This methodology enables fast and ecofriendly encapsulation and gives rise to additive@MOFs with physical and features equivalent to those of materials obtained by common liquid phase encapsulation processes. It could be applied to other host–guest systems, simplifying the procedures, reducing the use and waste of harmful chemicals, and approaching the conditions of interest in the industry. The characterization carried out by thermogravimetry, X-ray diffraction, N2 adsorption, and 13C NMR provided information about the presence and conformation of the additives in the MOFs. The highest encapsulation values for caffeine (37 %) and kojic acid (32 %) were obtained with MIL-53(Al). 000084689 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FSE/T43-17R 000084689 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000084689 590__ $$a2.529$$b2019 000084689 591__ $$aCHEMISTRY, INORGANIC & NUCLEAR$$b16 / 45 = 0.356$$c2019$$dQ2$$eT2 000084689 592__ $$a0.693$$b2019 000084689 593__ $$aInorganic Chemistry$$c2019$$dQ1 000084689 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000084689 700__ $$0(orcid)0000-0003-2006-1495$$aPaseta, L.$$uUniversidad de Zaragoza 000084689 700__ $$aPotier, G. 000084689 700__ $$0(orcid)0000-0001-8105-2432$$aLópez-Ram-de-Viu, P.$$uUniversidad de Zaragoza 000084689 700__ $$0(orcid)0000-0003-1512-4500$$aCoronas, J.$$uUniversidad de Zaragoza 000084689 7102_ $$15005$$2555$$aUniversidad de Zaragoza$$bDpto.
