320845 The most appropriate method of making egg albumin sol is:

1 Keep the egg in boiling water for 10 minutes. After removing the shell, transfer the yellow part of the content to \(100 \mathrm{~mL}\) of \(5 \% \mathrm{w} / \mathrm{V}\) saline solution and homogenise with a mechanical shaker.
2 Break an egg carefully and transfer the transparent part of the content to \(100 \mathrm{~mL}\) of \(5 \% \mathrm{w} / \mathrm{V}\) saline solution and stir well.
3 Keep the egg in boiling water for 10 minutes. After removing the shell, transfer the white part of the content to \(100 \mathrm{~mL}\) of \(5 \% \mathrm{w} / \mathrm{V}\) saline solution and homogenise with a mechanical shaker.
4 Break an egg carefully and transfer only the yellow part of the content to \(100 \mathrm{~mL}\) of \(5 \% \mathrm{w} / \mathrm{V}\) saline solution and stir well.
