to the use of sulphurous acid in any quantity or for any period of time, 

 and showed the desirability of avoiding the use of it in products 

 intended to be used for hunuin food. 



With a few exceptions, the State Food Law prohibits the use of 

 chemical preservatives in food products offered for sale in North 

 Carolina. 



The National Meat Inspection Law provides that no meat or meat- 

 food product containing any chemical preservative can be shipped 

 from one State into another, and the National Food Law is rapidly 

 preventing the use of chemical preservatives in foods in interstate 

 commerce. 



As the use of chemical preservatives in food has fallen into dis- 

 favor and has become a violation of many of the food laws of the 

 country, these preservatives are being offered to the trade under pro- 

 prietary names, or names by which their constituents are not recog- 

 nized, as "Preservaline," "Iceine," "Freezine," "Freez-Em," "Froz- 

 Em," "Fro'stine," "Refrigerine," etc. By selling them under trade or 

 proprietary names and claiming that they are harmless and contain 

 nothing the use of which in food is a violation of the law, manufac- 

 turers are not onl}^ able to continue to sell these preservatives, but to 

 sell them at a price several times greater than the market value of 

 their chemical constituents. 



Thirty-one of these proprietary preservatives have been examined, 

 and, wdthout an exception, were found to contain some one or more 

 chemical preservatives, the use of which in food is a violation of the 

 law. 



The names of those examined, the results of the examination and 

 the claims made for them by the manufacturers are given in the f ol-
