Kinetic Study of the Specific Migration of an Organotin Heat Stabilizer from Rigid Poly(vinyl chloride) into Food Simulants by FTIR Spectroscopy

Abstract

The aim of this paper is the determination of the specific migration of an organotin heat stabilizer (Irgastab 17 MOK) from rigid poly(vinyl chloride) (PVC) into food simulants. For that purpose, two fatty simulants were used: hexane and ethanol. The test conditions were 15 d at 4 and 40 C and 3 h at 70 C. The rate of the mass loss of the films was followed as a function of time. FTIR spectroscopy was used to investigate the migration phenomena and to estimate the diffusion coefficients and the activation energy of diffusion by using mathematical models. The influence of various parameters such as temperature, time of contact and the nature of food simulant was considered. The results show that FTIR spectroscopy is a simple, low cost and rapid method which can be used to investigate the migration phenomena.

Specific migration of IRGASTAB 17 MOK and DBP from rigid and plasticized poly(vinyl chloride) into organic liquids

“…It can be observed that the additive migration is related to the temperature. As it is mentioned in the literature, the migration is more important at higher temperatures [11][12][13][14]. It is obvious that the mobility of the migrant molecules increases with enhancement temperature, since the highest migration is obtained at 70 °C.…”

“…Therefore, the real migration of DBP would be hidden in hexane. The presence of the plasticizer in films accelerates heat stabilizer migration [9,11,12,14], obtained rates migration were 2.25 times higher than rigid films FR 4.5 .…”

Determination of mechanical properties of whey protein films during accelerated aging: Application of FTIR profiles and chemometric tools

“…Consequently, spectrometric techniques, a branch of vibrational techniques, as Fourier Transform Infrared (FTIR), and Near-infrared (NIR) have presented an alternative for the non-destructive determination of different quality parameters in the food industry. Some examples are the reported by Mauricio-Iglesias, Guillard, Gontard, and Peyron (2009) in his study over diffusivity of additive Uvitex OB in Linear Low Density Polyethylene; Zeddam and Belhaneche-Bensemra (2010) to know the migration phenomena of additive Irgastab 17 MOK in a plastic material; Rohman, Che Man, Hashim, and Ismail (2011) to detect, quantify and analyze and the presence of lard in vegetable oils; Branca et al (2016) to study intramolecular components of chitosan films under different conditions; Nunes, Andrade, Santos Filho, Lasmar, and Sena (2016) to detect and characterize adulterated beef; Guo and Wu (2018) to study the water adsorption in cellulose film; Sánchez et al (2018) to predict dry matter content, texture, and color of spinach leaves; Vásquez et al (2018) study the cheese texture during the ripening; Nallan Chakravartula, Cevoli, Balestra, Fabbri, and Dalla Rosa (2019) to evaluate a predictive model for estimate drying time in edible coating on bread, and to study the mechanical properties of tea plucking machine and tea stem (Du, Hu, & Buttar, 2020). FTIR, as another vibrational technique, requires to be coupled to chemometrics methods for the resolution and interpretation of complex spectroscopic data profiles.…”

Reduction of the Additives Migration from Poly Vinyl Chloride Films by the Use of Permanent Plasticizers

“…There have been many studies on the phenomenon of migration (Marin, Lopez, Sanchez, Vilaplana, & Jimenez, 1998;Belhaneche-Bensemra, Zeddam, & Ouahmed, 2002;Earls, Axord, & Braybrook, 2003;Marcilla, Garcia, & Garcia-Quesada, 2004, 2007Wang & Storm, 2005;Atek & Belhaneche-Bensemra, 2005;Boussoum, Atek, & Belhaneche-Bensemra, 2006;Ito, Sechimi, Miura, Kawagushi, Saito, & Nakazawa, 2006;Zeddam & Belhaneche-Bensemra, 2010;Atek, Belhaneche-Bensemra, & Turki, 2010), but few on reducing it. Various methods have been proposed to reduce the migration of plasticizers and other additives from plastic food packaging materials (Rahman & Brazel, 2004):…”
