1. A translucent flavor nanoemulsion comprising:
a flavor oil phase,
an aqueous phase, and
a surfactant system comprising a first lecithin, a second lecithin, and free fatty acid being 10% or less by weight of the surfactant system,
the first lecithin having an HLB of 1 to 8,
the second lecithin having an HLB of 12 to 15 and comprising phosphatidylcholine and lysophosphatidylcholine 30% or greater by weight of the second lecithin, the phosphatidylcholine and lysophosphatidylcholine being at a weight ratio of 0.8:1 to 3.3:1,
the weight ratio between the first and second lecithins is 1:10 to 10:1,
wherein the nanoemulsion is free of any non-natural surfactant including sugar esters of fatty acids and polyglycerin fatty acid ester.
