The occurrence of tenuazonic acid (TeA), alternariol, alternariol monomethyl and tentoxin in tomato-based products was surveyed over the years 2017-2019. A total of 120 samples were collected from retail outlets and tomato-based food producers located in Northern Italy. After extraction and purification through prepacked columns, the mycotoxins were analysed using LC-MS/MS. A widespread contamination of TeA was found in tomato-based products, particularly in concentrated tomato paste. Other toxins were not detected. The incidence of TeA was 78.5%, 47.4%, 55.5%, and 76.9% in concentrated tomato paste (maximum value 5955 µg kg), tomato sauce, tomato pulp, and ketchup, respectively. The mean level was 243 ± 725 µg kg in concentrated tomato paste and below 30 µg kg in the other tomato products. The contamination varied from year to year. strains isolated from fresh tomatoes produced mainly TeA. This study provides further toxins occurrence data, useful for future risk assessments.

Background: In the realm of plant diseases, those caused by fungi and oomycetes are particularly challenging to manage, resulting in significant economic losses. There exist diverse active substances in natural products and developing them into fungicides holds great significance. At the initial phase of our research, we discovered that Syringa pinnatifolia extract demonstrates broad-spectrum inhibitory activity against phytopathogenic fungi.

Continuous cropping decreases soil nutrients and destroys microbial community structure, so the development of eco-friendly and effective biofertilizers is necessary under present conditions. In this study, the preserving microalgal strain sp. (H) was firstly selected to be combined with agroforestry waste (shell powder, straw fermentation liquid) and the agroforestry microorganism sp.

Introduction: Tomato fruit are rich in -aminobutyric acid (GABA), which lowers blood pressure and improves sleep. An increase in GABA content is important for enhancing the nutritional quality of tomato fruit.
Methods: To investigate the effects of 5-aminolevulinic acid (ALA) on fruit quality and GABA synthesis in greenhouse tomatoes, the tomato cultivar ( cv.

The ambition to utilize agricultural by-products has spotlighted tomato leaves as a promising source for plant-based proteins. High-yielding protein extractability is key for its industrial use, but previous studies reported decreased protein extractability at later stages of plant development. This study investigated the underlying factors in protein extractability through a comprehensive proteomics analysis across four plant developmental stages (vegetative, flowering, fruit-forming, mature-fruit).
