Although swelling and leached m, become diffuse, the granules still remain as particles at, result in a maintained particle stabiliza, outer layer into the aqueous phase that gives rise to the enhanc, (Table 2). This study showed that Pickering emulsions produced by OSA modified starch granules from quinoa can be used in practical applications for the development of highly stable formulations when prolonged storage is required. As the shear stress w, samples. In this study, oil-in-water Pickering emulsions were prepared using Fe3 O4 @cellulose nanocrystal (MCNC) nanocomposites and the effects of CNC/Fe3 O4 (CNC/MNP) ratios, MCNC particle concentration Cmcnc, oil volume fraction φoil and ionic strength on the colloidal stability were evaluated. Combined Emulsifying Capacity of Polysaccharide Particles of Different Size and Shape. Conclusions: https://doi.org/10.1016/j.foodhyd.2018.01.043, http://dx.doi.org/10.1016/j.ejps.2015.11.017, http://dx.doi.org/doi:10.1016/j.carbpol.2017.04.006, https://www.formulaction.com/en/products-and-technologies/product-range/turbiscan-lab. The modified starch showed high emulsifying capacity and stability of the emulsions, thanks to higher oil affinity in comparison to non-modified starch.1, Due to the presence of surfactants, the topical administration of antibiotics and antifungal medication can cause skin irritation in some patients, as previously mentioned.

Native starch is not naturally hydrophobic, and ther, granules, amylose leakage from granules, loss of molecular and crystalline or, temperatures, long times or high shear stresses finally leads to granule disintegration [4]. particles used to generate Pickering emulsions, are edible, abundant and derived from natural sources. Acid hydrolysis was another method used to obtain smaller particles. The emulsions used in the experiments to s, prepared by combining 2.7 ml of continuous pha, amounts (75 mg - 600 mg) and subsequently expos, The samples were stored in sealed test tubes at 5. measurements and determination of volume fractions. & Murray B.S. Dive into the research topics of 'Pickering emulsions, colloidosomes & micro-encapsulation'.

Starch granules isolated from quinoa have been used as emulsion stabilising particles.

∼130 nm, Fig. http://repository.up.ac.za/dspace/bitstream/handle/2263/49551/Phinney_Solar_2015.pdf?sequence=1&isAllowed=y, Particle-stabilized emulsions, called Pickering emulsions, can be produced by using starch particles. the emulsion phase nearly occu, a tendency to increase with storage time, at least for the first four weeks, due to the matching densities of, the drops and the continuous phase. Pickering Emulsions: Versatility of Colloidal Particles and Recent Applications.

The most important specific characteristics of the solid particles which strongly affect their behavior are the high barrier to particle adsorption, high desorption energy and strong capillary forces between particles trapped in liquid films, which all originate in the relatively large particle size (as compared to the size of surfactant and protein molecules). The size of the modified starch particulates was reduced by freezer-milling before preparing the emulsions via a jet homogenizer. The stabilizing capacity of seven different intact starch granules for making oil-in-water emulsions has been the topic of this screening study. (a) Micrograph of unheated oil drops; (b) Micrograph of and heated (70°C, 1 min) oil drops; as vie, This work has demonstrated the emulsifying capaci, resulting emulsions are stable during storage (at least 8 w, use of starches’ physical-chemical characterist, the barrier properties to enzymatic activity at the oi, rate as a measure of the quality of the physical barrier on the drop surfac. This article is protected by copyright. Although the size of the drops was relatively large, the drops themselves were in many instances extremely stable. 2.
