The authors have previously demonstrated that apricot sulfurization workers develop asthma-like syndrome during apricot sulfurization due to exposure to sulfur dioxide (SO(2)) gas. The aim of the current study was to demonstrate if exposure to SO(2) gas had any chronic effects on pulmonary functions and bronchial reactivity of the workers. Twenty-five apricot sulfurization workers and a control group were included in the study. Physical examination, skin prick tests, pulmonary function tests (PFTs), and bronchoprovocation tests (BPTs) were performed before and after the season of sulfurization in the worker group. Skin prick tests, PFTs, and BPTs were performed also in the control group without a history of exposure to SO(2) gas. There was no statistically significant difference between PFT and BPT results of the workers and the control group. Comparison of the PFT results of the workers before and after the season of apricot sulfurization neither reveal a significant difference. Four (16%) out of 25 workers were positive for BPTs before the period. Only one worker who had a negative BPT result before the sulfurization season was positive afterwards. The lack of a chronic effect on pulmonary functions is consistent with the diagnosis of asthma-like syndrome in apricot sulfurization workers.

Due to its antioxidant and antimicrobial properties, sulfur dioxide (SO) is widely used in foods and beverages to prevent the growth of microorganisms and to preserve the color and flavor of fruits. However, the amount of SO used in fruit preservation should be limited due to its possible adverse effects on human health. The present study was designed to investigate the effects of different SO concentrations in apricot diets on rat testes.

Apricot pomace (AP) is lignocellulosic agro-industrial waste that could be considered a good source for cellulose-based, value-added compounds. In this study, conditions for cellulose nanocrystals' (CNCs) extraction from apricot pomace (AP) were optimized using Response Surface Methodology (RSM) based on the extraction yield, and the resulting CNC was characterized using Fourier transform infrared (FTIR) spectroscopy, Scanning Electron Microscopy (SEM), Transmittance Electron Microscopy (TEM), Thermogravimetric Analysis (TGA), and X-Ray Diffraction (XRD). The maximum CNC yield (34.

Quality characteristics of sulphured and non-sulphured apricots dried with a sequential combined pilot scale solar assisted hot air and hot air assisted radio frequency dryer and conventional sun system were compared. The combined drying approach showed improved color, hardness, antioxidant activity and retention of vitamin C, β-carotene and total phenolic content values compared to conventional sun drying both for sulphured and non-sulphured samples. The effects of sulphur concentration and addition of pistachio hull extract as a treatment prior to drying were also investigated.

Prunus armeniaca leaf extract was screened for antibacterial compounds by high-performance thin-layer chromatography (HPTLC)-direct bioautography using a Gram-positive Bacillus subtilis bacterium. Six chromatographic zones exhibited characteristic bioactivity. Five of them also appeared after derivatization with vanillin-sulfuric acid reagent and could be characterized with HPTLC-electrospray ionization (ESI)-mass spectrometry (MS), suggesting the presence of triterpenoids and the fatty acids linolenic and palmitic acid.

The sulfuric acid-based alkylation process, which leads the industrial application market, still struggles with effectively removing a large number of organic pollutants from hazardous spent sulfuric acid. A synergistic advanced oxidation process was constructed to degrade the organic pollutants with HO and sodium persulfate as the synergistic oxidants and apricot shell-derived biochar (OBC) as the catalyst. Taking the total organic carbon (TOC) and the color scale as the indices, the effects of critical experimental factors, , reaction temperature, initial oxidant concentration, catalyst dosage, and aeration rate, were optimized.
