Healthy, pure, and fresh food is one of the essential necessities for human health. For this reason monitoring is of primary importance. One possible source of contamination is the packaging that envelopes about the totality of the food consumed nowadays. Packaging for food is intended to be a food protection from external environment with the objective to supply safe, fresh, and contaminant-free food to the consumers. Food packaging legislation aims to ensure that this objective is achieved establishing the maximum quantity of chemicals transferred from the packaging into the food.
It has been demonstrated that a number of substances, considered indirect food additives, migrate from packaging into the food. Food packaging legislation regulates the control of such contaminants, among which particular attention has to be paid to residual solvents.
The preferred analytical technique for the determination of residual solvents in food packaging is gas chromatography coupled to different extraction systems. Among those, Static Headspace is certanly the most popular for its simplicity and for its capability of providing quantitative data in a short time and responding to the industry production needs.
