Fatty acid composition of the meat from Mos breed and commercial strain capons slaughtered at different ages
(Consejo Superior de Investigaciones Científicas (CSIC), 2012)Se ha estudiado la influencia de la raza [Mos (raza española autóctona), Sasso T-44 y X-44 (estirpes comerciales)] y la edad (5, 6, 7 y 8 meses) de los capones (gallos castrados) en la composición de ácidos grasos de la ... -
A Green Analytical Method Using Ultrasound in Sample Preparation for the Flow Injection Determination of Iron, Manganese, and Zinc in Soluble Solid Samples by Flame Atomic Absorption Spectrometry
(Hindawi, 2012)A simple and rapid analytical method was developed for the determination of iron, manganese, and zinc in soluble solid samples. The method is based on continuous ultrasonic water dissolution of the sample (5–30 mg) at room ... -
Influence of storage conditions on the sensory and physicochemical characteristics of Galician Kennebec potatoes (Solanum tuberosum L.)
(Taylor & Francis, 2012)In this study, we compared conventional storage of Kennebec potatoes in a ventilated room at ambient temperature with storage at controlled temperatures of 10, 7 and (initially) 4°C as regards the evolution of colour, ... -
Changes in bioactive compounds content and antioxidant activity of seaweed after cooking processing
(Taylor & Francis, 2012)Wakame and Kombu seaweed, both fresh and reconstituted for consumption, were analyzed by HPLC for the determination of the content of ascorbic acid, vitamin E, β-carotene, lutein, fucoxanthin, chlorophyll a and pheophytin ... -
Development of a simple method for the quantitative determination of fatty acids in milk with special emphasis on long-chain fatty acids
(Taylor & Francis, 2012)A new and simple method was developed for the extraction and derivatization of fatty acid (FA) in milk. Lipid extraction of milk was carried out in H2SO4/methanol. Methylation was performed for 2 h at 60°C, and FA methyl ... -
