Sugar beet quality analysis is an integral part of breeding and sugar beet processing and therefore contributes to the success of the beet sugar industry. This review summarizes the chronological development of important methods used for sugar beet quality analysis, with a special focus on the role that breeding companies, such as KWS, have played in establishing these methods. Finally, new technological advances are highlighted that provide possibilities to automate the analysis of quality parameters of fresh sugar beet outside of the laboratory.

The 19Th Century

Abstract In the second half of the 19th century, sugar beet started its triumphal march through the southern provinces of the Russian Empire, where it soon became a main crop in the process of the modernization of agriculture. The beet-growing agricultural enterprises were considered by the state authorities as prime examples for the use of modern technology, increasing yields and more efficient organization of labour. Entrepreneurs from the sugar beet industry were people of very different social background. Using individual educational and capital resources, they benefitted enormously from the recently discovered sugar-bearing crop. This contribution focuses on the emergence and establishment of the beet sugar industry and the associated emergence of a new agrarian elite. Petrenko outlines the spread of beet sugar production in the Russian Empire, paying particular attention to its south-western region. Focusing on the development of the beet sugar industry, her analysis sheds light on the connections between the onset of modernization and the actions of individual actors. In order to illustrate the new entrepreneurial activity, this contribution outlines the rise and fall of the two rural “beet sugar dynasties” – that of the Yahnenko and the Symyrenko families.

The Impact

In the earlier SugarProTech Facts1, Part 1, it has been explained that, apart from the traditional beet quality criteria (i.e. sugar content, K, Na, N, soil tare), additional quality criteria should be looked upon too, so to reduce their impact on processing. The invert sugar content of sugar beet is one of the most important quality parameters and thanks to recent developments it is now possible to routinely determine the glucose content of sugar beet in the tarehouse from which the total invert sugar content can be calculated. In Part 2 of this beet quality topic it will be demonstrated that incorporating invert sugar in the (Dutch) formula for predicting the sugar loss to molasses – and so the extractability of sugar from beet – has markedly improved the correlation between beet quality analysis and sugar recovery in factory practice. The impact of the invert sugar content in beet on both sugar recovery and the need of alkali addition to process will be quantified, thereby distinguishing different beet qualities.

Series Of Experiments

A study was carried out in six beet sugar factories in France during the 2012/13 sugar campaign. The objective was to assess the optimal dosage of formaldehyde solutions at specific process stages and in different existing factory set-ups in order to obtain the desired effect on microbial populations, without interference with the quality of the products. In addition harmlessness regarding consumer health was to be demonstrated. A series of experiments was conducted resulting in new data allowing refreshment of common knowledge and references existing regarding the use of formaldehyde solutions in the sugar industry. The effectiveness and convenience for controlling microbiological activity in beet sugar manufacture was assessed. Formaldehyde reduces sugar losses and protects in-process products without harming their further use, such as for ethanol production.

Trial Phase

The technological beet quality has been always important for the processors of sugar beet. An investigation into the development of the beet quality in the Netherlands since 1980 has shown that beet quality has improved significantly. Internal quality parameters that are traditionally determined in the beet laboratory, i.e. sugar content, Na, K and -aminoN, all show an improving trend over the years. In the factories, better beet quality has led to lower lime consumption in the juice purification and significantly higher thick juice purity. In 2013, Suiker Unie introduced the serial analysis of the glucose content in beet brei as part of the routine quality assessment of the beet. The invert sugar content is subsequently calculated from glucose content with a new correlation. The background, the trial phase and the first experiences with the glucose analyzer are discussed.

Abstract Background A prospective cohort study was performed to evaluate whether the Optical Quality Analysis System (OQAS) can serve as a valuable additional indicator for appropriate posterior capsulotomy referral. Methods One hundred and five eyes from 96 patients undergoing capsulotomy were divided into precapsulotomy logMAR CDVA ≤0.1 group and logMAR CDVA > 0.1 group. CDVA, and the Visual Function 14 index (VF-14) score were estimated before and 1 month after capsulotomy. The objective scattering index (OSI) value was measured by using the OQAS. Posterior capsule opacification (PCO) severity was assessed with Evaluation of PCO 2000 (EPCO 2000) software. Results In logMAR CDVA > 0.1 group, the correlations of OSI, logMAR CDVA, EPCO score and VF-14 score were very strong preoperatively. In logMAR CDVA ≤0.1 group, preoperatively, OSI was correlated with logMAR CDVA (r = 0.451), EPCO score (r = 0.789), and VF-14 score (r = 0.852). LogMAR CDVA has weak correlation with VF-14 score (r = − 0.384) and EPCO score (r = 0.566). VF-14 score was correlated with EPCO score (r = − 0.669). In the logMAR CDVA ≤0.1 group, there was no significant difference in logMAR CDVA between precapsulotomy and postcapsulotomy (P > 0.05). In the two groups, all the other optical quality parameters were significantly improved after capsulotomy (P < 0.05). In logMAR CDVA > 0.1 group, the area under the curve of the ROC of the OSI was 0.996 (P = 0.000). In logMAR CDVA ≤0.1 group, the area under the curve of the ROC of the OSI was 0.943 (P = 0.000). Conclusions The OSI was useful for evaluating of PCO and prediction of beneficial capsulotomy. Especially for patients with slight PCO and better visual acuity, OSI is more valuable than CDVA and completely objective examination. Trial registration The study protocol was registered at the Chinese Clinical Trial Registry. Register: ChiCTR1800018842 (Registered Date: October 13th, 2018).
