Pyrrolizidine alkaloids (PAs) are currently in the spotlight of food safety due to potential health risk that their intake may entail for consumers. Among wide variety products likely be contaminated with PAs, teas and herbal stand out because cross-contamination weeds from PA-producing plants. Accordingly, this work simulates chamomile tea samples Senecio vulgaris Echium vulgare evaluate effect brewing on PA content at different temperature (100 75 °C) time (5 10 min) conditions. The results thermal degradation study revealed PAs quite stable compounds under conditions assayed, being initial concentration variable strongly affected stability these compounds, rather than time. On other hand, it was confirmed not all effectively transferred dry material infusion during process, leading overall transfer rates between 13 ± 1 87 10%. Also, observed extraction efficiency influenced by type matrix, since were lower when migration came vulgaris. Moreover, real a cup can overestimated 2–7 times if rate is considered highlighting importance analyzing instead correctly assess exposure consumers contaminants.

What Are We Eating? Surveying the Presence of Toxic Molecules in the Food Supply Chain Using Chromatographic Approaches

Molecules, Journal Year: 2024, Volume and Issue: 29(3), P. 579 - 579

Published: Jan. 24, 2024

Consumers in developed and Western European countries are becoming more aware of the impact food on their health, they demand clear, transparent, reliable information from industry about products consume. They recognise that safety risks often due to unexpected presence contaminants throughout supply chain. Among these, mycotoxins produced by food-infecting fungi, endogenous toxins certain plants organisms, pesticides, other drugs used excessively during farming production, which lead contamination accumulation foodstuffs, main causes concern. In this context, goals review provide a comprehensive overview toxic molecules reported foodstuffs since 2020 through Rapid Alert System for Food Feed (RASFF) portal use chromatography address challenge. Overall, natural toxins, environmental pollutants, food-processing most frequently molecules, liquid gas approaches control. However, faster, simpler, powerful analytical procedures necessary cope with growing pressures chain supply.

Levels, Toxic Effects, and Risk Assessment of Pyrrolizidine Alkaloids in Foods: A Review

Foods, Journal Year: 2024, Volume and Issue: 13(4), P. 536 - 536

Published: Feb. 9, 2024

Pyrrolizidine alkaloids (PAs) are naturally occurring secondary metabolites of plants. To date, more than 660 types PAs have been identified from an estimated 6000 plants, and approximately 120 these hepatotoxic. As a result being found in spices, herbal teas, honey, milk, considered contaminants foods, posing potential risk to human health. Here, we summarize the chemical structure, toxic effects, levels, regulation different countries provide better understanding their toxicity assessment. With recent research on assessment PAs, this review also discusses challenges facing field, aiming scientific basis for PA safety

Effect of pH and temperature on tropane alkaloids within a processing strategy to provide safe infant cereal-based food

Food Research International, Journal Year: 2024, Volume and Issue: 188, P. 114439 - 114439

Published: May 6, 2024

Tropane alkaloids (TAs) are secondary metabolites from weeds that can contaminate cereals and vegetables during harvest. Due to their toxicity, the Regulation (EC) 2023/915 sets maximum levels for atropine scopolamine in cereal-based foods infants containing millet, sorghum, buckwheat or derived products. The aim of this study was evaluate effect pH temperature on stability TAs, as possible parameters thermal processing mitigate chemical hazard infant food.

A Review of Edible Wild Plants Recently Introduced into Cultivation in Spain and Their Health Benefits

International Journal of Plant Biology, Journal Year: 2025, Volume and Issue: 16(1), P. 5 - 5

Published: Jan. 3, 2025

Before the Bronze age, when agricultural practices spread throughout Iberian Peninsula, diet of native people was based on hunting, fishing, and gathering wild plants. In spite modern agriculture, popular species for medical use, food, craftwork, etc., centuries has left a detailed knowledge use many these species. Of 6176 Angiosperms to Peninsula Balearic Islands, over 200 were introduced into cultivation during Neolithic period outside Peninsula. The names 30 progenitors still popularly used as food are listed in this paper, together with their derived crops. This review focuses five collected from ancient times, namely Borago officinalis L.
