Background and objectives: Stevia rebaudiana Bertoni is a herbaceous and a small shrub of the Compositae family. It is native to certain regions of South America. Since 1970s, Stevia extracts have been extensively used in many countries as a sugar substitute. Stevia is cultivated in many countries: Paraguay, USA, Mexico, Central America, Japan, China,...

in order to evaluate salinity tolerance in 20 sugar bee genotypes, an experiment was conducted in two fields with salinity (ec= 12 ds/m, ph= 7.6) and non-salinity stress, in the form of rcbd at miandoab agricultural research station. different morphological and physiological traits such as root yield, sugar percentage, white sugar percentage, molasses, n, na, k, syrup purity and green cover per...

The study of colour and colour precursors in cane sugar has been an important research area at Sugar Processing Research Institute for many years. Previous studies on isolating colourant precursors have relied on various liquid-liquid extraction procedures, time consuming methods requiring large amounts of sample and solvent. Four methods were examined for the identification of raw sugar colour...

in order to study the possibility of control of heterodera schachtii  in sugarbeet fields through integration of rotation with non- host crops and resistant catch crops and their effects on quantitative and qualitative traits of sugarbeet, this study was started from 2002 for three years in esfahan province. the experiments were carried out in a randomized complete block design with eight treat...

for considering and evaluating the economic impacts of sugar beet research on the shift of sugar supply, we need to estimate the parameter of supply shift. having developed an appropriate methodology and using the results of breeding research collected from the main stations of sugar beet research acrossiranfor the period of 1982-2003, the supply shift parameter for sugar was estimated.  this p...

We studied the global (i.e. overall) structure of microwave-assisted alkaline soluble polysaccharides (ASP) isolated from fresh sugar beet pulp. The objective was to minimize the disassembly and possibly the degradation of these polysaccharides during extraction. Prior to ASP microwave-assisted extraction (MAE), pectin was removed and isolated by MAE. Two sub fractions, ASP I and ASP II were is...

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...

Fermentative bioethanol production from pyrolytic sugars was improved via aromatics removal by liquid-liquid extraction. As solvents, the ionic liquid (IL) trihexyltetradecylphosphonium dicyanamide (P666,14[N(CN)2]) and ethyl acetate (EA) were compared. Two pyrolytic sugar solutions were created from acid-leached and untreated pinewood, with levoglucosan contents (most abundant sugar) of 29.0% ...
