Scallop Shell Calcined Shell Calcium （Calcium Hydroxide）

Ingredient Summary

Food Additive from 100% Natural Material

There is a lot of demand for scallops for export, and a lot of them are farmed in Hokkaido and Aomori prefectures, but the large quantities of shells produced are an issue for the production areas as they are considered industrial waste.
Although it is also used as fertilizer, most of the shells remain unused.
Calcium oxide (CaO) is a strongly alkaline food improver that is made from the unused shells and heated at a high temperature of approximately 1,000℃ to produce calcined calcium,which is then powdered under sterile and anhydrous conditions.
Calcium hydroxide (Ca(OH)2) is made by reacting calcium oxide with water and turning it into powder.
When both calcium oxide and calcium hydroxide are dissolved in water, they form a calcium hydroxide aqueous solution and show strong alkalinity.
Utilizing this characteristic, it is used in vegetable cleaning agents, virus disinfectants, etc. The aqueous solution is strongly alkaline, so be careful not to get it in your eyes while handling.
