“…The activity of storage rots in the St. Thomas 2001 samples resulted in substantial increases in glucose and fructose with the increase in fructose being greater. These responses are similar to those reported by Jaggard et al (1997), Martin et al (2001a), andMumford andWyse (1976).…”

. 2007. Characterizing sugarbeet varieties for postharvest storage losses is complicated by environmental effects and genotype × × environment interactions. Can. J. Plant Sci. 87: 121-127. Each year millions of tons of sugarbeet (Beta vulgaris L.) roots are stored in large exposed piles prior to processing. During postharvest storage, respiration and invert sugar formation consume sucrose and even a small reduction in these losses would have substantial economic impact. This study investigated the relative importance of hybrid, environment, and hybrid × environment interactions and examined their implications in characterizing hybrids for sucrose loss during storage or developing hybrids with improved storage properties. Glucose, fructose, and extractable sucrose concentrations and respiration rate were measured 30 and 120 d after harvest (DAH) on five hybrids produced in six environments. Environment effects were significant on both dates for all traits except fructose 30 DAH. Significant hybrid × environment interactions were observed for respiration rate 30 and 120 DAH, for extractable sucrose 120 DAH, and for glucose concentration 30 DAH. The only trait with a significant hybrid main effect was extractable sucrose 30 DAH. For the 90 d between measurements, extractable sucrose losses for individual hybrid-environment combinations ranged from 1 to 63% of the sucrose available 30 DAH. It appeared that large environmental impacts and hybrid × environment interactions, compared to the relatively small hybrid influences, would complicate selecting parental lines with all or most of the storage traits desired. Furthermore, a comprehensive evaluation of commercial hybrids or breeding lines for storage traits would require considerable resources. Efforts to understand the impact of production practices and growing season environment on storage properties would probably be more productive than attempting to produce commercial hybrids with improved storage characteristics.

“…Maximum raffinose content (0.58%) was noticed in period 8 and minimum value 0.36% in period 5 with an average of 0.45%. These results are in agreement with those confirmed by some authors Martin et al (2001), who reported that during storage, raffinose concentrations change with the magnitude and direction of change dependent on storage conditions. Such finding agreement with the results reported by Abdel-Rahman (2007) and Darrin et al (2008), where raffinose was found to impact negatively the sugar beet processing by decreasing extractable sucrose yield and altering sucrose crystal morphology which reduces filtration rates and slows processing.…”

The present study highlights on the effect of over nitrogen content on beet sugar quality, sugar content, alkalinity, impurity value, raffinose formation, chemical impurities especially (Na) ions and the loss of sugar in molasses. The results showed that nitrogen content must be done in the way that causes a high productivity of roots with a high content of sucrose and pureness percentages with low levels of vegetarian growth levels. Also, the acceptable values of α-amino N, K and Na in roots for processing must be about 150, 140 and 700 -1000 mg 100g -1 sugar, respectively. One of the greatest effects is the increment the loss of sugars to molasses rate as a result of the increment of sucrose solubility hence decrement in crystallization. Therefore, this study recommends not to overuse nitrogen fertilization because the increase of the nitrogen inside the roots inhibits the processes of crystallization process hence, decreasing the quality of sugar extraction process.

Long-term storage of sugar beet is an option to extend the processing campaign of the sugar factories in Europe. In the present study, changes in the processing quality of sugar beet were quantified during 110 days of storage at 7 and 20°C. During storage, the concentration of sucrose decreased whereas K, Na, amino N, betaine, invert sugar and raffinose accumulated in the beets, i.e. quality was impaired markedly. At 7°C, the changes in sucrose concentration were relatively small but the formation of invert sugar and raffinose caused considerable losses in beet quality. Thus, long-term storage at low temperature is appropriate to prolong the campaign but processing costs will increase. Quality assessment with two formulae showed that measurements of K, Na and amino N are insufficient to evaluate stored sugar beets for recoverable sugar. Due to its increase in storage, the concentration of invert sugar should also be taken into account.
