Abstract
The present invention relates to a use of octenylsuccinyl anhydride substituted starch (OSA starch) for increasing the dry weight content and/or the fat content of a liquid composition that is subjected to a spray-drying step, and also to a process for preparing powders. The present invention enables the spray-drying of emulsions that contain a high amount of fat. The present invention also relates to the powder products obtainable by the process and nutritional products such as an infant milk powder, grow up milk, toddler milk or as a medical nutritional product that can be formulated therewith.
Claims15
A method for producing a nutritional powder, comprising fat, an emulsifier, digestible carbohydrates, and proteinaceous material comprising the steps of
- a. preparing a liquid containing the digestible carbohydrate and the emulsifier in water by adding the digestible carbohydrate and the emulsifier consecutively or simultaneously to water at a temperature of between 50 and 90 deg C., optionally using a homogenization step;
- b. providing a fat ingredient containing at least one fat;
- c. combining the liquid and the fat ingredient to provide a pre-emulsion;
- d. performing a homogenization step to homogenize the pre-emulsion to form an emulsion, and optionally increasing the dry matter content of the emulsion by a concentration step;
- e. spray drying the emulsion obtained in step d to provide a base powder;
- f. optionally further drying the base powder of step e;
- wherein the emulsifier is octenylsuccinyl anhydride substituted starch (OSA starch),
- wherein the fat content of the base powder is at least 32 wt % on total dry weight of the base powder, wherein the free fat content is less than 3 wt % based on total weight of the fat,
- g. adding one or more dry ingredients by dry blending, to obtain the nutritional powder,
- wherein the nutritional powder is an infant formula, follow-on formula or growing-up milk,
- wherein the nutritional powder comprises 40-60 wt. % of the base powder,
- wherein the nutritional powder contains 95-100 wt. % amino acids based on total proteinaceous material.
A nutritional powder comprising
- 40-60 wt % of base powder, wherein the base powder comprises fat, digestible carbohydrates and emulsifier, wherein the fat content is at least 32 wt % based on total dry weight of the base powder, the free fat content is less than 3 wt % based on total weight of the fat, and the emulsifier is OSA starch;
- and
- one or more ingredients selected from the group consisting of a digestible carbohydrate, a protein, hydrolysed protein, peptide, amino acid, a non-digestible carbohydrate, biotic, vitamin and mineral,
- wherein the nutritional powder is an infant formula, follow-on formula or growing-up milk,
- wherein the nutritional powder comprises fat, an emulsifier, digestible carbohydrates, and proteinaceous material and contains 95-100 wt. % free amino acids based on total proteinaceous material.
