“…NQs and NBs presented an amorphous XRD pattern that was similar to inulin, and these patterns coincided well with previous studies [ 51 , 52 ]. Although quercetin is reported to have a crystalline structure, its addition to the NBs improves the amorphous phase by incrementing the intensity of the signals, with this being due to the chemical interaction between both compounds [ 36 ].…”

Quercetin is a bioactive component that is capable of having therapeutic potential in the prevention of different noncommunicable chronic diseases (NCDs). However, it presents instability in the gastrointestinal tract in addition to low bioavailability. One way to overcome the limitations of quercetin lies in using nanotechnology for the development of nanoparticles, based on biopolymers, that are capable of being ingestible. Inulin, a fructan-type polysaccharide, acts as a delivery system for the release of quercetin in a target cell, guaranteeing the stability of the molecule. Inulin-coated quercetin nanoparticles were synthesized by the spray dryer method, and four variables were evaluated, namely inulin concentration (5–10% w/v), feed temperature (40–60 °C), inlet temperature (100–200 °C) and outlet temperature (60–100 °C). The optimal conditions were obtained at 10% w/v inulin concentration, with 45 °C feed temperature, 120 °C inlet temperature and 60 °C outlet temperature, and the nanoparticle size was 289.75 ± 16.3 nm in water. Fluorescence microscopy indicated quercetin loading in the inulin nanoparticles, with an encapsulation efficiency of approximately 73.33 ± 7.86%. Inulin-coated quercetin nanoparticles presented effects of inhibition in Caco-2 and HepG2 cells, but not in HDFa cells. The experimental data showed the potential of inulin nanoparticles as transport materials for unstable molecules, in oral administration systems, for the encapsulation, protection and release of quercetin.

“…The nano effect of nanoemulsions makes it have high permeability which could easily reach into the cell and bind to DNA or/and enzymes, thus accelerating the death of bacteria. The results verified that the tea oil nanoemulsion with broad spectrum bacteriostatic properties could be used as a multi-functional food ingredient [29][30][31][32].…”

Application of tea oil in food products has been gained more and more attention for its nutritional advantages and functional properties. This research fabricated green tea seed oil nanoemulsions by the self-emulsification method through variation of oil and surfactant composition. Finally, in vitro antibacterial assay and antioxidant properties were investigated. The results showed that the sizes could be regulated through surfactant content (5-15 wt%) and composition (HLB 10.72-13.93) from 16.44 ± 0.01 nm to 329 ± 4.74 nm. With the increase of the content of green tea seed oil, the DPPH and total antioxidant capacity of the nanoemulsions were gradually improved. Meanwhile, the antibacterial assay was enhanced as the content of green tea seed oil increased from 0.5 to 1.5%. The inhibition zone increased continually to 7.56 ± 0.40 mm and 6.85 ± 0.59 mm when 1.5% oil was provided. The results could provide a reference to essential oils in the design of functional food-grade ingredients.
