objective: many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. thus agronomic package must be always modified. this sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (beta vulgaris l.) under different biofertilizers and irrigation closed time at dorud region of iran, during 2013. methods: the experimental design...

background and objectives: over the last two decades, a large number of researches have been conducted regarding the importance of nitrogen in sugar beet. this indicate that there were needs to investigate more on nitrogen management to achive higher production and quality because less nitrogen application result in reducing yield and high nitrogen application would increase production costs an...

this study was intended to evaluate the quality of 30 honey samples, in terms of physicochemical properties such as moisture content, electrical conductivity, ash content, reducing sugars and sucrose, free acidity, ph, diastase activity, and hydroxymethylfurfural (hmf) content. moreover, three methods recommended by the international honey commission for the determination of hmf, including 1) h...

PURPOSE This study examined how college students choose beverages and whether behavioral interventions might reduce their heavy consumption of sugar-sweetened beverages. METHODS From April to June 2010, 90 students participated in 12 focus groups at 6 colleges in Massachusetts and Louisiana. The study team undertook a group content analysis of the verbatim focus group transcripts using the im...

Two green kohlrabi cultivars, ‘White Delikates’ and ‘Korist’ F1, were kept in cold storage at a temperature of 2oC and a relative humidity of 95%. Natural mass losses were measured at monthly intervals and dry matter content, soluble sugars, L-ascorbic acid and isothiocyanates were analysed. During five months of storage, very low losses of kohlrabi mass were detected. The decrease in dry matte...

Kim, M.H., Kim, S.M., Kim, C.S., Park, S.J., Lee, C.H. and Rhee, J.Y. 2002. Quality of Korean ginseng dried by a prototype continuous flow dryer using far infrared radiation and hot air. Canadian Biosystems Engineering/Le génie des biosystèmes au Canada 44: 3.473.54. This study was performed to examine the effects of infrared (IR)/hot-air combination drying on some quality attributes of Korean ...

A valid quantitative method for the analysis of chiral monoterpenes in white wine using head-space solid phase micro-extraction-MDGC-MS (HS-SPME-MDGC-MS) with stable isotope dilution analysis was established. Fifteen compounds: (S)-(-)-limonene, (R)-(+)-limonene, (+)-(2R,4S)-cis-rose oxide, (-)-(2S,4R)-cis-rose oxide, (-)-(2R,4R)-trans-rose oxide, (+)-(2S,4S)-cis-rose oxide, furanoid (+)-trans-...

The aim of this study was to evaluate the quality characteristics of seven yacon (Smallanthus sonchifolius Poepp. and Endl.) cultivars (Cajamarca, Cusco, Early White, Late Red, Morado, New Zealand and Quinault) cultivated in the southwest of Germany. The following phyto/chemical traits were investigated in different yacon tuber parts (flesh, peel, and whole tubers): total dry matter, sugar cont...
