“…For a deep evaluation of antioxidant capacity of Squalene vegetable fractions and their nanostructured formulations, the TEAC decolorization assay based on the radical scavenging capacity of antioxidants against the ABTS •+ has been used. This assay is an excellent tool for the determination of the antioxidant activity of hydrogen-donating antioxidants and of chain-breaking antioxidants (Shao et al, 2014). The efficacy of lipid nanocarriers co-encapsulating various amount of Pm and Hes to scavenge ABTS •+ is shown in Fig.…”

“…It might be that the essential oils have a function of antioxidant in laboratory studies (Suhail et al, 2015;Bi et al, 2016). It is reported that that the active ingredients of essential oils from Anoectochilus roxburghii can eliminate free radicals including 1,1-Diphenyl-2-picrylhydrazyl radical 2,2-Diphenyl-1-(2,4,6-trinitropheny l) hydrazyl (DPPH); 2, 2'-Azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) and the superoxide anion (O2-) (Shao et al, 2014). The THY and ORE groups had more positive results than the CAR group in the prevention of oxidation reactions.…”

A total of eighty 21-day-olds (1.1±0.01kg) ROSS 308 broilers were randomly allocated into 4 groups, with 20 replicates per group and 1 chicken per replicate per cage. Three experimental groups (CAR, THY, ORE group) were given oral administration of 200ìL essential oils (carvacrol, thyme and oregano) at 18:00h every day. The results showed no significant differences on blood metabolites among each group (P>0.05). The villus height of the small intestines in the CAR group increased significantly (P less than 0.05) from 1360.10 to 1552.54ìm as compared to the control group, the goblet cell counts in the THY and ORE groups significantly increased by 20.91% (P less than 0.05) and 31.82% (P less than 0.05), respectively, compared to the control group. The E.coli and Salmonella in ORE group significantly decreased by 11.16% (P less than 0.05) and 9.54% (P less than 0.05), respectively, compared to the control group. The Redness (a*) values of the muscles of the CAR and ORE groups were observed to increase significantly (P less than 0.05) from 3.58 to 7.95 and 6.86, respectively, compared to the control group. In conclusion, oral administration of the essential oils carvacrol, thyme, and oregano promoted intestinal development, improved the intestinal environment and the meat quality of broilers.

“…An alternative method to the conventional techniques is the supercritical extraction, which uses supercritical fluids as solvents (Pereira et al, 2004;Shao et al, 2014;Machado et al, 2013). The extraction with supercritical fluid consists in the transference of mass based on the use of fluids to temperatures and pressure above the critical values.…”

Grapes are placed at a distinct position, both in the economy and at nutritional and phytochemical levels. The number of studies performed aimed at identifying the various bioactive compounds of grapes, how their cellular structures are linked, efficient methods of extraction and its effect on human health are rather relevant. The use of grapes for wine production is a worldwide activity, therefore a great quantity of residues are generated. These, in turn, are commonly used in soil fertilization and animal feed. Research in the food, pharmaceutical, medical and agricultural industries have revealed a great potential of using grape residue to recuperate phenolic compounds, flavonoids and especially the resveratrol. These have been found by these researches to offer benefits associated to its consumption, such as improvements in glucose tolerance in diabetic patients, decrease in the occurrence of cardiovascular diseases, diminishing the symptoms of menopause, protection against osteoporosis, cancer and Alzheimer's disease. The present work aimed at gathering information about the characterization of the phytochemical content of grapes and its residues, as well as gathering data about the extraction process of such compounds and their application in the food industry.
