The invention discloses an easily absorbable organic
calcium powder containing mineral elements and a preparation process thereof, and the raw materials comprise, by weight, 50-70 parts of an organic
calcium source, 20-30 parts of a
plant protein source, 5-10 parts of a polybasic
amino acid chelate, 0.01-0.03 part of
vitamin D3, 1-3 parts of
trace mineral elements, 0.5-1.5 parts of compound
protease, 0.1-0.3 part of a food-grade surfactant, and 100-150 parts of deionized water. The invention relates to the technical field of nutritional supplements. According to the mineral element-containing easy-to-absorb organic
calcium powder and the preparation process, vegetable
protein is converted into
amino acid through biological enzymolysis, the
amino acid and
calcium carbonate are subjected to a
chelation reaction to generate amino acid
chelated calcium, and compared with traditional organic calcium,
chelated calcium is more easily absorbed by human intestinal tracts; meanwhile, calcium,
magnesium and
phosphorus are synergistically matched,
magnesium can activate
vitamin D3, the
vitamin D3 further promotes absorption of calcium,
phosphorus and calcium form a reasonable proportion, deposition of calcium in bones is enhanced, and calcium ions can be absorbed in intestinal tracts without depending on
gastric acid by adopting a bicyclic stable chelating structure.
