Competing under the aegis of a new promoter in Hope and Glory Boxing, in association with the World Boxing Council (WBC), the 35-year-old Akhil got the better of Momba in the very first round of what was to be a six-round super lightweight (63.5kg) contest.
The former Commonwealth Games gold-medallist left his rival with a bloodied face, forcing an early end to the proceedings.
"He was bending too much and perhaps that is why he got hit so badly by the uppercut. It got over too early but a win is a win, I will take it," Akhil told PTI after his bout.
He got the better of Georgian Dato Nanava. Jitender was also competing in just his second professional bout and maintained his unbeaten record.
In the WBC title fight, India's Brijesh Kumar Meena notched up a over Dennis Padua of Philippines, defeating him in the eighth round.
