Problems solved by technology

However, the extract used here is obtained by extracting the bird's nest with hot water and removing the solid content, and it is obviously different from the enzymatic hydrolyzate of bird's nest that is used directly by enzymatically treating the whole bird's nest
In addition, regarding the effect, it is considered that there is room for improvement within the limits considered by the present inventors.

Embodiment

[0064] The present invention will be specifically described based on the following examples, but the present invention is not limited to these examples.

[0065] (1) Preparation of bird's nest samples

[0066] (1-1) Bird's nest enzymatic hydrolyzate 1

[0067] Commercially available unbleached bird's nest is pulverized with a pulverizer to obtain bird's nest powder with a 100-mesh pass (below particle size 150 μm), add about 50 times the amount (mass) of water to the bird's nest powder, and swell at 5°C for 20 hours, and then sterilized at 121°C for 15 minutes.

[0068] After cooling the obtained treatment solution, the pH was adjusted, and an enzyme containing protease (trade name "Pancleachin F", manufactured by Amano Pharmaceutical Co., Ltd.) was added in an amount of 2% by mass relative to the bird's nest powder, and reacted at 45° C. for 3 hours.

[0069] The enzyme reaction solution was adjusted to pH 7.0, then heated at 90° C. for 5 minutes to inactivate the enzym...
