  • Patent number: 8795724
    Abstract: The present invention relates to delayed release oral formulations comprising active ingredients and modified proteins used as excipients. The proteins have chemical modifications such as succmylation, deammation, glytarylation or phosphorylation which decrease the isoelectric point of the protein compared to the protein's native isoelectric point and enhance protem-protem interactions, thereby reducing solubility and swelling, and delaying release of the active ingredient when the formulation is ingested orally. Particularly, the invention relates to tablets that comprise an excipient of chemically-modified food proteins such as soy proteins or -lactoglobulm useful for delaying release of an active ingredient such as a pharmaceutical drug or a probiotic.
    Type: Grant
    Filed: June 11, 2009
    Date of Patent: August 5, 2014
    Assignee: Universite Laval

  • Publication number: 20050124062
    Abstract: A biofilm for preparing laminated tissue constructs comprising at least one milk protein forming a sheet like structure can be used to support at least one layer of cells adhered to that. The biofilm allows for a easy handling of cultured cell sheets that can be used as tissue graft. The biofilm, comprising milk proteins and at least one plasticizer, when adhered by a cell layer can form a laminated tissue construct for body tissue replacement.

  • Publication number: 20040146564
    Abstract: The present invention relates to a process of making particles for cutaneous application or oral delivery of bioactive molecules or living systems. The process can be carried out in some simple steps. The present invention further discloses a new physiological composition allowing release different nutraceutical, biological, cosmetic, cosmeceutical, or therapeutical compounds in a human, an animal, or a composition.

  • Patent number: 6511695
    Abstract: The present invention relates to a continuous process for denaturation of proteins, which comprises the steps of: a) subjecting a protein solution to a high pressure homogenizer at a pressure of about 500 to about 5000 bar, at a recirculation ranging from 0 to about 50 and at a temperature ranging from about 20° C. to about 80° C. for a period of time on the order of milliseconds, wherein the protein solution consisting of a protein fraction dispersed in water, buffer or salt solution at a concentration ranging from about 2% to about 35% w/w and at a pH adjusted between about 2.0 to about 12.0; b) concentrating the protein solution by i) evaporation, ii) ultrafiltration and sprayed dried or iii) ultrafiltration and freeze dried.
