Problems solved by technology

However, the flash point of zinc glycinate is below 100°C, which is lower than the cooking temperature in most cases. Moreover, acidic seasonings such as vinegar are often added in the cooking process, which may react with the amino group in zinc glycinate and affect the effective absorption of zinc glycinate.

Embodiment 1

[0030] A method of preparing zinc-rich refined salt, the specific steps are as follows:

[0031] (1) 1 kg of cassava starch is first added to 28 kg of water, stir mix, stir it to 65 ° C, add 2.5 kg of mass concentration of 30% hydrogen peroxide solution, heating degradation reaction, to obtain partially degraded tapas starch;

[0032] (2) The 10kg portion is then removed from the tapioca starch, and the 2kg mass concentration of 30% sodium hydroxide solution and 2 kg of mass concentration of 45% chloride solution were slowly added dropwise, and the mixture was stirred. Then, 5 kg of glycine is added, mix well, high pressure homogeneous, spray dry, and obtain pretreatment starch;

[0033] (3) The pretreatment starch is then extruded, and the starch microsphere is obtained, and finally the 0.3 kg of starch microspheres are added to 100 kg of refined salts, and mix well, that is, the zinc-rich refined salt is obtained.

[0034] Among them, in step (1), the process conditions for heat...

Embodiment 2

[0041] A method of preparing zinc-rich refined salt, the specific steps are as follows:

[0042] (1) First, 10 kg of cassava starch is first added to 32 kg of water, stir mix, stir it to 60 ° C, add 3.5 kg of mass concentration of 25% hydrogen peroxide solution, heating degradation reaction, to obtain partially degraded tapkoca starch;

[0043] (2) The 10kg portion is then removed from the tapioca starch, and the 3kg mass concentration of 25% sodium hydroxide solution and 3 kg of mass concentration of 40% zinc hydroxide solution are simultaneously added to the mixed mixture, and the mixture is stirred. Next, 6 kg of zinc glycine, stir mix, high pressure homogeneous, spray dry, to obtain pretreatment starch;

[0044](3) by extrusion and then pretreated starch to give starch microspheres, and finally taken 0.3kg starch microspheres are added salt in 100kg purified, mixing with stirring, to obtain a zinc-rich purifying said salt.

[0045] Wherein step (1), the reaction conditions for...

Embodiment 3

[0052] A method for preparing purified salts of zinc, the following steps:

[0053] (1) First tapioca starch 10kg 30kg of water was added, stirring and blending the mixture was stirred and heated to 63 ℃, 28% over the concentration of hydrogen peroxide solution 3kg heated degradation reaction, to give partially degraded tapioca starch;

[0054] (2) is then taken partially degraded tapioca starch 10kg, 2.5kg was slowly added dropwise thereto while a concentration of 28 mass% sodium hydroxide solution and 2.5kg mass concentration of 42% zinc chloride solution, stirred for complexing, partially complexed starch slurry, followed by addition of zinc glycinate 5.5kg, stirred mix, high pressure homogenization, spray drying, to give pretreated starch;

[0055] (3) by extrusion and then pretreated starch to give starch microspheres, starch microspheres were finally taken 0.35kg 100kg purified salt was added, the mix was stirred, to obtain a zinc-rich purifying said salt.

[0056] Wherein s...

Abstract

The invention discloses a preparation method of zinc-rich refined salt, the preparation method comprises the following steps: adding cassava starch into water, uniformly stirring and mixing, adding a hydrogen peroxide solution, and heating for degradation reaction to obtain partially degraded cassava starch slurry; then slowly dropwise adding a sodium hydroxide solution and a zinc chloride solution into the partially degraded cassava starch slurry at the same time, stirring and complexing to obtain partially complexed starch slurry, then adding zinc glycinate, stirring and mixing uniformly, homogenizing at high pressure, and spray-drying to obtain pretreated starch; carrying out extrusion puffing treatment on the pretreated starch to obtain starch microspheres, finally adding the starch microspheres into refined salt, and uniformly stirring and mixing to obtain the product. The refined salt is rich in organic zinc components, high in bioavailability, capable of achieving the zinc supplementing effect, good in caking resistance and good in market popularization prospect.

Description

Technical field [0001] The present invention relates to a method of preparing a zinc-rich refined salt. It belongs to the field of salt processing technology. Background technique [0002] The consumption refined salt is a raw material made from a brine or sea salt such as a sea salt or a sea salt, a lake salt, and a chemical method. After clarifying, evaporation, crystallization, and dehydration after chemical methods. , Dry and sieve. The sea salt field, the lake salt field is based on the original salt salt, and the consumption salt is produced by more efficient vacuum evaporation. The well moiral salt area is a raw material for a brine or underground natural brine obtained by a rock brine, and produces a refined salt. [0003] Zinc is one of the trace elements necessary for the human body. It plays an extremely important role in human growth, reproductive genetics, immunity, endocrine. Zinc is the composition ingredient of the enzyme protein, which can promote the immune func...
