Food from before P-Day
After P-Day, and the power going out pretty much nation wide, most food stores began to spoil and rot quick enough to be made unusable due to lack of refrigeration. Anything that wasn't tightly sealed also stand the risk of getting infectious fluids in it. Foods such as meats, milk, butter, eggs, and similar went bad within the day without being kept cold. Without proper seals, any opened packages eventually came in contact with contamination. For the first few months, people made due and lived off of food stores that they had, or salvaged unspoiled, sealed foods from anywhere near by. As these supplies dwindled, other food sources soon became needed.
"""Nanites and Food"""
With a dwindling food supply and no real way to get more food outside of trading, people took to less conventional means to keep their bellies full. Breast milk and semen becoming good substitutes for actual food to the ferals, those with more refined tastes, and less likely to suck their meal from another in such a way, needed something else to substitute. For this Zephyr had a plan. Using the same nanite technology the resulted in mass transformations, they were able to convert base materials on hand into more pleasing and standard foods. After purifying the materials, often the excessive breast milk or cum of another, the product could be ran through another process to change it into just about any standard food item required, using different combinations of nanites for each kind of food. This procedure insured that a steady supply of edible product was available for consumption till other methods became viable, including trade and farm production.
