    • The present invention provides a method for producing a material dispersed with ultraviolet shielding fine particles, characterized by subjecting a starting material liquid mixture comprising particles comprising one or more inorganic substances having shielding abilities against ultraviolet light, one or more silicone dispersants selected from modified silicones and reactive silicones, and a silicone oil to a mill treatment and/or a high-pressure dispersion treatment; and ultraviolet shielding fine particles or a material dispersed therewith, characterized by being produced by the above method. Also, the present invention provides a method of producing a powdery product of ultraviolet shielding fine particles, characterized by drying the material dispersed with ultraviolet shielding fine particles obtainable by the above method. Further, the present invention provides cosmetics comprising a material dispersed with ultraviolet shielding fine particles or a powdery product of the ultraviolet shielding fine particles. The material dispersed with ultraviolet shielding fine particles of the present invention is characterized in that the ultraviolet shielding fine particles comprise particles comprising one or more inorganic substances having shielding abilities against ultraviolet light, surfaces thereof being coated with one or more silicone dispersants selected from modified silicones and reactive silicones, and that at least a part of the ultraviolet shielding fine particles is dispersed in a silicone oil as aggregated particles of the particles comprising inorganic substances.

    • An enzyme-treated hesperidin, comprising alpha-glucosyl hesperidin, hesperidin and beta-monoglucosyl hesperetin, wherein the content of hesperidin is 0.1 part or less by weight; and that of beta-monoglucosyl hesperetin, 0.1 to 0.5 part by weight, on the basis of 1 part by weight of alpha-glucosyl hesperidin. The present invention also provides a process to produce enzyme-treated hesperidin, which comprises subjecting a solution containing alpha-glucosyl hesperidin and intact hesperidin to alpha-L-rhamnosidase to convert the intact hesperidin into beta-monoglucosyl hesperetin. The enzyme-treated hesperidin, which is excellent in water solubility and is free from crystal precipitation (clouding) even if stored for a prolonged period of time, can be produced from a material containing alpha-glucosylhesperidin and hesperidin by conducting the above simple treatment of material. The present invention further provides a method of using the enzyme-treated hesperidin. The enzyme-treated hesperidin can be used in the prevention of clouding of a canned tangerine and prevention of fading of natural coloring matter.
    • 一种酶处理的橙皮苷,其包含α-葡糖基橙皮苷,橙皮苷和β-单葡萄糖基橙皮素,其中橙皮苷的含量为0.1重量份或更少; 基于1重量份的α-葡萄糖基橙皮苷的β-葡萄糖基橙皮素0.1〜0.5重量份。 本发明还提供了一种生产酶处理的橙皮苷的方法,其包括将含有α-葡糖基橙皮苷和完整的橙皮苷的溶液经受α-L-鼠李糖苷酶将完整的橙皮苷转化成β-单葡糖基橙皮素。 通过进行上述简单的处理,可以通过含有α-葡萄糖苷基和橙皮苷的材料来生产即使长时间贮存也具有优异的水溶性并且没有晶体沉淀(混浊)的酶处理橙皮苷 材料。 本发明还提供了使用酶处理的橙皮苷的方法。 酶处理的橙皮苷可用于防止罐装橘子的混浊和防止天然色素的褪色。
