The aim of this study was to microencapsulate an optimized extract of purple cactus pear fruit (Opuntia ficus indica), rich in phenolic compounds (PC), betacyanins (BC), and betaxanthins (BX), with antioxidant capacity (AC), by two methodologies: combined water-in-oil-in water double emulsions-spray drying (W/O/W-SP) and conventional spray drying, studying the effect of spray drying (SP) on PC and AC. Optimal extraction conditions for bioactive compounds were: 52 °C, for 30 min, using aqueous ethanol (40%) as the solvent, with a 0.85 desirability function, obtaining 17.39 ± 0.11 mg GAE/gdw (gallic acid equivalents per gram of dry weight) for PC, 0.35 mg BE/gdw (betanin equivalents per gram of dry weight) for BC, and 0.26 mg IE/gdw (indicaxanthin equivalents per gram of dry weight) for BX. The best combination of temperatures for conventional SP and W/O/W-SP was 160–80 °C obtaining the highest retention and encapsulation efficiencies for PC. For conventional SP, results were: 107% and 100% PC and AC retention efficiencies (RE-PC and RE-AC), respectively, with 97% of PC encapsulation efficiency (EE-PC), meanwhile for the W/O/W-SP results were: 78% and 103% RE-PC and RE-AC, respectively, with 70% of EE-PC. Microcapsules obtained with W/O/W-SP maintained their structure and integrity and showed a considerable reduction in globule size in the reconstituted W/O/W emulsions due to the spray drying stress. Despite having lower EE-PC than conventional SP, spray dried W/O/W emulsions seems to be a promising controlled-delivery vehicle for antioxidant compounds.

In this work, the capacity of the mucilage extracted from the cladodes of Opuntia ficus-indica (OFI) and aloe vera (AV) leaves as wall material in the microencapsulation of pink guava carotenoids using spray-drying was studied. The stability of the encapsulated carotenoids was quantified using UV–vis and HPLC/MS techniques. Likewise, the antioxidant activity (TEAC), color (CIELab), structural (FTIR) and microstructural (SEM and particle size) properties, as well as the total dietary content, of both types of mucilage microcapsules were determined. Our results show that the use of AV mucilage, compared to OFI mucilage, increased both the retention of β-carotene and the antioxidant capacity of the carotenoid microcapsules by around 14%, as well as the total carotenoid content (TCC) by around 26%, and also favors the formation of spherical-type particles (Ø ≅ 26 µm) without the apparent damage of a more uniform size and with an attractive red-yellow hue. This type of microcapsules is proposed as a convenient alternative means to incorporate guava carotenoids, a natural colorant with a high antioxidant capacity, and dietary fiber content in the manufacture of functional products, which is a topic of interest for the food, pharmaceutical, and cosmetic industries.

The aim of this work was to obtain powders of “aguamiel” (AM) (from Agave salmiana) by spray drying using maltodextrin (MD) and Arabic gum (AG) as encapsulates. Three microencapsulated powders were obtained: Powder 1 (P1, AM/MD), Powder 2 (P2, AM/AG/MD; AG:MD, 3:1) and Powder 3 (P3, AM/MD/AG; AG:MD, 1:3) from solutions with 20% (w/w) of solutes. Powders were evaluated according to their physicochemical, antioxidant, microbiological and sensory characteristics. Powders had averages of moisture content of 2.55 ± 0.24%, water activity of 0.34 ± 0.02, and particle size of 29.84 ± 1.4 μm. It was observed that the higher the concentration of Arabic gum, the darker the powders. The physicochemical and color properties of the rehydrated powders were similar to those of fresh “aguamiel”. The microbial load, during 95 days of storage, indicated no significant changes (p > 0.05) between the initial and final values in the three powders; the highest microbial load was observed in powder P3 (6.6x103 CFU/mL and 5.9x103 CFU/mL, initial and final loads, respectively). The content of phenolics in powders P1, P2 and P3 during storage were 212.40 ± 68.22, 350.51 ± 145.00, and 266.25 ± 89.93 mg Gallic acid equivalents/100 g, respectively; the antioxidant capacity was 1,207.13 ± 109.64, 1,172.17 ± 145.80, and 1,183.34 ± 65.17 mg Trolox equivalents/100 g, respectively. According to the sensory evaluation of the rehydrated powders, the better acceptance was obtained with the P3 powder, with better physicochemical and sensorial characteristics.
