Sustainable-Green Synthesis of Silver Nanoparticles Using Aqueous and Extracts and Their Antioxidant and Antibacterial Activities.

Silver nanoparticles (AgNPs) biosynthesized using aqueous medical plant extracts as reducing and capping agents show multiple applicability for bacterial problems. The aim of this study was to expand the boundaries on AgNPs using a novel, low-toxicity, and cost-effective alternative and green approach to the biosynthesis of metallic NPs using and aqueous extracts. The formation of AgNPs was confirmed by transmission electron microscopy (TEM), scanning electron microscopy (SEM), and energy-dispersive spectroscopy (EDS) techniques.

The effect of pre-treatment methods on the quality of dehydrated candied Japanese quince fruits during storage.

Candied quince is one of the most popular processing products of Japanese quince () in Latvia. During the storage of dehydrated fruit, the colour turns darker, thus negatively influence the overall quality and consumers' acceptability of the product. The aim of the present study was to evaluate the effectiveness of different anti-browning agents in combination with fruit blanching and soaking as a type of pre-treatment to preserve the colour of candied quince during 8-months storage.
