Abstract: According to one embodiment, there is provided a substrate storage apparatus including a storage unit and an exhaust unit. The storage unit includes a plurality of plates. The exhaust unit includes an exhaust passage and a wall portion. The exhaust passage communicates with an exhaust port. The wall portion intervenes between the storage unit and the exhaust passage. The wall portion includes a plurality of slit holes. The plurality of plates protrude inward from a cabinet in the storage unit. Plates among the plurality of plates are capable of mounting a substrate. The plurality of plates are arrayed in a vertical direction. The plurality of slit holes are arrayed in the vertical direction to correspond to the plurality of plates. Each of the plurality of slit holes extends in a horizontal direction and penetrates the wall portion.

Abstract: An egg white hydrolysate having a reduced sulfur smell characteristic to egg white and a production method therefor are provided. An egg white hydrolysate having a low hydrogen sulfide content and a reduced sulfur smell can be obtained through a pretreatment step of denaturing egg white by thermally treating a diluted egg white solution under conditions of a pH of 9 to 12 and a temperature of 55° C. to 90° C., the diluted egg white solution having been prepared by diluting 1 part of liquid egg white with 0.4 to 3 parts of water, and a step of performing hydrolysis with a protease.
