Special Issue Information

Dear Colleagues,

This Special Issue, “Harmful Substances in Plant-based Food”, is focused on toxic substances of various origin occuring in plant-based food and their impact on human health. This topic is very important, as vegan-like diets have become very popular and increasingly more people have decided to go vegan for ethical, environmental or health reasons. These diets eliminate all animal products and include only food which is derived from plants, including whole grains, fruits, vegetables, legumes, nuts, and seeds. If followed properly, a plant-based diet has significant health benefits and can be successful in the prevention of many illnesses, including heart disease, hypertension, diabetes, digestive disease, colon and breast cancers, and obesity. Nevertheless, a diet based exclusively on plant foods may be the source of natural toxic substances named phytotoxins and, in some cases, may increase the risk of nutrient deficiencies. Nutrient deficiency frequently results from the removal of elements of plants' yield or insufficient fertilization. On the other hand, some harmful contaminants can be introduced to plants as a result of environmental pollution. Finally, some harmful substances are formed during the processing of raw plant material.

In general, food toxins can not be removed from foods and others may be created during processing or cooking, meaning that the consumption of small quantities of food toxins is unavoidable. However, the low incidence of adverse reactions to such food is the result of setting limits on certain substances and developing mitigation procedures for process-induced toxins. However, the risk of toxicity due to the consumption of food toxins is growing in the case of increased contamination of food, overconsumption, allergies or an unpredictable idiosyncratic response.

In conclusion, in this Special Issue, articles (original research papers, perspectives, hypotheses, opinions, reviews, modeling approaches, and methods) that focus on the toxicological and regulatory aspects of toxins present in commonly consumed plant-origin foods are most welcome. Papers which illustrate the potential health risk posed by these food toxins when consumed at concentrations normally present and which discuss the possible steps which could be taken by regulators to mitigate exposure where possible are also strongly encouraged.

Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Plants is an international peer-reviewed open access semimonthly journal published by MDPI.

The indiscriminate use of pesticides in agricultural commodities has become a global health concern. Various household methods are employed to remove pesticide residues from agricultural commodities, e.g., water and ozone. Many ozone-based commercial pesticide removal machines are available in the market for the general public. The current study compares the pesticide removal efficiency of ozone-based washing of fruits and vegetables to simple tap water through commercially available machines and its health risk assessment to different age groups of consumers. The okra and green chili fruits were treated with acetamiprid and ethion as foliar application at the fruiting stage, using the recommended dose (RD) and double to the recommended dose (2RD), respectively. A modified QuEChERS-based pesticide extraction method was verified for its accuracy, precision, linearity, and sensitivity. The treated samples were washed with tap and ozonated water at different intervals, i.e., 3, 8, and 10 min using a commercial food purifier. Washing with ozonized water for 3 min recorded the maximum removal of acetamiprid and ethion from okra and chili fruits. Further, the risk quotient values (RQ) obtained were lower than one at both doses. Thus, washing vegetables with ozonized water for 3 min ensures vegetables are safer for general consumption without any health risk to Indian consumers. Full article
