PROBLEM TO BE SOLVED: To provide a treatment method of a squeezed liquid of a plant in which the squeezed liquid is postprocessed more efficiently without uselessness by completing a process technique in which the squeezed liquid of the plant is more effectively processed, and the squeezed liquid is achieved as a higher value-added product.SOLUTION: In the squeezed liquid of a plant, though fiber is few, fleshy particles of leaves or stems exist together a lot, thereby the squeezed liquid directly or after filtered by a filter is distilled to obtain a distillate of the squeezed liquid of the plant, and the distillation is controlled so that a residual concentrated liquid of the distillation may remain in the bottom of a distillation container after the distillation to thereby obtain the distillation residual concentrated liquid, and is combined with the distillate to produce a raw material or an additive for foods, cosmetics, a skin treatment agent or the like.COPYRIGHT: (C)2012,JPO&INPIT【課題】植物の搾汁液をさらに効果的に処理する手法を完成することにより、無駄無くより効率的に搾汁液を後処理して、搾汁液をより付加価値の高い製品として実現する。【解決手段】植物の搾汁液には、繊維質は少ないが、葉や茎の肉質の粒が多量に混在しているため、搾汁液をそのまま又はフィルターで濾過してから蒸留することによって、当該植物の搾汁液の蒸留液を得ると共に、蒸留後に蒸留容器の底部に蒸留残り濃縮液が残るように蒸留を制御することによって、積極的に蒸留残り濃縮液を得て、前記蒸留液と併用して、食品や化粧品、皮膚治療剤などの原料ないし添加物として製品化できる。【選択図】図3
