Comparisons of 2x, 3x, and 4X sugarbeet (Beta vulgaris L.) lines and hybrids were made to determine the effects of ploidy level on sucrose yield and quality components in equivalent and non-equivalent hybrid populations. The relative order of importance for the components of recoverable sucrose was generally the same for all three ploidy levels, with root weight having the greatest path coeffic...

Freeze-dried systems containing sucrose and organic acids were found to undergo rapid nonenzymatic browning, even at low relative humidities. Addition of protein reduced the rate of browning, especially at low humidities. It was determined that the browning was due to reducing sugars produced by acid-catalyzed hydrolysis of sucrose. This hydrolysis occurred even when water content was well belo...

Introduction Proper nutrition has the task of providing right amount energy and nutrients. A balanced diet should include vegetables fruit at every meal. These products are rich in vitamin C, which is involved many metabolic pathways body. well-balanced will generally provide you with enough ascorbic acid. The content vitamins depends on factors, including place origin product, season, species,...

Through a joint SASEX/CIRAD, project the effect of Eldana saccharina Walker (Lepidoptera: Pyralidae) damage on stalk yield components was studied in fields at the SASEX farms at Gingindlovu and Empangeni. The formal experiment design consisted of randomised plots to compare natural infestation, artificial infestation and chemical treatments. Damaged stalks from infested plots had lower sucrose,...

The Amalgamated Sugar Company has been involved for years in the application of ion exclusion chromatography to the enhanced recovery of sucrose from sugarbeet process streams. Laboratory-scale tests of a simulated moving bed chromatography system for sucrose recovery from sugarbeet molasses were initiated in August 1981 and pilot scale tests were begun shortly thereafter. The technology develo...

The effect of storage on apple juice concentrate was determined by following changes in composition during a period of 111 days at 37°C. Results showed that storage caused an 87% loss in the total free amino acids, which was mostly due to decreases in glutamic acid, asparagine and aspartic acid. The form01 titration method was inadequate for determining the amino compounds involved in Maillard-...

Nineteen strains of Gram-positive cocci isolated from wine and belonging to the genus Leuconostoc were examined and are considered to form a new species which is named Leuconostoc oenos. These strains differ from other leuconostocs because they grow better in a medium containing tomato juice than in yeast glucose citrate broth normally used in this laboratory for the genus. Furthermore, they gr...

Investigations have demonstrated that ratio of sugars to organic acids affects the particular taste of citrus fruit and carotenoids are essential for prevent of the disease.  It seems that some rootstocks enhance the ripening of fruits and stimulatethe biosynthesis of sugars and carotenoids. The aim of this study was to evaluate the effect of rootstocks on sugars, organic acids andcarotenoids o...

1 i The sucrose crystal habit has changed over recent years as a result of a substantial variation in the nature of juice impurities. This has had an impact on the quality of sugar and on the performance of the factory. The aim of the work described here was to find I I out how some oligosaccharides, obtained in different ways, affect the sucrose crystal 4 habit. Several experiments were done t...

It has been postulated that individuals reporting an idiosyncratic symptom response after glutamate ingestion might also experience such symptoms after aspartame ingestion. Such sensitive subjects might have been missed in earlier studies of aspartame. In the present study, six subjects reporting various symptoms after glutamate ingestion, but not after placebo, were administered aspartame (34 ...
