“…This fact occurs due to the mixture of different antioxidant compounds and the reaction rate for each one. Martínez et al (2017) quantified the presence of vitamin C in the extract and reported that its antioxidant efficiency was higher than the other compounds. This fact indicates that the initial decay is caused mainly by the reactivity of vitamin C.…”

“…oleifera is considered a significant source of β-carotene, vitamin A, B, and C, minerals, and phytochemicals that exhibit a demonstrated antioxidant activity. In addition, M. oleifera extracts exhibit significant pharmacological activities against inflammation, diabetes and hyperglycaemia, cancer, and neurodegeneration diseases, amongst others (Martínez et al, 2017;Nobossé et al, 2018;Xiao et al, 2020).…”

In this study, an antioxidant-rich extract was obtained by leaching Moringa oleifera leaves. The activity of the extract against the 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical was measured by determining a second-order rate constant (k2). The reaction between the mixture of antioxidants in the extract and the DPPH was monitored by measuring the absorbance at 517 nm in 30-second intervals for a period of 600 s. The absorbance exhibited a rapid decay within the first 100 s, followed by a slower decay. The absorbance data were fitted to a bi-exponential model. The curve fitting showed a linear relationship between the initial concentration of antioxidants and the reaction rate with the coefficient of determination values greater than 0.9979. The k2 value was 0.0870 ± 0.0007 mg/mL.

Moringa (Moringa oleifera) is rich in minerals, vitamins, and other essential phytochemicals. This research aimed to evaluate the effect of addition skim milk powder to the characteristics of probiotic drinks based on moringa leaves juices. The probiotic drink was fermented by Lactobacillus casei FNCC 00090 with different levels of skim milk powder (0, 3, 5, and 7%). The results showed that supplementation skims milk powders significantly affected the color of the probiotic product. The higher level of skim milk powders, the lighter, greener, and more yellow in the color (P<0.05). The higher concentration of skim milk, the higher of pH and lactic acid content resulted. The number of probiotics among the treatment was not significantly different. The addition of 7% skims milk powder produced the highest protein content, anti-bacterial activity, phenolic content, and antioxidant activity. This product has a protein content of 2.65%, antibacterial activity: 14.50±1.80 mm (zone inhibition of E. coli) and 35.33±4.16 mm (zone inhibition of S. aureus), phenolic content of 0.2410±0.0054 mg equivalent gallic acid/mL sample, and antioxidant activity of 75.18±1.45%. The probiotics drink based on moringa leaves juices has the potential to be developed as a functional drink.
