The Evolution of Dairy Processing

THE EVOLUTION OF DAIRY PROCESSING Total carbon footprint from the cheese sector (both cheese and whey) is approximately 54 million metric tons (MMT) of CO e, or 0.7 percent of the total GHG emissions in the U.S. The entire dairy industry - farm to glass - contributes approximately 2% of the total U.S. GHG emissions. HERE'S A LOOK AT TECHNOLOGY THAT HAS TURNED WHEY INTO PRODUCTS WE USE EVERYDAY U.S. CHEESE AND WHEY CARBON FOOTPRINT Raw Milk Transport 1.9% Manufacturing 10.7% Packaging 1.3% Distribution 3.0% Farm 46.5% Retail 8.3% Consumption 6.9% Feed Production 22.4% WHEY IS NO LONGER WASTE 10 pounds of milk is needed to create one pound of cheese. 9 pounds of whey was historically a waste product. Here's how technology has changed that: DAIRY PROCESS DIAGRAM Whey Casein/Whey Lactose Concentration Demineralization Fractionation RO Polisher Effluent Discharge Casein Concentrated Lactose On-Site Waste Management Whole Milk Cheese Production Cheese Whey Whey Protein Concentration WPI Effluent Production RO Polisher Discharge Procream Fat Removal WPI 90 On-Site Waste Management Spray Dry CURRENT USES OF WHEY Body Building How whey is used for body building: 1. Cow is milked and the raw milk is cooled at 4°C 2. Milk is pasteurised at 72°C - 73°C and recooled. Milk undergoes cheese processing and whey is drained off. 3. Whey is processed, filtered, and micro-filtered to become WPC (whey protein concentrate) or isolate. 4. Finally it's sprayed dried to make whey protein powder. Electricity Production How whey is used to generate electricity: 1. Yogurt production plants have leftover whey that's usually shipped to farms for fertilizer. 2. The leftover whey is now put into a large tank filled with anaerobic bacteria (anaerobic digester). 3. The whey is then converted into electrical power to produce combustible methane gas fuel. Food Ingredient How whey is used in food ingredients: 1. Whey protein concentrate (WPC) in liquid form, as well as powder, is a highly digestible form of protein used in numerous food related products including ice cream, candies, baked goods, and baby formula. Whey protein has been used as fat replacers for low-fat ice cream and as an ingredient in milk replacement products. Whey protein is also a popular dietary supplement for improving muscle strength and body composition and for the prevention of heart disease, diabetes, and age-related bone loss.
