[Object] To provide a method of producing dried egg white capable of easily and stably obtaining dried egg white having high gel strength, and the dried egg white.

[Solving Means] In this dried egg white, a proportion of an egg white protein having a molecular weight of not less than 97,400 and not more than 340,000 is not less than 35% of a proportion of an egg white protein having a molecular weight of not less than 20,100 and not more than 340,000

A protein-rich composition can be provided from egg albumen via a process that involves diafiltering with purified water an egg albumen concentrate. Collected retentate from the diafiltration step constitutes a protein-rich composition which, on a dry basis, can include less than 1% (w/w) lipids. The composition can be spray dried to a protein isolate solid which is substantially free of sugars.

The present invention relates to an apparatus (10) for shelling eggs which includes: a casing (11) defining a shelling compartment (A) and an unloading compartment (B); a shelling device (12) housed in the shelling compartment (A) and configured to open egg shells; an unloading device (13) housed in the unloading compartment (B) and comprising at least one hopper member (14a, 14b, 14c) suitable for receiving and unloading a shelling product consisting of albumen, yolk or a mixture of albumen and yolk; a transport device (15) comprising conveyors (16, 17) configured to separately transport albumen and yolk from the shelling device (12) to the unloading device (13); sanitizing devices (18, 19a, 19b, 20, 30) housed in the casing (11) and adapted to emit ultraviolet radiation and which comprise a first sanitizing device (18) positioned to irradiate operating surfaces of the at least one hopper member (14a, 14b, 14c), to reduce a bacterial load on said operating surfaces which are surfaces that come into contact with yolk and/or albumen during the operation of the apparatus (10).
