Sec.  178.3520  Industrial starch-modified.

    Industrial starch-modified may be safely used as a component of 
articles intended for use in producing, manufacturing, packing, 
processing, preparing, treating, packaging, transporting, or holding 
food, subject to the provisions of this section.
    (a) Industrial starch-modified is identified as follows:
    (1) A food starch-modified or starch or any combination thereof that 
has been modified by treatment with one of the reactants hereinafter 
specified, in an amount reasonably required to achieve the desired 
functional effect but in no event in excess of any limitation 
prescribed, with or without subsequent treatment as authorized in Sec.  
172.892 of this chapter.

                                          paper and paperboard intended
                                          for food packaging and as
                                          surface sizing and coating for
                                          paper and paperboard that
                                          contact food only of Types IV-
                                          A, V, VII, VIII, and IX

    (2) A starch irradiated under one of the following conditions to

reactants listed in this paragraph (a)(2):
    (i) Radiation from a sealed cobalt 60 source, maximum absorbed dose 
not to exceed 5.0 megarads.
    (ii) An electron beam source at a maximum energy of 7 million 
electron volts of ionizing radiation, maximum absorbed dose not to 
exceed 5.0 megarads.

           List of reactants                       Limitations
------------------------------------------------------------------------
Acrylamide and [2-(methacryloyloxy)      For use only as a retention aid
 ethyl]trimethylammonium methyl           and dry strength agent
 sulfate, such that the finished          employed before the sheet-

Polyoxyethylene (4) lauryl ether.

    (c) To insure safe use of the industrial starch-modified, the label 
of the food additive container shall bear the name of the additive 
``industrial starch-modified,'' and in the instance of an industrial 
starch-modified which is limited with respect to conditions of use, the 
label of the food additive container shall contain a statement of such 
limited use.
