“…The most abundant FA was linoleic acid (C18:2 n-6, LA; 36.33 g/ 100 g total FA), followed by a-linolenic acid (C18:3 n-3, ALA; 32.59 g/100 g total FA) and oleic acid (C18:1 c9, OA; 23.50 g/100 g total FA). BP consists of skins, pulp residue and seeds, with the latter containing the major content of FA and a notable high proportion of unsaturated FA such as OA (21.8%), LA (35.9%) and ALA (36.1%) (Yang et al 2011). Although studies on the FA composition of bilberries are still scarce, Bunea et al (2012) also showed that OA, LA and ALA are the most abundant FA in some wild and cultivated Romanian blueberries.…”

The aim of the present study was to evaluate the effects of dietary bilberry pomace (BP) on colour, cooking losses, proximate composition and fatty acid (FA) profile of hind leg meat in growing rabbits. One hundred and forty-four Grimaud weaned rabbits (35 days old) were randomly divided into four groups of 36 animals each and fed ad libitum with a basal diet (C diet) tested against three assay diets developed by substituting 50, 100 and 150 g/kg of the C diet with BP (BP5, BP10 and BP15 diets, respectively). At 83 days of age, the rabbits were slaughtered without fasting. Inclusion of BP in the diet did not significantly affect colour, cooking losses, ash and protein contents, but determined a significant increase of ether extract in the muscle. Increasing dietary inclusion of BP also determined a proportional increase of total polyunsaturated fatty acids (PUFA) and total n-3 FA, as well as a proportional decrease of total saturated fatty acids (SFA), total branched chain fatty acids (BCFA) and total monounsaturated fatty acids (MUFA) in the muscle. Dietary BP significantly improved the PUFA/SFA ratio, the R n-6/R n-3 FA ratio and the atherogenicity, thrombogenicity and hypocholesterolemic/hypercholesterolemic FA indexes of rabbit meat but it decreased D5-desaturase plus D6-desaturase index. The obtained results suggest that BP inclusion in growing rabbit diets can improve the fatty acid profile of hind leg meat, with consequent health benefits to consumers. ARTICLE HISTORY

“…Most of them used scCO 2 laboratory-scale extraction installation (up to 2 L extraction vessel) to obtain oils from the most popular fruits, vegetables, or herbs, e.g., grapes, olives, and sunflowers (Yang et al 2011;Rai et al 2016;Aladić et al 2015;Milić et al 2015;Duba and Fiori 2015;Del Valle 2015;Da Porto et al 2012a, b), but only a few of them used supercritical CO 2 industry-scale extraction plant to obtain oils, especially from berry seeds .…”

Fatty Acids Analysis Using Gas Chromatography-Mass Spectrometer Detector (GC/MSD) - Method Validation Based on Berry Seed Extract Samples

2017

Oily seed extracts were used as research samples in Analytical Laboratory of Raw Materials and Plant Products. Supercritical carbon dioxide extraction on an industrial scale was used to prepare extracts from raw plant materials, usually berry seeds: blackcurrant, raspberry, strawberry, and chokeberry. Gas chromatography analysis was performed on Agilent equipment with single quadrupole mass spectrometer detector and split/splitless injector. Fatty acids (FAs) were determined using indirect method, where they were converted to c o r r e s p o n d i n g m e t h y l e s t e r s ( FA M E s ) d u r i n g trimethylsulfonium hydroxide solution reaction. Comparing the mass spectrum and retention time peak, more than 30 compounds in different oily extracts were qualitatively identified. Quantification of individual fatty acids was based on two different methods. Firstly, it was based on the received peak area, and the results were normalized without correction factor. Secondly, the quantification was based on external calibration curve, for 34 identified fatty acids. The method was validated, and the results, e.g., linearity, precision, limit of detection (LOD), and limit of quantification (LOQ), were presented.

“…Similar composición de insaturados fue reportada por Yang, et al (2011) y Micic et al, (2015 con el 91,2% y 93,48% respectivamente, y con alguna variación se observa en los resultados obtenidos por Fazio et al (2013) con un rango de 84-88,6% y Conrado (2008) el 89,85% de insaturados.…”

“…Diversos autores sostienen que, dependiendo de la técnica de extracción, tipo de solvente utilizado y condiciones de operación aplicadas, el rendimiento de aceite proveniente de las semillas de mora, puede oscilar entre 9,2 y 18,3% (Pasquel et al, 2014;García et al, 2003). El producto es rico en ácidos grasos insaturados como saturados (Micic et al, 2015;Cerón, et al, 2012), cuenta con un alto contenido de tocoferoles y esteroles (Van Hoed et al, 2009) y además, posee actividad antioxidante que incrementa su potencial industrial (Yang et al, 2011).…”

*Autor a quien debe ser dirigida la correspondenciaRecibido Abr. 26, 2016; Aceptado Jun. 15, 2016; Versión final Ago. 14, 2016, Publicado Feb. 2017 Resumen En este trabajo se estudió el efecto de los parámetros de extracción del aceite de semillas de mora (Rubus glaucus), utilizando CO2 supercrítico como solvente. Se evaluaron diferentes condiciones de presión y temperatura, que permitieron analizar el rendimiento, la composición y la actividad antioxidante del producto extraído. La identificación de los componentes del aceite se realizó a través de cromatografía de gases y la actividad antioxidante se determinó aplicando el método de ABTS. El rendimiento más alto fue 14.5%, obtenido bajo las mejores condiciones de trabajo: 350 bar de presión y 60°C de temperatura. El aceite proveniente de semillas de R. glaucus se caracteriza por contener un 96% de ácidos grasos insaturados, de los cuales el ácido linoléico es el más abundante (61.6%) y por la presencia de sustancias como β-sitosterol, 24-metil-cicloartanol, α-tocoferol, γ-tocoferol, δ-tocoferol, además de una capacidad antioxidante equivalente al trolox de 604 µmol/100 g aceite.
