Abstract

Biostimulant products are recognized for their ability to improve the agronomic parameters of plants and the qualitative and nutraceutical parameters of fruits and confer greater resistance to plants under abiotic and biotic stress conditions. In our study, we tested three different biostimulants on cultivar "Lady Cot" apricot plants: animal-derived protein hydrolysate, plant-derived protein hydrolysate, and one based on algae to evaluate their effects on improving the agronomic parameters of plants and fruit quality. The product that stood out for providing positive effects was the protein hydrolysate-based product, which increased plant production by 53.80% and yield efficiency by 56.38%. At the same time, it also increased the fruit's diameter growth by approximately 8.3%, showing positive effects on fruit weight as well. The animal-derived protein hydrolysate also reduced acidity by 13.8% and showed a significant increase compared to the control in terms of total polyphenols. Additional research is scheduled to validate these results and ascertain which categories of biostimulant products are most effective in enhancing the agronomic, qualitative, and sensory characteristics of other apricot cultivars.

Abstract

Mycotoxins are secondary toxic metabolites produced mainly by fungi belonging to the Aspergillus, Penicillium, Fusarium, Alternaria, and Claviceps genera. These moulds can colonize agricultural crops and produce mycotoxins during pre- and post-harvest practices, processing, and storage. Animals fed with feed contaminated with mycotoxins may be a natural and unwanted bioenhancer way to transfer mycotoxins, eventually metabolized, to animal-derived food addressed to humans. The natural occurrence of mycotoxins, also a low concentration, in food may cause adverse health effects in humans, rarely showing acute symptoms but the chronic exposure causes problems ranging from gastrointestinal and kidney disorders to immune deficiency and to develop some types of cancers. Human exposure to mycotoxins can happen by eating directly contaminated foods or through contaminated animal products. This alternative entry of mycotoxin into the human food chain is a signal of animals fed with contaminated feed. The exposure danger to mycotoxins can be monitored by following the biotransformation product occurrence in tissues and biological fluids, and these data are needed to evaluate their potential risk for humans, in particular for weak subpopulations like babies, children, old, or pressed by food security troubles. In this regard, the main aim of this volume is to evaluate the occurrence of mycotoxins and other contaminants in food, nutraceuticals, and biological fluids in order to ensure human safety. To guarantee effective consumer safety, reliable methods have been validated for the analysis of contaminants in various matrices. In addition, the risk associated with the assumption of contaminated food was assessed. Risk characterization is an indispensable aspect to safeguard public health, which helps to identify risks threatening consumers.

Abstract

Mycotoxins are a major source of contamination in cereals, posing risks to human health and causing significant economic losses to the industry. A comprehensive strategy for the analysis of 21 mycotoxins in Italian cereal grain samples (n = 200) was developed using a simple and quick sample preparation method combined with ultra-high-performance liquid chromatography coupled with quadrupole Orbitrap high-resolution mass spectrometry (UHPLC Q-Orbitrap HRMS). The proposed method showed some advantages, such as multi-mycotoxin analyses with simple sample preparation, fast determination, and high sensitivity. The analysis of the sample revealed the presence of 11 mycotoxins, with α-zearalenol being the most frequently detected, while deoxynivalenol exhibited the highest contamination level. Furthermore, co-occurrence was identified in 15.5% of the samples under analysis. Among these, 13% of the samples reported the simultaneous presence of two mycotoxins, while 2.5% showed the co-occurrence of three mycotoxins. Currently, there has been a renewed interest in guaranteeing the quality and safety of products intended for human consumption. This study holds significant value due to its ability to simultaneously detect multiple mycotoxins within a complex matrix. Furthermore, it provides findings regarding the occurrence and co-occurrence of emerging mycotoxins that currently lack regulation under the existing European Commission Regulation.

Abstract

Infant milk formulas are designed to substitute human milk when breastfeeding is unavailable. In addition to human milk and milk-derived products, these formulas can be a vehicle of contaminants. In this work, a multiclass method based on the QuEChERS (quick, easy, cheap, effective, rugged, and safe) approach was developed for the simultaneous determination of contaminants (n = 45), including mycotoxins and veterinary drug residues, occurring in infant milk formulas. By using an ultra-high-performance liquid chromatography quadrupole-Orbitrap coupled with high-resolution mass spectrometry analysis (UHPLC-Q-Orbitrap HRMS; Thermo Fisher Scientific), further retrospective analysis of 337 contaminants, including pesticides, was achieved. The method was validated in accordance with European regulations and applied for the analysis of 54 infant milk samples. Risk assessment was also performed. Dexamethasone was detected in 16.6% of samples (range: 0.905–1.131 ng/mL), and procaine benzyl penicillin in 1 sample at a concentration of 0.295 ng/mL. Zearalenone was found in 55.5% of samples (range: 0.133–0.638 ng/mL) and α-zearalenol in 16.6% of samples (range: 1.534–10.408 ng/mL). Up to 49 pesticides, 11 veterinary drug residues, and 5 mycotoxins were tentatively identified via retrospective analysis based on the mass spectral library. These findings highlight the necessity of careful evaluation of contaminants in infant formulas, considering that they are intended for a vulnerable part of the population. [ABSTRACT FROM AUTHOR]
