“…The short wetting time of date powders is due to their richness in carbohydrates that are hydrophilic molecules able to enhance wetting in contrast to hydrophobicity caused by lipids located at the particle surface of whole milk powder. Inversely to wetting, smaller particles, due to their high specific surface area, resulting in longer swelling duration as reported by M’be et al and Fournaise et al [ 10 , 121 ].…”

“…The final solubilization step corresponds to the disappearance of particle granular structure after the complete solubilization of powder [ 121 , 128 ]. To the best of our knowledge, M’be et al [ 10 ] proposed for the first time a reconstitution mechanism of grinding-induced hibiscus powder. They identified 3 steps after the eventual wetting: swelling, dispersion comprising a first rapid stage of particle dissociation, followed by fragmentation, and finally the quasi-instantaneous molecular solubilization.…”

“…The water uptake upon swelling depends on the particle structure. As demonstrated, porous particles favor the penetration of water inside the particle by capillarity leading to rapid swelling [ 10 , 132 , 134 ]. In this sense, large and porous particles, and fine particles may yield similar swelling kinetics, hence the importance of powder structure and size.…”

“…This consequently reduces the biomolecule extraction. About dispersion, M’be et al [ 10 ] evidenced the link between this step and the extraction yield. Their studies on the reconstitution of hibiscus powder reported the improvement of the anthocyanin extraction with the dispersion step.…”

“…In this context, drying and processing the calyxes into powder allows for stabilizing the hibiscus calyx and facilitating access to its health benefits by improving the bioavailability and biomolecule accessibility, provided the process is well mastered [ 10 , 11 ]. Indeed, a reduced particle yields a higher specific surface area improving the biomolecule extraction.…”

Hibiscus sabdariffa is a tropical plant with red calyxes whose anthocyanins, phenols, and antioxidant activity make it attractive to consumers both from a nutritional and medicinal standpoint. Its seasonality, perishability, and anthocyanin instability, led to the setup of stabilization methods comprising drying and powdering. However, its properties can often be altered during these stabilization processes. Treatments such as dehumidified-air-drying, infrared drying, and oven-drying, and their combination showed better quality preservation. Moreover, powder production enables superior biomolecule extractability which can be linked to a higher bioaccessibility. However, the required temperatures for powder production increase the bioactive molecules degradation leading to their antioxidant activity loss. To overcome this issue, ambient or cryogenic grinding could be an excellent method to improve the biomolecule bioavailability and accessibility if the processing steps are well mastered. To be sure to benefit from the final nutritional quality of the powder, such as the antioxidant activity of biomolecules, powders have to offer excellent reconstitutability which is linked to powder physicochemical properties and the reconstitution media. Typically, the finest powder granulometry and using an agitated low-temperature reconstitution media allow for improving anthocyanin extractability and stability. In this review, the relevant physicochemical and processing parameters influencing plant powder features from processing transformation to reconstitution will be presented with a focus on bioactive molecules and antioxidant activity preservation.
