Abstract: 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.

Abstract: The disclosure relates to bacillus having an effect of inducing corn to resist Northern leaf blight and applications of the bacillus. The bacillus having an effect of inducing corn to resist Northern corn leaf blight is Bacillus megaterium which was deposited on Apr. 16, 2019 with a deposit number of CGMCC No. 17573. The Bacillus megaterium of the disclosure can induce corn to generate resistance to Northern corn leaf blight during seed germination and corn growth to activate the immune response of corns and stimulate immune control of Northern leaf blight of corn. The method described herein is long in coming does not pollute environment and soil, is a green, simplified and new control method of Northern leaf blight of corn, and has wide application and popularization prospect.
