  • Patent number: 8778439
    Abstract: Disclosed is a method of making nutritional emulsions, comprising: (A) heating and blending together an emulsifying agent having a melt point above about 25 C and oil having hydrophobic off-notes (e.g. non-encapsulated polyunsaturated fatty acid) in a weight ratio of at least about 1:15; (B) adding the heated blend to a fat, protein, and carbohydrate mixture comprising a maltodextrin (DE of about 10 or less), in a weight ratio of the maltodextrin to the oil having hydrophobic off-notes of at least about 1:2; and (C) homogenizing, and then cooling the combination below the melt point of the emulsifying agent to form a nutritional emulsion comprising from about 0.01% to about 5% by weight of process-encapsulated polyunsaturated fatty acid. The resulting nutritional emulsions effectively mask off-notes commonly associated with certain oils, e.g., polyunsaturated fatty acids, soy oil, beta-hydroxy-beta-methylbutyrate oils.

  • Publication number: 20040197380
    Abstract: The two component carbohydrate mixture of this invention utilizes a source of fructose in combination with at least one readily digestible glucose polymer source. The addition of the fructose significantly decreases the glycemic response when compared to the digestible glucose polymer alone. Additional components may be added to the simple two component carbohydrate mixture to form a carbohydrate system suitable for incorporation into an enteral nutritional. This carbohydrate system optionally incorporates nonabsorbent carbohydrates, dietary fiber and indigestible oligosaccharides. The present invention is also directed to an enteral nutritional which incorporates the two component carbohydrate mixture and less than 37% of calories from fat. Additionally, the invention is directed to a method of delivering nutrients to a person with diabetes by feeding the enteral nutritional.

  • Patent number: 6620434
    Abstract: Dosage form unit is provided to deliver one or more beneficial agents into a fluid, such as liquid enteral nutritional product. The dosage form unit includes a core containing at least one beneficial agent, preferably a marker dye, which is dispersible in the fluid. The core also contains a compatible binding agent to bind the beneficial agent together. Additional components of the core may include a plasticizer, a standard flow agent, a lubricant, additional tableting aids and at least one hydrophilic agent. A latex coating encases the core. The latex coating includes a mixture containing a substantially hydrophobic base material, preferably formed from an emulsion of cellulose acetate microspheres, which is capable of defining a matrix-type membrane, and at least one hydrophilic component being dispersible in the fluid. A dispersible beneficial agent is preferred as one of the hydrophilic components of the latex coating to allow immediate release of the beneficial agent therefrom.
