Technical Field

The invention relates to the technical field of nutriment manufacturing, and particularly relates to a quinoa peptide-based calcium supplement powder for children and a preparation method thereof.

Background

Chenopodium plant belongs to dicotyledonous plant of Li family, plant height varies from tens of centimeters to three meters due to different growth conditions, plant is broom-shaped, root system is shallow, inflorescence is in sequence, self-pollination is carried out, both main tip and side tip can bear seeds, the seeds are in circular sheet shape, and diameter is 1.5mm to 2 mm. The appearance color is white, cream yellow, purple red and black. Wherein the black and purple grains are smaller, and the white and creamy yellow tastes are better. Quinoa is a plant, but it has complete proteins that animals have, which is very rare. At present, people mainly eat chenopodium quinoa in a fresh mode or eat chenopodium quinoa in rice-flour cakes after being ground into chenopodium quinoa powder, but macromolecular proteins and functional polysaccharide ingredients in the chenopodium quinoa powder are difficult to digest and absorb by human bodies, so that the nutritional value of the chenopodium quinoa powder is greatly reduced. The quinoa or quinoa powder is directly used, the absorptivity of quinoa nutrient components is low, and quinoa resources cannot be fully utilized.

Calcium plays an important physiological role in all stages of the human body, especially in the period of children and teenagers, is an essential element for ensuring healthy growth and development, and children in the early growth and development stage have weaker digestion and absorption capacity for absorbing nutrient substances compared with adults.
