Hi, if you look at the papers that calculate the acidity of foods (which basically come up with fruits and plants basic, grains and meat acidic) they calculate just the mineral/ion concentration and add them up. Acidity mostly comes from high phosphorus, unbalanced by minerals from the left hand side of the element table. Much to my surprise, cheese is the most acidic of all classes of foods, while milk or yogurt are near neutral. And the difference is the whey. The organic acids you talk about do not really count, as, e.g., citric acid inside the animal reverts to alkaline compounds (bicarbonate). Look for acid renal load in scientific papers. The table is in a paper by Remer and Manz but is behind a paywall.I think this would be pretty acidic with having added vinegar to the milk.
I'm seeing condensed and evaporated milk in those pages,Pages 25 - 28
Other sources say the vacuum drying method is older than the current two common methods.
Oh, yea.... give it to the chickens. They LOVE it! I just pour it as is in a pan for them, and they drink it like water.So, I periodically make acid-set cheese from discount milk and end up with several quarts of whey remaining.
I can use a quart to make bread if I have guests (I'm on a low-carb diet so I need to feed bread to other people so I don't eat it all).
I can drink a cup or two (hot, with salt and pepper). No one else will drink it.
I hate pouring it down the drain, so ...
Can I use it up in any useful quantity making mash for my chickens? Mixing it with feed and/or scratch?
Especially, if I mix it with scratch will it help improve the nutritional quality? I only give scratch once or twice a week -- mainly as a training treat or to help the integration process by letting all chickens have a treat together. When I give scratch I often mix it with things like scraps from soup-making.
This is the best nutritional info I've found, but I don't know if the sodium content reflects mine because I don't salt the milk before making the cheese, preferring to salt the cheese afterward.
With my math disability I get lost in feed analysis numbers beyond simple things like % protein and grams of carbs.
