Autoclaves – vessels for sustaining high temperatures and high pressures – are widely used across chemical and biological sciences, and are one of the more accessible pieces of equipment for synthesis of luminescent upconversion nanoparticles (UCNPs) amongst other nanomaterials. Yet, despite being crucial to nanomaterial synthesis, the details of autoclave reactors used are barely reported in the literature, leaving several key synthesis variables widely unreported, and thereby hampering the reproducibility of many synthesises. In this perspective, we discuss the safety considerations of autoclave reactors and note that autoclaves should only be used if they are (a) purchased from reputable suppliers/manufacturers and (b) have been certified compliant with relevant safety standards. Ultimately, using unsuitable autoclave equipment can pose a severe physical hazard and may breach legal workplace safety requirements. In addition, we highlight a number of parameters in autoclave synthesis that we suggest should be reported as standard in order to maximise the reproducibility of autoclave synthesis experiments. Subsequently, we discuss two case studies where a commercially available high-safety autoclave system was used to synthesise UCNPs. We also provide broader context for the physical and optical properties of UCNPs, their applications, and other UCNP synthesis methods. We hope that this perspective encourages users of autoclave synthesis, whether in nanomaterials or in broader contexts to: (a) adopt and report the use of high-safety autoclaves and (b) report the many experimental variables involved in autoclave use to enhance reproducibility and robustness of nanomaterial synthesis.

Based on the study results, this paper reports a technology to produce natural fruit and berry pastila and marmalade of improved nutritional and biological value with a long shelf life. Critical control points of product safety have been identified and scientifically substantiated. The technological process to prepare pastila and marmalade involves exposing the raw materials to high and low temperatures while maintaining certain indicators of the content of dry substances. The identification feature of marmalade products is the content of a certain type of fruit raw materials, which poses risks throughout the life cycle of product manufacturing despite the fact that the preparation and storage of the raw materials implies the temperature range from 0 °C to minus 15 °C. Problematic issues of mold occurrence have been considered. It was established that the moisture content in the product above 15 % leads to an increase in the content of mold fungi and significantly reduces its shelf life. This paper gives the results of a study to identify the preservation of vitamin C in products prepared from fresh berries and from berries subjected to freezing. It was revealed that in the process of storing the raw materials at a temperature of minus 15 °C, the amount of vitamin C in the resulting product decreased by 11.3 % compared to the product prepared from fresh raw materials. The maximum limit of the high preparation temperatures of 108 °C did not significantly affect the loss of vitamin C. Studies were conducted to determine the sugar content in products whereby a high fructose content was identified. Critical control points at all stages of production were determined, which has made it possible to choose the optimal technological modes and parameters for the safety and quality of the product

This study aimed to analyze and compare the elemental composition of different parts of cultivated Physalis alkekengi (ljoskavac): rhizome with roots, stem with leaves, fruit, and inflated calyx. Contents of twenty-one macro- and microelements were determined by inductively coupled plasma optical emission spectrometry (ICP-OES). In addition, patterns on both macro- and microelements distribution were subjected to the AHC analysis which gave different grouping of samples in sub-clusters. Generally, potassium, calcium, iron, and aluminum were the most abundant elements, but with different distribution in examined parts. High contents of iron and aluminum were detected in a stem with leaves, followed with samples of rhizome with roots and calyx, while potassium dominates in samples of calyx and stem with leaves. Edible fruits did not contain potentially toxic metals in concentration higher than permissible limits, wherein the lowest contents of lead and aluminum were detected; cadmium was under limit of quantification. Arsenic, mercury, and thallium were below the method detection limit.
