Fluorometric determination of chemically available lysine: adaptation, validation and application to different milk products.
2004
A spectrophotometric method based on the reaction between available lysine and ortho-phthaldialdehyde (OPA) was adapted and validated for fluorometric determination of the chemically available lysine contents in milk matrices (UHT and conventional in-bottle sterilized cow milk, milk-based infant formulas and infant formula ingredients). The values of the analytical parameters show its usefulness as a routine method (linearity, r = 0.9992; detection limit, 0.0066 mg/mL assay; accuracy, 99-108%; precision, intra-day 2.1-5.9% and inter-day 3.5 10.2%). No statistically significant differences (p < 0.05) were found between the values obtained with the adapted method and those obtained applying t…
Temporal drivers of liking
2013
Abstract Generally liking is measured overall but is likely to vary over the food intake, like sensory perception. Replacing the attributes in Temporal Dominance of Sensations (TDS) by the categories of a usual ordinal liking scale makes it possible to monitor liking changes while eating a product (Sudre et al., 2012). This methodology allows for a better understanding of the influence of temporal dominance of sensations on liking and liking evolution over the time of product intake. Thus, it is possible to associate hedonic temporal data and descriptive temporal data (TDS profiles), which would identify drivers of liking, that is attributes which, when cited as dominant, would lead to a de…
Der Einfluss aliment�rer Acidosen und Alkalosen auf die Wachstumsgeschwindigkeit und die Eiweissausnutzung der Ratte
1958
Die Erzeugung einer alimentaren Acidose mit 200 mAq NH4Cl/kg Futter bei wachsenden Ratten fuhrt bei Mannchen und Weibchen zu einer schlechteren Protein-Efficiency, aber nur bei den Mannchen zu einer geringeren Wachstumsgeschwindigkeit. Eine mit NaHCO3 in analoger Weise induzierte alimentare Alkalose hat weder bei den Mannchen noch bei den Weibchen einen sicheren Einflus auf die Protein-Efficiency und auf die Wachstumsgeschwindigkeit.
Über nichtenzymatische Bräunungsreaktionen und ihre physiologischen Folgen. II. Mitteilung. Methoden zur Erfassung von Veränderungen
1956
Es wurde uber die Anwendung verschiedener Methoden berichtet, die geeignet sind, bestimmte, durch-die nichtenzymatische Braunungsreaktion hervorgerufene Veranderungen an einzelnen Aminosauren und am Eiweis zu erfassen.
Die Bedeutung der Topinambur für die Ernährung des Menschen
1950
Das Topinambur als Gemuse in kleinen Mengen verzehrt werden kann, ist bekannt. Auch bei grosen Mengen von Topinambur, anstelle von Kartoffeln gegeben, ist die Ausnutzung im allgemeinen gut. Vereinzelt kann jedoch auch schlechte Ausnutzung beobachtet werden. Die Allgemeinerscheinungen, die nach dem Genus groser Mengen Topinambur beobachtet werden, lassen zunachst einen Genus von Topinambur in grosen Mengen nicht empfehlenswert erscheinen. Es soll versucht werden zu klaren, welche Bestandteile der Topinambur fur die mangelhafte Vertraglichkeit verantwortlich sind und ob durch geeignete Vorbehandlung eine Verbesserung zu erzielen ist, die auch den Genus von grosen Mengen zulast, ohne zu irgend…
What Is the Color of Milk and Dairy Products and How Is It Measured?
2020
Exactly six-hundred (600) scientific articles that report milk and milk products’ color results in scientific journals in the last couple of decades were reviewed. Thereof, the greatest part of the articles derived from Europe (36.3%) and Asia (29.5%). The greatest share of researchers used Minolta colorimeters (58.8%), while 26.3% of them used Hunter devices. Most reports were on cheese (31.0%) followed by fermented products (21.2%). Moreover, the highest number of papers reported color data of milk and milk products made from cow’s milk (44.81%). As expected, goat’s cheese was the brightest (L* = 87.1), while cow’s cheese was the yellowest (b* = 17.4). Most importantly, it appeared that c…
Deficiency of Vitamin C in Dairy Products and Supplementation in Milk by Adding the Bioactive Natural Products
2011
Since milk constitutes an important item in the human diet and since the importance of an adequate amount of vitamin C in the diet is becoming more fully appreciated, it appeared to us that any investigation that might yield further information as to how milks containing greater quantities of this dietary essential might be produced would be worth while. Sea buckthorn is a natural multi-vitamins and a major source of vitamin C, fruits containing vitamin C at a rate of two times more than rosehips and ten times more than citrus (200-1500 mg). Strengthening with Vitamin C will be considering of content of vitamin C in milk samples taken per season (winter, spring, summer, autumn). This contri…
Milk and Dairy Products Intake Is Related to Cognitive Impairment at Baseline in Predimed Plus Trial
2021
Scope: To examine the association between milk and dairy products intake and the prevalence of cognitive decline among Spanish individuals at high cardiovascular risk. Methods and results: Cross-sectional analyses are performed on baseline data from 6744 adults (aged 55-75 years old). Intake of milk and dairy products is estimated using a food frequency questionnaire grouped into quartiles. The risk of developing cognitive impairment is based on the Mini-Mental State Examination (MMSE). A higher prevalence of cognitive decline was found in subjects who consumed more grams. Patients with worse MMSE score (10-24) consumed a mean of 395.14 ± 12.21 g, while patients with better MMSE score (27-3…

Effects of a phytosterol-enriched dairy product on lipids, sterols and 8-isoprostane in hypercholesterolemic patients: a multicenter Italian study.
2009
Abstract Background and aims Plant sterols, added to several food sources, lower serum cholesterol concentrations. Plant sterol-induced cholesterol lowering is paralleled by a mild decrease in plasma levels of the antioxidant β-carotene, the amount of this decrease being considered clinically non-significant. Whether the effect on lipid profile of daily consumption of plant sterol-enriched low-fat fermented milk (FM) is paralleled by a concomitant variation in a reliable marker of the oxidative burden like plasma isoprostane levels is unresolved. Methods and results The effect of plant sterol consumption on plasma lipid and isoprostane levels of hypercholesterolemic patients was evaluated i…
