Abstract
The phytochemical and antioxidant properties
of date sweetened simulated milk powder (plant-based dairy source) from awara
(soy curd) was studied. A total of five sample with ratio 100%, 75:25, 70:30,
65:35 and 60:40% for awara and date were generated and used for the formulation
of the simulated milk based on mixture design. The simulated milk samples were
subjected to phytochemical and antioxidant evaluation using standard
procedures. The result reviewed the presence of total phenolic, total
flavonoids, tannins, saponins and glycosides in both the sweetened and
unsweetened simulated milk and values significantly p<0.05 ranged from
0.58-0.59mgGAE/100g, 0.90-2.07mgGAE/100g, 8.83-9.32, 1.42-3.32 and
2.64-4.05mg/100g, respectively except for total phenolic content. The DPPH
radical scavenging activity assay for the sweetened and unsweetened simulated
milk powder reviewed %inhibition values of 56.45-88.94, 65.31-91.20,
75.24-91.98, 80.96-92.17, 81.35-92.66% at 50, 100, 150, 200 and 250ug/ml,
respectively with IC50 values of 90.50 (75:25), 91.67 (65:35), 93.67 (60:40),
107.50(70:30) and 112.67ug/ml (100% unsweetened simulated milk). All simulated
milk powder with DPPH IC50 values below 100ug/ml means moderate antioxidant
activity. The total antioxidant capacity assay of the sweetened and unsweetened
simulated milk ranged from 63.50-89.40, 63.50-89.70, 64.83-89.74, 68.23-89.85,
70.33-93.32% for 50, 100, 150, 200 and 250ug/ml concertation with IC50 range
from 104.50-185.50ug/ml (sweetened) indicating weak antioxidant capacity and
250.50ug/ml (unsweetened) indicating inactive antioxidant capacity. This
inactive antioxidant capacity of the unsweetened simulated milk showed that the
addition of date palm did not only enhance the taste but also its total
antioxidant capacity. Thus, an addition to the healthy plant-based dairy powder
and scalable opportunity for both small- and large-scale industry as soy bean
is locally sourced.
