The process consists of making available the full contents of the rumen or paunch of commercially slaughtered cattle without any dilution or addition of substances thereto. Said contents per se are subjected to mechanical separation to remove up to 90% of the watery and liquid contents therefrom. The premium, relatively solid material left is in the form of clumps of matted fibers having other solids and semi-solids adhering thereto, such as cogulants, emulsions, and fat globules. Said matted and solid fraction is chopped or otherwise subdivided, rendering the separated particles more susceptible to the next vital step of flash-drying. Flash-drying of said fibrous, premium fraction is preferably carried out by a combined heating and conveying medium which applies a blast of high temperature air upon and through the divided fibrous fragments and particles while they are tumbled and dispersed. Such products contain protein (by weight) in a range from 10 to 12%; fats in range from 3.3 to 3.8% and carbohydrates in a range from 70 to 80%. The extent and intensity of flash-drying may be varied to produce products varying in moisture content from 2 to 60% by weight.
