Effect of Domestic Processing Method on the Proximate and Anti-Nutritional Components of Cnidoscolus Aconitifolius Leaf. (Published)

The effect of domestic processing method on the proximate and anti-nutritional content of the leaf of Cnidoscolus aconitifolius was properly investigated using standard method. The proximate result shows that there were high content of ash, protein, fibre, and carbohydrate, with ranges of 2.20±0.6-2.67±0.5, 2.91±3.0-3.60±1.0, 1.43±0.1-2.50±0.1 and 8.79±2.6-9.65±1.6 respectively and fat between 78.33±0.10-86.30±0.28. Little concentrations of phytate, oxalate and tannin, with ranges of 0.22 ± 0.01% – 0.35% ± 0.01%, 0.14 ± 0.02% – 0.41 ± 0.09% and 1.64 ± 0.03% – 1.94 ± 0.02% were observed. The concentrations of these anti-nutrients were controlled by the treatment process. This result proves that Cnidoscolus aconitifolius leaves has highly rich nutrients and therefore should be recommended for used as food condiments and feeds for farm animals. The treatment processes affected to a great extent the concentration of the anti-nutritional components of Cnidoscolusa conitifolius leaves.

Proximate Composition and Mineral Contents of Different Brands of Canned Fishes Marketed In Edo State Nigeria (Published)

Proximate composition and mineral content (Na, Ca, P and Mg) of fish is of great importance to fisheries managers, consumer and the nutritionist. In this study, seventeen different types of canned fish products were collected from super-stores and open market, proximate composition and the mineral elements (sodium, phosphorus, calcium and magnesium) of the different brands purchased were determined between January and September, 2015. The entire sample used were bought at the same time and kept at ambient room temperature, and every analysis was done in triplicate.  The results obtained showed that a gradual reduction in the food value (proximate composition) and the percentage mineral content of the different brands with a progressive reduction in the different months. Analysis of variance (ANOVA) and Duncan multiple range test (DMRT) at 5% level of significance, revealed that there were significant differences in the proximate and mineral components of the different brands and among the months, although some of these parameters were not significantly different for some brands. Results obtained from correlation analysis during the study revealed that there was a negative correlation relationship between fat/oil, fibre, nitrogen free extract (NFE) with moisture content, while there was also a positive significant relationship between protein/ash content, protein/moisture; also, a positive correlation existed between sodium, calcium, phosphorus and magnesium. The result obtained from this study indicates that these canned fishes analyzed were of high nutritional value and mineral content, but there is need to keep them at optimum temperature and not for too long in storage to enable consumer to derive the appropriate benefit from their consumption.

Effect of Size on Proximate Composition and Heavy Metal Content of the Mangrove Oyster Crassostrea gasar from the Andoni River, Nigeria (Published)

The proximate composition and heavy metal content of the mangrove oyster Crassostrea gasar from the Andoni River was investigated. Samples were categorized into three class sizes: small (< 25 mm), medium (25-50 mm), and large (> 50 mm) each with 10 sampling units for each class size. Differences across class size were significant for carbohydrate, lipid, and fiber content with their highest mean values recorded as 58.39 ± 0.21%, 6.70 ± 0.10% and 18.22 ± 0.28% respectively. Size-specific differences were detected only for concentrations of lead and zinc which showed maximum concentrations of 0.53 ± 0.02μg/g and 42.69 ± 1.81μg/g respectively. The proximate composition and heavy metal content recorded were generally higher in large-sized oysters and the variations observed were attributed to obvious differences in their class sizes. The remarkably low moisture content recorded in C. gasar was attributed to higher drying temperatures (105°C). Food quality and uptake of heavy metals in tissues of C. gasar generally varied along size gradients, with peak values in large-sized individuals. However, the levels of heavy metals recorded in soft tissues of C. gasar in this study were generally very low and fall within levels expected in tissues of aquatic biota.

Effect of Processing On the Nutritional and Anti Nutritional Properties of Canavalia Plagiosperma Piper Seeds (Published)

The effect of heat processing on the nutritional and anti nutritional qualities of oblique -seeded jack bean (Canavalia plagiosperma piper) was studied. Raw seeds of Canavalia plagiosperma (Oblique seeded Jack bean) were autoclaved (at 1210C, 15lb for 25, 30 and 35 minutes) and cooked (at 1000C for 30, 40 and 50 minutes). The proximate composition and anti-nutrients of the processed and raw samples were determined. The proximate composition showed that moisture content of raw seed was 8.26%, 35 minutes autoclaving increased it to 8.53% while 50 minutes cooking increased it to 8. 84%. Autoclaving reduced protein content from 31.54% to 31.28% while cooking reduced it from 31.54% to 28.86%. The ash content was reduced from 3.17% to 2.95% by autoclaving and from 3.17% to 2.51% by cooking. Autoclaving showed increasing effect on fat and energy content,(0.82-9.23%) and (1635.66-1637.94 KJ/g) respectively. The fibre content of the raw seed was found to be 0.94%, which was reduced to 0.88% by autoclaving and 0.62% by cooking. Cooking significantly increased the carbohydrate content (47.36-52.15%). The processing treatments showed significant effect (P≤0.05) on each parameter. Six (6) anti-nutrients (Saponin: 2.45%, Phytic acid: 3.15%, Tannin: 1.02%, Oxalate: 1.48%, Phenol: 0.34%, Trypsin Inhibitor: 11.53Tu/g) were determined in the raw seed. The six processing treatments given to the seed showed a general reduction trend on these six anti-nutrients at different rates and levels. From the results in Table 3 and 4, autoclaving was the best processing method for phytic acid, and phenol while cooking was the best processing method for tannin, trypsin inhibitor, saponin and oxalate.

FLAVOUR EXTRACTION FROM MONODORA MYRISTICA AND TETRAPLEURA TETRAPTERA AND PRODUCTION OF FLAVOURED POPCORN FROM THE EXTRACT (Published)

Monodora myristica and Tetrapleura tetraptera are cherished in many Nigerian dishes. However, these spices are still of low industrial and commercial value, hence the need to incorporate them into new food products. The ground samples of both spices were evaluated for proximate composition and sugar concentrations (Sucrose, fructose, and glucose) of T.tetraptera. The proximate composition of M.myristica, was found to be 3.48±0.01% moisture, 4.52±0.07% ash, 47.09±0.33% fat, 8.38±0.09% crude fibre, 27.57±0.10% crude protein, and 8.96±0.02% carbohydrate corresponding values for T.tetraptera were found to be 6.0±0.02% moisture, 4.90±0.03% ash, 24.33±0.05% fat, 3.30±0.12% crude fibre, 18.69±0.19% crude protein, and 42.78±0.01% carbohydrate. The T.tetraptera was also found to have appreciable concentrations of the sucrose, fructose and glucose sugars. The relative abundance of oil, hence, essential oil, justifies the use of the spices as sources of flavourings. Both ground spice samples were extracted separately with water and ethanol. The flavour extracts were used to season popcorn and the acceptability evaluated using sugar flavoured popcorn as control. The water extracts of both spices were preferred compared to their ethanol extracts. The results obtained confirm that flavouring agents can be derived from M.myristica and T.tetraptera for industrial and commercial use.

CHEMICAL COMPOSITIONS OF ARIL CAP OF AFRICAN OAK (AFZELIA AFRICANA) SEED (Published)

African oak is one of the underutilized legumes in Nigeria. Information on various parts of this legume is required to enhance its utilization in foods and food products. Feeding of fowls with the flour made from the aril cap of the seed showed no harmful effect on them. The flour was then analyzed for chemical properties. Proximate analysis showed that the cap was appreciable in protein (5.69%), fat (18.5%), carbohydrates (63.91%), and fibre (5.4%) but low in ash (1.5%). The value of each of the anti – nutrients analyzed was below the lethal level. Although the cap was found to be low in ash content, it had appreciable amounts of some essential elements. These are sodium (7.10±1.00), potassium (148.0±0.10), calcium (7.02±0.00), magnesium (109.12±1.02 ppm), phosphorus (11.20±1.10 ppm), and iron (0.25±0.02mg/g).The vitamin components of the cap determined were A (234.7±0.00µg/g), C (4.0±1.00mg/100g), E (1.1±0.02mg/100g) and the B – vitamins; B1, B2, B6 and B12 (2.0±1.01, 33.0±0.11, 4.3±1.00 and 4.8±0.10)mg/100g, showing good amounts of the vitamins. Due to high proximate, vitamins, minerals and insignificant anti – nutrient compositions of the aril cap of the African oak seed, it could be used in both human and animal foods. There is therefore a need for food industries and feed formulators to utilize the cap.
