Problems solved by technology

Among them, the first type of calcium preparations often have the disadvantages of being difficult to absorb and having low calcium content. What is more fatal is that some products may easily lead to excessive heavy metal content due to defects in the manufacturing process.
The second-generation calcium preparations often have the defects of low calcium content and low utilization rate

Embodiment 1

[0027] (1) Soak 130 g of oyster shells in 0.5% hydrochloric acid solution for 1 hour, then scrub to remove adsorbates such as silt on the surface of the shells, dry at 100°C for 1 hour, and crush through a 100-mesh sieve to obtain 110 g of oyster shell powder. Weigh again 100g of the screened sample, add it to 175ml of 3mol / L hydrochloric acid, mix, act at a temperature of 110°C for 2 hours, filter, concentrate under reduced pressure, and spray dry to obtain 70g of denatured soluble calcium containing 28.08%. Oyster shell powder.

[0028] (2) Take 218g of oyster meat, wash it, cook it at high temperature, grind it into a slurry, add 1L of water to make an aqueous solution with a protein mass fraction of 2%, put it in a reactor, soak it in a water bath at 55°C for 30 minutes, and mix it according to the amount of enzyme and substrate protein. Add 11g of neutral protease at a ratio of 8000U / g, adjust the pH of the solution to 7.0 with phosphate buffer; put it in a constant tempe...

Embodiment 2

[0031] The present invention selects the first-generation calcium product calcium carbonate, the second-generation calcium product calcium lactate, and the calcium product compound amino acid chelated calcium of the present invention as calcium supplements, and the following comparative experiments have been carried out on animals:

[0032] Experiment 1: Effects of compound amino acid calcium on mouse coat, skin and internal organs.

[0033] Step 1: Select 40 healthy mice and randomly divide them into 4 groups, with 10 males and more than half males in each group. In addition to the same conventional feed, the three groups were fed with different calcium supplements for comparative experiments, and one group was only fed with feed for blank comparative experiments. The method of calcium supplement measurement is: different calcium supplements are converted into calcium element, that is, the mass of calcium element supplied per kilogram of animal weight per day (mg.kg -1 .d -...

Abstract

The present invention discloses a composite amino acid chelated calcium prepared by using oysters as raw materials which consists of the composite amino acid powder prepared by oysters and the modified calcium carbonate prepared by oyster shells; the soluble calcium content of the modified calcium carbonate is 28.08%, the mass ratio of the composite amino acid powder prepared by oysters and the modified calcium carbonate prepared by oyster shells is 1:1.5; the composite amino acid chelated calcium not only improves the absorption and utilization of medicines, but also opens up a new way for the comprehensive utilization of the oyster shells, and thereby greatly improving the added value of freshwater aquaculture.

Description

technical field [0001] The invention relates to a compound amino acid chelated calcium, in particular to a compound amino acid chelated calcium prepared from oysters. Background technique [0002] my country has many lakes, vast sea area, and rich shellfish resources, such as oysters, mussels, clams, and snails. Oyster meat is rich in amino acids and rich in nutrition. As a food material, it is a seafood that people like to eat. In recent years, its nutritional value has been fully recognized by people. It is also because of its low growth environment requirements, rapid growth, and less intrusion of diseases and insect pests. , so it is widely cultivated, and the amount of harvest increases year by year, and its added value can be increased through its deep processing. With the progress of modern science and technology, various oyster health care products have been developed in the world, and oyster shells are often thrown away as waste, which has become an environmental p...
