Zusammenfassung:	PURPOSE:To prepare dried onion having improved restoring properties and long- term shelf stability free from adhesion of thin pieces one another, by drying thinly cut onion with hot air, boiling it in water, washing it with water, dehydrating it, followed by drying. CONSTITUTION:Onion which is thinly cut into 3-4mm. thickness and 20-30mm. length is dried with hot air at 60-120 deg.C until its water content is 6-10wt%. It is immersed in 5-15 times as much water as it by weight, boiled at 90-150 deg.C for 1-5hr, cooled quickly with water in an amount to give >=0.5 as much as the total amount of the boiled mixture, and washed with water. The onion is dehydrated by a centrifugal separator to 88-92wt% water content, frozen quickly, and lyophilized or subjected to vacuum drying.
