Embodiment 1

[0028] Concrete operation steps of the present invention are as follows:

[0029] (1) Take the waste dry yeast from the brewery and pass it through an 80-mesh sieve to remove impurities (you can also use other specifications of the sieve depending on the specific conditions of the dry yeast);

[0030] (2) Add 12g of calcium chloride to 50ml of distilled water and fully dissolve;

[0031] (3) Add the calcium solution into the dry yeast sieved in step (1) according to the ratio of 30ml calcium solution: 1000g dry yeast;

[0032] (4) Extrude the dry yeast added with calcium solution in step (3) with an extrusion blasting machine. The extrusion blasting machine can be SPJ-40 extrusion blasting machine, manufactured by Shaanxi Deai Food Co., Ltd. or Huanan Agriculture Developed by the Laboratory of Medium and Low Temperature Processing of Food at the University. The puffing condition is:

[0033] Expansion temperature: 130°C

[0034] Feed rate: 250g / min

[0035] Screw speed: 2...

Embodiment 2

[0040] Concrete operation steps of the present invention are as follows:

[0041] (1) Get beer waste yeast, cross 80 mesh sieves to remove impurities;

[0042] (2) Add 10g of calcium phosphate in 50ml of distilled water and fully dissolve;

[0043] (3) Add the calcium solution into the dry yeast sieved in step (1) according to the ratio of 50ml calcium solution: 1000g dry yeast;

[0044] (4) The dry yeast added with the calcium solution in step (3) is expanded with an extrusion blasting machine, and the expansion conditions are:

[0045] Expansion temperature: 125°C

[0046] Feed rate: 200g / min

[0047] Screw speed: 15Hz

[0048] Water supply: 20g / 100g dry yeast

[0049] (4) The expanded yeast is pulverized through an 80-mesh sieve;

[0050] The wall breaking rate of the dry yeast is 75%; the organic calcium content in the yeast organic calcium is 630 μg / g dry yeast.

Embodiment 3

[0052] Concrete operation steps of the present invention are as follows:

[0053] (1) Get beer waste yeast, cross 80 mesh sieves to remove impurities;

[0054] (2) Add 20g of calcium gluconate to 20ml of distilled water and fully dissolve;

[0055] (3) Add the calcium solution into the dry yeast sieved in step (1) according to the ratio of 20ml calcium solution: 1000g dry yeast;

[0056] (4) The dry yeast added with the calcium solution in step (3) is expanded with an extrusion blasting machine, and the expansion conditions are:

[0057] Expansion temperature: 140°C

[0058] Feed rate: 300g / min

[0059] Screw speed: 30Hz

[0060] Water supply: 80g / 100g dry yeast

[0061] (4) The expanded yeast is pulverized through an 80-mesh sieve;

[0062] The wall breaking rate of the dry yeast is 70%; the organic calcium content in the yeast is 580 μg / g dry yeast.

[0063] The yeast produced by the invention has a high content of organic calcium, which completely solves the technica...

Abstract

The invention discloses an organic chelate and a preparation method thereof. The organic calcium chelate is prepared by adding inorganic calcium salt and yeast content to generate the chelation reaction in the process of wall-breaking treatment of dry yeast. In the invention, the wall-breaking rate of the yeast is improved by utilizing dual functions of extrusion and temperature during the extruding and bulking through optimizing a wall-breaking method and chelation conditions, and the yeast content is dissolved out and generates the chelation effect with the inorganic calcium salt while hydrolyzing so as to produce the organic calcium chelate with low cost. The invention can adopts leftovers enriched in protein, such as industrial waste yeast, and the like as raw materials, has simple process, convenient operation, good continuity, large treatment capacity and easy implementation of the industrialization; and the obtained organic calcium chelate has stable and safe quality.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to an organic calcium chelate and a preparation method thereof. [0002] Background technique [0003] Calcium is the main component of bones and teeth. It plays an important role in the activation of certain enzymes in the blood coagulation, the maintenance of nerve conduction, the flexibility of muscles, the sinking osmotic pressure of capillaries, and the acid-base balance in the body. role. The use of calcium nutritional fortifiers is currently the most commonly used way of calcium supplementation. Nutrition experts believe that a good calcium nutrition enhancer should have the following characteristics: first, it requires high calcium content; second, it has a high absorption rate and bioavailability of calcium; sex. [0004] At present, there are three main types of calcium additives in the domestic market from the perspective of calcium source compositi...
