Estimating the term…
A human food product comprises a higher ploidy strain of Fungi imperfecti of which each parent has a genetic growth constraint not shared by the other parent. One parent is for example auxotrophic for two compounds selected from histidine, arginine, leucine and adenine and the other for the other two. The nucleic acid content of the strain is preferably less than 2% by weight. The strain may be made by killing a higher ploidy strain of Fungi imperfecti and simultaneously reducing its nucleic acid content to below 2% by weight by treatment with water. The process may include preparing a higher ploidy strain of edible Fusarium by culturing two auxotrophs thereof together in a medium containing nutrients permitting both to grow and then culturing organisms derived from such culture in minimal medium. The invention is applicable to the production of human food by culturing the strain in conditions such that reversion or partial reversion to the haploid form(s) is minimised.
A human food product which comprises a higher ploidy strain of a member of the Fungi imperfecti of which each parent has a genetic constraint on its ability to grow which is not shared by the other parent.
A higher ploidy strain of Fungi imperfecti which is dead and of which the nucleic acid content is less than 2% by weight.
A process of producing human food which comprises culturing a higher ploidy strain of Fungi imperfecti of which each parent has a genetic constraint on its ability to grow which is not shared by the other parent, said culturing being carried out under conditions such that reversion or partial reversion to a haploid form is minimized and recovering the biomass produced, for use in human food.
Human food which comprises a higher ploidy strain of the Fungi imperfecti in which the fungus has been treated to remove nucleic acids and to modify its texture, taste or mouth feel.
