  • Patent number: 4818268
    Abstract: An osmoprotectant particle for use in enhancing fungus growth and particularly for use with edible mushrooms. The osmoprotectant particle includes a carrier particle, either a protein or a neutral material and a plurality of osmoprotectant microdroplets containing water soluble phosphoglyceride such as hydroxy lecithin and betaine or choline which are attached to a plurality of recesses formed about the carrier particle. Denaturation of the protein and/or control of a surface-to-volume ratio restricts access to the microdroplets such that only mushroom mycelia occuring in the later flushes will be able to utilize the phospholipid droplets. A method is provided for producing the osmoprotectant particles utilizing either the protein carrier particle or the neutral carrier particle.
