Skim milk, butter-derived aqueous phase, butter oil, and fish oil (3 levels) were used to produce UHT pasteurized n-3 fatty acid-fortified beverages (3.1% fat, 3.9% protein, and 11.5% total solids) with targeted deliveries of 200, 500, and 800mg of eicosapentaenoic acid and docosahexaenoic acid (combined total) per 250mL (8 fl oz) serving. Microbial quality, emulsion stability, and oxidation of lipids over 35d of storage at 4°C were evaluated. Conjugated diene hydroperoxides were below 1% throughout storage and were found at highest concentrations around d 21 of storage for all formulations. Volatile analysis indicated an increase in 1-penten-3-ol in the n-3 fortified dairy-based beverage systems during storage. Triangle tests were conducted to determine if consumers could detect a difference in aroma, compared with commercially processed aseptically packaged milk. The beverage system with targeted delivery of 500mg of eicosapentaenoic acid + docosahexaenoic acid per 250-mL serving was not different in aroma compared with commercially available UHT processed milk. This formulation delivered 432mg of heart-healthy n-3 fatty acids per 250-mL serving on d 35 and was microbiologically and physically stable throughout the 35-d refrigerated storage period.

Not as good as having the cows eating greens, but much better than nothing

  25 volunteer participants who sampled one-ounce cups of regular 2% milk in comparison to samples of skim milk that contained 78 parts of butter oil to 22 parts of fish oil. "We couldn't find any aroma differences,"
  Could fortify the milk with up to 432 milligrams of fatty acids per cup without causing a detectable difference
