Abstract Twelve carrot varieties in different colours and sizes were investigated for chemical properties (dry matter, ash, pectins, titratable acidity, pH), contents of vitamin C, sugar, organic acids, mineral (sodium, potassium, calcium, iron, magnesium), anti-oxidant activities (ABTS, FRAP, ORAC). Moreover, total polyphenolics tetraterpenoids colourful presented. According to the study, sucr...

Before the work of Costantino, the erythrocyte was considered to be impermeable to ammo acids (1, 2). Costantino observed, however, a higher level in the red blood cell than in the serum of groups titratable in the presence of formaldehyde (3). He was also able to demonstrate by this method uptake by red cells in vitro of glycine, asparagine, and the mixture of amino acids contained in a casein...

The influence of the geographical location and clone type on contents flavonols organic acids Sauvignon blanc grapes over ripening process was investigated. assay carried out three commercial clones cv. (Clone 242, Clone 107, 1-Davis) grown in two zones (referred to as low high zones) Casablanca Valley, Chile. zone is closer Pacific Ocean (i.e., 20 km away) than (which 37 away). Clear differenc...

Viticulture is impossible without the use of chemical plant protection agents. Their follows to ecological destabilization ampelocenoses and constitutes real danger human health. Last years there a tendency biologize technologies that relevance studies influence biopreparations on quality graps wines. The article presents results fungicide action preparations Biocomposite-correct Biocomposite-p...

Inducible expression systems are widely employed for the titratable control of gene expression, yet molecules inadvertently present in the growth medium or synthesized by the host cells can alter the response profile of some of these systems. Here, we explored the quantitative impact of these residual inducers on the apparent response properties of inducible systems. Using a simple mathematical...

A low pH and a high titratable acidity of juices and cola-based beverages are relevant factors that contribute to dental erosion, but the relative importance of these properties to maintain salivary pH at demineralizing levels for long periods of time after drinking is unknown. In this crossover study conducted in vivo, orange juice, a cola-based soft drink, and a 10% sucrose solution (negative...

A polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) technique followed by sequencing of the 16S rDNA fragments eluted from the bands of interest on denaturing gradient gels was used to monitor changes in the bacterial microflora of two commercial kimchi, salted cabbage, and ingredient mix samples during 30 days of fermentation at 4°C and 10°C. Leuconostoc (Lc.) was th...

Characteristics developed by Cactaceae for adaptation to climates where water is limited include crassulacean acid metabolism (CAM), a thick cuticle, and spines and trichomes that intercept a proportion of solar radiation. A few studies consider morpho-anatomical and physiological characteristics of Cactaceae seedlings, which may help understand their establishment, growth, and eventual reprodu...
