Building on Wisconsin’s tradition as the “Dairy State,” the center explores functional, flavor and physical properties of cheese/cheese products and other milk components used as ingredients and as finished products. CDR research focuses on innovation, technology, and product development for cheese, dairy ingredients, cultured products and beverages, in addition to dairy protein processing/ separation procedures, use of cheese and dairy ingredients in foods, processes involving fractionation, concentration or drying of milk, whey and whey proteins, and technologies for product safety and quality. More than 30 researchers and scientists are involved in conducting basic and applied dairy research. Collectively, the CDR staff has over 250 years of food industry experience, which creates a unique mix of academic and industry perspectives to help address any challenges facing the dairy industry. The facilities (including a pilot plant) and equipment are extensive, allowing the center to not only create new products, uses and processes, but also to meet the unique needs of the food industry. Annually, the CDR provides specialized training and short courses to over 1,400 industry personnel. RESEARCH FOCUS • Explore and understand the functional properties of cheese, cheese products and cultured dairy products • Functional dairy proteins (casein alternatives, milk protein concentrate (MPC), modified whey protein concentrate (WPC), etc.) and milk ingredients • Dairy food safety and quality systems • Dairy processing (membrane filtration, drying, separation, etc.) 39 WISCONSIN CENTER FOR DAIRY RESEARCH 40 CHEESE The University of Wisconsin-Madison has a long and proud history of cheese research and outreach. The CDR extends the art and science of cheese making into the realm of specialty cheese innovation, as well as cheese as an ingredient. Its licensed cheese makers/scientists provide industry with training programs, research facilities, cheese making protocols for specific end use, and leading-edge technologies for adjusting the texture, taste and/or functionality of cheese in food applications. The CDR cheese making pilot plant is located within the University of Wisconsin-Madison Dairy Plant, a licensed, operational dairy. This setting allows for flexibility in all aspects of the cheese making process. The facility is designed for manufacture of any retail cheese variety (fresh, cream, cottage, hard, soft, semisoft, surface-ripened, molded and eyed), process cheese and cheese food, plus cold pack. CDR cheese applications staff, through consultation, pilot plant trials, applications laboratory evaluation, and on-site trials and visits, works in a confidential manner with all entities of the dairy industry. From dairy producers and manufacturers to ingredient suppliers and equipment manufacturers, applications staff works with the entire cheese distribution system, including foodservice, retail, wholesale, brokers, converters, warehouses, executive chefs and quick-service restaurants — wherever cheese is used in food application systems. Staff members also provide direct technical support for the end user of natural, process and cold pack cheeses, as well as cheese in food applications. DAIRY PROTEIN/INGREDIENTS CDR has an extensive program focusing on dairy ingredients. Working on a confidential basis, the program strives to meet the needs of regional and national dairy ingredient processors and food manufacturers. These needs include process, product and applications support. The dairy ingredient program and applications lab offer technical support for whey, buttermilk, nonfat dry milk, permeate, whey protein concentrate (WPC), whey protein isolate (WPI), individual whey proteins, milk protein concentrates (MPC) and isolates, milk protein fractions and native whey protein. Services include information, training, seminars, process development, process troubleshooting, ingredient functionality testing and prototype development. Application areas of expertise are beverages, baked products, confections, dairy products, energy bars and prepared foods. ANALYTICAL SERVICES Analytical services are offered to support projects carried out at the Wisconsin Center for Dairy Research. CDR provides comprehensive chemical and microbiological testing services and follows EURACHEM-CITAC Guide CG-2 as quality assurance guideline of nonroutine and R&D analysis of samples. Tests performed include crude protein, casein, true protein, milkfat, total solids, mineral content by reference methods, enzymatic determination of lactose and galactose, protein profiles of milk and milk products by capillary electrophoresis, cheese proteolysis and determination of particle size analysis. Rheological tests performed include texture profiles, cheese meltability and functional properties of milk products. Microbiological dairy food safety and quality tests are routinely determined, including tests for coliforms, standard plate count, plus yeast and mold. Shelf life and microbial challenge studies also are performed. 41 WISCONSIN CENTER FOR DAIRY RESEARCH SAFETY/QUALITY APPLICATIONS Providing an active approach to safety and quality, the CDR staff conduct multiple training workshops for industry each year in addition to performing audits of dairy facilities, solves problems for dairy plants and reviews dairy facilities’ good manufacturing practice (GMP) programs. CDR staff works with facility personnel to improve their GMP program and establish or modify an HACCP program. Staff members also interpret government regulations related to specific dairy products and dairy facilities and provide technical expertise in HACCP (including FSMA) implementation and compliance with the Committee for the Assurance of Wisconsin Dairy Product Safety requirements. In addition, cheese and dairy ingredients produced at CDR are monitored for microbial safety. SENSORY ANALYSIS This area designs, conducts and summarizes sensory analysis of cheese and dairy ingredients, using modern sensory testing approaches including the use of FIZZ Networks software with trained panelists performing a wide range of consumer and quantitative tests to meet the customers’ needs. Evaluations include flavor, body/texture and appearance profiles, as well as cheese functionality for shredding/slicing and cooking applications. Panels conducted range from trained to focus group, from descriptive to consumer. FACILITIES AND EQUIPMENT The CDR pilot plant facilities meet the needs of the dairy and food processing industry by offering access to smaller-scale equipment. The small-vat new product development capability in the cheese pilot plant helps evaluate new cheese making processes. The dairy ingredient pilot plant has the capability to perform milk and whey processing of all types to produce beverages, yogurt, ice cream, sauces, spreads, dips and salad dressings. In addition, the applications lab at CDR has equipment to test the functionality of cheese as an ingredient, including a full line of foodservice pizza ovens. CDR also can evaluate the functionality of dairy ingredients and formulate dairy ingredients into baked products and confections. The chemical and microbiological laboratories extend more than 5,000 square feet and offer some unique testing capabilities. 42 WISCONSIN CENTER FOR DAIRY RESEARCH FACILITIES AND EQUIPMENT WISCONSIN CENTER FOR DAIRY RESEARCH/UW-MADISON PILOT PLANT EQUIPMENT CONTACT: THOMAS SZALKUCKI Wisconsin Center for Dairy Research firstname.lastname@example.org 608-262-9020 EQUIPMENT: Full cheese making manufacturing line located in a state-licensed, state-inspected, operating dairy manufacturing facility.
