Plastic recycling is the main solution to reduce plastic waste. High-density polyethylene has not been recycled yet successfully as food contact material due amount of chemicals present in post-consumer together with its high chemical sorption capacity. The migration two HDPE milk bottles were studied both 50 % ethanol simulant and real (one type skimmed plant base beverages (soy horchata). Firstly, a headspace-solid phase extraction-gas chromatography mass spectrometry method was developed...

A wide variety of adhesives can be used to manufacture multilayer food packaging materials. Since these materials are usually in direct contact with the packed food, compounds from adhesive may migrate into it. Therefore it is important determine composition used. The main aims this work were present packaging, study their migration simulants and finally use data test a mathematical tool designed for predicting laminates containing adhesives. For purpose total 45 market samples (laminates...

Per-poly fluoroalkyl substances (PFASs) are a group of synthetic fluorine compounds used in food packaging materials to repel water and fats. This study assessed the chemical migration PFAS from different contact materials, including cardboard, recycled biopolymer, paper Teflon trays, various markets. Migration assays were conducted using Tenax® as simulant, which was optimized by subjecting it three consecutive extractions with 3 mL ethanol within an hour. The resulting combined...

A flexible multilayer with selenium nanoparticles incorporated has been used to build an antioxidant packaging. The oxidation of hazelnuts, walnuts, and potato chips was tested at laboratory scale. Hexanal released by the nuts, fatty acids study, TBARS (thiobarbituric acid reactive substances), tasting were compared study foods packaged this Finally, method in combination selected due their simplicity accuracy. It found that hazelnuts nanoSe active bags around 20% less malonaldehyde (MDA)...

Nontarget analysis of nonvolatile substances in complex samples is a very challenging task that requires powerful analytical techniques and experience analyzing such samples. An extensive study was conducted order to identify nonintentionally added (NIAS) migrating from 18 polyethylene (PE) intended be contact with food. The migration assays were performed five simulants analyzed by ultrahigh-performance liquid chromatography (UPLC) coupled an ion-mobility separation (IMS)...

The characterization and quantification of phenolic compounds in bearberry leaves were performed using hyphenated ion mobility spectroscopy (IMS) a quadrupole time-of-flight mass spectrometer. A higher identification confidence level was obtained by comparing the measured collision cross section (TWCCSN2) with predicted values machine learning algorithm. total 88 identified, including 14 arbutin derivatives, 33 hydrolyzable tannins, 6 flavanols, 26 flavonols, 9 saccharide glycosidic...

Partition and diffusion coefficients of volatile compounds in polymers have been broadly studied the literature order to provide tools necessary predict migration from packaging materials food using appropriate mathematical models. But often, are multilayer where several substrates joint by adhesive layers. Little is known about partition between adhesives used these some commonly such as paper or cardboard. All parameters will a direct effect on final compound. The objective this work was...

Annatto (Bixa orellana L.) is cultivated primarily for the extraction of bixin, a natural dye with substantial industrial importance, resulting in generation large quantities residues that remain underutilized. This study provides first in-depth characterization annatto byproducts derived through molecular distillation, highlighting their untapped potential sustainable innovation. Employing state-of-the-art techniques-HS-SPME-GC-MS volatile compounds and UPLC-MS/QTOF non-volatile ones-the...

Polyurethane adhesives are commonly used to laminate multilayer packaging materials for food. Since these in direct contact with the food, compounds could migrate from adhesive into it. For this reason, it is important identify all potential migrants and verify their migration. Ultra-high performance liquid chromatography-quadrupole time-of-flight-mass spectrometry analyses ChemSpider database polyurethane adhesives, techniques were demonstrated be very powerful useful tools purpose....

Oligomers, are, in general, unknown components of the polymer. These oligomers can migrate from polymer into food and become a non-intentionally added substance to food. In this work, ion mobility time-of-flight mass spectrometry has been used identify migrating kitchenware. The structure elucidation polyamide 6 66 was achieved through analysis accurate m/z values adducts collision cross section precursor ions together with high-energy fragmentation patterns. Additionally, method extract...
