In Romanian ethnopharmacology, species is known for its remarkable biological activity. We present an advanced approach to encapsulation using maltodextrin matrices to enhance the stability and efficacy of phytoconstituents and nanoparticles. Two distinct carrier systems were developed: (i) a direct micro-spray encapsulation of in maltodextrin to produce a maltodextrin-encapsulated carrier (MEC), and (ii) a two-step process involving the preparation of a new phytocarrier system based on gold nanoparticles (EC-AuNPs), followed by micro-spray encapsulation in maltodextrin to create the maltodextrin-encapsulated AuNPs system (MEC-AuNPs system). Comprehensive chemical profiling using GC-MS and ESI-QTOF-MS revealed 80 bioactive molecules, including terpenoids, alkaloids, flavonoids, and phytoecdysteroids. Morpho-structural (XRD, FTIR, Raman spectroscopy, SEM) and thermal analyses confirmed the successful integration of NPs within the matrices. EC-AuNPs and MEC-AuNPs exhibited superior antioxidant activity, significant antimicrobial efficacy against major bacterial pathogens (, , , , , and ), and enhanced cytotoxicity against MCF-7 and HT-29 cancer cell lines. This study highlights the potential of combining with AuNPs and maltodextrin encapsulation to develop multifunctional therapeutic systems. The findings underscore the importance of phytoconstituent stabilization and nanotechnology in addressing global antimicrobial resistance and advancing innovative medical applications.

The study aimed to investigate the effects and properties of micro-encapsulation (Mc) of bioactive extracts from Pistacia vera hull (Pv-He) using response surface methodology (RSM) for mathematical modeling-optimization (MMO). The independent variables optimized were temperature (T:120-180 °C), extract dilution (Eks-Dl:0-4), maltodextrin/gum arabic (MDx/GA:20-80 %), and extract-to-wall blend (W-Rt:5-20 g) in spray-drying. The variables significantly influenced water activity (Wa, P < .

Prodigiosin, a microbial pigment, was produced using Serratia marcescens and encapsulated with β-cyclodextrin (BCD), maltodextrin (MD), gum Arabic (GA), and soy protein isolate (SPI) to enhance stability and bioavailability. Emulsions were prepared by dissolving wall materials (5 % w/v) in water, mixing with prodigiosin in ethanol (1:1), and adding Tween 80 as an emulsifier. The mixture was ultrasonicated, homogenized, and freeze-dried to form nanoparticles.

This study aimed to develop carotenoid and antioxidant-rich encapsulates by spray drying from industrial tomato by-products to enhance their techno-functional properties by using green extraction techniques at a pilot plant scale. Tomato pomace by-products (peels and seeds) can be a source of functional ingredients for the industry since they are nutritionally valuable compounds, mainly carotenoids. Ultrasound assisted extraction (USAE) and accelerated solvent extraction (ASE) can be highlighted as green techniques to extract key bioactive compounds.
