Abstract
Embodiments of the present disclosure generally relate to protein powder compositions and methods for preparing the same. In one or more embodiments, methods include coating a plurality of protein powder particles containing myoglobin with an aluminum oxide coating to form a plurality of coated particles during an atomic layer coating (ALC) process. The protein powder compositions have improved properties over the corresponding uncoated protein powder. The protein powder compositions have greater flowability, density, and a greater level of recoverability over the corresponding uncoated protein powder.
Claims20
A method of forming a protein powder composition, comprising:
- positioning a plurality of protein powder particles within a process region of a processing chamber, wherein each of the protein powder particles comprises myoglobin;
- and
- coating the plurality of protein powder particles with an aluminum oxide coating to form a plurality of coated particles during an atomic layer coating (ALC) process, wherein the ALC process comprises one or more deposition cycles, and each of the deposition cycles comprises:
- exposing the plurality of protein powder particles to an aluminum precursor;
- infiltrating the plurality of protein powder particles with the aluminum precursor via spaces between the protein powder particles;
- purging the process region to remove gaseous remnants containing the aluminum precursor;
- exposing the plurality of protein powder particles to an oxidizing agent;
- infiltrating the plurality of protein powder particles with the oxidizing agent via spaces between the protein powder particles to produce the aluminum oxide coating disposed on outer surface of each of the protein powder particles;
- and
- purging the process region to remove gaseous remnants containing the oxidizing agent.
A method of forming a protein powder composition, comprising:
- positioning a plurality of protein powder particles within a process region of a processing chamber, wherein each of the protein powder particles comprises myoglobin;
- and
- coating the plurality of protein powder particles with an aluminum oxide coating to form a plurality of coated particles during an atomic layer coating (ALC) process, wherein the plurality of coated particles has a greater flowability value than the plurality of protein powder particles, and wherein the ALC process comprises one or more deposition cycles, and each of the deposition cycles comprises:
- exposing the plurality of protein powder particles to an aluminum precursor;
- purging the process region to remove gaseous remnants containing the aluminum precursor;
- exposing the plurality of protein powder particles to an oxidizing agent;
- and
- purging the process region to remove gaseous remnants containing the oxidizing agent.
A protein powder composition, comprising:
- a plurality of coated particles, wherein each coated particles comprises:
- a protein powder particle comprising myoglobin;
- and
- a coating disposed around each of the protein powder particles, wherein the coating comprises aluminum oxide.
