Preparation and food using the manufacturing apparatus and compositions thereof elution methods and oil composition of the oil-soluble active ingredient and powdered fat composition

A citrus oil-soluble contained in the pericarp or leaves active ingredient oily composition was the method and the elution is effectively eluted without degrading the edible oil or powder fat composition and their preparation and their manufacturing apparatus and provide a food with those compositions. A mixture of citrus peel or leaf and oil, heat treatment in an oxygen-free state by superheated steam, elution method of the oil-soluble active ingredient is eluted oil-soluble active ingredient in an edible oil. Further, the production method of the oil-based composition for producing a liquid portion was separated oily composition after the heat treatment. Further, a saturated steam generator, a superheated steam generating means, and a temperature control means of the superheated steam, mixed charged and citrus peel or leaf and oil, elution for eluting the active ingredient in an edible oil and processing container, consists of a separating means for separating the liquid portion from the elution processed material after processing, the manufacturing apparatus of the oily composition to produce an oily composition containing the active ingredient of citrus peel or leaves. .FIELD 6
