Anti-nutrients and heavy metals in some new plantain and banana cultivars
ثبت نشده
چکیده
Plantain and banana flour are important raw material in the baking and confectionery industry, and complementary food formulation. Five new plantain and banana hybrids developed by the International Institute of Tropical Agriculture (IITA) at Highrainfall Station, Onne, Nigeria were screened for certain anti-nutritional factors and some heavy metals commonly found in foods. Results show that PITA 17 is lowest (1.66%) in saponin, while PITA 24 (4.97%) is highest. Conversely, the tannin content was lowest (0.16%) in PITA 24 and highest (0.28%) in both PITA 17 and BITA 3. The oxalate content of the new hybrid ranges between 0.49% and 0.82%, across the six cultivars evaluated. Phytate level was lowest (1.2x10-5) in PITA 14 and highest (11.0x10-5) in PITA 24. PITA’s 14, 24 and Agbagba contained 4.0x10-5% cyanide, while 4.0x10-5 was obtained for PITA’s 17, 26 and BITA 3. The phenolic content of PITA’s 14 and 26, and Agbagba was 0.033%, while PITA’s 17, 24 and BITA 3 had 0.036%. The heavy metal contents of the new plantain and banana ranges between 0.13-0.19ppm for Lead, 0.02-0.03ppm for Cadmium, and <0.01ppm for Mercury, across the six cultivars investigated.

BACKGROUND The problems of vitamin A deficiency and chronic diseases have emerged in recent years in some countries in the Micronesian region. These problems are associated with the dietary shift towards imported processed foods and lifestyle changes. Research in the Federated States of Micronesia indicates that yellow- and orange-fleshed banana cultivars contain significant levels of provitami...
متن کاملThe effect of cadmium and mercuric chlorides on some physiological traits in two cultivars of wheat.
One of the important abiotic stresses that negatively affect cereals such as wheat is heavy metals. Soil pollution with heavy metals has become one of the major environmental concerns resulting from the industrial development and use of fertilizers containing heavy metals. One way to counteract the negative effects of heavy metals in plants which produce reactive oxygen species is the activatio...

Traditional starchy banana cultivation in the humid tropics is dominated by two widespread, but geographically discrete, groups of AAB cultivars: plantains in Africa and maoli-popo`ulu in the Pacific. Both AAB subgroups exhibit exceptionally high cultivar diversity due to multiple somatic mutations, and yet both subgroups have relatively similar genetic origins. Although both cultivar groups or...

There is minimal information about the effect of heavy metals such as lead and copper on pollen grains and pollen tubes of fruit trees. Fruit set of these plants are affected by different environmental, biological, physical and chemical factors. If one of these factors be abnormal, pollination, fertilization and fruit set and orchard yield will decrease. In polluted cities, this phenomenon is a...
