“…Drying in this process mainly occurs through intermittent oscillations generated in the combustor, where air and fuel enter to create an explosion by the ignition of a spark plug (Figure 4h) (Kudra, 2008; Sobulska & Zbicinski, 2021b; Wu, 2019; Zbicinski, 2002). At this time, the inlet ports are closed and extremely high velocities, temperatures, and pressure waves are generated.…”

“…In some cases, carrier agents, such as MD and starch, should be incorporated to overcome the sticking problem of sugar‐rich products, increase production yield, or encapsulate active compounds. MD, derived from starch hydrolysis, is an easily digestible carbohydrate in the small intestine that may increase the glycemic index (Sobulska & Zbicinski, 2021b). Therefore, these carrier agents do not fall under the term “clean label.” In the food industry, the term “clean label” is used to describe products that do not contain additives that are typically absent in traditional cooking (Asioli et al., 2017).…”

“…The FSD process consists of three steps, namely, (a) mixing the liquid matrix (solution, paste, or puree) with flammable components (bioethanol or vegetable oil), (b) atomization, and (c) ignition and fuel combustion to produce the heat required for dehydration (Figure 4g) (Sobulska & Zbicinski, 2021b). Briefly, the feed is prepared by dissolving a liquid matrix with a flammable liquid in a thermostatic tank under continuous stirring.…”

“…The PCSD drying process is remarkably rapid, requiring only 0.01-1 s to complete, whereas CSD usually requires 10-30 s. This swift drying process makes PCSD suitable for drying highly sensitive products (Meng et al, 2016;Wu, 2019;Zbicinski, 2002). Drying in this process mainly occurs through intermittent oscillations generated in the combustor, where air and fuel enter to create an explosion by the ignition of a spark plug (Figure 4h) (Kudra, 2008;Sobulska & Zbicinski, 2021b;Wu, 2019;Zbicinski, 2002).

The contribution of dehydration to the growing market of food powders from slurry/liquid matrices is inevitable. To overcome the challenges posed by conventional drying technologies, several innovative approaches have emerged. However, industrial implementation is limited due to insufficient information on the best‐suited drying technologies for targeted products. Therefore, this review aimed to compare various conventional and emerging dehydration technologies (such as active freeze, supercritical, agitated thin‐film, and vortex chamber drying) based on their fundamental principles, potential applications, and limitations. Additionally, this article reviewed the effects of drying technologies on porosity, which greatly influence the solubility, rehydration, and stability of powder. The comparison between different drying technologies enables informed decision‐making in selecting the appropriate one. It was found that active freeze drying is effective in producing free‐flowing powders, unlike conventional freeze drying. Vortex chamber drying could be considered a viable alternative to spray drying, requiring a compact chamber than the large tower needed for spray drying. Freeze‐dried, spray freeze‐dried, and foam mat‐dried powders exhibit higher porosity than spray‐dried ones, whereas supercritical drying produces nano‐porous interconnected powders. Notably, several factors like glass transition temperature, drying technologies, particle aggregation, agglomeration, and sintering impact powder porosity. However, some binders, such as maltodextrin, sucrose, and lactose, could be applied in controlled agglomeration to enhance powder porosity. Further investigation on the effect of emerging technologies on powder properties and their commercial feasibility is required to discover their potential in liquid drying. Moreover, utilizing clean‐label drying ingredients like dietary fibers, derived from agricultural waste, presents promising opportunities.

“…The advantage of this method is a high rate of heat transfer due to the high compression and contraction forces induced by considerable fluctuations in pressure (±10 kPa) and velocity (±100 m/s) of the gases inside the combustion chamber. 36 By developing conditions of extreme turbulence inside the drying chamber and increasing the heat transfer, the drop drying time can be shortened below 1 s. As a result, it is possible to obtain high drying yields even at relatively low temperatures (<80°C). Interestingly, pulse combustion drying can be used to dry liquids of relatively high viscosity, that is, up to 16 Pas or up to 300 mPas for suspensions or solutions, respectively.…”

As the number of new drug candidates that are poorly soluble in water grows, new technologies that enable the enhancement of their solubility are needed. This is the case with amorphous solid dispersions (ASDs) that, nowadays, not only ensure the solubility, but can also be used to control the release rate of poorly soluble drugs. However, this dosage form must overcome the major disadvantage of ASDs, which is limited stability upon storage. Thus, a thorough knowledge on polymeric carriers that can enhance drug solubility while ensuring stability in the amorphous form is necessary. In this review, the state of the art in the application of Kollidon® VA 64 (copovidone) and Soluplus® (graft copolymer of polyvinyl caprolactam-polyvinyl acetate and poly(ethylene glycol) (PEG)) in the manufacturing of ASDs over the last 20 years is presented. Apart from the classical methods, namely solvent evaporation or melting, more advanced technologies such as pulse combustion drying, high-speed electrospinning and single-step 3D printing are described. It has been shown that both the dissolution rate (in vitro) and enhancement in bioavailability (in vivo) regarding poorly soluble active ingredients of natural or synthetic origin are possible using these matrix-forming polymers.
