“…The encapsulation efficiency of anthocyanins, expressed as the ratio of experimental and theoretical anthocyanins concentrations per 100, was highest at 180 °C than at 160 °C, both at 10% of fructans content. A similar behaviour was reported by Laokuldilok & Kanha (2017) and Daza et al ., which can be explained due to low residence time of the powder in the drying chamber (Daza et al ., 2017) and because at high evaporation rate was given causing early shell formation, preventing compounds migration towards to surface (Yang et al ., 2024). Additionally, no significant difference in the anthocyanin's concentration was observed for different fructans ratio.…”

“…4), since the core material is homogeneously distributed within the encapsulating matrix, being the resulting capsule a matrix capsule type. Some particles are observed as hollow capsules, which is indicative of the ballooning effect, due to the high inlet temperature, resulting in fast evaporation of the water (Yang et al ., 2024). It was evident in the sample dried at 180 °C and the lowest ratio 1:0.65 of SWJ solids to agave fructans (SWJ‐F(5)‐180), in which the biggest (3.5 ± 2.2 μm) spherical hollow microcapsules are observed.…”

SummaryThe searching of alternative products that help reduce sugar consumption is a recurring objective due to the high number of overweight people in the world. The spray drying process of natural strawberry juice (SWJ) was evaluated using Agave angustifolia fructans as an encapsulating agent. Five fructan concentrations and three drying conditions were evaluated. The microcapsules obtained were characterised by anthocyanins content (UVvis), moisture percentage, hygroscopicity, colour, Tg, morphology (light scattering and SEM) and FTIR. Considering a recovery yield above 50%, the inlet/outlet temperatures of 180/90–95 °C and 15% of fructans were the conditions to obtain the powders with a hygroscopicity of 31%, anthocyanin retention of 84% and the highest Tg (54 °C). FTIR spectra and SEM evidenced that fructans can act as a homogeneous encapsulating matrix of SWJ. Therefore A. angustifolia fructans can be an alternative of low‐caloric power for the encapsulation of SWJ through spray.

Spray‐drying is a popular and well‐known “drying tool” for engineers. This perspective highlights that, beyond this application, spray‐drying is a very interesting and powerful tool for materials chemists to enable the design of multifunctional and hybrid materials. Upon spray‐drying, the confined space of a liquid droplet is narrowed down, and its ingredients are forced together upon “falling dry.” As detailed in this article, this enables the following material formation strategies either individually or even in combination: nanoparticles and/or molecules can be assembled; precipitation reactions as well as chemical syntheses can be performed; and templated materials can be designed. Beyond this, fragile moieties can be processed, or “precursor materials” be prepared. Post‐treatment of spray‐dried objects eventually enables the next level in the design of complex materials. Using spray‐drying to design (particulate) materials comes with many advantages—but also with many challenges—all of which are outlined here. It is believed that multifunctional, hybrid materials, made via spray‐drying, enable very unique property combinations that are particularly highly promising in myriad applications—of which catalysis, diagnostics, purification, storage, and information are highlighted.
