| Innovation Title | Nutritional and Antinutritional Information and Labels for Root, Tuber and Banana based products in Zambia |
| Innovation description | Detailed information on the nutritional and antinutritional factors for the RTB-based products developed. β-amylase (Amyβ) is a thermostable enzyme that hydrolyses starch during cooking of sweetpotato (Ipomoea batatas) storage roots, thereby influencing eating quality. The genetic diversity of the gene was studied, and a mutation associated with low enzyme activity in sweetpotato roots was identified. |

Stage reached
| Stage of Innovation | Stage 3: available/ ready for uptake |
| Year (Stage) | 2021 |
| Stage Description | The samples’ anti-nutritional components were within the recommended safe World Health Organization limits. Implementing the food safety standards for high quality cassava flour (HQCF) in Zambia and training of processors on HQCF production is recommended. The sweetpotato breads highlight usefulness as novel functional foods to address vitamin A deficiency. |
