Definition statement
This subclass/group covers:

Obtaining of protein compositions for foodstuffs, e.g. from meat, fish or sea animals, blood, eggs, hair, cereals, leguminous or other vegetable seeds, waste water, yeasts or milk.

Bulk opening of eggs and separation of yolks from whites.

Working-up of proteins for foodstuffs, e.g. by texturising using freezing, extrusion, expansion, coagulation from or in a bath; by hydrolysis using chemical agents or enzymes.

Phosphatide compositions for foodstuffs, e. g. lecithin.

Relationship between large subject matter areas

Phosphatides in oils or fats are classified in C11B.

Special rules of classification

In groups A23J 3/04-A23J 3/20, in the absence of an indication to the contrary, classification is made in the last appropriate place.

Subject matter classified in groups A23J 3/22-A23J 3/30 is also classified in groups A23J 3/04-A23J 3/20, if the nature of the protein is of interest.

Obtaining protein compositions for foodstuffs; Bulk opening of eggs and separation of yolks from whites
Special rules of classification in this group
This subclass/group covers:

Obtaining (e.g. by extraction, separation) proteins from raw materials, does not include (after)treatments such as hydrolysis, texturizing.

Working-up of proteins for foodstuffs
Special rules of classification in this group
This subclass/group covers:

(After) treatment of proteins such as texturizing, hydrolysis, does not include obtaining (e.g. extraction) of proteins.

Phosphatide compositions for foodstuffs, e.g. lecithin
Special rules of classification in this group
This subclass/group covers:

This group includes special phosphatide compounds incorporated in foodstuffs (emulsifiers per se A23L 1/035)
