Heat-treated extended-release formulations

A preparation of particles comprising:

• 60% (w/w) to 85% (w/w) heat-treated protein;
• 5% (w/w) to 20% (w/w) pectin or carrageenan;
• 0.5% (w/w) to 1.5% (w/w) alginate;
• and
• 0.5% (w/w) to 8% (w/w) gelator,
• which particle preparation is an extended-release particle preparation in that, when the particles are incubated in a solution of simulated gastric fluid comprising 60 units/ml of pepsin at 37° C., the protein is released over a period of time that extends for at least 2 hours, and further wherein:
• at least 5% of the protein is released over a duration of 2 hours;
• and
• at least 50% of the protein is released over a duration of 6 hours.

A food, beverage, or supplement product comprising a particle preparation that releases protein in simulated gastric fluid over a period of time that extends for at least two hours so that the particle preparation is an extended-release particle preparation, wherein particles of the preparation comprise:

• 60% (w/w) to 85% (w/w) heat-treated protein;
• 5% (w/w) to 20% (w/w) pectin or carrageenan;
• 0.5% (w/w) to 1.5% (w/w) alginate;
• and
• 0.5% (w/w) to 8% (w/w) gelator,
• and further wherein the extended-release particle preparation is characterized in that, when the particles are incubated in a solution of simulated gastric fluid comprising 60 units/ml of pepsin at 37° C., the protein is released over a period of time that extends for at least 2 hours, and further wherein:
• at least 5% of the protein is released over 2 hours;
• and
• at least 50% of the protein is released over 6 hours.
