[57] [Problem] To provide a food containing live lactic acid bacteria that enables efficient intestinal delivery by ingestion without requiring costly processes or materials. [MEANS FOR SOLVING PROBLEMS] The present invention comprises a nucleic acid complex for protecting live lactic acid bacteria containing nucleic acid, one or more gelling agents and water from gastric juice, and a liquid containing live lactic acid bacteria is emulsified with an emulsifier and an oil. A nucleic acid complex mixture in which an emulsion and a live lactic acid bacterium containing the nucleic acid complex are protected, and an emulsion obtained by emulsifying a liquid containing a lactic acid bacterium live bacteria with an emulsifier and an oil and fat, the nucleic acid and one or more gels The present invention relates to a method for producing a nucleic acid complex mixture in which live lactic acid bacteria are protected by mixing with a nucleic acid complex containing an agent and water, and a method for protecting lactic acid bacteria from gastric juice. Preferred nucleic acid complexes are DNs in which the nucleic acid is particularly derived from biological waste. A and the gelling agent uses gelatin and carrageenan. Moreover, what uses lecithin as an emulsifier and cacao butter as an oil and fat is preferable. |
