Abstract:
A preparation of microspheres comprises a multiplicity of discrete microspheres, in which the microspheres comprise iron entrapped within a protein matrix, and in which the protein in the protein matrix is at least partially denatured. The protein of the protein matrix comprises denatured, de-calcified, whey protein. Methods for making the preparation of microspheres are also described.
Abstract:
A cold-gelated mono-nuclear microencapsulate comprises a unitary liquid core encapsulated within a gastro-resistant, ileal-sensitive, polymerized denatured protein membrane shell, wherein the liquid core comprises a GLP-1 release stimulating agent in a substantially solubilised form. The GLP-1 release stimulating agent is a native protein selected from native dairy protein, native vegetable protein or native egg protein.
Abstract:
Food, beverage and nutritional supplements containing microparticles containing stabilised CBD oil, and methods for the production thereof" Food, beverage and nutritional supplements that containing microparticles are described. The microparticles contain CBD oil stabilized in an acacia or inulin fibre or cyclodextrin matrix. Methods for the production of the compositions comprise making the microparticles by providing an oil-in-water microemulsion comprising CBD oil, water, acacia/inulin fibre and optionally maltodextrin or cyclodextrin, and freeze- drying the microemulsion to remove water and provide a preparation of dried microparticles. The dried microparticles comprise a dispersed phase of stabilized microdroplets of CBD oil disposed in a continuous solid matrix comprising acacia or inulin fibre. The preparation of microcapsules contains less than 10% free CBD oil and exbibit improved pharmacokinetics and bioavailability of CBD.
Abstract:
A method of producing coated microcapsules comprises the steps of producing microcapsules by cold gelation having a denatured or hydrolysed protein matrix and an active agent contained within the matrix, and drying the microcapsules. A meltable coating composition comprising wax and oil and configured to have a melting point of about 70°C to about 100°Cis heated to a temperature above the melting point of the meltable coating composition to melt the meltable coating composition, and the microcapsules are coated with the melted meltable coating composition.
Abstract:
"Microcapsules containing curcumin, and methods for the production thereof" A microcapsule suitable for delivery intact to the mammalian lower intestine via an oral route and having curcumin homogenously distributed in pockets within a crosslinked functional matrix, in which the microcapsule comprises at least 30% curcumin (w/w). Matrices formed of pea protein or Shellac have been proposed, using both spray-drying and cold gelation methods. Microcapsules of the invention are resistant to degradation in the stomach and release curcumin slowly in the ileum, and exhibit improved resistance of encapsulated curcumin to thermal and high/low pH environments.
Abstract:
A process for producing microencapsulates comprising an active component such as creatine encapsulated within a polymerised hydro lysed whey protein matrix is described. The method comprises the steps of providing a suspension of hydro lysed whey protein and an active component in a carboxylic ester, treating the suspension to generate droplets of the suspension, and immediately curing the droplets by immersion in a basic curing solution, wherein the ester in the suspension reacts with the basic curing solution to release a salt that polymerises the hydrolysed whey protein encapsulating the active component in the presence of black pepper extract, glycerol, phosphate and optionally, astaxanthin and alpha lipoic acid.
Abstract:
The invention provides a gelated mono-nuclear microencapsulate comprising a lipid emulsion core encapsulated within a gastro-resistant, ileal sensitive, polymerized chitosan membrane shell, wherein the lipid emulsion core comprises denatured or hydrolysed protein and carbohydrate. In one embodiment of the invention, the emulsion is a micro-emulsion, and typically comprises a surfactant and a co-surfactant or at least two carbohydrates, for example sucrose and a maltodextrin. In one embodiment of the invention, the lipid is a marine derived lipid such as fish oil, krill oil, or nutraceutical fatty acids. In other embodiment, the lipid is a fatty acid such as DHA or ARA, or a lipid derived from seeds, nuts or eggs.
Abstract:
A method of producing microparticles by spray drying comprises the steps of providing a spray-drying feedstock solution comprising water, a volatile divalent metal salt, weak acid, 5- 15% dairy or vegetable protein (w/v) and 1-20% active agent (w/v). The feedstock solution is adjusted to have a pH at which the volatile divalent metal salt is substantially insoluble. The feedstock solution is then spray-dried at an elevated temperature to provide atomised droplets, whereby the volatile divalent metal salt disassociates at the elevated temperature to release divalent metal ions which crosslink and aggregate the protein in the atomised droplets to produce microparticles having a crosslinked aggregated protein matrix and active agent dispersed throughout the matrix.
Abstract:
A method of producing a denatured pea protein solution comprises the steps of mixing pea protein with an alkali solvent to provide a 1-10% pea protein solution (w/v) having a pH of at least 10, resting the pea protein solution for at least 15 minutes, heating the pea protein solution under conditions sufficient to heat-denature the pea protein without causing gelation of the pea protein solution, and rapidly cooling the denatured pea protein solution to prevent gelation, wherein at least 90% of the pea protein in the denatured pea protein solution is soluble. Also described is a method of producing microparticles having a denatured pea protein matrix, the method comprising the steps of providing a denatured pea protein solution according to the invention, treating the denatured pea protein solution to form microdroplets; and cross-linking and chelating the droplets to form microparticles.
