Problems solved by technology

[0004] 1. Because its content can only reach about 99%, it cannot meet the requirement of edible potassium chloride export purity (content) ≥ 99.5%, and it must pay an export tariff of 600 yuan per ton of products before exporting, which limits the export of products.
[0005] 2. Because of problems such as easy moisture return, agglomeration, and poor fluidity, it cannot meet the quality requirements of low-sodium salt production for edible potassium chloride
[0006] 3. Failure to take effective measures to remove the octadecylamine organic matter in the product is not conducive to human health
[0009] The existing production process of edible potassium chloride cannot remove the above-mentioned substances in the raw material potassium chloride to the greatest extent
As a result, edible potassium chloride products have low content, easy caking, poor taste, poor fluidity, and peculiar smell, which cannot meet the quality requirements of the low-sodium salt industry and export potassium chloride

Abstract

The invention provides a preparation method of high-quality edible potassium chloride and relates to the field of food additives. By adding potassium carbonate, potassium hydroxide, adsorbent and other substances into an industrial or agricultural potassium chloride aqueous solution, not only can calcium, magnesium and ammonium in potassium chloride be effectively removed when edible potassium chloride is prepared, but also octadecylamine organic matter and heavy metals can be effectively removed, and the quality of edible potassium chloride is greatly improved.

Description

technical field [0001] The invention relates to the field of food additives, in particular to a preparation method of high-quality edible potassium chloride. Background technique [0002] Potassium chloride is white crystalline powder or colorless crystal, easily soluble in water, and can be used as salty agent and nutritional supplement. In order to prevent people from taking too much salt, it can be used as a substitute for some salt, and like salt, it can be used as a flavoring agent for various foods such as agricultural products, aquatic products, livestock products, fermentation, seasoning, canned food, and convenience foods. It is one of the main raw materials for the manufacture of low-sodium edible salt. [0003] Though the edible potassium chloride of domestic production can reach the requirement of each physicochemical index of national standard (GB25585-2010) from physical and chemical index at present, there are generally following problems: [0004] 1. Becaus...
