To understand competitiveness, it is imperative to compare total production costs, including both raw material (farm) and processing costs (mill). Therefore, farmlevel production costs from agri benchmark combined with an engineering approach to calculate processing costs were merged to calculate sugar production costs in Germany and Brazil. The necessary data related to investment costs and technical coefficients was obtained in collaboration with BMA. Results show that processing one ton of white sugar (excluding raw material costs) from sugarcane in Brazil is more than USD30/t cheaper than processing sugar beet in Germany. Including raw material costs and the sales of byproducts, white sugar production in Brazil has a total cost advantage of USD112/t over German factories. Key differences in production costs are associated with labor (20%), depreciation (20%) and energy costs (40%). The findings indicate that even with equivalent raw material costs, the lower net processing costs are a major competitive advantage for Brazilian sugar producers. The combination of the typical farm approach and the dynamic engineering model can be applied to other regions, allowing for the estimation of regional production and shifts in global sugar supply.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"62 12","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72367759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the determination of textural properties of sugar beet roots with a texture analyzer a reliable method description is missing. This study aimed to evaluate the impact of washing, soil tare, storage period from washing until measurement, sample distribution and number of roots on puncture and compression measurements. For this purpose, in 2017 comprehensive tests were conducted with sugar beet roots grown in a greenhouse. In a second step these tests were carried out with different Beta varieties from a field trial, and in addition, a flexural test was included. Results show that the storage period after washing and the sample distribution had an influence on the puncture and compression strength. It is suggested to wash the roots by hand before the measurement and to determine the strength no later than 48 h after washing. For reliable and comparable results a radial distribution of measurement points around the widest circumference of the root is recommended for the puncture test. The sample position of the compression test had an influence on the compressive strength and therefore, needs to be clearly defined. For the puncture and the compression test it was possible to achieve stable results with a small sample size, but with increasing heterogeneity of the plant stand a higher number of roots is required. The flexural test showed a high variability and is, therefore, not recommended for the analysis of sugar beet textural properties.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"25 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83310211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Varying contents of T2000 and T40 dextran in sugar solutions corresponding to DS contents of thin juice were investigated. For particle size and shape analysis, static image analysis and laser particle size analysis were used. Both methods, static image analysis and laser diffraction, revealed that the presence of T2000 and T40 dextran leads to a higher amount of large-sized particles at the expense of small-sized particles, indicating pronounced agglomeration. The additional evaluation of shape parameters (circularity, roundness, solidity) obtained from static image analysis indicates that the agglomeration is oriented in the absence and in the presence of lower T40 dextran levels. Besides, non-oriented agglomeration, resulting in more round agglomerates with smoother surfaces, was found for samples loaded with T2000 dextran and high T40 dextran levels. Only the latter samples have shown to negatively affect the filtration performance. Thus, in the presence of T2000 dextran and high T40 dextran levels, the filtration was hampered. This appears to be mainly caused by a tighter packing of more round calcium carbonate agglomerates in the porous structure of the filter cake.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"892 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77025120","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Somaclones of NIA-2010, a high yielding variety with moderate sugar recovery, were developed through callus culture. After initial selection, fifteen somaclones were transplanted in field along with the parent, for two consecutive years. Some of the somaclones illustrated improved quantitative traits viz. height, girth, internodes length, and tillers per plant; whereas, cane quality related characters including CCS, sugar recovery and purity were enhanced in most of the tissue culture derived plants. However, none of the somaclones could surpass the parent in terms of sugar yield per ha. Pearson’s correlation analysis indicated a strong positive correlation of the cane quality related traits among each other. Analysis of genetic parameters depicted considerably greater genotypic variance than the environmental variance, and high heritability for all the characters studied. Two somaclones i.e. 1026-P24 and 1026-P12 showed exceptionally high cane quality traits as compared to other somaclones and the parent. Hence, they can serve as potential candidates for cultivation and adoptability in Pakistan.","PeriodicalId":54362,"journal":{"name":"Sugar Industry-Zuckerindustrie","volume":"55 1","pages":""},"PeriodicalIF":0.4,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81454827","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
