Generally, after sealing the edible water, place it in a cool place as soon as possible. The shelf life is about 2 years. It is recommended that you buy according to your usage. If it is a store, buying 20 pieces at a time is enough. If only potassium carbonate and sodium carbonate are used to prepare the liquid, the properties will be very unstable and will easily deteriorate during long-term storage. Generally, 10% phosphate or polymeric phosphate is added to improve water retention, viscoelasticity, acid-base buffering properties and metal sealing ability.

Jian Shui:

Jian water, also known as alkaline water, or edible Jian water, is a compound food additive and a material in food technology. Common traditional ingredients for pastry. The water used now is no longer plant ash, but an alkaline mixture prepared based on the composition and principles of plant ash, using potassium carbonate and sodium carbonate as the main components, supplemented by carbonates or polymeric phosphates. The function is the same as that of plant ash Lishui, so it is still called Lishui.
