Process for manufacturing lysed cell suspension

The invention pertains to a process for manufacturing a lysed cell in oil suspension with a solids content of at least 10 wt.% and a particle size Dv90 of 100 to 300 microns, comprising the steps of a) adding a first portion of microbial cell matter to an oil, b) subjecting the mixture of microbial cell matter and oil to one or more shear steps to effect lysis of at least part of the cells and produce a suspension comprising lysed cells in oil, c) adding a further portion of microbial cell matter to the suspension comprising lysed cells in oil, d) subjecting the mixture of microbial cell matter and the suspension comprising lysed cells in oil to one or more shear steps to effect lysis of at least part of the cells and produce a further suspension comprising lysed cells in oil. In one embodiment, the microbial cell matter has a water content of less than 10 wt.%. The invention pertains to a new lysed cell in oil suspension having a solids content of at least 10 wt.% and a particle size Dv90 value of 100 to 300 microns. The lysed cell in oil suspension produced by the present method generally has at least 70%, at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, or at least 98% cell lysis. The invention pertains to a composition comprising the lysed cell in oil suspension and one or more components useful in a feed. The invention also pertains to a feed product comprising the composition, to a method for manufacture of a feed product, to a method of raising an animal comprising feeding an animal the feed product and to a method of sustainably producing a meat product by feeding an animal the feed product.
