Feasibility study on the use of infrared spectroscopy for the direct authentication of Iberian pig fattening diet

A dual-emission fluorescence-enhanced probe for imaging copper(ii) ions in lysosomes

“…5 Therefore, it is interesting to study the relationship between copper levels in cells especially in lysosomes and neurological symptoms of disorders of copper metabolism. Several analytical techniques including atomic absorption spectrometry, 6 inductively coupled plasma atomic emission spectrometry, 7 voltammetry, 8 electrochemical method 9 have been devoted in detection of Cu 2+ . Although these methods are sensitive toward Cu 2+ , they are usually complex and time-consuming and/or need special equipment.…”

Consumption of Acorns by Finishing Iberian Pigs and Their Function in the Conservation of the Dehesa Agroecosystem

“…The establishment of more stringent standards, the requirement for more accurate controls to avoid frauds (for example: infrared spectroscopy; Arce et al, 2009) and a greater consumer information are keys to protect the traditional Iberian pig farms; because to maintain the montanera finishing system it is essential to conserve the dehesa agroecosystem and its profitability. In this sense, it has been proposed to establish stocking rates on the base of adult oaks density (a mean of 46 trees/pig), very easily calculated with the use of geographic information system (GIS) (Rodríguez-Estévez et al, 2010c).…”

“…Consequently, there is a new market for fresh meat from intensive farming imitating the acorn diet fatty acid profile, exploiting the image of traditional products and consumers lack of information and trying to avoid official control based on the fatty acid profile (López-Vidal et al, 2008;Arce et al, 2009). …”

Application of artificial neural networks to determine the authentication of fattening diets of Iberian pigs according to their triacylglycerol profiles

“…The profiles of fatty acids (Cava et al, 1997, Flores et al, 1988, Ruiz et al, 1998, triacylglycerols (Díaz et al, 1996, NarváezRivas et al, 2009, VieraAlcaide et al, 2007, hydrocarbons (VieraAlcaide et al, 2009;Gamero Pasadas et al, 2006;NarvaézRivas et al, 2008) and volatile compounds (NarvaézRivas et al, 2010(NarvaézRivas et al, , 2011 have been related with the fattening diets of Iberian pigs and can be used as chemical descriptors to differentiate among the different feeding backgrounds of the animals. Nearinfrared spectrometry (NIR) is another method that has been used for the authentication of this animal fattening diet (Arce et al, 2009;Hervás et al, 1994;Zamora Rojas et al, 2011. This is a very simple, fast, cheap and nondestructive technique, but it does not differentiate perfectly among the different fattening systems and does not give information about the sample chemical composition.…”
