Homemade Vitamin C was today’s project. The urban homestead has a lemon tree and a grapefruit tree, so we have lots of raw material. We have never used any pesticides on the trees, so this stuff will be all organic! I have always felt wasteful throwing all those peels away. To find out I could have been making Vitamin C, among other things, out of them, made me very happy.
We eat grapefruit every morning, so afterward, I take the peels and scrape out the remaining fruit and membrane, leaving the white pith.
Then I slice the peels very thin and lay them on a baking sheet. When I have a full sheet (not more than a day or two) I turn the warming oven on to 150F and dry them for an hour or 2. Then I turn the oven off and leave them in there while it cools. After all that, if the peels are crispy and snap when I break them, I go on to the next step. If not, I repeat the drying process.
Here in Southern California, the humidity is such that if the peels sit for too long, they start to mold. So drying them in the oven is a must.
Next, the dried peels are placed in the high-speed blender and ground as fine as it will get them. This is fairly powdery, but there do remain a few chunks. I put the powder into a pint or quart jar and add a paper napkin or small piece of paper towel, to absorb any moisture.
This is a new project, so I am not sure if mold is going to be a problem. My sources say the powder should last about 3 months on the shelf and 6 months in the freezer. Hopefully, I will get enough made to last from final harvest to the following season’s first fruits.
I stir a teaspoon of this into my carrot juice in the morning. Sometimes 2t if I have a cold. Seems to work great. The rest of the family is not excited about the taste, so I am going to mix it with some raw honey and make little pills for them to try.
