Secondly, purple sand has dense texture, fine pores, and is breathable but impermeable. Therefore, cooked food can not only effectively retain its original nutrition and flavor, but also is not easy to deteriorate even if it stays overnight in summer.
Third, the natural iron contained in purple sand can dissolve fat, so the cooked rice is particularly fragrant and delicious, while the broth is less oily, which is suitable for dieters. Scientific experiments have proved that pure water will be mineralized into weak alkalinity with a PH value of about 7. 1 after boiling in a purple clay pot, which is beneficial to the formation of weak alkalinity health.
