A liquid solid separation apparatus having a porous metal pipe sealed inside a non-porous metal pipe which allows a portion of the liquids, e.g., hydrocarbons and water to pass through the first pipe into the non porous pipe from which they are removed while solids are retained within the porous pipe. In the process there is a system pressure which aids in the filtration and a circulating velocity which removes the detained solids. Preferably a portion of these solids with reduced liquid content are recycled back to the system, mixed with fresh feed. By recycling a porion of the recovered solid concentrate the velocity of the flow in the system kept constant and the system itself is stabilized.

The preparation of an edible substance for use in a foodstuff is described which comprises fungal cells of the order Mucorales. The cells are grown in a fermentor vessel in an aqueous liquid which is mixed during fermentation, and fermentation allowed to finish. The fungal cells are kept in the vessel and allowed to ripen, the cells' own RNAses reducing the intracellular RNA content. Fungi of this order may thus have a low RNA content and therefore no heating step, to reduce their RNA content, is necessary. The fungal cells are removed and processed into the edible substance. This substance is then processed into a foodstuff. This avoidance of heat has also resulted in better tasting foodstuffs.
