The results showed that the anthocyanins from flowers of R. pulchrum were relatively stable in the room with natural light,at temperature lower than 45℃,and in the solution with p H ≤ 4. The addition of Na^+,K^+Ca^(2 +)metal ions,glucose,sodium benzoate,acetic acid and salt had little effect,but Cu^(2 +),Zn^(2 +),Fe^(3 +),Al^(3 +),starch and sodium glutamate showed adverse effects on the stability of the anthocyanins. The anthocyanins from flowers of R. pulchrum had a good antioxidant effect,and their scavenging capacity for · OH,O^(2-)·,DPPH· was better than that of the same concentration of Vc.展开更多

Two formulations of sweets based on jujube, baobab fruit powder and sweet potato puree were produced, and their nutritional values and sensory properties such as taste, smell, color and acceptability were assessed. The formulation containing the most jujube powder, baobab fruit and sweet potato puree gave the best nutritional value. The sweets are rich in calcium (259.80 mg/100 g), magnesium (67.98 mg/100 g), potassium (782.04 mg/100 g), vitamin C (32.37 mg/100 g), iron (6.45 g mg/100 g) and zinc (0.97 mg/100 g). Sensory tests on the two formulations showed acceptability scores ranging from 81.26% to 84.58%, well above the minimum acceptable threshold. Candies with jujube, baobab fruit powder and sweet potato puree could be an alternative for preventing micronutrient deficiencies.展开更多

However, some constraints related to climate change limit its production. This study evaluated the agronomic and technological performances of eight varieties of orange-fleshed of sweet potato (Ipomoea batatas (L.) to identify the most promising ones. The results show three groups of varieties with different agronomic performances. Group 1 composed of Irene and Vita is characterized by low production of small and large tuberous roots, low number of productive plants and low yield. Group 2 consisting mainly of Kabode is characterized by high production and weight of large tuberous roots as well as high yield. Group 3, composed of Tacha-2 Ininda, Ejumula Gloria, TIB-440060, CIP-199062-1, Bela bela is characterized by high production of small and large tuberous roots, high number of productive plants and average yield. The TIB-440060 variety has a recovery rate of 100%. The Irene, Kabode, Vita, Kabode varieties were resistant to viral and fungal diseases. In terms of technological quality, the TIB-440060 and CIP-199062-1 varieties have the best organoleptic qualities. Given the agronomic performances of the Kabode, TIB-440060 and CIP-199062-1 varieties, could be selected as the elites varieties and distributed to producers.展开更多
