Sec.  184.1979  Whey.

    (a)(1) Whey. Whey is the liquid substance obtained by separating the 
coagulum from milk, cream, or skim milk in cheesemaking. Whey obtained 
from a procedure, in which a significant amount of lactose is converted 
to lactic acid, or from the curd formation by direct acidification of 
milk, is known as acid whey. Whey obtained from a procedure in which 
there is insignificant conversion of lactose to lactic acid is known as 
sweet whey. Sweet whey has a maximum titratable acidity of not more than 
0.16 percent, calculated as lactic acid, and an alkalinity of ash of not 
more than 225 milliliters of 0.1N hydrochloric acid per 100 grams. The 
acidity of whey, sweet or acid, may be adjusted by the addition of safe 
and suitable pH-adjusting ingredients.
    (2) Concentrated whey. Concentrated whey is the liquid substance 
obtained by the partial removal of water from whey, while leaving all 
other constituents in the same relative proportions as in whey.
    (3) Dry or dried whey. Dry or dried whey is the dry substance 
obtained by the removal of water from whey, while leaving all other 
constituents in the same relative proportions as in whey.
    (b) The ingredients meet the following specifications:
    (1) The analysis of whey, concentrated whey, and dry (dried) whey, 
on a dry product basis, based on analytical methods in the referenced 
sections of ``Official Methods of Analysis

    (i) Protein content, 10 to 15 percent--as determined by the methods 
prescribed in section 16.036 (liquid sample), entitled ``Total

prescribed in section 16.023, entitled ``Acidity (2)--Official Final 
Action'' under the heading ``Milk,'' or by an equivalent potentiometric 
method.
    (2) Limits of impurities are: Heavy metals (as lead). Not more than
