My explanation for corpse starch rations is that it's made from a corpse, but you're not literally eating human flesh.
Imagine a mortuary vault on a hive world, corpses spread out on slabs as far as you can see. Robed attendants walk between the slabs, sprinkling each corpse with fungal spores. Over the course of a week, the spores germinate, swelling into aggressive fungal growths leaching every possible nutrient from the corpse. At the end of the week all that remains of the corpse is a pile of dry bones, even the marrow leached away. The nutrient rich fungus is harvested, processed, and pressed into bricks of "corpse starch".
Imagine a vat the size of an olympic swimming pool, workers in heavy rubber suits and gas masks tipping corpses into a thick broth of chemicals and tailored bacteria. The broth bubbles and churns, breaking down each body into its basic biochemical components. The end result is a thick nutrient rich organic sludge ready to be processed into corpse starch, medicines, and raw material for vat grown tissue.

Not my thing, but still very cool to hear about.If you're going, let us know what it was like.
