It is important to identify the concentration at which maltodextrin can perform the best healing capability [33]. Therefore, different concentrations of RB maltodextrin (5%, 10%, and 20%) with the same DE value of 10–14 were conducted (Table 1(b)). Addition of 100 ppm additives to each maltodextrin was studied also in the wound healing process of NIH 3T3 cells. The response obtained from each NIH 3T3 cells after exposure to different concentrations of maltodextrin was distinguishable (p < 0.01) than responses received in the control group. In Table 1(b), treatments with either 5% or 20% RB maltodextrin were not able to heal the wounds completely within 24 h. These two concentrations did not show significant improvement (p < 0.01) in the percentage of wound closure relative to the control group. The addition of 5% RB maltodextrin into NIH 3T3 wounded cell was found to be too liquefied and could not provide sufficient nutrients to the cells leading to poor cell migration. On the other hand, high concentration of RB maltodextrin (20%) was not suitable to be used in wound healing as it was too concentrated and yield a syrup-like characteristic due to high solid content [9]. These results indicated that high viscosity of RB maltodextrin prevents the absorbance of nutrients to the cells to enhance the proliferation and migration of the cells. Only 10% concentration of RB maltodextrin was capable of achieving 100% recovery within 24 h as shown in Tables Tables1(b)(ii)1(b)(ii) and and2.2. It was also noted that 10% RB maltodextrin alone showed the best wound healing of NIH 3T3 at 12 h (61.13%), followed by 10% RB maltodextrin with 100 ppm curcumin (52.97%), 10% RB maltodextrin with 100 ppm hydroxyproline (51.52%), 10% RB maltodextrin with 100 ppm ascorbic acid (47.78%), 10% RB maltodextrin with 100 ppm L-arginine (47.66%), 10% RB maltodextrin with 100 ppm lactic acid (44.94%), and 10% RB maltodextrin with 100 ppm kojic acid (32.98%). Multidex was found to cause a cytotoxicity rather than wound healing effect on the NIH 3T3, whereby the cells were observed to be unhealthy and unable to migrate and died within 12 h as shown in Table 2. This may be contributed by the presence of preservative in the Multidex [6] since Multidex is formulated for external use only and may not be a suitable agent for in vitro wound healing study.
