Triacylglyceride, antioxidant and antimicrobial features of virgin camellia ole...
Feás, Xesús; Estevinho, Leticia M.; Salinero, Carmen; Vela, Pilar; Sainz, Maria J.; Vázquez-Tato, Maria Pilar; Seijas, JulioVirgin oils obtained from seeds of Camellia oleifera (CO), Camellia reticulata (CR) and Camellia sasanqua (CS) were studied for their triacylglyceride composition, antioxidant and antimicrobial activities. Levels of fatty acids determined by 1H-nuclear magnetic resonance analysis were similar to those reported for olive oils (82.30%–84.47%; 5.69%–7.78%; 0.26%–0.41% and 8.04%–11.2%, for oleic, linoleic, linoleni...
Organic bee pollen: botanical origin, nutritional value, bioactive compounds, a...
Feás, Xesús; Vázquez-Tato, Maria Pilar; Estevinho, Leticia M.; Seijas, Julio; Iglesias, AntonioOrganic bee pollen (BP, n = 22) harvested from the Douro International Natural Park (DINP, Portugal) was studied. Nine botanical families were found in the mixture of the samples. The water activity and pH ranged 0.21–0.37 and 4.3–5.2, respectively. The BP analyses averaged 67.7% carbohydrates, 21.8% crude protein, 5.2% crude fat and 2.9% ash. The energy ranged from 396.4 to 411.1 kcal/100 g. The principal fatt...
Physicochemical and pollen analysis of Local honeys from the Lima Valley (Portu...
Estevinho, Leticia M.; Feás, Xesús; Seijas, Julio; Vázquez-Tato, Maria PilarAn evaluation was done on the physicochemical quality of nineteen (n=19) Apis mellifera honeys produced in the Lima Valley, Portugal. The rural landscape of the Lima Valley is valuable in social, environmental and economic terms and its conservation and preservation are essential. The evaluated physicochemical characteristics were: moisture, ash, electrical conductivity, pH, hydroxymethylfurfural (HMF), free ac...
Evaluation of the effect of hidrogen peroxide (H2O2) in the antimicrobial activ...
Feás, Xesús; Seijas, Julio; Vázquez-Tato, Maria Pilar; Dias, Teresa; Estevinho, Leticia M.Bee hive products such as honey, propolis and royal jelly have been extensively used in the past. Their use in Medicine dates back at least 4000 years, to Ancient Egypt where it was used for the treatment of wounds among other conditions. With the discovery of modern antibiotics in the early 20th century, the use of many effective products of traditional medicine was discontinued. Although modern antibiotics us...
