Quantifying Nectar Secretion Capacity of Dombeya torrida (J. F. Gmel.) for Honey Production

The honey production potential of a honey plant is assessed based on the total floral nectar secretion capacity of the plant foraged by honeybees within a specific location. This study aimed to assess the honey production potential of Dombeya torrida plants by examining their nectar secretion dynamics. A group of flowers was enclosed with mesh bags a day before collecting nectar to measure the accumulated volume. Nectar volume, concentration, and ambient temperature were measured at hourly intervals. The data collected were analyzed using statistical methods including one-way ANOVA and linear regression. The average sugar content per flower per season was found to be 14.3 mg, with a range from 2.3 to 47 mg. Based on this, each D. torrida tree was estimated to secrete an average of 0.94 kg of sugar, with a range from 0.15 to 3.1 kg. Nectar volume and concentration varied throughout the day, with temperature significantly influencing nectar concentration. The study estimated that a single D. torrida tree could yield around 1.2 kg of honey per flowering season, with a range from 0.18 to 3.78 kg. Additionally, on a larger scale, D. torrida plants were projected to produce an average of 300 kilograms of honey per hectare, ranging from 45 kg to 945 kg. These findings suggest that D. torrida has considerable potential for honey production. Consequently, planting and conservation of this plant for sustainable honey production practices is recommended.

Using electrodialysis to increase the efficiency of sugar enterprises

The paper shows the efficiency of electromembrane treatment of semi-products of sugar production in order to increase the yield of sugar by reducing its losses in molasses. Based on the analysis of changes in the studied parameters of semi­products of sugar production during the electrodialysis process, scientific data were obtained on the effect of electromembrane treatment on the chemical composition and technological quality of purified semi­products of sugar production, as well as on decrease in calcium salts content in them. The purpose of the research is to create a highly efficient method for production of white sugar, allowing to increase the yield of sugar from raw materials and reduce the amount of excipients by means of electrodialysis with its subsequent practical implementation at industry enterprises. Under production conditions, it was found that electromembrane treatment of one batch (7 t) of purified juice allows to additionally obtain up to 35 kg of sugar, a batch of syrup – up to 130 kg, and soft sugar effluent of II crystallization – up to 255 kg. Electromembrane treatment of molasses makes it possible to: reduce the mass fraction of calcium salts to dry matters by 39 % of their initial content; increase molasses purity by 8.5 %; reduce the molasses-forming coefficient by 21 % by reducing the content of potassium and sodium. In this case, the estimated amount of additional sugar obtained from it will make 5.1 % by weight or 392.7 kg of sugar from one batch of processed molasses. The research will allow to develop scientific and technological aspects of purification of semi-products of sugar production using electromembrane treatment.

A Novel Approach to Minimize Energy Requirements and Maximize Biomass Utilization of the Sugarcane Harvesting System in Sri Lanka

Sugarcane harvesting requires a significant amount of energy and time to manage dry leaves after the harvesting process. Therefore, the objective of this study was to minimize the energy requirement to process the cane and dry leaves’ harvesting (CDLH) for sugarcane while, at the same time, maximizing sugar production from cane and energy from dry leaves in Sri Lanka. The CDLH was conceptualized using a novel approach to optimize sugarcane harvesting to maximize biomass supply for energy production while reducing supply chain sugar-loss. The CDLH was investigated for manual harvesting capacity, energy consumption, sugar loss, and biomass energy potential. It was observed that CDLH consumed higher energy compared to the present practices of harvesting. However, the energy used for fieldwork was reduced because of the shifting of cane chopping and cleaning from the field to the factory. Low bulk density of the harvested cane of the CDLH system had a higher energy requirement in transportation. Comparatively, CDLH showed higher biomass energy potential and less sugar loss. High energy potential increases the energy potential to consumption ratio compared to the existing method. Therefore, the theoretical evaluation showed that the CDLH system can produce more than 20 kg of sugar and 879 MJ of electricity when processing 1 t of sugarcane.

Excellent environmental performance of beet sugar production in the Netherlands

To get more insight in the environmental performance of the Suiker Unie beet sugar, Blonk Consultants performed a comparative Life Cycle Assessment (LCA) study on beet sugar, cane sugar and glucose syrup. The system boundaries of the sugar life cycle are set from cradle to regional storage at the Dutch market. For this study 8 different scenarios were evaluated. The first scenario is the actual sugar production at Suiker Unie. Scenario 2 until 7 are different cane sugar scenarios (different countries of origin, surplus electricity production and pre-harvest burning of leaves are considered). Scenario 8 concerns the glucose syrup scenario. An important factor in the environmental impact of 1kg of sugar is the sugar yield per ha. Total sugar yield per ha differs from 9t/ha sugar for sugarcane to 15t/ha sugar for sugar beet (in 2017). Main conclusion is that the production of beet sugar at Suiker Unie has in general a lower impact on climate change, fine particulate matter, land use and water consumption, compared to cane sugar production (in Brazil and India) and glucose syrup. The impact of cane sugar production on climate change and water consumption is highly dependent on the country of origin, especially when land use change is taken into account. The environmental impact of sugar production is highly dependent on the co-production of bioenergy, both for beet and cane sugar.

Determination of sources of sulfur dioxide in confectionery

Sulfur dioxide is used to ensure the safety of fruit raw materials and semi-finished products used for the production of confectionery. This preservative has allergenic properties. In accordance with the Technical Regulations of the Customs Union TR CU 022/2011 "Food products in terms of their labeling" the content of sulfur dioxide must be specified when labeling confectionery products, if its content exceeds 10 mg per kg. The definition of this preservative in raw materials, semi-finished products and confectionery in accordance with the current GOST 26811 “Confectionery. The iodometric method for determining the mass fraction of total sulfuric acid is often difficult because of the complexity of confectionery products, the formation of intensive staining of the solutions under study and the ability of sulfur dioxide to react with other components of the objects under study. Therefore, the task of developing methods with the optimization of the sample preparation stage of the samples under study, which allow one to fully determine sulfur dioxide in confectionery products, semi-finished products and raw materials, is relevant. The purpose of this work was to develop methods for determining sulfur dioxide in raw materials, semi-finished products and various names of confectionery products, as well as assessing the impact of these types of raw materials and semi-finished products on the content of sulfur dioxide in confectionery products. The results showed that sulfur dioxide is present in many raw materials. In mg per 1 kg of sugar in white sand from 1 to 9, molasses from 25 to 52, wheat flour from 9 to 15, starch from 3 to 17. In fruit raw materials from 5 to 545 mg per kg. In confectionery: marshmallow and marshmallow from 8 to 29, gingerbread from 6 to 25, biscuits from 0 to 16, chocolate from 8 to 13. Based on the data obtained, it can be concluded that the content of sulfur dioxide in raw materials and semi-finished confectionery products is a very wide range, which makes it necessary to control the quality of all raw materials entering the production. Sulfur dioxide, used as a preservative for fruit raw materials, can significantly increase the content of this allergen in confectionery made using such raw materials. Ensuring the level of sulfur dioxide less than 10 mg / kg is achieved using raw materials with low content of sulfur dioxide and technological methods.

Perfection of the Technology for Production of Canned Apple Compotes Using Secondary Resources and Intensive Sterilization Regimes

This paper presents the results of research on improving the technology for production of canned apple compotes using secondary products after cutting and cleaning fruit for syrup boiling and intensive heat sterilization based on the use of new techniques—preliminary heating of fruit in cans in the ultrahigh frequency electromagnetic field with sterilization under intensive regimes with the use of high-temperature heat carriers and rotation of the cans during sterilization. It is established that the use of the resulting infusion of secondary products for syrup boiling provides saving of more than 8 kg of sugar per tube of product. In this case, the content of vitamin C in the finished product is more than two times higher than in the case of using the traditional method of blanching in hot water. Studies on the heating and actual lethality of microorganisms have shown that the developed mode provides the industrial sterility of canned food, saves heat energy, and shortens the duration of the heat sterilization mode by 20 min.

Techno-Economic Analysis of Forest Residue Conversion to Sugar Using Three-Stage Milling as Pretreatment

This study quantifies the cost of cellulosic sugar production using a fully-mechanical pretreatment process and fuel pellets as a co-product. The pretreatment reduces softwood forest harvest residuals to micron-sized amorphous particles. Energy consumption is minimized using a three-stage milling process. A techno-economic analysis was completed for a milling facility with saccharification and wood pellet manufacture. For the base case, concentrated sugar syrup can be produced for $0.496/kg of sugar. Sensitivity analyses were used to determine cost controlling variable, optimize the sugar cost and found that siting for this technology needs to strongly consider electricity cost and to a lesser extent local feedstock availability. If the sugar produced in this process is used to generate biofuel and is qualified for RIN credits through a life-cycle analysis, the effective cost could be reduced by $0.04-$0.06/kg of sugar. An additional $0.067/kg savings is possible if the biofuel facility is located adjacent or on-site; the finished sugar syrup would not have to be concentrated for transportation. An optimized scenario, including the RIN credit, dilute sugar syrup, and favorable energy costs and consumption, could reduce the cost to $0.34/kg sugar compared to $0.496/kg for the base case.

Investigation of enzyme formulation on pretreated switchgrass

This work studied the benefits of adding different enzyme cocktails (cellulase, xylanase, β-glucosidase) to pretreated switchgrass. Pretreatment methods included ammonia fiber expansion (AFEX), dilute-acid (DA), liquid hot water (LHW), lime, lime + ball-milling, soaking in aqueous ammonia (SAA), and sulfur dioxide (SO 2). The compositions of the pretreated materials were analyzed and showed a strong correlation between initial xylan composition and the benefits of xylanase addition. Adding xylanase dramatically improved xylan yields for SAA (+8.4%) and AFEX (+6.3%), and showed negligible improvement (0–2%) for the pretreatments with low xylan content (dilute-acid, SO 2). Xylanase addition also improved overall yields with lime + ball-milling and SO 2 achieving the highest overall yields from pretreated biomass (98.3% and 93.2%, respectively). Lime + ball-milling obtained an enzymatic yield of 92.3 kg of sugar digested/kg of protein loaded.
