WHEY PRODUCTS AS WHEY PRODUCTS AS FUNCTIONAL FOODS FUNCTIONAL FOODS W. James Harper Department of Food Science & Technology The Ohio State University Functional Foods Functional Foods  Functional foods have been defined as “any food or food ingredient that may provide a health benefit beyond the traditional nutrients that it contains.” Functional Dairy Foods Functional Dairy Foods  In the early 1980’s, the Japanese were the first to recognize dairy components as having significant contributions to “physiologically functional foods.” Since then there has been an increasing number of investigations that have supported this view. Functional Dairy Foods Functional Dairy Foods  Current evidence for the health benefits of most dairy foods and dairy components is based primarily on in vitro and in vivo animal studies  Human clinical studies are still needed in many areas Significant Functions Significant Functions  Anti-microbial – including control of gut microflora  Anti-viral  Binding of E coli and cholera enterotoxins  Anti-cancer  Immunomodulation  Anti-oxidative  Opioid effects  Retard osteoporosis Cardiovascular Functions Cardiovascular Functions  Anti-inflammatory  Anti-hypertensive  Anti-thrombic  Cholesterol reduction Whey Products and Whey Whey Products and Whey Components Components with Bioactive Functions with Bioactive Functions WHEY PRODUCTS WITH WHEY PRODUCTS WITH POTENTIAL HEALTH BENEFITS POTENTIAL HEALTH BENEFITS  Whey Protein Concentrates – 34 to 85% protein  Whey Protein Isolates – Ion exchange and membrane processed  Whey Protein Fractions – Lactoferrin, Lactoperoxidase  Whey Protein Hydrolysates – Bioactive peptide concentrates  Whey Salts From Permeate – Enriched in calcium salts Almost All Milk Components May Almost All Milk Components May Contribute Potential Health Contribute Potential Health Benefits - Including Benefits - Including  Proteins  Peptides  Lipids  Minor Carbohydrates  Minerals  Vitamins AND AND Almost all bioactive milk Almost all bioactive milk components are found in components are found in whey whey [...].. .Whey Composition Component Sweet whey Acid whey Total solids 6.5% 6.4% Protein 0.6%` 0.54% Lipids 0.25% 0.05% Lactose 5.0% 4.5% Ash 0.52% 0.6% Lactic acid 0.14% 0.47% Sweet Whey Proteins Beta lactoglobulin 55% Alpha lactalbumin 15% Immunoglobulins 15% BSA 5% Lactoferrin .
