Antioxidant activity and calcium bioaccessibility of Moringa oleifera leaf hydrolysate, as a potential calcium supplement in food

다국어 초록 (Multilingual Abstract)

Moringa oleifera leaf (ML) is rich in vitaminsand minerals, specially abundant calcium, therefore it iswidely used as a calcium supplement for food. This studyaimed to investigate the antioxidant activity and calciumbioaccessibility of M. oleifera leaf hydrolysate (MLH) as acalcium supplement for kimchi. MLH was prepared underthree different proteases, two different protease contents,and three different incubation times. Total phenol content(TPC), total flavonoid content (TFC), and antioxidantactivities were investigated. Cellular activity and calciumbioaccessibility were also investigated. The highest calciumlevel of MLH was observed in 3% Protamex treatmentfor 4 h. TPC, TFC, and antioxidant activities of MLHin Protamex and Alcalase treatments were higher thanthose in Flavourzyme treatment (p\0.05). Moreover,high cell viability and alkaline phosphatase activity werealso observed in C2C12 cells. Kimchi containing MLHshowed high calcium accessibility compared to kimchialone. Taken together, the application of MLH could havepotential as a calcium supplement for kimchi production.
