“…The water evaporation rates observed in the spray-drying process is most likely the reason of morphological irregularities that have appeared on the surface of the microparticles. Lower inlet temperature of spray-drying process resulted in irregular microparticle form with shrunk, concave surfaces, while higher inlet temperature resulted in smoother, tighter microparticles [20,40].…”

Spray-drying is the most popular encapsulation method used for the stabilization and protection of biologically active compounds from various environmental conditions, such as oxidation, moisture, pH, and temperature. Spray-drying increases the bioavailability of the natural active compounds and improves the solubility of low-soluble compounds. The aim of this work was to study the effects of different wall materials and optimize wall material solution’s composition on physicochemical properties of microcapsules loaded with phenolics, extract rich in volatile compounds and essential oil from Elsholtzia ciliata herb. For encapsulation of elsholtzia and dehydroelsholtzia ketones, more suitable wall materials were used—beta-cyclodextrin and sodium caseinate. Four phenolics—sodium caseinate, skim milk, beta-cyclodextrin, and resistant-maltodextrin—were used. A D-optimal mixture composition design was used to evaluate the effect of wall material solution’s composition using sodium caseinate (0.5–1 g), skim milk (6–10 g), resistant-maltodextrin (8–12 g), and beta-cyclodextrin (0.5–1 g) for the encapsulation efficiency, drying yield, and physicochemical properties. The optimal mixture composition was 0.54 g of sodium caseinate, 10 g of skim milk, 8.96 g of resistant-maltodextrin, and 0.5 g of beta-cyclodextrin. These encapsulating agents had a good performance in the microencapsulation of E. ciliata ethanolic extracts by the spray-drying technique. It is proven that the produced microparticles have a good potential to be included in various pharmaceutical forms or food supplements.

Macaranga is a genus of the family Euphorbiaceae which comprises of about three hundred species. It is present in some parts of the world which include Indonesia, some parts of Africa, Madagascar, Asia, the east coast of Australia and the Pacific islands. 7-15 The Macaranga gigantea plants are known to be in the form of shrubs or trees and grow in places with optimum sunlight, secondary forests or forests that have been destroyed. Macaranga gigantea plants show several bioactivity which include antitumor, anticancer, antimalaria, antimicrobes, ABSTRACT Introduction: The aim of this research was to formulate the microcapsules of Macaranga gigantea leaves extract with solvent evaporation method using Ethocel 10 cP and Eudragit E100 as matrix. Methods: M. gigantea leaves were extracted using ethanol 96%. This extract was dried by rotary evaporator. The microencapsulation process of M. gigantea leaves extract was conducted by solvent evaporation method (O/W: oil in water). The formula of M. gigantea leaves extract microcapsules were designed into six formulas (Eudragit E100: FA 1 , FA 2 , FA 3 and Ethocel 10 cP: FB 1 , FB 2 , FB 3). Microcapsules of M. gigantea leaves extract were characterized for particle size, in terms of surface morphology by scanning electron microscope (SEM) and encapsulation efficiency. Antioxidant activity of the formulation have been evaluated by DPPH method. Physical characterization on microparticles were performed by conducting entrapment efficiency and SEM picture. Results: In this research, the micoparticles containing M. gigantea extract has been developed by using ethyl cellulose (Ethocel 10 cP) and eudragit (Eudragit E100) as polymer matrix. The results showed that high concentration of polymer (Ethocel 10 cP and Eudragit E100) used in microencapsulation resulted in better M. gigantea leaves extract microcapsules in terms of physical characteristics. Particle size of microcapsules containing M. gigantea leaves extract were in the range of 3.564 to 5.887 μm. Encapsulation efficiency (% EE) was categorized as good because the value were ≥ 80% to which 85.978% (FA 3) and 88.992% (FB 3). SEM picture of FA 3 (Eudragit E100) revealed that the surface of microcapsule were rough and porous. When Ethocel 10 cP used as polymer, a smoother surface and less visible pores of microcapsule were obtained. The antioxidant ability of M. gigantea leaves extract microcapsule showed that IC 50 values was 64.51 ppm. Conclusion: It can be concluded that microcapsules of M. gigantea leaves extract can be prepared by solvent evaporation method by using Eudragit E100 and Ethocel 10 cP as polymer matrix. M. gigantea leaves has potent antioxidant activity either as extract or after formulated into microcapsules.

Microencapsulation is a widely‐investigated technique used for the unstable material preservation since the wall materials prevent the core materials from loss and deterioration. To improve the stability of cinnamaldehyde (CAL), different microcapsule wall systems are fabricated by spray‐drying, and then characterized by experimental methods to determine the most suitable wall materials. Surface morphology, encapsulation efficiency, effective loading capacity, as well as moisture absorption property are evaluated, and the results suggest that a three‐matrix system of methyl cellulose (MC)/sodium alginate (SA)/MC or MC/carboxymethyl chitosan (CMC)/SA wall formulation is more suitable for CAL microencapsulation. Moreover, a novel quantitative method is also proposed to verify the most stable wall material microencapsulation. The quantitative results show that the highest activation energy (53.00 ± 2.24 kJ/mol) is observed for the MC/CMC/SA‐encapsulated CAL microcapsule. Taken together, the results suggest that MC/CMC/SA wall formulation shows excellent barrier properties and is superior to other wall materials in preventing microencapsulated CAL deterioration. This study will be efficient in designing an ideal capsule for CAL microencapsulation.
