Abstract
A method and system provides for for de-oiling and extracting protein from chickpeas prior to generating chickpea protein concentrate. The method and system includes receiving a chickpea flour generated from the chickpeas, including having cortex material removed from the chickpeas and generating an ethanol mixture by mixing the chickpea flour with ethanol to remove at least a portion of the oil content from the chickpea flour. The method and system includes separating the ethanol mixture into a de-oiled chickpea flour and an ethanol recycling stream having organics from the chickpea flour absorbed therein. Therein, the method and system includes extracting a protein concentrate from the de-oiled flour.
Claims17
A method for de-oiling and extracting protein from chickpeas prior to generating chickpea protein concentrate, the method comprising:
- receiving a chickpea flour generated from a plurality of chickpeas;
- generating an ethanol mixture by mixing the chickpea flour with ethanol to remove at least a portion of the oil content from the chickpea flour while absorbing at least a portion of organics from the chickpea flour into the ethanol mixture;
- separating the ethanol mixture into a de-oiled chickpea flour and an ethanol recycling stream having the at least a portion of the organics from the chickpea flour absorbed in the ethanol recycling stream;
- and
- extracting a protein concentrate from the de-oiled flour.
A method for extracting protein from a plant-based source material the method comprising:
- milling the plant-based source material to generate a milled flour;
- generating an ethanol mixture by mixing the milled flour with ethanol;
- removing at least a portion of an oil content of the plant-based source material from the mixing of the milled flour with the ethanol;
- separating the ethanol mixture into a de-oiled flour and an ethanol recycling stream the ethanol recycling stream including the at least a portion of the oil content of the plant-based source material;
- milling the de-oiled flour to generate milled de-oiled flour;
- and
- generating a protein concentrate from the milled flour using an air classifier.
A method for removing oil from a source material and generating a protein concentrate, the method comprising:
- decorticating the source material, the source material having a protein and an oil content therein, the decorticating removing cortex material from the source material;
- creating a flour from the source material having the cortex material removed therefrom;
- generating an ethanol mixture by mixing the flour with ethanol in a mix tank;
- removing at least a portion of the oil content from the flour using the ethanol mixture in the mix tank;
- removing at least a portion of sugars from the flour using the ethanol mixture in the mix tank;
- extracting a de-oiled flour from the ethanol mixture;
- extracting at least a portion of the ethanol from the ethanol mixture, the portion of the ethanol extracted from the ethanol mixture including the oil content and the sugars removed from the flour;
- drying the de-oiled flour using at least one dryer;
- and
- extracting a protein concentrate from the de-oiled flour.
