“…Values higher than those found in the present study, these differences can be attributed to the molecular interaction of AG with MOPN during the emulsion, making it necessary to study improvements in the process conditions to increase the efficiency of the interaction between the polysaccharides, such as a longer time of emulsion, which may favor an increase in encapsulation yield and efficiency. ther studies with Brazilian cerrado fruit oils using AG associated with gelatin as a wall material obtained a yield of 96.45% and an efficiency of 96.68% in the complex coacervation of pequi oil (Justi, Sanjinez-Argandoña, & Macedo, 2018); and 82.55 and 70.72% of yield and efficiency, respectively, for bacuri oil (Lima et al, 2019). These studies suggest that the results obtained in the present work are considered effective, since the efficiency is within the values obtained by these authors.…”

“…Many microencapsulation techniques are used to obtain encapsulated compounds, highlighting the complex coacervation process, mainly for oils, since it allows interaction, in an aqueous environment, between two oppositely charged polymers (proteins and polysaccharides) the possibility of forming, around droplets of the active material, a capsule. However, the efficiency of the process depends on factors such as the pH of the environment, system turbulence, emulsion droplet size, process temperature, ionic strength, wall material, the latter being one of the most relevant (Lima et al, 2019;Timilsena, Okanbi, Khalid, Adhikari, & Barrow, 2019).…”

Innovative materials for the encapsulation of bioactive compounds are a permanent challenge. In this sense, the purpose of the study was to evaluate the use of Ora-pro-nobis mucilage (MOPN) as a wall material to replace Arabic gum (AG), in microencapsulation by complex coacervation of bocaiuva (Acrocomia aculeata) pulp oil. The MOPN was obtained from green leaves, and the pH, color, water activity, humidity, fixed mineral residue, proteins, lipids, and extraction effectiveness were determined. MOPN was employed as a partial or total replacement of AG in the microencapsulation of bocaiuva pulp oil. Dehydrated and wet mucilages were used to emulsion formation. The interaction between biopolymers, the effectiveness, efficiency of microencapsulation, and the morphological characteristics of microcapsules were confirmed. In addition, the bioactive compounds (chlorophyll and β-carotene) and antioxidant activity were evaluated. The microcapsules were produced using moist mucilage. Microcapsules obtained with AG/gelatin/ bocaiuva oil were considered as control samples. MOPN showed brown color and chlorophyll content of 72.44±5.74 mg 100 g-1. The interaction between AG and MOPN in microcapsule formation was proven for the formulations with 25 and 50% MOPN substitution. The effectiveness was 74.83 and 75.22%, and encapsulation efficiency was 79.18 and 74.59%, respectively, verified through optical micrograph. In addition, the microcapsules with 25 and 50% MOPN as wall material showed three times more antioxidant activity against ABTS, and two times more β-carotene compared to the control microcapsule.
