Preparation method and application of chili particles

The invention discloses a preparation method and application of chili microparticles. The method comprises the following steps: cleaning fresh chilies, carrying out baking at low temperature, then carrying out differential pressure drying treatment, putting the dried chilies into an extraction kettle to carry out continuous extraction treatment, and separating chili residues from chili extract liquor for later use; carrying out superfine grinding on the chili residues, carrying out vacuum freeze-drying treatment on the chili extract liquor, and embedding the chili residues and the chili extract liquor with pectin to obtain the chili microparticles. According to the invention, chili dehydration is combined with differential pressure drying, and internal tissue binding force of chilies can be reduced, so that oil substances in the chilies are frozen and condensed, loss of nutritional ingredients of the chilies is reduced, and the preservation time of the chilies is prolonged; and moreover, the chili micro-parti
