“…The phenolic content of blanched leaves and sapped content were 17.17±0.58 and 15.17±0.29 GAE/100 g, respectively. Similar data were reported by Adeniji et al (2007) when they worked on heavy metals and antinutrients in banana and plantain cultivars. Saponin increased from 225.00± 0.00 mg/100 g in freshly harvested and blanched leaves to 243.33±2.89 mg/100 g in boiled leaves.…”

Nutritional composition, phytochemical and anti-nutrient properties in blanched, boiled, leaves extract, and its residues respectively of Cnidoscolus aconitifolius, were determined using standard analytical methods. The moisture content significantly differed, with its values ranging from 89.30±0.21% in fresh leaves to 68.10±0.02% in leaf residue; the leave extract had the highest protein content (3.76±0.06%). There was no significant difference in the fat content of the blanched and boiled leave samples (0.30±0.00%), and the ash content significantly decreased. Leaves residue after extraction had the highest energy value (89.79), carbohydrate content (22.96±0.03%), and fibre content (4.07±0.05%). Alkaloids and flavonoids content significantly (p˂0.05) decreased from 108.33 and 260.00 mg/100 g, respectively in freshly harvested leaves to 83.33 in boiled leaves and 183.33 mg/100 g in the leaves extract, respectively. Carotenoids and oxalate significantly decreased from 1906.67 μg/100 g and 78.33 mg/100 g in freshly harvested leaves to 1840.00 μg/100 g and 31.67 mg/100 g in blanched leaves and leaves residue after extraction, respectively. Boiling increased the saponin content to 243.33 mg/100 g from 225.00 mg/100 g in fresh leaves. Phytate and tannin decreased significantly (p˂0.05) from 50.00 and 66.67 mg/100 g, in fresh leaves to 15.33 and 19.33 mg/100 g in boiled leaves, respectively. It would be a rich source of nutrients and phytochemicals, if it is well processed to reduce its anti-nutritional content.

“…Similarly, the anti-nutrient levels of M. subhyalinus are lower than those reported for some animal and plant food products. For instance, Akinyede et al (2005) reported phytic acid and tannin contents of full fat Dioclea reflexa to be 0.34 and 0.20% (mg/kg), Tannin and oxalate contents of plantain were 0.28% and 0.82%, respectively (Adeniji et al, 2007), compared to relatively lower tannin (4.7×10 -8 -5.5×10 8 % mgTA/100g) obtained for M. subhyalinus in this study. Tannins have been reported to interfere with digestion by displaying anti-trypsin, anti-proline and anti-amylase activity in higher animal (Helsper et al, 1993;Omotosho and Adedire, 2008).…”

Termite is used in many parts of the world but little is known about their biochemical properties and nutritional value as food. Protein digestibility and anti-nutrients of four castes (queen, worker, soldier and winged (alate)) of subterranean termite, Macrotermes subhyalinus were determined to evaluate the protein bioavailability and confirm nutritional value as food for human and animal consumption. Physico-chemical properties of the oil of each caste were also determined to reveal the potential uses of the oil and its stability in storage using standard analytical methods. The queen was the most easily digestible (84.72%) of the castes while the soldier was the least with a digestibility value 81.10%. The queen was significantly more digestible than the other castes. In general, all the four castes have low anti-nutrient (oxalate, phytate and tannin) values. Among the castes, worker has significantly higher anti-nutrient levels than the other castes. In general, worker and soldier have relatively higher digestibility values and significantly higher anti-nutrient contents as well as relatively higher values for most of the physico-chemical parameters tested, suggesting that they are the least edible caste. Overall, the results showed that all four castes of M. subhyalinus have very low levels of anti-nutrients tested for, are easily digested and produce edible oil. These findings confirm that all four castes of M. subhyalinus, and possibly other termite species, are safe for human and animal consumption, and therefore recommended for inclusion in human foods and livestock feeds

“…The heavy metal contents of plantain and banana hybrid peels are in consonance with the 0.01 mg•kg -1 to 0.006 mg•kg -1 lead, cadmium, mercury and chromium levels reported in some seafoods [55] in Rivers State waters in Nigeria. However, these new data are higher than those reported in plantain and banana flour [26]. Lead concentrations ranging from 1.…”

“…This study revealed that plantain and banana peels had higher levels of antinutrients than those reported by Adeniji et al [26] for the antinutrients and heavy metals in plantain and banana flour of pulp. Even though anti-nutritional properties have been ascribed to saponins, they are harmless when ingested by chicks, rats and mice at 0.5% to 3% of the diet because neither saponins nor sapogenins were found in the blood of chicks, rats and mice kept on a diet containing 20% soybean meal [27].…”

Antinutrients and heavy metals in new Nigerian Musa hybrid peels with emphasis on utilization in livestock production. Abstract-Introduction. A comparative study of antinutrients and heavy metals in the peels of five improved varieties of plantain and banana hybrids was investigated. Our aim was to provide information on plantain and banana peels that may circumvent huge losses during fruit processing by converting waste into wealth and health. Materials and methods. Four new plantain hybrids developed at the IITA, Nigeria, named PITA 14, PITA 17, PITA 24 and PITA 26, one cooking banana hybrid (BITA 3) and an African plantain landrace, Agbagba, were investigated. Antinutrient and heavy metal contents of the dried peels from the different cultivars were determined and the data were statistically analyzed. Results and discussion. The plantain hybrid PITA 14 differed significantly from other cultivars in saponin, tannin and oxalate. A significant difference was observed between PITA 17 in phytate compared with other cultivars. Cyanogenic glucosides found in PITA 17, PITA 26 and BITA 3 differed significantly from the values obtained in other cultivars. Both BITA 3 and Agbagba are significantly different from other cultivars in phenolic content, while PITA 24 and Agbagba differed significantly from other cultivars in lead. PITA 24 peels differed significantly from other cultivars in cadmium, but no significant difference was found among the different Musa varieties in mercury. Conclusion. In spite of the antinutritional properties ascribed to the various constituents investigated, the levels found in the peels of new Musa hybrids suggest that new varieties might not constitute a health hazard when ingested. Plantain and banana peels may be converted into livestock feeds, which will eventually provide protein and other nutrients to humans from consumption of meat and other products derived from the animals.
