Quality control of fruit juices by using organic acids determined by capillary zone electrophoresis with poly(vinyl alcohol)-coated bubble cell capil…
2015
An enhanced method for the determination of organic acids in several fruit juices by capillary zone electrophoresis (CZE) with direct UV-Vis detection has been developed in this work. First, a study with simulated real juice samples was done to find the best separation conditions. Next, several commercial fruit juices were analyzed, and the organic acid contents were quantified in less than 12 min using a poly(vinyl alcohol)-coated fused-silica 'bubble cell' capillary. The present method is reliable, fast and provides detection limits comprised between 0.1 and 2.5 μg mL(-1). Moreover, different chemometric techniques, based on CZE data, were examined. Linear discriminant analysis allowed th…
The Lasting Influences of Early Food-Related Variety Experience: A Longitudinal Study of Vegetable Acceptance from 5 Months to 6 Years in Two Populat…
2016
International audience; Children's vegetable consumption falls below current recommendations, highlighting the need to identify strategies that can successfully promote better acceptance of vegetables. Recently, experimental studies have reported promising interventions that increase acceptance of vegetables. The first, offering infants a high variety of vegetables at weaning, increased acceptance of new foods, including vegetables. The second, offering an initially disliked vegetable at 8 subsequent meals markedly increased acceptance for that vegetable. So far, these effects have been shown to persist for at least several weeks. We now present follow-up data at 15 months, 3 and 6 years ob…
Analisi della produzione e del mercato dei prodotti di IV gamma in Italia
2007
Il volume si articola in due parti: la prima approfondisce l’analisi della produzione e del mercato in Europa, con particolari specificazioni e approfondimenti sulla situazione produttiva e organizzativa esistente in Francia: Paese, come sopra specificato, dove nacque e dov’è più diffuso il comparto della produzione e della commercializzazione dei prodotti di IV gamma; la seconda si diffonde sull’analisi della produzione e del mercato in Italia, con particolare attenzione alla situazione siciliana.
Ensenyant Horta, aprenent paisatge. Anàlisi dels discursos educatius sobre el paisatge de l'Horta i propostes de millora
2017
Al País Valencià existeixen espais agraris periurbans que conformen paisatges d'especial singularitat com ara l'Horta de València, que malgrat la seua importància està travessada per múltiples problemàtiques. Als centres d'educació secundària la majoria dels discursos sobre espai agrari que es transmeten des dels manuals escolars i el professorat s'hi apropen de manera taxonòmica, pobre i simplificadora, així com des d'un punt de vista únicament productivista, obviant tota la resta de dimensions des de les quals es pot analitzar un paisatge. Un ensenyament més convenient sobre els espais agraris a la comarca de l'Horta hauria d'estar íntimament lligat al medi local, així com contemplar tote…
Use of triacylglycerol profiles established by high performance liquid chromatography with ultraviolet–visible detection to predict the botanical ori…
2011
A method for the determination of triacylglycerols (TAGs) in vegetable oils from different botanical origins by HPLC with UV–vis detection has been developed. Using a core-shell particle packed column (C18, 2.6 micron), TAG separation was optimized in terms of mobile phase composition and column temperature. Using isocratic elution with acetonitrile/n-pentanol at 10 °C, excellent efficiency with good resolution between most of the TAG peak pairs, within a total analysis time of 15 min, was achieved. Using mass spectrometry detection, a total of 15 peaks, which were common to oils of six different botanical origins (corn, extra virgin olive, grapeseed, hazelnut, peanut and soybean) were iden…
trans -Lycopene from tomato juice attenuates inflammatory biomarkers in human plasma samples: An intervention trial
2017
cope : To evaluate the effects of carotenoids from tomato juice (TJ) on inflammatory biomarkers, by performing a 4-week dose-response nutritional trial in a population at high cardiovascular risk. Methods and results : An open, prospective, randomized, cross-over, and controlledclinical trial was carried out with 28 volunteers (mean age 69.7 ± 3.1 years; mean BMI 31.5 ± 3.6 kg/m2) at high cardiovascular risk, which were assigned to consume daily for 4 weeks in random order: 200 mL (LD) or 400 mL (HD) of TJ, or water as a control (C), with a 21-day wash-out period between each intervention. Blood samples were collected at baseline (B) and after each intervention. Endpoints included significa…
The role of information and communication technologies and logistics organization in the economic performance of Sicilian fruit and vegetable enterpr…
2013
Through a direct survey conducted on a sample of firms operating in the Sicilian fruit and vegetable sector, the present study provides an empirical evidence on the degree of diffusion of ICTs as well as on relationships with the regional distribution system. To pursue this goal, a multiple regression analysis model was implemented to identify which factors affect more the economic results of fruit and vegetable enterprises. The main results of the analysis indicate that firms using specific software for accounting, warehousing, payment and sales orders and contracts, are more likely to obtain higher economic performances under the “coeteris paribus” condition, as well as firms which are eq…
Inhibition of the mutagenicity of 2-nitrofluorene, 3-nitrofluoranthene and 1-nitropyrene by vitamins, porphyrins and related compounds, and vegetable…
1997
When 21 vitamins including related compounds haemin, chlorophyllin, chlorophyll, biliverdin and bilirubin, as well as juices from five fruits and 25 vegetables and solvent extracts from the residues of fruits and vegetables were tested for their antimutagenic potencies with respect to mutagenicity induced by 2-nitrofluorene (2-NF), 3-nitrofluoranthene (3-NFA) and 1-nitropyrene(1-NP) in Salmonella typhimurium TA98 the following results were obtained. The tetracyclic nitroarenes 3-NFA and 1-NP were in general more effectively antagonized by potent antimutagenic compounds than the tricyclic 2-NF. beta-Carotene, retinol, retinal, retinoic acid, retinol palmitate, riboflavin 5'-phosphate, alpha-…
Survey of microbial quality of plant-based foods served in restaurants
2013
This study was carried out to evaluate the microbiological quality of plant-based foods obtained from foodservice establishments. The samples included cereals, legumes, fruits and vegetables. According to the European Commission Regulation (No. 2073/2005 and No. 1441/2007) and Spanish microbiological criteria (No. 3484/2000), vegetables were the plant-based dishes where more samples exceed the adopted limits of mesophilic aerobic counts and Enterobacteriaceae. Furthermore, Staphylococcus aureus and Escherichia coli were also found in several vegetable dishes. E. coli and Salmonella spp. were detected in 6.6% and 0.7% of lettuce samples, respectively. However, all the samples were negative f…
Evaluation of silver-infused polylactide films for inactivation of Salmonella and feline calicivirus in vitro and on fresh-cut vegetables
2012
There is a growing trend to develop packaging materials with an active role in guarantying that the quality and safety characteristics of packaged products will remain or improve from preparation throughout shelf-life. In the present study, 0.001-1.0 wt.% silver ions were satisfactorily incorporated into polylactide (PLA) films by a solvent casting technique. Silver migration from the films was measured by voltamperometry and then correlated with its antimicrobial efficacy against Salmonella enterica and feline calicivirus (FCV), a human norovirus surrogate, by using the Japanese industrial standard (JIS Z 2801). The PLA-silver films showed strong antibacterial and antiviral activity in vit…
