Due to its course, multiple myeloma may negatively affect the functioning of patients. Different treatment methods are also associated with patients' varying perception of their health condition. The purpose of this study is to determine the disease-specific complaints among multiple myeloma patients during selected treatment methods-chemotherapy, autologous hematopoietic stem cell transplantation, and supportive therapy.

The occurrence of carbonyl compounds and volatile organic compounds (VOCs) in adult formulas is a critical issue in product safety and quality. This research manuscript reports the determination of targeted and untargeted carbonyl compounds and VOCs in adult formulas stored at different temperatures (room temperature, 4 °C, and 60 °C) over one month. Gas chromatography-mass spectrometry was utilized for the sample analysis.

The EFSA Panel on Food Additives and Flavourings (FAF Panel) evaluated the safety of the extension of uses of quillaia extract (E 999) as a food additive in food supplements supplied in a solid or liquid form, excluding food supplements for infants and young children. Quillaia extract (E 999) was re-evaluated in 2019 by the EFSA FAF Panel, which derived an acceptable daily intake (ADI) of 3 mg saponins/kg bw per day for E 999, while in 2024 a follow-up of the re-evaluation was published by the FAF Panel, recommending some modifications of the existing EU specifications for quillaia extract (E 999). Currently, quillaia extract (E 999) is authorised in two food categories (FCs) i.

Article Synopsis
  • The EFSA Panel evaluated the safety of hesperetin dihydrochalcone as a new flavoring substance, determining that it did not require a read-across with other flavonoids in a previous group assessment (FGE.32).
  • The Panel found no genotoxicity concerns and anticipated that hesperetin dihydrochalcone would be metabolized to harmless products, despite lacking direct ADME studies for this substance.
  • Although a 90-day study indicated potential effects on thyroid hormone levels, these were deemed non-adverse, and exposure estimates for both adults and children showed sufficient safety margins.

This study explores the extraction of proteins from edible insects such as Tenebrio molitor, Acheta domesticus, and Locusta migratoria using alkaline extraction and acid precipitation (AEAP) as a control method and evaluates the influence of salting-in (NaCl-assisted), salting-out ((NH₄)₂SO₄), and combined salting-in/out techniques on the resulting protein quality and functional properties. We hypothesized that salt-assisted methods would enhance protein extraction efficiency and functionality compared to AEAP. Molecular size distribution analysis confirmed that the salting-out method preferentially aggregated smaller proteins (<30 kDa).
