The invention discloses a preparation method of a high-stability green pea
hull food base material, and relates to the technical field of
food processing. The method comprises the steps of
steaming and
blanching for color protection, wet-process
superfine grinding, composite enzymolysis, blending, high-pressure homogeneous
colloid milling, microencapsulation and the like, by optimizing all technological parameters, the
chlorophyll dissolution rate is increased by adopting 120-DEG C steam
steaming and
blanching for
enzyme deactivation and color protection, the
chlorophyll dissolution rate is increased by combining wet-process
superfine grinding with composite enzymolysis, and the stability is improved by adding
cyclodextrin,
konjac glucomannan and
carrageenan compound stabilizer. And refining the material by a high-pressure homogeneous
colloid mill, and finally carrying out
spray drying and microencapsulation to obtain the product. The prepared food base material can effectively retain the natural
turquoise color of the pea hulls, has excellent
thermal stability and long-term storage stability, is simple in process, green and
environmentally friendly, free of
chemical synthesis additives, suitable for industrial large-scale production and wide in application prospect in the field of
food coloring.
