Analysis of permeability of food plastic monolayers to methylethylketone (2‐butanone) with the aromatran®

Abstract

It is very important t h a t measurements o f the diffusion o f aromas and volatile substances in trace amounts (p.p.m.) through synthetic materials, such as PVC, PE and PP monolayers, be accurate and repeatable. The primary goal o f this w o r k was t o familiarize ourselves with t h e Aromatran@, a new, fully automated analytical instrument, for t h e measurement o f a ketone (2-butanone o r MEK) a t 23°C. A discussion o f results is provided, along with comments on the system's userfriendliness and t h e cost o f t h e tests.

Food Aroma Mass Transport in Metallocene Ethylene-Based Copolymers for Packaging Applications

“…The majority of these studies have focused on polyolefins since they are the most common materials used in food packaging. Permeabilities to organic aroma compounds through polyolefins have been characterized by Mohney et al (1988), Tou et al (1990), Apostopoulos and Winters (1991), Leufven and Stoellman (1992), Kobayashi et al (1995), and Doyon et al (1995). Sorption and partition of aromas between polyolefins and foods or food simulants have been determined by Kwapong and Hotchkiss (1987), Imai et al (1990), Nielsen et al (1991Nielsen et al ( , 1992, Pieper et al (1992), Johansson et al (1993), andNielsen (1994).…”
