role of vitamins in bee nutrition is very important especially in case of supplemental feeding with sugar and pollen substitutes. in this experiment effects of different levels of vitamin c on the rate of queen lying and workers body protein were studied. experimental colonies had the same age queens and the same population (5 frames). this study was held at april and july 2011 in three levels ...

Sugar syrup and molasses from beet processing containing 620 and 570 mg/mL sucrose, respectively, were assayed as low-cost and available substrates for the enzymatic synthesis of fructo-oligosaccharides (FOSs). A commercial pectinase (Pectinex Ultra SP-L, from Aspergillus aculeatus) characterized by the presence of a transfructosylating activity was used as a biocatalyst. The FOS production inc...

In the food industry, syrups containing a high concentration of sugar used for fruit preservation is abundantly discharged as a food processing waste and disposed by incineration, resulting in the rise of the manufacturing cost and environmental pollution. This study demonstrates how waste syrup can be utilized as carbon source for production of docosahexaenoic acid (DHA) and astaxanthin by the...

Mangroves are ecosystems in coastal areas that economically have excellent benefits derived from wood, seeds, and fruit. The most frequently used mangrove fruit as a food source is Sonneratia alba fruit, can be to produce syrup. This study aimed determine the effect of sugar on organoleptic properties Mangrove syrup test method hedonic (preference test) using rating scale 1 (dislike very much),...

yog-ice cream (frozen yogurt), is a kind of frozen dessert which has similar features to ice cream in physical and appearance characteristics. recently, there has been a growing interest in using frozen yogurt due to existence of lactic acid bacteria & fermentation processing. besides, yog-ice cream contains lower levels of sugar, fat & emulsifiers than ice cream. this research was conducted to...

M.F. MORSELLI and M.L. WHALEN Maple Research Laboratory Botany Department College of Agriculture and Life Sciences University of Vermont October 1987 FINAL REPORT We had two objectives in the study of sugar maples which showed signs of decline and stress on a roadside where deicing salt was used in the winter. One goal was to determine If tree stress is related to the levels offsodium and chlor...

abstract in this study the possibility of utilizing date syrup as a sugar replacer in soft ice-cream was investigated. for this purpose control sample was formulated based on iranian ice- cream standard. data syrup which produced from third grade kabkab dates, replaced sucrose in four levels (25, 50, 75 and 100%). physical properties including overrun, viscosity and freezing point (drawing temp...

As a result of deterioration in the colour and polarisation of the VHP sugar caused by abnormal cane quality during October of the 1983/84 crushing season, it was decided to test a modified boiling system at Illovo as proposed by van Hengel at the SASTA Congress of 1983. The results achieved for the period before, during and after the trial are presented and compared. It was found that the qual...

Elucidating the mechanisms by which honey bees process pollen vs. protein supplements are important in the generation of artificial diets needed to sustain managed honeybees. We measured the effects of diet on protein concentration, hypopharyngeal gland development and virus titers in worker honey bees fed either pollen, a protein supplement (MegaBee), or a protein-free diet of sugar syrup. Wor...
