GDL inowanzowanikwa muuchi, muto wemichero, mafuta ekuzora, newaini[inoda]. GDL haina kwayakarerekera asi hydrolyzes mumvura kune gluconic asidhi ine acidic, ichiwedzera tangy kuravira kune chikafu, kunyangwe iine chikamu chetatu chekuvava kwecitric acid. Inogadziriswa kune glucose; giremu rimwe reGDL rinopa huwandu hwakafanana hwesimba remagetsi segiramu rimwe reshuga.
Pamusoro pemvura, GDL ine chikamu che hydrolyzed kune gluconic acid, ine chiyero pakati pefomu yelactone uye fomu yeasidhi inotangwa sekemikari yakaenzana. Chiyero che hydrolysis yeGDL inowedzerwa nekupisa uye yakakwirira pH
