Orange juice fortified with calcium citrate malate (CCM) has been extensively studied and is therefore well known and well regarded as being highly absorbable calcium. PURAC has launched a calcium lactate citrate comparable in absorbability to CCM calcium with the added benefits of also being taste and flavor enhancing and easy to use: PURACAL QSynergy. 

A clinical study in orange juice was conducted in 2007 at the Osteoporosis Research Centre of Creighton Unversity, Omaha, Nebraska, with a group of pre- and post-menopausal women.  Two calcium fortification systems added to unfortified orange juice were compared to commercial orange juice with CCM calcium.  The two comparison calcium systems were 1) PURACAL QSynergy calcium lactate citrate and 2) a mixture of tricalcium phosphate and PURACAL PP calcium lactate (each of the two salts providing 50% of the total calcium).  The study established that PURACAL QSynergy when incorporated into orange juice exhibits absorbability indistinguishable from that of CCM. Similarly, the alternative fortification system (50% calcium from PURACAL PP calcium lactate with 50% calcium from tricalcium phosphate), while exhibiting a slightly lower mean absorbability value, nevertheless results in very nearly as much absorption as the other two calcium fortificants. For production ease, PURACAL QSynergy is significantly more soluble than calcium citrate and calcium phosphate and is the sole calcium source necessary.  PURACAL QSynergy will stay homogeneously suspended throughout production and will not scale on heat-exchangers.  Consumers will appreciate that PURACAL QSynergy enhances the fresh fruity flavor of juices without chalkiness or flavor-dulling commonly associated with calcium fortification.
