    • An object of the present invention is to provide a high-quality anthocyanin pigment composition more efficiently and at a lower cost than red cabbage pigment, which has not been achieved by the prior art.
      This invention provides the following anthocyanin pigment composition derived from a plant other than red cabbage, the composition having the following features (A), (B), and (C):
      (A) an aqueous solution containing the anthocyanin pigment composition and adjusted to a pH of 3 with a citrate buffer (pH: 3.0) has a maximum absorption wavelength in the range of 500 to 550 nm in the visible light region;
      (B) when a pigment-composition-containing aqueous solution containing the anthocyanin pigment composition, 0.2 mass% citric acid, 20 mass% ethanol, and water is prepared so as to have a color value E 10%i 1cm of 10, 1 mL of the aqueous solution is sealed in a 20-mL vial, and the vial is stored at 50°C for 5 days and further maintained at 40°C for 30 minutes, the total amount of methyl mercaptan, dimethyl disulfide, and dimethyl trisulfide in the gas in the sealed space of the vial is 100 pg/mL or less; and
      (C) the gas in the sealed space of the vial contains 5-methylthiopentanenitrile when the vial is maintained at 40°C for 30 minutes in (B) above.
    • 本发明的一个目的是提供一种比现有技术所没有的红甘蓝颜料更高效且成本更低的高品质花色素苷颜料组合物。 本发明提供下述特征(A),(B)和(C)的组合物来源于红甘蓝以外的植物的以下花色素苷颜料组合物:(A)含有花色素苷颜料组合物的水溶液, 用柠檬酸盐缓冲液(pH:3.0)的pH为3时,在可见光区域中的最大吸收波长为500〜550nm; (B)将含有花色素苷类颜料组合物,0.2质量%柠檬酸,20质量%乙醇和水的含有颜料组合物的水溶液调制成色值E10%i1cm为10时, 水溶液密封于20mL小瓶中,将小瓶在50℃下保存5天后,进一步在40℃下保持30分钟,气体中的甲硫醇,二甲基二硫醚和二甲基三硫醚的总量 在小瓶的密封空间内为100pg / mL以下; 和(C)当小瓶在上述(B)中保持在40℃30分钟时,小瓶的密封空间中的气体含有5-甲硫基戊腈。
