The main idea of the collaborative project “SUSMILK: Re-design of the dairy industry for sustainable milk processing” is to analyze and optimize the whole process chain for milk and milk products with regard to energy and water consumption. The project aims at developing new concepts and technologies for the supply of heat, cold and power and integrating them into the respective process steps. A central part of the project is the integration of innovative and efficient technologies into a green dairy concept that will aim at maximizing water and energy savings. Main objectives include: application of new technologies for heat generation and distribution in dairies; adaption of new chilling technologies; application of membrane filtration techniques for an innovative pre-concentration of milk; development of new concepts for low temperature drying of milk; optimizing/classifying of waste-stream treatments for water savings and/or energy production; testing of all technologies and concepts in pilot applications under real life conditions; LCA of the entire dairy food chain and development of a decision making tool for more competitive and green dairy plants and; energy-based analysis to show the full potential of energy and water savings within the dairy industry. Expected results include: The evaluation of the feasibility, efficiency, and economy of the technology developments to reduce the water and energy demand in the dairy to establish a resource efficient food processing; concepts based on research results to highlight the potential for recycling of energy and mass flows by transforming waste flows into valuable products and; a green dairy simulation tool based on all the data generated within the different pilot and demonstration plants, which will help engineers and the dairy industry to design new and to adapt existing facilities

Title: Integrating new technologies in dairy operations to reduce overall water and energy consumption
Time : 10:25-10:50
Ana Lucia Vásquez-Caicedo obtained MSc in Food Science and Technology from University of Arkansas (USA) and a PhD from University of Hohenheim (Germany). She has experience on product and process development in the fruit and vegetables, bakery, dairy and the beverage sectors. She has joined Fraunhofer IGB in 2009 and leads the group “Aseptic Technologies” focusing on process development for the stabilization of foods and manufacturing of cosmetic ingredients. Her experience includes development of innovative processes and their integration into established manufacturing processes, conducting risk analyses and evaluating the impact of introducing new technologies.
With 13% of the total European Food and Drink industry turnover, the dairy industry is considered one of the most important sub-sectors as well as and one of the highest energy and water consumers, both overall and per unit production: up to 6.47MWh (5.55MWhth and 0.92 MWhel) and an average of 2m3 of water per ton processed milk. The production of milk powder and other dairy powder products in the EU has risen continually in recent years due to increased export demand, thus having a major impact on overall water and energy consumption in EU dairies. Therefore, the whole processing line of these products was analyzed and hot spots identified. Pre-heating of concentrates (45-52% solids) and/or viscous products like yogurt and quark prior spray drying remain one of the major challenges due to the formation of fouling and burn-on, which impacts on product quality and creates costs associated with downtime for cleaning and maintenance. Accordingly, microwave pre-heating technology has been identified as a promising alternative to indirect heating using plate heat-exchangers or tubular heaters. Current experiments with quark, a fresh cheese-like a micro-gel suspension, have shown no fouling formation and homogeneous product quality enabling longer processing times and substantial reduction of cleaning efforts. Additionally, rapid microwave pre-heating to a temperature inlet of 50°C increased spray dryer throughput by 11%. Presently, studies on overall energy consumption with an integrated microwave pre-heating unit are being conducted at an industrial site.

Title: Enthalpy – Reducing energy and water usage in dairy and spray drying due to innovative technologies
Time : 10:50-11:15
Pieter Debrauwer obtained his MSc in Aerospace Engineering at Delft University of Technology and is currently working as Program Manager at TNO in the field of 3D printing. He is involved in R&D projects both in EU as well as in contract research. One of the spin-outs of 3D printing is the use of mono-disperse atomizing for spray drying. He is the Coordinator of the Enthalpy project which brings multiple innovative technologies to the dairy processing, which should lead to a reduction of energy use by 60%.
The Enthalpy project is an European FP-7 project, which overall objective is to significantly reduce energy and water consumption in the European dairy industry, by 63% and 18% respectively. This will lead to increased competitiveness in the dairy sector. To achieve this, innovations are introduced and existing technologies are adapted. These investigated innovations are mono-disperse atomising, radio-frequency heating for the pasteurisation step, membrane distallation in the feed line, membrane contactor on the exhaust of the spray dryer, solar thermal energy for reheating the drying air and enzymatic cleaning of all processing units. Besides introducing these innovative units also a process systems engineering approach is implemented to optimese the processing plant as a whole instead of optimising individual units. These innovations are validated on labscale and will be demonstrated at a pilot plant to show the potential of upscaling these technologies to production units. Next to the sustainability aspects of these developments also the impact on the product quality is investigated, because at a minimum the same product quality needs to be obtained. While the project aims at the dairy industry the technologies have a wider applicability and can result in significant improvements in different sectors.

In this presentation, a methodology for the global process management of the milk and yogurt production processes used as a case study in the European project EnReMilk will be described. At the beginning, three strategies were considered taking into account several aspects of the process management, namely: safety management, production optimization and system optimization. After analyzing the three strategies, the consortium of project agreed to focus on the development of the production optimization. The production optimization problem addresses the optimal batch scheduling of a real power milk/ yoghurt process by means of a constraint programming approach. First, the process and production rules are modeled using a set of constraints. Then, an objective function that includes the process optimization criteria is defined. After the definition of the constraints and objective function, an optimization problem that is formulated and solved using a constraint programming solver, namely the IBM ILOG Optimization Studio. A set of scenarios changing the consume ratio of evaporators, that consider an uninterrupted 15 full days in the underlying powdered milk and yogurt production facilities, are presented to illustrate the validity and performance of the proposed approach.

Thermal pasteurization is the standard stabilization method used in raw milk, however alternative non-thermal methods are demanded not only to protect sensory and nutritional properties, but also for reducing energy and water consumptions. In the present study, the suitability of using the pressure change technology (PCT) which uses inert gases (N2 and Ar) for the treatment of milk was investigated. Performance trials were carried out on a continuous PCT system treating skimmed raw milk with an initial total bacterial plate count (TBPC) of 5.4 log CFU/ml at different operation conditions. TBPC and pH were analyzed before and directly treatment and variations were monitored during six days of cold storage (5-7°C). Results show that TBPC of the skimmed raw milk was reduced by 1.39 log direct after the PCT treatment and maintained during 6 days. The pH was monitored during the 6 days of storage shifting from 6.1 to 5.1. The TBPC in the PCT treated samples changed from 4.08 log (day 1) to 4.20 CFU/ml after 6 days of storage. In both of cases, microbial load remained below the minimum accepted microbial load level (4.47 log CFU/ml) established by the EC standards. It was concluded; that PCT treated skim milk can be stored for few days as an intermediate product in dairy plants or used for the production of cheese or other dairy products. This case study as well demonstrated that using the PCT technology energy and water consumptions can be reduced by up to 50% in comparison with classical pasteurization.

Title: Innovation process configuration in Mozzarella (Pasta filata) and milk powder production aiming at reduced water and energy consumption
Time : 12:20-12:45
Reinhard Kohlus is full time Professor for “food process engineering and powder technology” at the University of Hohenheim in Stuttgart, Germany. His background is process engineering particularly particle technology. His working experiments includes several positions at Unilever B. V., both in research and development, dealing with products like dry soups, seasonings, bouillons and instant-drinks. Particularly research interests include spray drying, agglomeration and coating technologies, behavior of dry food products that mean all low aw products, the generation and optimization of in use properties of these products as well as structure analysis of granulated or otherwise structured powders.
EnReMilk aims at significant water and energy savings in representative dairy case studies, mozzarella and milk powder production, across the supply chain. The dairy industry is an important food industry sector with sales of €124.3 billion and added value of €17.4 billion p.a. It is a high energy and water consumer, both overall and per unit production. 98% of the fresh water used is of drinking water quality with 80% of energy consumed in process heating, pasteurization, sterilization, drying and cleaning operations. The case studies of a novel Mozzarella process and skim milk powder production by spray drying will show approaches and results on technology based water consumption savings and reduced energy requirements respectively. In Mozzarella production, a continuous process has been developed based on understanding of rheological behavior and structuring of cheese curd. The technology will be presented and placed in the broader context of the total production process. Reduction in energy consumption in the spray drying process is tackled especially by super-heated steam drying. This process has proven to allow the reutilization of the latent heat of evaporation. The specific use in spray drying of dairy products has particular aspects due to the heat sensitivity of the product. Energy balance, specific benefits, issues and draw backs will be presented as well as reference results from alternative pilot plant spray drying approaches and placed in the context of production results.
- Special Session on "The Importance of Minerals from Bottled Waters
Ingegerd Rosborg has completed her PhD from Lund University and performed additional studies and projects at both Lund University, Sweden, and KTH, Royal Institute of Technology, Stockholm, Sweden. She has been working as a Nutrient Therapist, Drinking Water Analyst and Health Evaluator at her company Miljö Näringsbalans Vatten (Environment Nutrient Balance Water) since 2000. She has published more than 25 papers in reputed journals and in COST Action 637, “Metals and related substances in drinking water”. She is an IWA specialist group Swedish representative.
The study from 2002 presents the concentrations of about 50 metals and ions in 33 different brands of bottled waters on the Swedish market. Ten of the brands showed calcium (Ca) concentrations <10 mg L/1 and magnesium (Mg) levels <3 mg L/1; origin primary rock bedrock. Three of these had low concentrations of sodium (<7 mg L/1), potassium (<3 mg L/1) and bicarbonate (<31 mg L/1). Contrary, water with high concentrations can substantially contribute to the daily intake of elements. Nine of the brands were collected from limestone regions. They showed Ca-levels >50 mg L/1, maximum of 289 mg L/1. Mg-levels were >90 mg L/1 in two brands. Two waters were supplemented with Na2CO3 and NaCl, resulting in elevated Na (644 and 648 mg L/1) and chloride (204 and 219 mg L/1). Such water types may make a substantial contribution to the daily intake of NaCl in high water consumers. The storage of carbonated drinking water in aluminum (Al) cans increased the Al-concentration to about 70 lg L/1. The levels of Fe (iron) and Mn (manganese) and potentially toxic metals were generally low. Nowadays bottled waters are more and more RO (Reverse Osmosis) treated, causing completely de-mineralized waters, comparable to distilled or rain water. Acute symptoms from drinking many liters of RO water are decreased electrolyte levels causing tiredness, weakness, headache, trembling, coma, and brain edema. In the long run; acidosis, with increased risk for cardiovascular diseases, osteoporosis and diabetes etc., is a great risk.

Test sale through online grocery stores opens up for better consumer insights. A European FP7 SME research project named “Increased utilization and consumption of barley for better health” with the acronym BARLEYboost, tested new fiber enriched barleybread in order to develop a new cost efficient method for real-life testing of minimum viable food products (mvp’s). The experiment was conducted through the online grocery store www.kolonial.no in 2015. Free samples were handed out to known costumers with and without approved health claims, printed on the products. The health claim “Maintenance of normal blood cholesterol concentrations” due to its high on fiber from beta-glucan content, referred to at least 1g/meal as a necessary daily dose of 3g/day. The experiment indicated that health claims printed on the product had no significant effect on increased sales of barleybread. Mapping consumer behavior using big data technics at online stores, opens up for a new way of rapid prototyping with validated learning for the food industry. By studying behavior of barleybread consumers vs. average costumers, at the online grocery store, using social network analyzing methods, we find new patterns of consumers enabling us to group consumers in new segments. This will help us in more efficient mvp experiments for maximum learning, during new product development, in a new cost-efficient experimental design.

Brazil has considerable territorial peculiarities and plant species diversities, sometimes from the same botanical family. The fruits can exhibit significant differences in properties of the oils extracted. As example can be cited Brazil Nut (Bertholletia excelsa), Sapucaia nuts (Lecythis pisonis camb.), Amazonas tucumã (Astrocaryum aculeatum Meyer), Pará tucumã (Astrocaryum vulgare Mart.), Chicha (Sterculia striata), Peanut (Arachis hypogaea L.) among other. The raw materials of great relevance, as oils from seed and pulp, have been widely investigated due to its lipid content and potential application, fatty acid profile, and bioactive compounds. The extration process can interfere in some properties of the obtained oils, as quantity and quality of their unsaturation profile, directly influencing the nutritional quality of these oil, for example, with regards to quantitatively unsaturated fatty acids, as well as total carotenes. Thermal analysis has been used in studies on thermal decomposition, moisture determination, volatile compounds, thermal oxidation, reaction kinetics, crystallization, phase diagrams, specific heat determination, vitreous transition determination, storage time determination. And it can be useful to characterize the properties of the oils and fat foods. Oils are responsible for performing varied and important functions in the body, such as providing calories, essential fatty acids and fat soluble vitamins, and are considered very important among the ingredients and the sensory aspects of the functional properties of the food. The final characteristics of processed fat products depend on the physical and chemical properties of oils and fats present in their formulation.

Food adulteration has been practiced since a long time and sophisticated foods have increased in the last years. Foods and ingredients presenting high-value are the most vulnerable for adulteration. Determination of food authenticity and detection of adulteration have become an important question in quality control and safety of food products. Indeed, consumer awareness has increased about food quality and safety, geographical origin and agricultural. The replacement of original substance partially or completely with more easily available and cheap substance is the most common procedure performed by defrauders. Although the physico-chemical analyses are promising techniques to determine the authenticity of food products, they are time consuming and use several pollutant reagents. For these reasons, there is a need to develop rapid, inexpensive and efficient analytical methods for the detection of frauds and authentication of food products. Recently, more attention has been paid to the development of noninvasive and non-destructive techniques such as infrared, fluorescence, and so on. These techniques are fast, of relatively low cost, environmentally friendly, and provide a great deal of information with only one test, making them suitable for on-line and/or at-line process control. In addition, the above-mentioned techniques often require little or no sample preparation and are relatively easy to operate. The aim of the present study was to determine the potential of mid infrared and fluorescence methods combined with multivariate statistical analyses as fingerprints allowing authenticating different food products.

Flavonoids are a vast group of heterogeneous polyphenols with various health benefits, derived from secondary metabolism of plants. They are ubiquitously found in fruits, vegetables, tea, and wine. Chemically, flavonoids are classified into several subclasses among them are flavones (2-phenyl-4H-benzopyran-4-ones), aurones (structural isomers of flavones; 2-benzylidene benzofuran-3(2H)- ones) and 2-styryl chromones (vinylogues of flavones). Low molecular weight polyphenolic phytochemical flavonoids play important role in various biological processes at nontoxic concentrations in organisms. Therefore, flavonoids are important components of the human diet. Many natural products belonging to the flavonoid subclasses possess anticancer activity like quercetin and apigenin (flavones), hamiltrone (aurone), hamilcone (chalcone) and hormothamnione (styrylchromone). The role of dietary flavonoids in cancer prevention is well established and widely discussed. Many mechanisms of their action have been identified including cell cycle arrest, induction of apoptosis, inhibition of angiogenesis, antioxidant effect and inhibition of some functional enzymes like cyclindependent kinases, tyrosine kinases, aromatases, topoisomerases, glycogen phosphorylases and reversal of multidrug resistance or a combination of these mechanisms. Naturally obtained flavone moiety having a variety of biological activities can be taken as lead compound for the synthesis of synthetic flavone derivatives with different functional groups at different positions of flavone skelton.
