“…The rice protein has four significant fractions: albumin (5–10%), globulin (7–17%), glutein (75–81%), and prolamine (3–6%) [ 28 ]. Gluteins are not soluble in water, which could lead to higher encapsulation efficiency, as a similar tendency has been observed by other researchers [ 23 ]. This could explain the high difference of encapsulation efficiency between 10% and 20% oil load in samples with rice protein (nearly 18%).…”

Conscious consumers have created a need for constant development of technologies and food ingredients. This study aimed to examine the properties of emulsions and spray-dried microcapsules prepared from hempseed oil by employing a combination of maltodextrin with hemp, pea, and rice protein as carrier materials. Oil content in the microcapsules was varied at two levels: 10 and 20%. Increasing oil load caused a decrease in viscosity of all samples. Consistency index of prepared emulsions was calculated according to Power Law model, with the lowest (9.2 ± 1.3 mPa·s) and highest values (68.3 ± 1.1 mPa·s) for hemp and rice protein, respectively, both at 10% oil loading. The emulsion stability ranged from 68.2 ± 0.7% to 88.1 ± 0.9%. Color characteristics of the microcapsules were defined by high L* values (from 74.65 ± 0.03 to 83.06 ± 0.03) and low a* values (−1.02 ± 0.015 to 0.12 ± 0.005), suggesting that the materials were able to coat the greenish color of the hemp seed oil acceptably. The highest encapsulation efficiency was observed in samples with rice protein, while the lowest was with hemp protein. Combination of maltodextrin and proteins had a preventive effect on the oxidative stability of hempseed oil. Oil release profile fitted well with the Higuchi model, with hempseed oil microencapsulated with pea protein–maltodextrin combination at 10% oil loading depicting lowest oil release rates and best oxidative stability.

“…Figure 1 displays SEM images of the microcapsules, which were prepared with different oil load. All microcapsules were either spherical or nearly spherical, which is a standard trait for samples prepared by spray-drying [ 23 ]. Generally, hempseed and rice samples, with a 10% oil load, had a smoother surface than samples with 20%.…”

“…There are reports of the incorporation of phenolic compounds in cheese: Deolindo et al [ 39 ] incorporated phenolic compounds from Vitis labrusca to Petit Suisse cheese, and they observed that phenolic compounds decreased during storage, probably being affected by light, temperature, pH, or enzymes. Jansen-Alves et al [ 40 ] made microcapsules containing propolis extract and added them to Minas Frescal cheese, evaluating phenolic compounds after in vitro digestion, and they determined that the bioactive compounds were stable and their release varied depending on the wall material, making it an excellent option to stably incorporate phenolic compounds in a complex food matrix. The incorporation of phenolic compounds contained in a nanoemulsion added to cheese has not been reported.…”

The objective of this study was to compare the effects of the incorporation of microcapsules or nanoemulsions with Opuntiaoligacantha on the quality of fresh cheese. Three treatments were established: Control, cheese with microcapsules (Micro), and cheese with nanoemulsion (Nano). The parameters evaluated were physicochemical (moisture, ash, fat, proteins, and pH), microbiological (mesophilic aerobic bacteria, mold–yeast, and total coliforms), functional (total phenols, flavonoids, and antioxidant capacity), and texture (hardness, elasticity, cohesion, and chewiness) during storage for 45 days at 4 °C. The results showed that adding microcapsules and nanoemulsion did not affect the physicochemical parameters of the cheese. Total coliforms decreased in all samples from the first days of storage (Control: 4.23 ± 0.12, Micro: 3.27 ± 0.02, and Nano: 2.68 ± 0.08 Log10 CFU), as well as aerobic mesophiles and mold–yeast counts. Regarding the functional properties, an increase in total phenols was observed in all treatments. The texture profile analysis showed that the addition of microcapsules and nanoemulsion influenced hardness (Control: 8.60 ± 1.12, Micro: 1.61 ± 0.31, and Nano: 3.27 ± 0.37 N). The antimicrobial effect was greater when nanoemulsions were added, while adding microcapsules influenced the antioxidant activity more positively.

“…This proposed physical encapsulation of ProE in the matrix of NPs without chemical interaction concerning the functional groups of ProE and PLGA. Though, there was a reduction in the intensity of absorption peaks which may be owing to the formation of hydrogen bonding between the phenolic OH groups of ProE and hydroxyl groups of PLGA 55. To eliminate interference or confusion of background, the spectra of PVA and trehalose were also studied.…”

BackgroundPropolis is a unique natural adhesive product collected by honeybees. It contains a diversity of bioactive compounds with reported functional properties such as antioxidants, antibacterial, antifungal, anti-inflammatory, antiviral and anticancer activity. Dental caries is a worldwide problem that caused by microbial growth usually progress from tooth enamel to the underlying pulpal tissues and root canal. This situation could be controlled by a sequence of steps to remove microorganisms and fill root canal with a suitable long-lasting root canal sealer. Unfortunately, leachable and degradation products of the currently used sealers compromised their antimicrobial activity by inflammatory modulation associated with irritation and toxicity of periapical tissues.Materials and methodsHence, propolis was selected to be designed as a natural root canal sealer due to its amazing functional properties. Moreover, its handling properties were enhanced and potentiated by its incorporation in polymeric nanoparticles (NPs). Frist, propolis was collected, extracted and analyzed for its bioactive compounds. After that, propolis-loaded NPs of PLGA (ProE-loaded NPs) were developed and fully characterized regarding physicochemical properties, in vitro release and in vitro cytotoxicity. Then, root canal sealers were fabricated and assayed for their antimicrobial activity. Both cytotoxicity and antimicrobial activity were compared to those of a model sealer; AH Plus®.ResultsThe results revealed that spherical nanoscopic NPs with narrow size distribution were obtained. ProE-loaded NPs exhibited accepted entrapment efficiency (>80) and prolonged release. In vitro cytotoxicity study confirmed the safety of ProE-loaded NPs. Also, the developed sealers showed antimicrobial activity versus bacterial strains of Enterococcus faecalis and Streptococcus mutans and antifungal activity against Candida albicans.ConclusionProE-loaded NPs could be incorporated in and represented as a root canal sealer with prolonged release and enhanced cytocompatibility as well as antimicrobial activities.
