Chemical Testing for Indirect Food Additives in Paper Products

Sunday, April 4th, 2004

Chemical Testing for Indirect Food Additives in Paper ProductsPaper products are used every day for packaging foods in a variety of applications. Paper plates, cups, cartons, wrappers, and boxes come in contact with food during storage, preparation, and service activities. For example, when you purchase a Chicken-Pot-Pie from the grocery store frozen section, paper containers are used to store the food, prepare the food in the microwave, and serve the food. All of these activities have the potential that materials present in the paper product could be transferred to the food.

Because of this potential, paper products are tested for:

• Food and Drug Administration (FDA) Regulations
• Manufacturing Quality Control for Consumer Product Health and Safety Program
• End-User or Customer Specifications

Polybrominated Diphenyl Ethers by LVI-GC/MS-SIM

Sunday, April 4th, 2004

Polybrominated Diphenyl Ethers by LVI-GC/MS-SIMColumbia Analytical Services, Inc. (CAS) now offers the analysis of Polybrominated Diphenyl Ethers (PBDEs), a class of brominated flameretardants that have been used over the past 30 years in textiles, high impact plastics and electronic circuitry. Recently, they have gained increased attention as “emergent chemicals” because of their persistence in the environment, potential for bioaccumulation, and toxicity. PBDEs are similar in structure to PCB’s, dioxins and furans.
