The invention relates to a
solid beverage for maintaining intestinal-brain axes as well as a preparation method and application of the
solid beverage, and belongs to the technical field of
food processing. The health-care tea
powder consists of cold-extracted freeze-dried tea
powder,
theanine powder,
fructus phyllanthi powder, PQQ powder or microencapsulated PQQ powder, targeted
probiotic microcapsule powder,
mogroside and
galactooligosaccharide. During preparation, the cold-extracted freeze-dried tea powder, the microencapsulated PQQ powder and the purchased targeted
probiotic microcapsule powder are respectively prepared and then are mixed with other raw materials. The innovation of the invention lies in that the intestine-brain axis is synergistically maintained through a four-dimensional mechanism of anti-inflammatory and anti-oxidation-
neuromodulation-mitochondrial activation-
flora intervention, and the activity of the components is guaranteed by adopting technologies of cold extraction freeze-
drying, microencapsulation and the like. The
system can inhibit
enteropathogenic bacteria, repair intestinal barriers, protect nervous systems, improve cognitive functions and regulate intestinal
flora, has high
technical feasibility and market prospects, and makes remarkable progress compared with the prior art.
