Consumer understanding of nutrition and health claims is a key aspect of current regulations in the European Union (EU). In view of this, qualitative and quantitative research techniques were used to investigate consumer awareness and understanding of product claims in the UK, focusing particularly on nutrition claims relating to sugars. Both research methods identified a good awareness of product claims. No added sugars claims were generally preferred to reduced sugars claims, and there was a general assumption that sweeteners and other ingredients would be added in place of sugars. However, there was little awareness of the level of sugar reduction and the associated calorie reduction in products when reduced sugars claims were made on pack. In focus groups, participants felt deceived if sugar reduction claims were being made without a significant reduction in calories. This was reinforced in the quantitative research which showed that respondents expected a similar and meaningful level of calorie reduction to the level of sugar reduction. The research also identified consumer confusion around the calorie content of different nutrients, including over-estimation of the calorie content of sugars. This is crucial to consumers' expectations as they clearly link sugar to calories and therefore expect a reduction in sugar content to deliver a reduction in calorie content. © 2012 The Authors.

Sugar manufacture has changed a lot in the UK since the first factory opened 99 years ago in Cantley, Norfolk. Increasing the number of sugar products available to both bulk and retail customers remains an obvious choice for an expanding sugar business, but although sugar is at the core of its operations, British Sugar is now operating outside the box. Harvesting its process streams to diversify into new markets, and produce a range of sustainable co-products from Topsoil to tomatoes to bioethanol, British Sugar's highly integrated approach to manufacturing allows the company to efficiently transform its raw materials into sustainable products.

Relatively cheap, poor quality, unprepared biomass materials can be difficult to burn efficiently on a large commercial scale because of their variable composition, relatively low calorific values and high moisture contents. Consequently it is often necessary to co-fire these materials with a hydrocarbon support fuel to ensure stable and efficient combustion. Fluidised bed combustion (FBC) is a promising method for burning mixtures of fuels with widely differing individual characteristics although there is a need for further information on the "optimum" conditions for efficient operation as well as on the proportions of support fuel which should be used in particular applications. This paper is therefore concerned with co-firing of coal with pressed sugar beet pulp, (a solid biomass with an average moisture content of 71%), in a lab scale (<25. kW net thermal input) fluidised bed combustor. The project was undertaken in collaboration with British Sugar plc. who operate a large coal-fired fluidised bed, with a nominal thermal rating of 40. MW, to generate hot combustion gases for use in subsequent drying applications. The combustion characteristics of different coal and pressed pulp mixtures were investigated over a wide range of operating conditions. For stable combustion the maximum proportion of pulp by mass in the blended fuel was limited to 50%. However under these co-firing conditions a fixed bed temperature can be achieved with 20% lower fluidising air (when compared with coal alone) since evaporation of the moisture in the pressed pulp provides additional cooling of the bed. This reduction in excess air will be beneficial for the output of the full scale plant at British Sugar since at present the flow rate of the fluidising air and hence the amount of coal which can be burnt is limited by high pressure drops in the bed air distributor system. The pressed pulp has relatively low nitrogen levels and hence a further benefit of co-firing is that NO. x emissions are reduced by about 25%.Agglomeration of the bed can be a problem when co-firing biomass because of the formation of "sticky" low melting point alkali metal silicate eutectics which result in subsequent adhesion of the ash and sand particles. Consequently, longer term co-firing tests were undertaken with a 50/50 blended fuel by mass. Problems of bed agglomeration were not observed over the duration of these tests and moreover, scanning electron microscopy (SEM) studies indicated that the levels of alkali metals in the ash were relatively low. © 2014 Elsevier Ltd.

Over the last five years, a number of changes have taken place within the European Sugar Sector mostly driven by the reform of the European Sugar Regime. This Regime had been in place since 1968 and was designed to maintain employment and standards of living for EU growers of beet sugar by making the continent self-sufficient in sugar production. This presentation highlights the changes that have taken place to the Regime and how the Sugar Industry within Europe has altered to meet the new requirements. Sugar Beet Growers and Processors are examining alternative strategies, resulting in new R&D initiatives, to ensure the stability and continuation of the industry in the future. These have included Biofuel production, greater power generation involving CHP plants, alternative fuel sources, product diversification, and refining of imported cane sugar. These initiatives will illustrate what a European sugar producer could be making and using in the near future. Source

A new model is presented that relates the numbers of bolters in sugar-beet crops to an intensity of vernalization calculated as the accumulated number of hours between sowing and the end of June that temperatures were between 0 and 13C, with each temperature within this range differentially weighted for its vernalizing effect. The model allows varieties to be characterized in terms of a threshold number of vernalizing hours needed to induce bolting (the vernalization requirement) and the increase in the proportion of bolted plants with each additional 10 vernalizing hours accumulated above this vernalizing threshold (the bolting sensitivity). When parameterized for variety, the model allows the level of bolting to be predicted for crops sown on specific dates in particular locations. Data from variety-assessment trials done at a wide range of locations throughout the main UK sugar-beet growing areas between 1973 and 2006, and from early sown bolting trials done at a few sites between 2000 and 2008, were used to define specific aspects of the model. These included the range and weightings of vernalizing temperatures, the period during which vernalization occurs, and the temperatures likely to cause plants to become devernalized. The vernalization-intensity bolting model was parameterized and validated using separate subsets of the UK variety-assessment trial data. It was shown to be more discriminating and robust than an existing cool-day model, which relates bolting to the number of days from sowing in which the maximum air temperature was below 12C. Examples are given of the use of the new model to assess the bolting risk associated with early sowing in different regions of the UK, to interpret recent patterns of bolting (especially the large numbers of bolters seen in some commercial crops in 2008), and its potential use as an advisory tool. © 2009 Cambridge University Press.
