How can I estimate the nutritional content of my home-made walnut milk?
You can send it out to a laboratory to be analyzed, but it’s not cheap; it takes a rather complex battery of tests. So if you want to take a best estimate, you should start with the nutrition information for walnuts. From there, you look at two categories of nutrients: water-soluble and fat-soluble. Vitamins B and C are water-soluble, and you can assume that most of them have made it into your walnut-milk if you’ve given them a chance to get in there (by whomping it in a food processor good and hard). The fat soluble vitamins are harder to estimate. When you whomp it up, some of the fat from the nuts will be emulsified into the water, and will remain after you strain it. It will bring vitamins like A, D, and E with it. But’s hard to guess how much without a laboratory analysis. It’s going to be “low” using a standard home food processor; a commercial device for the same purpose is going
