Defoliation produced by abiotic factors and the subsequent re-growth can reduce sugar beet (Beta vulgaris L.) sucrose content and final sugar yield. Field experiments were conducted during 2003 and 2004 growing seasons in the farm of Hellenic Sugar Industry SA, Larissa factory, central Greece. Three sugar beet cultivars (Rival, Europa and Corsica) were ordinary irrigated till the beginning of J...

Experiments were conducted in which d-mannose was supplied to mature Beta vulgaris L. (sugar beet) leaves, via the transpiration stream, to perturb photosynthetic carbon allocation by sequestering cytosolic Pi. Biochemical and enzymic analyses conducted on this tissue indicated that mannose 6-P was present, that it was only slowly metabolized, and that after a 24-hour pretreatment sugar metabol...

Palatinose (isomaltulose), a slowly digested disaccharide, is used as a non-cariogenic sugar and as a sucrose substitute in several foods. Because of its ability to lower postprandial glycemia, palatinose may be beneficial as a treatment for impaired glucose metabolism. Glucagon-like peptide-1 (GLP-1) improves glycemia via enhancing pancreatic beta-cell functions. The secretion of GLP-1 is stim...

BACKGROUND Consumption of high-sugar foods stimulates insulin production, which has been associated with endometrial cancer. Although a relationship between sucrose, high-sugar food consumption, and endometrial cancer risk is biologically plausible, this hypothesis has previously been explored in very few studies. METHODS We used data from the Swedish Mammography Cohort, including 61,226 wome...

Sucrose-metabolizing enzymes in plant leaves have hitherto been investigated mainly in temperate plants, and rarely conducted in tandem with gene expression and sugar analysis. Here, we investigated the sugar content, gene expression, and the activity of sucrose-metabolizing enzymes in the leaves of Hevea brasiliensis, a tropical tree widely cultivated for natural rubber. Sucrose, fructose and ...

Carbohydrate sources such as plant exudates, nectar and honeydew represent the main source of energy for many ant species and contribute towards maintaining their mutualistic relationships with plants or aphid colonies. Here we characterise the sensitivity, feeding response curve and food intake efficiency of the aphid tending ant, Lasius niger for major sugars found in nectar, honeydew and ins...

In this research, 5 different pomegranate jams were produced with the addition of anthocyanin-based extract obtained from black mulberry and rose hips by classical ultrasonic extraction methods without extracts (control). The are stored at room temperature (20±2 ℃) for 60 days, ensuring that storage is 0., 20., 40. 60. color, total dry matter, water soluble pH, titration acidity, reduced sugar,...

Sucrose (alpha-D-glucopyranosyl-(1-->2)-beta-D-fructofuranoside) is an inexpensive chemical produced by sugar cane and sugar beet cultivation. Chemical and/or biochemical transformations convert it into highly valuable synthetic intermediates such as 5-hydroxymethylfurfural (HMF), bioethylene, 1,2-propylene glycol and levulinic acid. Sucrose can also be converted into biodegradable polymers suc...

AN ACCU-CHEK PERFORMA DIABETIC biosensor was examined for use as a quantification method for glucose and sucrose within a sugarcane juice medium. The motivation for this study was the need for a fast, inexpensive and reliable primary method for sucrose determination. This proof of concept study obtained promising results, encouraging further development of this project. Calibration curves were ...
