Enhancing the quality of pear candies via jaggery‐based osmotic dehydration: Optimization and analysis

open access: yesFuture Postharvest and Food, Volume 2, Issue 1, Page 40-49, March 2025.
➢ Pear has a short shelf life, so a cost‐effective dehydration method using jaggery as a pretreatment was explored to extend its availability as preserved candies. ➢ The Box–Behnken design optimized immersion time, temperature, and jaggery concentration to maximize water loss and acceptability while minimizing solute gain and achieving ideal hardness. ➢

Bortezomib (BOR)‐Pegylated‐Gold Nanovector: Synthesis, Spectroscopic Evaluation and Diagnostic Tool as Galectin‐1 Biomarker

open access: yesNano Select, Volume 6, Issue 3, March 2025.
Bortezomib pegylated gold nanoparticles as diagnostic tool for Galectine‐3 biomarker. ABSTRACT In this paper, we applied an original chemical methodology in which gold salt (HAuCl4) interacts with the chemotherapeutic drug (bortezomib; i.e., BOR) by chelation and then stacked with dicarboxylic acid‐terminated polyethylene‐glycol (PEG‐diacide) as a ...
