"Pour moi, le goût du soja n'est pas une barrière à la consommation. Et pour vous ?" : Effet de la culture sur les croyances, attitudes et préférence…

2010

Understanding consumers' beliefs, attitudes and sensory preference is the key to a successful development and introduction of a new food. This thesis carried out a series of cross-cultural studies, France vs. Vietnam, on consumers' representation of soy foods and on sensory perception and preference of soy yogurts, a soy derived product recently developed for French market which does not exist on the Vietnamese market. Despite a favourable image of soy in terms of nutrition and health benefices, French participants reported that the barrier to its consumption was the taste of soy. This finding was confirmed by a consumer test in which French participants gave very low hedonic evaluations to…

Melatonin activates the peroxidase-oxidase reaction and promotes oscillations.

2001

We have studied the peroxidase-oxidase reaction with NADH and O2 as substrates and melatonin as a cofactor in a semibatch reactor. We show for the first time that melatonin is an activator of the reaction catalyzed by enzymes from both plant and animal sources. Furthermore, melatonin promotes oscillatory dynamics in the pH range from 5 to 6. The frequency of the oscillations depends on the pH such that an increase in pH was accompanied by a decrease in frequency. Conversely, an increase in the flow rate of NADH or an increase in the average concentration of NADH resulted in an increase in oscillation frequency. Complex dynamics were not observed with melatonin as a cofactor. These results a…

Ode laica per Chibok e Leah

2019

The volume contains two short poems by Nigerian Nobel Laureate Wole Soyinka ("No, He Said!", dedicated to Nelson Mandela, from the Author's 1988 classic collection "Mandela's Earth and Other Poems", and the recent "Mandela Comes to Leah", written purposely for this volume), along with the most recent long poem in five parts "A Humanist Ode to Chibok, Leah", published in English for the first time in 2019. The poem, and indeed the entire volume, denounces all forms of fundamentalism and fanaticism as opposed to secular humanism. Soyinka pays tribute to the girls abducted in Chibok and 15 year-old Leah Sharibu, one of the 108 girls abducted from Dapchi in 2018, comparing her firm refusal to r…

Fatty Acid Transporter CD36 Mediates Hypothalamic Effect of Fatty Acids on Food Intake in Rats

2013

Subject Areas: carotid arteries; emulsions; fatty acids; gene expression; heparin; hypothalamus; neurons; oxidation.; International audience; Variations in plasma fatty acid (FA) concentrations are detected by FA sensing neurons in specific brain areas such as the hypothalamus. These neurons play a physiological role in the control of food intake and the regulation of hepatic glucose production. Le Foll et al. previously showed in vitro that at least 50% of the FA sensing in ventromedial hypothalamic (VMH) neurons is attributable to the interaction of long chain FA with FA translocase/CD36 (CD36). The present work assessed whether in vivo effects of hypothalamic FA sensing might be partly m…

Identification of volatile synomones, induced by Nezara viridula feeding and oviposition on bean spp., that attract the egg parasitoid Trissolcus bas…

2004

Bean plants ( Vicia faba L. and Phaseolus vulgaris L.) damaged by feeding activity of Nezara viridula (L.) ( Heteroptera: Pentatomidae), and onto which an egg mass had been laid, produced volatiles that attracted the egg parasitoid Trissolcus basalis (Wollaston) (Hymenoptera: Scelionidae). Extracts of volatiles of broad bean and French bean plants induced by adults of N. viridula as a result of their feeding activity, oviposition activity, and feeding and oviposition activity combined were analyzed by gas chromatography-mass spectrometry (GC-MS), and tested in Y-tube olfactometer bioassays as attractants for T. basalis females. In extracts from undamaged leguminous plants, green-leaf volati…

Simultaneous analysis of lysine, Nɛ-carboxymethyllysine and lysinoalanine from proteins

2007

Protein quality was assayed by simultaneous measurement of lysine (Lys), carboxymethyllysine (CML) and lysinoalanine (LAL). GC-FID analysis of N-tert-butyl dimethylsilyl (tBDMSi) derivatives of these amino acids was undertaken. tBDMSi derivates were separated on a CP-SIL 5CB commercially fused silica capillary column (25 m × 0.25 mm i.d., 0.25 μm film thickness) employing a thermal gradient programmed from 200 to 300 °C. The identity of tBDMSi derivatives of Lys, CML and LAL was established by GC–MS while FID detection was employed for quantification. Analytical parameters such as linearity (lysine 350–4200 μM, LAL 3–81 μM, CML 16–172 μM), precision (1–13% variation coefficients), accuracy …

Effect of modified starch or maltodextrin incorporation on the barrier and mechanical properties, moisture sensitivity and appearance of soy protein …

2012

Abstract This work aimed to study the effect of starch (acetylated di-starch phosphate and starch acetate) and maltodextrin (DE 10.2 and DE 15.6) on the properties of soy protein isolate (SPI) films. Films were cast from heated (70 °C for 20 min) alkaline (pH 10) aqueous solutions of soy protein isolate (8%) containing glycerol (50% of SPI) as a plasticizer and starch or maltodextrin (20% of SPI). For all types of films, water vapor sorption kinetics during 24 h at 25 °C and 75% relative humidity (RH), diffusion coefficient of water vapor, water vapor permeability at 25 °C for two relative humidity differentials (40–75 and 40–100%), tensile strength and elongation at break, color and micros…

Determination of lecithin and soybean oil in dietary supplements using partial least squares-Fourier transform infrared spectroscopy.

2008

Lecithin and soybean oil in dietary supplements were determined by Fourier transform infrared spectrometry transmission measurements in dichloromethane in combination with a partial least squares (PLS) regression. Two different PLS models were developed, using 16 synthetic mixtures of analytes in dichloromethane, making measurements in the spectral range from 931.8 to 1252.3 cm(-1) for lecithin and from 911.4 to 1246.9 cm(-1) and 1695.3 to 1774.5 cm(-1) for soybean oil. Seven products from the Spanish market with lecithin concentrations between 21.1% and 99.1% and soybean oil concentrations between 0% and 37.2% were analyzed by the proposed method and the data was compared to a chromatograp…
