DESCRIPTION:
BRIEF SUMMARY
The present invention relates to a substantially free-flowing powder product and to a method for its preparation.
Certain surface-active products, for example food-improving surface-active agents such as emulsifiers or aerating agents (aerating agent is a designation used in the food industry for an emulsifier which is used for whipping purposes, in other words for preparing emulsions where air constitutes the disperse phase) for use in the food industry, such as emulsifiers which are partial fatty acid esters of glycerol or glycerol condensates, are substances of a fat-like consistency and behaviour, or expressed in another manner, substances of a lipid character.
For addition to the products which they are to aerate or emulsify, for example bread dough or cake mixes, they are suitably used in the form of a powder, preferably a free-flowing powder.
It is known to prepare such powders by spray-drying or by application of the surface-active substance on sucrose particles as a carrier. Thus, one known method for preparing such powders is to spray-dry an emulsion made from skim milk or whey and an emulsifier. Often, it is necessary to take special precautions to spray-dry the emulsion under particularly gentle conditions in order to avoid any substantial impairment of their surface-active properties. Spray-drying requires extensive apparatus and requires that the surface-active substance be converted into a dissolved or suspended state from which the solvent is removed in the spray-drying process. Owing to the parameters of the spray-drying process, there are certain limitations with respect to the composition of the final product, its specific gravity, etc. The method in which sucrose is used as a carrier comprises applying an emulsifier on sucrose particles, e.g. icing sugar, by mill mixing. In this method, it is normally not possible to apply more than about 10-15% by weight of the surface-active substance on the sucrose. This may be a too low concentration of emulsifier for certain purposes, and an emulsifier applied on sucrose will necessarily introduce a certain amount of sucrose into the products in which it is used, which is not always desired.
The present invention provides a simple and economic method for preparing a desirable novel substantially free-flowing powder surfactant product.
The product of the invention is a substantially free-flowing powder product comprising one or several surface-active substances applied on a particulate carrier in an amount of at least 10% by weight, calculated on the weight of the product, with the proviso that the carrier does not consist of sucrose.
The surface-active substance is normally a surface-active substance of lipid character, in particular a food-improving surface-active such as e.g., an emulsifier or aerating agent for use in the food industry, in particular the bakery industry.
The carrier is preferably of vegetable origin, and interesting carriers are carriers selected from flours, starches, mono- and disaccharides and pentosans and mixtures thereof, optionally with an admixture of material of vegetable fibre origin.
It is generally preferred that the carrier is one which contains or consists of starch.
As examples of such carriers which are of great interest in connection with surface-active substances for use in the food industry may be mentioned tuber starches or flours such as potato starch, batat starch and yam starch, sago starch, bean flour and pea flour, cereal starches or flours such as rice starch, wheat starch, rye starch, barley starch, oat starch, rice flour, wheat flour, rye flour, barley flour, oat flour, and maize starch, maltodextrins, dextrose, fructose, and mixtures thereof.
It is, however, within the scope of the invention to use a carrier which is of animal origin, e.g. bone meal or blood meal, which may be of interest in connection with certain surface-active substances, or of inorganic origin, such as chalk, bentonite, or talc, which may especially be of interest in connection with industrial surface-active substances.
