Special Issue Information

Dear Colleagues,

With the rapid advancement of economic globalization, food safety issues have become increasingly prevalent, posing a significant threat to public health. Throughout the production, processing, and distribution of food, numerous endogenous and exogenous food safety concerns can arise. For instance, contaminants such as pesticides, veterinary drugs, heavy metals, and persistent organic pollutants may affect animals and plants as they grow. Meanwhile, the curing, roasting, and fermentation processes of meat can lead to the formation of harmful substances (such as N-dimethylnitrosamines, heterocyclic amines, acrylamides, and biogenic amines). Furthermore, due to their high protein and moisture content, many seafood products are highly susceptible to spoilage during storage and transportation. Therefore, the development of innovative sample pre-treatment and analytical techniques is imperative to safeguard the quality and safety of food.

This Special Issue aims to invite contributions that showcase the latest advancements in technologies applied to the extraction and purification of chemical contaminants in food, as well as innovative detection methods used for the analysis of food quality and safety. Topics of interest for this Special Issue include, but are not limited to, the following:

  1. Metal and covalent organic frameworks surrounding materials;
  2. Solid-phase extraction techniques;
  3. QuEChERS methods;
  4. Spectroscopy techniques;
  5. Nanomaterial-based sensors;
  6. Electrochemical detection techniques;
  7. Chromatographic techniques.

Within the realm of archaeology, the analysis of biomolecules assumes significant importance in elucidating historical dietary patterns and their implications for contemporary contexts. To achieve this, knowledge and tools of both chemistry and archaeology are essential to yield objective outcomes and conduct analyses of archaeological materials for the detection of biomolecules. Usually, only minuscule remnants of ceramic fragments are retrieved from excavations, which limits the feasibility of comprehensive laboratory analysis. This study aimed to establish a protocol for analyzing fatty acids and starch from archaeological food utensils with minimal sample quantities. Various experiments were conducted to replicate preparations that might have occurred in archaeological vessels, aiming to establish the optimal protocol. The analyses were performed using clay griddles, subjecting vegetable oil to varying temperatures for fatty acid assessment. For starch analysis, a series of experiments encompassed diverse forms of potato preparations (pulp, chuño, tortilla, carbonization, and freeze-drying) and maize (flour, tortilla, and carbonization). The verification of the experiments was confirmed by conducting identical analyses, as developed in the current study, on authentic archaeological fragments. The principal outcomes of this investigation include the successful extraction of both types of biomolecules using only 0.25 g of the sample, obtained through direct scraping from the vessel. Soxhlet extraction was identified as the most efficient strategy to recover fatty acids. Additionally, a comprehensive protocol for the identification of starch extraction was developed. This study has, for the first time, elucidated two detailed methodologies for the extraction of fatty acids and starch in scenarios in which researchers can obtain limited quantities of archaeological food utensil fragments.
