“…The gradual increase of anthocyanin extractability in the media milled red rice could be attributed to the complete breakdown of the material matrix, which enhanced the efficiency during solvent extraction. The enhanced extraction of the bioactive compounds after the media-milling process has also been reported in another study . Previous studies have proved that the prominent anthocyanins in colored rice are cyanidin-3-glucoside and peonidin-3-glucoside.…”

“…Since the original red rice is a mixture of starch, protein, and dietary fiber, it is highly possible that media-milling can be effective in producing nano/submicrometer particles from other resources containing either one or more components. And some studies have already confirmed the production of nano/submicrometer particles from soy bean, yam, and Ganoderma tsugae. ,, …”

Nano/submicrometer red rice particles were obtained through processing a type of red rice using media-milling. The diameters of red rice were gradually reduced as processing time increased. After 4 h of processing, the particle size of milled red rice was reduced to around 692 nm. Microscopic observation and SEM analysis confirmed the presence of nano/submicrometer particles. The phytochemical contents of milled red rice were analyzed. The total anthocyanin content of red rice increased after milling process. Its phenolic and flavonoid contents were slightly decreased after the milling process. All milled red rice exhibited good ferric reducing antioxidant property (FRAP) and DPPH (2, 2-diphenyl-1-picrylhydrazyl) radical scavenging activity. The emulsifying ability of milled red rice particles with different milling time was characterized. Milled red rice starch particles with a concentration of 0.8–3.5% were able to form stable Pickering emulsions, and milled red rice particles retarded the oil oxidation process when being used as Pickering emulsions stabilizers. This pioneer study directly modifies whole grain materials to submicrometer particles that can form stable food grade Pickering emulsions with intrinsic antioxidant properties.

“…As a phytochemical is known to present anti-inflammatory action and also in the control of dyslipidemias (RAJU; MEHTA, 2009). It has antioxidant properties and stimulates the production of collagen (RAJU; MEHTA, 2009;CHIANG et al, 2012), which are increasingly important in the pharmaceutical and cosmetic industries.…”

Nanotechnology is an interdisciplinary scientific field where it is possible to manipulate, alter and develop new materials at the nanoscale, changing their properties. In the pharmaceutical and cosmetic areas there is the production of nanocarriers for pharmaceuticals, which can protect, encapsulate and release pharmacologically active compounds. In our study we chose the nanoemulsion as carrier, since it is widely used as a vehicle for drugs, by the cosmetic and pharmaceutical industry. The drug used was Diosgenin, a steroidal sapogenin, found in roots of the wild yam (Dioscorea villosa). Diosgenin has a structure similar to progesterone and estradiol and is used as a chemical precursor in the industrial preparation of oral contraceptive pills and steroid hormones. The use of nanoemulsified diosgenin topically can bring a great number of benefits to the skin, considering its antioxidant properties and stimulating the production of collagen, thus being able to be incorporated into cosmetic anti-aging formulations. Thus, nanoemulsions can be a vehicle for diosgenin, encapsulating them, protecting them from possible degradation of the active substance and providing better permeation on the skin. The general objective was to produce and evaluate diosgenin containing nanoemulsions, aiming at the choice of a stable formulation. Nanoemulsions at concentrations 1mg.mL -1 , 3 mg.mL -1 and 5 mg.mL -1 were produced using the high energy emulsification method. All formulations were submitted to different forms of storage. The characterization of the formulations allowed to evaluate the formulations of diosgenin nanoemulsions in concentrations 1 mg.mL -1 , 3 mg.mL -1 and 5 mg.mL -1 . The best condition for storing 1mg.mL -1 nanoemulsions without losing their physical-chemical characteristics during the 90-day period was under refrigeration. With this, there is a guarantee of the quality and stability of the diosgenin nanoemulsion, compatibility for topical use and the possibility of reaching the deeper layers of the skin, enhancing the effects of diosgenin. It was also possible to co-validate an analytical method by spectrophotometry in the visible region to identify diosgenin in nanoemulsions, ensuring the presence of the active substance in the nanoemulsion.
