Abstract:
The invention relates to a method of preparing a double emulsion comprising a) preparing an emulsion comprising at least two liquid phases by bringing a first polymer (A) and a second polymer (B) into contact with each other in a solvent, wherein the concentrations of the polymers are chosen such that, upon bringing them into contact, a phase separation occurs, thereby forming drops of a first liquid phase in a second liquid phase, wherein, in the first phase, the weight concentration of the polymer A (CA) is higher and the weight concentration of the polymer B (CB) is lower than the respective concentrations in the second phase; b) dispersing the emulsion in a third liquid phase, which third phase comprises the polymer A in a CA which is higher than in the second phase and the polymer B in a CB which is lower than in the second phase, thereby forming the double emulsion, comprising at least one discontinuous phase (1)—with a relatively high CA and a relatively low CB—enclosed by a surrounding phase (2)—with a relatively low CA and a relatively high CB—which discontinuous and surrounding phase are dispersed in a continuous phase (3)—with a relatively high CA and a relatively low CB; and wherein the solvent in said liquid phases is the same or the solvents are at least, in the absence of the polymers, soluble in one another or completely miscible at 25° C.
Abstract:
The present invention relates to method to produce a dairy based food composition comprising protein comprising the steps (a) Treating the milk such that at least 98% of the pathogens is removed, (b) Treating the milk with a microfilter of a poresize of 0.01-2 micron such that at least a casein rich fraction and a serum protein rich fraction is obtained, wherein the milk is subjected to a heating treatment before or after the microfiltration and wherein during the production the milk and products obtained from the milk are not subjected to a heat treatment at a temperature above 90° C., and wherein the serum protein rich fraction and/or the casein rich fraction is processed into a food product. The invention also is directed to products made by the process.
Abstract:
The invention is directed to a method to produce a water-in-oil-in-water (w/o/w) emulsion, comprising: a. preparing a water-in-oil (w/o) emulsion; b. atomizing said w/o emulsion in the presence of a carrier material comprising at least a water soluble matrix material and at least one emulsifier, to form agglomerates; c. dispersing said agglomerates in an aqueous liquid, such as water or an aqueous solution. Also provided is a new instant powder (obtained after step b) that can be used to prepare the w/o/w emulsion. The emulsion of the invention is advantageously suited for the encapsulation of active components.
Abstract:
The present invention relates to a microencapsulate comprising microcapsules having a diameter of 0.1 μm to 25 μm, said microcapsules comprising: —a core particle having a diameter of 90 nm to 23 μm and containing at least 3% of the active component by weight of said core particle; and—a coating that fully envelops the core particle and containing at least 20 wt. % of a hydrophobic polymer selected from cellulosic ethers, cellulosic esters, zein, shellac, gluten, polylactide, hydrophobic starch derivatives, polyvinyl acetate polymers, polymers or copolymers derived from an acrylic acid ester and/or a methacrylic acid ester and combinations thereof; wherein the core particle contains a release trigger component and/or the coating contains a release trigger component, said release trigger component being selected from: —a water-swellable polymer having a water-uptake capacity at 37° C. and pH 7.0 of less than 20 wt. % and a water-uptake capacity at 37° C. and pH 2.0 of at least 50 wt. %; an—an edible salt having a water solubility at 37° C. and a pH of 7.0 of less than 1 mg/ml and a water solubility at 37° C. and a pH of 2.0 of at least 5 mg/ml; The microencapsulate of the present invention does not release the encapsulated active component when incorporated in water-containing foodstuffs, beverages, nutritional compositions or pharmaceutical compositions. Following ingestion, however, the active component is released rapidly.
Abstract:
The present invention relates to a process for the preparation of powdered oils and more particularly to oil encapsulated in a protein containing matrix. In addition, the present invention relates to the powdered oils obtainable by such a process, and the use of these products in the preparation of food compositions, and preferably animal food compositions, such as ruminant food compositions.
Abstract:
The present invention provides a dry mixture in particulate form containing a gas release agent, a flavor component and a hydrocolloid. Upon dissolution in water, gas bubbles are released into the continuous liquid phase, and these bubbles remain dispersed in the continuous liquid phase. These dry mixes can be used for preparation of ice cream and/or desserts and/or milk shakes.
Abstract:
The present invention relates to a method for encapsulation of an edible oil using whey protein and a reducing sugar. The edible oil comprises long chain polyunsaturated fatty acids. Also compositions comprising an edible oil obtainable by the method of the invention are provided. The compositions of the invention have good stability to oxidation, good taste and/or odor, and limited diffusion from and into the continuous phase when applied in liquids. The compositions of the invention are particularly suitable for food and pharma applications.
Abstract:
The invention pertains to an encapsulation system; in particular a 3-phase system comprising an inner, second and outer phase wherein the second phase is gaseous, and wherein the 3-phase system has a lifetime of at least 3 min and the second phase has a diameter of less than 1 mm. An example of such a system is a stable, small antibubble. Also, the invention pertains to methods of making such 3-phase systems, and to use and methods of use thereof. In particular, 3-phase systems according to the invention are stabilized by surface active particles or molecules, such as for instance colloidal particles. The 3-phase systems of the invention can include a variety of other compounds, and can among others be used in pharmaceutical- or food-based applications. In particular, a 3-phase system according to the invention, such as for example an antibubble, may deliver pharmaceutical compounds.
Abstract:
Method for spray drying a high-viscosity fluid product using a spraying device, wherein the method comprises projecting the fluid product out of an outflow opening of the spraying device for obtaining droplets of the fluid product, wherein the spraying device is arranged to cause a pressure drop in the fluid product across the outflow opening which is larger than 15 bar and at least partially drying the droplets in a drying medium, such as air, to become particles.
