Healthy common salt and production process thereof

Abstract

The invention provides a healthy common salt which is prepared by crude salt, calcium carbonate, magnesium carbonate, propylene glycol, potassium iodate, ferric citrate, ferric ammonium citrate, sodium selenite and zinc sulfate according to weight ratio; the invention further provides a production process of the healthy common salt: dissolving the propylene glycol, the ferric citrate and the ferric ammonium citrate in water, and dissolving the potassium iodate, the sodium selenite and the zinc sulfate in another water; respectively continuously spraying the two types of solution on the crude salt distributed on a conveyor belt through a nozzle; continuously feeding the crude salt into a boiling drying bed, drying at the temperature of 75-85 DEG C, leading the water to be not more than 0.2%, and feeding into the conveyor belt; mixing the calcium carbonate with the magnesium carbonate, and adding on the crude salt which is distributed on the conveyor belt and fed onto the conveyor belt after drying through a quantitative feeder; feeding the crude salt with auxiliary materials into a rotary mixer, and fully mixing; and packaging, and warehousing after passing the detection. The healthy common salt has good loose effect, convenient storage and transportation, difficult deliquescence and consolidation and high nutritional value, thereby being consistent with the declaration of national green food certification and meeting the requirements on foreign foods and domestic green foods.

Description

technical field [0001] The invention belongs to the technical field of edible salt, relates to an edible salt and a production process thereof, in particular to a healthy edible salt and a production process thereof. Background technique [0002] With the continuous improvement of people's living standards, people have higher requirements for the safety and nutrition of the food they eat; sodium chloride is the most widely used food flavoring agent and nutrition agent, and its safety and health are more important. focus on. [0003] At present, there are not many varieties of edible salt in my country, but the demand is relatively large, about 7 million tons per year, and most of them only add nutrient elements such as potassium iodate (20-50mg / kg) stipulated by the state, which is not conducive to people's consumption of salt. Balanced intake of nutrient elements; in addition, in order to prevent caking in domestic edible salt, ferrocyanide (potassium ferrocyanide, sodium f...

Problems solved by technology

[0003] At present, there are not many varieties of edible salt in my country, but the demand is relatively large, about 7 million tons per year, and most of them only add nutrient elements such as potassium iodate (20-50mg / kg) stipulated by the state, which is not conducive to people's consumption of salt. Balanced intake of nutrient elements; in addition, in order to prevent caking in domestic edible salt, ferrocyanide (potassium ferrocyanide, sodium ferrocyanide, added amount 3-10mg / kg) is added as an anti-caking agent for edible salt , because: the safety of potassium ferrocyanide as a food additive has not been recognized by countries such as Europe, America, and Japan; my country's green food clearly stipulates that no ferrocyanogen group should be contained, and the existence of potassium ferrocyanide affects edible salt or added Food with this product declares green food certification

The existing edible salt can no longer meet the requirements of foreign food and domestic green food
