Thus, National Cereals Research Institute, Badeggi has been involved in Research and Development (R & D) of sugar cane for the past 3 and 4 decades respectively. During this period, seven indigenously bred varieties have been released for use by the Nigerian sugar industries. The research efforts on sugar have also witnessed the development of 10 tons per day (10tcd) brown sugar processing technology for cottage level sugar production. In striving to achieve these novel technologies, various stakeholders were collaborated with spanning from the Federal Government, Agencies of Governments at the Federal, state and local levels and the universities with little or no input from the Nigerian Sugar Industry. Due to some encountered deficiency in key areas for sugar cane and sugar research and production, the Institute finds imperative to seek worthy collaborators in Egypt's sugar groups in biotechnology and sugar technologies for the development of suitable varieties foe sugar and ethanol production and the time for this synergy is now. This paper highlights what NCRI has been able to archive in the past decades on sugarcanes and sugar research and areas needing urgent collaboration with relevant Egypt technocrat in sugar cane and sugar.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87847537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the activities of enzymes isolated from distillery yeasts before and after activation were 120 and 1100 IU/ml/min. The activity of lyophilized partially purified powder of enzyme isolated from activated distillery yeast was19300 U/g. The Km and Vmax values of the enzyme isolated from activated distillery yeast were 7.56 mg/ml and 294.12 IU/ml/min, respectively. These results were compared to those values of invertase isolated from Egyptian active dry Baker’s yeast and the commercial invertase data sheet with a sample of sweetase 20 p enzyme obtained from Germany stern enzyme company.

G.2003-47 and G.2003- 49 compared with the commercial variety (G.T. 54-9). The results indicated significant differences among tested genotypes in stalk height, cane yield in the plant cane and first ratoon crops, while stalk diameter and sugar yield exhibited significant differences only in the first ratoon. Row spacing had a significant effect on the number of millable cane / m 2 , cane and sugar yields /fed in the plant cane and first ratoon crops, while it had a significant effect on stalk height only in plant cane crop. The row spacing of 120 cm exerted the highest number of millable cane / m 2 , stalk height, and sugar yield in plant cane and first ratoon crops, as well as stalk diameter, cane yield, Brix, richness and reducing sugars in plant cane only. Moreover, the check cultivar recorded the highest mean value of sugar yield in the first ratoon crop, when planted at 120 cm row spacing. On the other hand, the 80 cm inter row-spacing gave the highest mean values of purity and sugar recovery% in both plant cane and first ratoon crops and Brix, sucrose and richness in first ratoon only. The significant linear effects were found for the number of millable cane / m 2 , stalk height, cane yield, sugar yield and reducing sugar with the rate of row spacing.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86518029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Control points (pH, doses, retention time, color, and turbidity) of this process were evaluated compared with the traditional sulfitation process. The results were evaluated using a statistical T-test. The results showed that the most proper pH, doses and retention time are 7.5, 300 ppm, and 1.5 hr, respectively. Since, applying such values led to a significant reduction in turbidity and color of clear juice (55 % and 19 % respectively) compared with the traditional sulfitation and phosphation process. These results mean a predicted soft scale formed in the evaporators, the lower color of produced sugar, higher sugar recovery, removing the cost of sulfur, and minimizing the cost of calcium oxide to half. The results were discussed via the properties of hydroxyapatite and its highest surface area that adsorbs denatured proteins, prevents the formation of melanoidin coloring compounds and promotes clarification efficiency.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76458924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These sediments can't be removed by traditional methods such as crushing or heating, due to the special condition of the pipe inside the clarifier, its narrow diameter and vertical position. Therefore, chemical methods were used to solve this problem. A new technique was used in this process through a mixture of sodium hydroxide and hydrogen peroxide solution. There are many experiments and attempts to find the most suitable way of addition and also the final required concentrations of 1:1 dilution for both solutions and the diluted sodium hydroxide solution (48%) was added firstly and after 24 hours a solution of hydrogen peroxide was added with twice the amount of sodium hydroxide. This work was based on the fact that the decomposition of hydrogen peroxide in the alkaline medium is accompanied by the release of oxygen, the occurrence of effervescence and the rise of impurities up to the surface of the solution in an exothermic reaction. This method which has been succeeded in removing sediments from the pipe of lengths up to 7 meters, can be considered a new addition in the field of chemical removal of sediments.","PeriodicalId":11564,"journal":{"name":"Egyptian Sugar Journal","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87844812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
