Promasidor Ghana unveils new Onga Tomato Mix, names Diana Antwi Hamilton brand ambassador

Promasidor Ghana Limited recently introduced a new product, the Onga Tomato Mix, aiming to deepen the Onga brand's connection with Ghanaian consumers. The unveiling ceremony took place at the company's Cowbell Conference Room in Accra on August 18, 2026, with marketing manager Michael Hagen announcing the launch. This marks a significant milestone for the Onga brand, which has been present in Ghana for over two decades.

Hagen emphasized that the new product was developed with the local consumer in mind, aiming to stand out in a competitive market by prioritizing the Ghanaian consumer's needs. The company introduced Diana Antwi Hamilton as the brand ambassador for the Onga Tomato Mix. Antwi Hamilton, a renowned award-winning gospel musician, was chosen due to her career achievements and alignment with the brand's values.

Hagen explained that Antwi Hamilton embodies the qualities Promasidor seeks to associate with the brand, being a successful professional and musician. Antwi Hamilton expressed her excitement about the role, viewing it as a partnership founded on mutual values of quality, excellence, and service. She also shared that her own relationship with Onga predates the ambassadorship, as she has been a long-time consumer of the product.

Antwi Hamilton is eager to leverage her platform to introduce more consumers to the Onga Tomato Mix, reinforcing confidence in the brand through her endorsement.
