mastersizer 2000 connected to a Scirocco 2000 dry dispenser unit with a 60% vibration feed, 0.1 bar dispersive air pressure and measured with a continuous obscuration of 7.0±1% over 35 s, and wherein
- the extrudate is pasteurized by extrusion under adiabatic conditions.
