On a Kangen your able to select the level of alkalinity you want for your water, level 4 on the Kangen is specifically designed for boiling water to be used in cooking, soups, rice and stews, level 4 will help reduce acidity in these foods, when you boil alkaline water it retains its alkalinity but it is claimed the number of positive ions are reduced because of oxidation whilst the micro clusters of water molecules which it is claimed by alkaline water enthusiasts are inherent to alkaline water will remain.
Boiling ionised alkaline water does reduce its health benefits but itís claimed itís still better than tap water or another source of un-ionised water, however you can safely freeze ionised alkaline water and still enjoy all itís health benefits of thawing.
You can boil alkaline water to make tea, coffee, soups, rice or noodles, drinking alkaline water itís claimed can help slow the ageing process and regulate your bodies pH (acidity levels), so why not change all your water drinking including hot water over to alkaline water.
For cooking the water produced by your ioniser will be more alkaline than for normal drinking water as some of the alkalinity is lost by boiling so you must start with a higher level of alkaline pH which will reduce after boiling, normal alkaline drinking water might be 8 or 9 ion the pH scale.
You donít need anything fancy to boil Kangen water, you can use a kettle, if you have limescale then descale your kettle first to prevent adding impurities to the Kangen water.
You can also microwave alkaline water, microwaving water just causes the water molecules to vibrate rapidly and heat up, thatís how microwaves work, alkalinity will be lost equally by boiling on the hob in a pan or by boiling in a kettle or using a microwave.
You should wash your vegetables before boiling in water by washing in a strong acidic Kangen water to clean the vegetables.
