(CA1301682) THE EMBODIMENTS OF THE INVENTION IN WHICH AN EXCLUSIVE PROPERTY OR PRIVILEGE IS CLAIMED ARE DEFINED AS FOLLOWS: 1. Method for the production of a microbially encapsulated material, comprising: treating a grown intact microbe having a microbial lipid content of less than 40% by weight, with an encapsulatable material in liquid form which is capable of diffusing into the microbial cell without causing total lysation thereof, said treatment comprising contiguously mixing the microbe with the encapsulatable material liquid in the presence of an aqueous medium to produce an aqueous emulsion of the encapsulatable material liquid and to maintain the aqueous emulsion during the mixing, whereby the encapsulatable material liquid is absorbed by the microbe by diffusion across the microbial cell wall and the encapsulatable material is retained passively within the microbe, the method being performed in the absence of treatment of the microbe with a lipid-extending substance or a plasmolyser. 2. Method according to claim 1 wherein the microbe is selected from fungi, bacteria and algae. 3. Method according to claim 1 wherein the microbe is a fungus having a lipid content of up to 5% by weight. 4. Method according to claim 3 wherein the microbe is a fungus having a lipid content of up to 3% by weight. 5. Method according to claim 1, 2 or 3 wherein the microbe is a yeast. 16 6. Method according to claim 1, 2 or 3 wherein the microbe is selected from Saccharomyces cerevisiae, Candida utilis, Aspergillus niger and Kluyveromyces fragilis. 7. Method according to claim 1, 2 or 3 wherein the microbe is alive at the commencement of the contiguous mixing. 8. Method according to claim 1, 2 or 3 wherein the microbe has an average cell diameter of greater than 5 microns. 9. Method according to claim 1, 2 or 3 wherein the encapsulatable material has a benzene or a naphthalene ring. 10. Method according to claim 1, 2 or 3 wherein the encapsulatable material is selected from benzaldehyde, essential oils used in flavours or fragrances, pheromones, organophosphorus insecticidal compounds, leuco dyes, menthol, lauryl ether sulphate, alphachloralose, dichlorophen, onion extract, oil of wintergreen, and water-soluble food colourants. 11. Method according to claim 1, 2 or 3 wherein the encapsulatable material is an essential oil selected from garlic, clove, mint, peppermint, lavender, cedar and eucalyptus oils. 12. Method according to claim 1, 2 or 3 wherein the contiguous mixing is performed at an elevated temperature in the range 35[deg.]C to 60[deg.]C, at least during the initial stage of the mixing. 17 13. Method according to claim 1, 2 or 3 wherein the treatment is performed for a time until the desired optimum amount of one or more globules of the material can be observed (microscopically) within the microbial cell. 14. Method according to claim 1, 2 or 3 wherein the resulting microbial capsule is harvested and then subjected to heat-treatment. 15. Method according to claim 1, 2 or 3 wherein the microbe is a filamentous fungus. 16. Method according to claim 1, 2 or 3 wherein the resultant microbially encapsulated material is separated from the residual method ingredients by spraydrying. 17. A microbial capsule being a grown intact microbe selected from fungi, bacteria and algae, having a microbial lipid content of less than 40% by weight and having encapsulated therein a material which has been absorbed by the microbe by diffusion across the microbial cell wall as a result of contiguously mixing the microbe with the encapsulatable material in liquid form in the presence of an aqueous medium to produce an aqueous emulsion of the encapsulatable material liquid and to maintain the aqueous emulsion during the mixing, in the absence of treatment of the microbe with a lipid-extending substance or a plasmolyser. 18 AAS/ML - ADL 1121
