In an environmental background characterized by climate change, the seasonal trend increasingly affects qualitative and quantitative expression of vineyards. The sugar concentration, titratable acidity, ratio sugar/acids yield were related with heat accumulation (growing degree days accumulation), calculated in different period grapevine cycle. 21.5 °Babo threshold has been reached Montepulcian...

The effect of crystal size on VHP sugar colour was evaluated on a factory scale over the 1988/89 season at Sezela. Generally, smaller crystals produced lower sugar colour but the difference wasnot significant (at the 5% level) in the size range tested. Smallercrystals producedloweraffinated sugarcolourand the difference was significant at the 5% level. The mass of sugar in a full rail truck was...

Meat is a rich source of different volatile compounds. The final flavor meat products depends on the raw material and processing parameters. Changes that occur in include pyrolysis peptides amino acids, degradation sugar ribonucleotides, Maillard’s Strecker’s reactions, lipid oxidation, thiamine fats, as well microbial metabolism. A review compounds’ formation was carried out divided into non-t...

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...

Steamconditioning (desuperheating) is an essential and critical part of sugar production, particularly with reference to the processing of expressed juice where criticalsteamtemperatures are most necessary to ensurefinal quality. Desuperheating is a simpleprocess that is not widely understood in principle and is much abusedin its practical application and operation. The purposeof this paper is ...

Thermoplastic properties of extruded sugar beet pulp (SBP) are closely linked to water–polymer relationships. DSC analyses of water evaporation, water fusion and biopolymer relaxation according to SBP moisture content gave a more accurate estimation of SBP hydration steps than classical water adsorption isotherm. Three moisture contents (8%, 26%, 41% db) were then defined as limits of the diffe...

Currently, corn is used to produce more than 85% of the world's high fructose syrup (HFS). There is a search for alternative HFS substrates because of increased food demand and shrinking economies, especially in the developing world. The sweet potato is a feasible, alternative raw material. This study isomerized a high glucose sweet potato starch syrup (SPSS) and determined its sugar profile, m...

the study was carried out in the fields of department of agriculture, university of lorestan, iran(lat. 32°18´ n., long. 45°22´ e.). according to the data gathered in the nearest synoptic meteorological station, the studied region is classified under semi-arid climates. mean maximum and minimum daily temperatures have been recorded in july and january as 29.5 and 5.5°c, respectively. mean annua...

This personal account summarizes our recent developments in gold-catalyzed direct substitutions on propargylic (allylic, benzylic) alcohols, with various nucleophiles (and bi-nucleophiles) based on the σ- and/or π-acidity of gold(III) complexes. Synthetic developments are also briefly described.
