Patent number: 11945954Abstract: The invention relates to a method for preparing high-stability liquid blueberry anthocyanins, belonging to the field of food processing. A method for preparing high-stability liquid blueberry anthocyanins comprises the following process steps: adding graphene oxide and chitosan to an MES buffer solution at room temperature, mixing homogeneously and adding EDC and NHS sequentially, reacting to obtain a first solution; adding dry blueberry anthocyanin powder in the first solution, adjusting pH to 4.5 to 5.0 and mixing homogeneously to obtain a second solution, and treating the second solution at 350 to 420 MPa and 2 to 4° C. to obtain the product. The method for increasing the stability of blueberry anthocyanins provided by the present invention uses dry blueberry anthocyanin powder as a raw material and adds graphene oxide combined with chitosan compound as an anthocyanin stabilizer, thereby increasing the stability of blueberry anthocyanins during processing and production.Type: GrantFiled: July 19, 2019Date of Patent: April 2, 2024Assignee: SHENYANG AGRICULTURAL UNIVERSITYInventors: Bin Li, Bo Xue, Ruihai Liu, Xianjun Meng, Ye Zhang, Yuxi Lang, Xulong Ran, Xu Xie, Zhihuan Zang, Weisheng Wang
