Kenaf ( Hibiscus cannabinus L.) seed oil has been proven for its multi-pharmacological benefits; however, its poor water solubility and stability have limited its industrial applications. This study was aimed to further improve the stability of pre-developed kenaf seed oil-in-water nanoemulsions by using food-grade ternary emulsifiers. The effects of emulsifier concentration (1, 5, 10, 15% w/w), homogenisation pressure (16,000, 22,000, 28,000 psi), and homogenisation cycles (three, four, five cycles) were studied to produce high stability of kenaf seed oil-in-water nanoemulsions using high pressure homogeniser. Generally, results showed that the emulsifier concentration and homogenisation conditions had great effect ( p < 0.05) on the particle sizes, polydispersity index and hence the physical stability of nanoemulsions. Homogenisation parameters at 28,000 psi for three cycles produced the most stable homogeneous nanoemulsions that were below 130 nm, below 0.16, and above −40 mV of particle size, polydispersity index, and zeta potential, respectively. Field emission scanning electron microscopy micrograph showed that the optimised nanoemulsions had a good distribution within nano-range. The optimised nanoemulsions were proved to be physically stable for up to six weeks of storage at room temperature. The results from this study also provided valuable information in producing stable kenaf seed oil nanoemulsions for the future application in food and nutraceutical industries.

The Mean

Equal parts of sugar beet pectin and sodium caseinate were interacted through electrostatic attraction, enzymatic crosslinking, and the Maillard reaction to prepare three oil-in-water emulsifier systems. Oil-in-water emulsions (10%) were processed via high shear overhead mixing at the natural pH of the emulsifier systems, followed by pH adjustment to pH 4.5 and pH 7. The emulsions were stable against coalescence, except for a slight increase in the mean droplet size for the enzymatic cross-liked emulsion at pH 4.5 over a 14-day storage period. This emulsion also showed the lowest absolute zeta (ζ)-potential value of near 30 mV. The Maillard interaction emulsifier system resulted in larger droplet sizes compared to the other two emulsifier systems. Small deformation oscillatory shear rheology assessment of the emulsion cream phases revealed an impact of the emulsifier system design at pH 4.5.

Interfacial Behaviour

The capacity of both native (NSI) and denatured (DSI) soybean isolates to stabilise oil in water emulsions under controlled shear stress was evaluated. The effect of protein concentration, thermal treatment of proteins and salt addition were studied. Sodium caseinate (SC) was used as standard protein. Emulsions prepared with NSI and SC were stable against coalescence in the whole range of protein concentration (1-10 mg/mL) in spite of showing different interfacial behaviour. The interfacial pressure of DSI was higher than NSI, according to its high dissociation degree and aromatic surface hydrophobicity. However, the emulsions prepared with this sample were unstable in the whole range of bulk protein concentrations. When NaCl was added, higher coalescence was obtained with NSI and SC emulsions at low protein concentrations, and stabilisation was reached only by increasing protein concentrations. At high protein concentrations(>5 mg/mL), DSI emulsions were stable in presence of salt, due to the formation of rigid flocs resistant to agitation. Droplet size distribution, microstructure and flocculation tendency of droplets explained the differences in coalescence of NSI, DSI and SC emulsions.

Objective: The objective of the study was to evaluate the toxicity profile of Celastrus paniculatus (CP) by performing a preclinical study on Swiss albino mice and demonstrate a safety description through monitoring their autonomic, neurological, behavioral, physical, and biochemistry profiles. Methods: The toxicity profiles (acute and subacute) of CP were evaluated using Swiss albino mice in which they were divided into four groups: Group I received 1% Tween 20 and dimethyl sulfoxide. Group II, III, and IV received CP seed oil orally, at doses of 300, 2000, and 5000 mg/kg body weight for both acute and subacute toxicity studies in accordance with Organization for Economic Cooperation and Development guidelines No. 423. Special attention was given during the first 4 h and daily thereafter for a total of 14 days. Behavioral profile, physical state changes, and other parameters such as tremors, convulsion, lethargy were noted. Clinical signs were observed daily during the 28 days of the treatment period. Body weights were measured once a week. On the 29th day, the animals were kept to overnight and blood samples were collected through retro-orbital puncture for biochemical analysis. Results: In both acute and subacute toxicity studies, the treatment with CP did not affect the normal health status of animals. It is suggestive that CP is considered practically non-toxic. Conclusion: The toxicity profile of CP seed oil was evaluated and found to be safe until 2000 mg/kg dose.
