There is a need to reduce allergens in milk. To do this, the milk is boiled and
then cooled, causing albumin to settle out (to be removed). (Disadvantage:
Most globulin components, which have pronounced allergic properties,
remain in the milk.)

It is proposed that calcium chloride (0.03 to 0.1% concentration) be added to
the milk (before treatment), to cause globulin fractions to settle out during
treatment. As a result, milk allergens are reduced.

Thin-walled NiCr pipes are made by drawing operations. (Disadvantage:
The pipes are easily deformed when clamped, machined, or transported.)
