This invention belongs to the field of display materials technology, and relates to a low-reflectivity black dispersion and its preparation method. The low-reflectivity black dispersion comprises the following components in parts by weight: 15-20 parts organic black pigment, 1-5 parts blue pigment, 1-5 parts red pigment, 0.1-2 parts red derivative, 0.1-2 parts black derivative, 3-6 parts dispersant, 3-6 parts acrylic resin, and 54-78 parts solvent. This invention uses organic black pigment to replace carbon black as the black matrix, adds blue and red pigments to reduce the reflectivity of the organic black photoresist composition film, and adds red and black derivatives to improve dispersion stability and reduce the viscosity and particle size of the dispersion. The low-reflectivity black dispersion of this invention has small particle size and stable dispersion, reducing the reflectivity after film formation while maintaining blackness.

This invention provides a high-satiety chicken small molecule peptide and its application in chicken meal replacement powder. First, a gastric self-expanding microsphere is prepared, with yeast β-glucan and hydroxypropyl methylcellulose as the wall material and modified chicken small molecule peptide as the core material. The microsphere absorbs water and expands in the acidic environment of the stomach, generating a feeling of fullness. In the intestinal environment, it slowly releases the modified chicken small molecule peptide, promoting absorption and regulating intestinal health. Furthermore, solid-state fermentation of mixed grain powder using Aspergillus oryzae is used to prepare the chicken meal replacement powder. The addition of the gastric self-expanding microsphere and fermented mixed grain powder further enhances satiety, meeting the market demand for healthy meal replacement foods.
