The effect of onion juice on the whitening fresh-cut carrots during storage was explored to optimize processing technology carrots. Using fresh carrot and as raw materials whiteness value reference index, process parameters were optimized by response surface methodology (RSM) based single factor experiment, physiological biochemical indexes determined. Results showed that conditions follows: co...

This study focuses on the analysis of polysaccharide residues from the cell walls of fruits and vegetables: tomato, potato, pumpkin, carrot and celery root. An alcohol-insoluble residue was prepared from plant material by extraction using the hot ethyl alcohol method and then cell wall fractions soluble in trans-1,2-diaminocyclohexane-N,N,N',N'-tetraacetate, sodium carbonate and alkaline soluti...

The minimal requirements to support protein import into mitochondria were investigated in the context of the phenomenon of ongoing gene transfer from the mitochondrion to the nucleus in plants. Ribosomal protein 10 of the small subunit is encoded in the mitochondrion in soybean and many other angiosperms, whereas in several other species it is nuclear encoded and thus must be imported into the ...

The removal of chlorpyrifos pesticide residues from vegetables was achieved by using low level of ozonated water (OZW) for 15 60 min as contact times at 25 and 35oC. Recovered amount of chlorpyrifos was extracted using solid phase extraction (SPE) and then analyzed by gas chromatography-mass spectrometry (GC-MS). The initial levels of residual chlorpyrifos varied with the kind of vegetables, wh...

BACKGROUND Flavors from the mother's diet during pregnancy are transmitted to amniotic fluid and swallowed by the fetus. Consequently, the types of food eaten by women during pregnancy and, hence, the flavor principles of their culture may be experienced by the infants before their first exposure to solid foods. Some of these same flavors will later be experienced by infants in breast milk, a l...

the moist sample shrinks during drying and the non-uniformity shrinkage involves stresses in the body. the aim of the present work is simulating deformations and drying-induced stresses of carrot slice during a convective drying. the effect of shrinkage on the heat and mass transfer profiles were considered. non-constant physical and thermal properties were also incorporated in the model and th...

abstract in order to study the effect of using somaclonal variation on production of resistant lines to water deficit conditions on carrot (daucus carota l.), an experiment was carried out in department of biotechnology of all russian research institute of vegetable crops (raas) in 2008-2009. coated seeds of four carrot cultivars which are cultivated in iran including, monarch, nantes improved,...

abstract somatic embryogenesis is a new approach to in vitro plant propagation. this technique is based on stem cell obtain and its differentiation to a complete plant. this is affected by components of media culture. so, the effects of ms, b5 and nl media on carrot petiole somatic embryogenesis investigated via histological experiment. to do this, carrot petioles (with 1 cm dimension) cultured...

The crop Water Footprint (WF) can provide a comprehensive knowledge of the use of water through the demarcation of the amount of the water consumed by different crops. The WF has three components: green (WFg), blue (WFb) and grey (WFgr) water footprints. The WFg refers to the rainwater stored in the root zone soil layer and is mainly utilized for agricultural, horticultural and forestry product...

The influence of copper sulphate on the regeneration of carrot (Daucus carota L.) androgenic embryos and changes in the levels of phenolic substances and polyamines that might be indicative of the response to oxidative stress were investigated. The cultivation on the regeneration medium supplemented with Cu(2+) at the concentrations 1 and 10 microM for 15 weeks resulted in significant dose-depe...
