Molecular analysis of the dominant lactic acid bacteria of chickpea liquid starters and doughs and propagation of chickpea sourdoughs with selected W…
2020
Abstract Fermented chickpea liquid is used as a leavening agent in chickpea bread production. In the present study, traditional chickpea liquid starter and dough samples were collected from bakeries in Turkey and microbiologically investigated. Culture-independent analysis for microbiota diversity, performed by MiSeq Illumina, identified Clostridium perfringens as major group in all samples, while Weissella spp. Dominated LAB community. A culture-dependent methodology was applied and 141 isolates were confirmed to be members of the LAB group based on 16s rRNA gene sequence analysis. In particular, 11 different LAB species were identified confirming the high frequency of isolation of weissel…
The spatial distribution of bacteria in Grana-cheese during ripening.
2012
The microbial composition and its spatial distribution of Grana Trentino, a hard Parmesan-like cheese, was determined, from vat milk to cheese. After cutting along the vertical axis of the cheese wheels, three layers were sampled diagonally across the cheese: under the cheese rind, an intermediate section and the cheese core. After two different ripening periods (9 and 18 months), the cheese samples were analysed using traditional culture dependent and culture independent methods. Milk samples were dominated by mesophilic and psychrophilic bacterial counts. Thermophilic bacteria (Lactobacillus helveticus) were found in high amounts in cooked whey and natural whey starter cultures. After 9 m…
Le violazioni degli obblighi alimentari
2011
La concezione istituzionale della famiglia e l’esigenza di garantire la stabilità del vincolo coniugale, a prescindere e, se del caso, contro la volontà dei coniugi, hanno indotto la dottrina e la giurisprudenza a ritenere che la disciplina dettata in tema di responsabilità civile fosse incompatibile con i legami familiari. Ciò ha determinato per lungo tempo un vuoto di tutela in tutte quelle ipotesi di violazione dei doveri solidaristici sussistenti in ambito familiare, doveri strumentali allo sviluppo della persona. La valorizzazione della tutela della “sfera individuale” rispetto a quella della “formazione sociale” (id est famiglia) hanno però determinato una netta inversione di tendenza…
Beer produced via hydrodynamic cavitation retains higher amounts of xanthohumol and other hops prenylflavonoids
2017
Abstract Some of the most valuable bioactive compounds in beer comes from hops polyphenols, mainly flavonoids, some of which are unique to inflorescences of that flowering plant. Although far from pharmacologically relevant concentrations, low doses of xanthohumol and related prenylflavonoids found in beer contribute to the overall antioxidant activity of the product, as well as to significant chemopreventive action about certain diseases, such as cardiovascular, neurodegenerative, and some cancer types. Hence, the efforts to explore both ingredients and brewing methods aimed at enhancing the concentration of such bioactive compounds. In this study, a novel brewing method assisted by hydrod…
A headspace solid-phase microextraction method of use in monitoring hexanal and pentane during storage: Application to liquid infant foods and powder…
2006
The determination of two secondary lipid oxidation compounds (hexanal and pentane) in liquid infant foods using a headspace solid-phase microextraction gas chromatographic (HS-SPME-GC) method has been developed and validated. The HS-SPME analytical conditions (fibre position, equilibration and sampling times) were selected. The analytical parameters of the method (linearity: hexanal from 2.48 to 84.78 ng/g, pentane from 6.21 to 79.55 ng/g; precision: hexanal 2.87%, pentane 2.343.46%; recovery: hexanal 106.60%, pentane 95.39%; detection limit: hexanal 3.63 ng and pentane 4.2 ng) demonstrate the usefulness of the method. Once optimized, the method was applied to liquid infant foods based on m…
Preconceptional nutrition and pregnancy outcomes: review and Dietitian-Nutritionist intervention proposal
2016
El estado nutricional de la madre antes y durante el embarazo se constata en los últimos años como uno de los factores ambientales más influyentes en el desarrollo fetal. Este estudio se centra en las primeras fases del proceso de gestación o periodo periconcepcional: preconcepción, concepción, implantación, placentación y embriogénesis; puesto que representan un paso crítico en los resultados del embarazo. Tras una revisión bibliográfica exhaustiva de 66 investigaciones publicadas entre los años 1990 y 2015, fueron el zinc, el hierro, el yodo, los ácidos grasos omega-3, el ácido fólico y otras vitaminas del grupo B, los minerales y micronutrientes para los que se han encontrado mayor evide…
Effect of Supplementation with Wheat Bran Aqueous Extracts Obtained by Ultrasound-Assisted Technologies on the Sensory Properties and the Antioxidant…
2015
Phenolic compounds have antioxidant properties and activate endogenous detoxification defense systems able to scavenge the reactive species of oxygen. The external layers of wheat caryopsis, largely constituting by-products of the milling industry such as bran and various middlings, contain relevant amounts of phenolic compounds. The aim of the research has been to evaluate the effect of supplementation with wheat bran aqueous extracts, obtained by ultrasound-assisted technologies, on the sensory properties and antioxidant activity of dry pasta. The HPLC-DAD characterization of the extract evidenced the presence of ferulic and p-coumaric acids. The supplemented pasta showed significantly h…

HPLC profile and evolution during storage of triglycerides and diglycerides in virgin olive oils
2008
High-performance liquid chromatography has been used for determining the triglyceridice and diglyceridice composition of olive oils from main, minor and neglected Sicilians cultivars. The HPLC analysis has allowed the identification and the quantification of 16 triglycerides. Among these, OOO, POO+SOL, OOL and POL, have shown a content higher than 84% of the total area of peaks in the chromatographic profile. Dioleine (OO) and oleopalmitine (OP) resulted the most representative diglycerides. Analyses have been made in January 2007 and repeated after six months, submitting samples to a simulation of shelf life, to verify as the storage conditions may influence the hydrolitic processes of tri…
