Phycobiliprotein is a group of colorful and fluorescent water-soluble pigment that exists in the chloroplast surface of red algae, cyanobacteria and cryptomonad. Its function is to assist the photosynthesis by effectively enhancing the light energy conversion efficiency of photosynthesis, it can strengthen the competitive nature of such species. Based on one kind of originally edible natural red algae, the characteristic of its phycobiliprotein in converting ultraviolet energy into another fluorescent light is utilized to achieve the effect of preventing the skin tissue from damage by short wavelength light irradiation and color cosmetics. The method comprises the following steps: through an ordinary extraction method, the originally edible natural red algae are disaggregated into phycoerythrin. With the property of phycoerythrin in converting ultraviolet energy into another fluorescent protein and the emanating feature, phycoerythrin with appropriate color value is used as raw material and added to cosmetics, beauty product and skin care supplies of any color, wherein the ultraviolet energy can be converted into orange-red fluorescent for emanating, thus preventing the skin tissue damage due to short wavelength light irradiation and reflecting fluorescent colors to achieve the effect of make-up.藻蛋白(phycobiliprotein)是一群色彩鮮麗且具有螢光的水溶性色素。存在於紅藻、藍藻與隱藻類的葉綠體表面,其功能是輔助光合作用,將光合作用吸收之光能量轉換效率有效提升,可強化此類物種之競爭性。一種藉由一原本可食用之天然紅藻,利用其螢光蛋白具有將紫外線的光能量轉換成為另外一種螢光的特性,達到皮膚組織避免受到短波長光線照射的傷害;與達到彩妝之效果。該方法包含下列步驟:將原本可食之天然紅藻,透過一般之萃取方法,隔離出簡稱「藻紅素」之藻紅螢光蛋白。透過藻紅螢光蛋白具有將紫外線的光能量轉換成為另外一種螢光的形式,散發出去的特性。以適當之色價之藻紅素為原料,加添於任何顏色的一化妝品。一美容產品。一護膚保養用品。中,可將紫外線能量轉換成為橘紅色螢光形式發散出來,達到皮膚組織避免因受到短波長光線照射而受到傷害;與反射出所需之螢光色彩,達到彩妝之效果。相關專利說明:藻紅素吸收光譜:
