This study analyses the different methods of preparation and the nutritional value of three Cameroonian dishes. These are: "Corn chaff", "Nnam Owondo/Ebobolo" and "Nnam Ngon/Ebobolo". "Corn chaff" is a mixture of corn (Z ea mays L.), beans (P haseolus vulgaris ) and palm oil ( Elaeis guinensis ). "Nnam Owondo/Ebobolo" is made up of groundnut paste ( Arachis hypogaea ) and cassava paste ( Manihot utilisima). "Nnam Ngon/Ebobolo" is made up of egusi paste ( Cucumeropsis mannii ) and cassava paste ( Manihot utilisima ). The moisture, ash, protein, lipid , fibre and carbohydrate contents were determined using standard methods. The mineral contents (magnesium, copper, iron and zinc) were determined by Atomic Absorption Spectrophotometry. A survey of these dishes in the market gave the quantity and the cost of each dish sold: A serving of "Corn chaff" which costs 200F CFA, weighs 641g; that of "Nnam Owondo/Ebobolo" which costs 150F CFA weighs 566g and that of "Nnam Ngon/Ebobolo" which costs 150F CFA weighs 507g. The proximate analysis gave the following nutritive content: moisture (67.9; 49.5 and 53.4 g/100g F.W), ash (4.30; 1.77 and 1.54 g/100g D.W), protein (11.7; 8.96 and 7.36 g/100g D.W), lipid (17.6; 13.5 and 7.79 g/100g D.W), fibre (3.18; 1.86 and 0.84 g/100g D.W), carbohydrate (63.3; 73.8 and 82.5 g/100g D.W), magnesium (95; 108.9 and 97.9 mg/100g D.W), copper (0.57; 0.27 and 0.23 mg/100g D.W), iron (6.08; 2.97 and 3,87 mg/100g D.W) and zinc (3.74; 3,29 and 3,14 mg/100g D.W) for "Corn chaff", "Nnam Owondo/Ebobolo" and "Nnam Ngon/Ebobolo" respectively. The content in nutrients shows that ′′ Corn chaff ′′ is balanced with respect to the proportions of protein, lipid and carbohydrate energy. On the other hand, "Nnam Owondo/Ebobolo" and "Nnam Ngon/Ebobolo" have low proportions of protein and lipid energy. The contents in minerals (Mg, Cu, Fe, and Zn) are low. Th e quantities actually ingested enable the coverage of 64; 69 and 45 % of the protein allowances and 31; 42 and 33% of the energy allowances for the tree dishes respectively, for an averagely active adult. For a good nutritional balance, it is recommended to consume a greater quantity of "Nnam Owondo " and "Nnam Ngon with smaller quantities of "Ebobolo".

Bananas and plantains (Musa sp.) are major staple foods in many developing countries of the world. Although bananas are rich in carbohydrate, fiber, protein, fat, and vitamins A, C, and B6 they are largely deficient of iron (Fe), iodine, and zinc (Zn). A small increase in the micronutrient content of bananas could play a major role in combating disorders that are due to deficiency of mineral micronutrients such as Fe and Zn. The objective of this study was to determine the Fe and Zn content of 47 banana genotypes from a germplasm collection in Uganda using atomic absorption spectrophotometry. The Fe and Zn content showed wide variability and highly significant differences (P < 0.001) within and among the different banana categories selected for this study. The highest average Fe content (1.42 mg/100 g) was found in ‘Saba’ (ABB) while the least Fe content (0.06 mg/100 g) was found in ‘Kikundi’ (AAA). The highest average Zn content (1.21 mg/100 g) among the analyzed accessions was found in ‘Kivuvu’ (ABB) while Zn was not detectable in both ‘Kabucuragye’ (AAA) and ‘Grand Naine’ (AAA). Considering these figures, there is a greater than 20-fold variation in the Fe and Zn levels of the banana genotypes used this study suggesting that genetic improvement of genotypes for enhanced micronutrient levels may be achieved by breeding.

Content of 16 essential elements was determined in three kinds of frankfurters by atomic absorption spectrophotometry. The element content of frankfurter batter was compared with processed frankfurters. There were larger (P&lt;0.05) amounts of sodium in beef; colbalt, manganese and sodium in chicken; and manganese, potassium and sodium in meat frankfurters (beef and pork) after processing. Chicken samples contained less (P&lt;0.05) chloride and potassium after processing. All frankfurters studied were superior sources of iron and zinc and fair sources of potassium when compared to other foodstuffs. Element retention ranged from 80.9% to over 100%. Data suggest that processing had minimal effects on element loss.

Abstract Water, chelate, and acid techniques were compared for the extraction of iron and zinc from fertilizer samples. The water and chelate extractions were studied to offer an alternative to the official final action acid extraction, 2.098(a)–(c); atomic absorption spectrophotometry was the determinative step. The results for 10 samples from 24 laboratories were examined statistically and were sufficiently reproducible for widespread use of the methods. Statistical treatment of the data from the proposed methods compared favorably with that from the official method. Both the water and chelate extraction techniques have been adopted as official first action, supplementary to 2.098.

The production and commercialization of Brazilian grape juice is increasing annually, mainly due to its typicality, quality, and nutritional value. The present research was carried out in view of the great significance of Brazilian grape juice for the grape and wine industry. The purpose of this study, therefore, was to assess its composition as well as the discrimination between grape juice and other beverages. Twenty four samples of whole, sweetened, and reprocessed grape juices, grape nectar, and grape beverage were evaluated. Classical variables were analyzed by means of physicochemical methods; tartaric and malic acids, by HPLC; methanol, by gas chromatography; minerals, by atomic absorption spectrophotometry. These products were discriminated by the Principal Component Analysis (PCA). Results show that whole and sweetened grape juices were discriminated from other grape products because they featured higher values of total soluble solids, tartaric and malic acids, most minerals, phenolic compounds, and K/Na ratio, whereas grape nectar and grape beverage presented higher values of ºBrix/titratable acidity ratio. Reprocessed juice was discriminated due to its higher concentrations of Li and Na and lower hue.

Micronutrient deficiency is raising concern worldwide, especially among children and pregnant women in Africa, Southern Asia, and certain developing countries, posing a significant risk to the nutritional status. This study aimed to develop cake fortified with Moringa leaf powder (MOLP), ripe banana flour (RBF) and assessed the effect of MOLP and RBF on the nutritional composition as well as consumer acceptability. The nutritional, mineral, vitamin A and sensory attributes of MOLP and RBF fortified cakes were assessed. Proximate analysis results showed that the addition of MOLP and RBF significantly increased from 5.79% to 8.90% for protein, 1.25% to 1.66% for ash, 2.70% to 6.98% for fiber, and 53.0% to 60.88% for carbohydrate. However, the fat and moisture content decreased from 20.16% to 13.06% and 17.77% to 13.54%, respectively. The mineral contents (phosphorus, potassium, iron, and zinc) increased significantly in the fortified cake compared to the unfortified control. The vitamin A content (3.40–5.62 mg/100 g) of the fortified cakes was significantly (p < 0.05) higher than the vitamin A (1.62 mg/100 g) content of the unfortified cake. Although MOLP and RBF substitution raised most of the nutritional contents, the maximum consumer acceptability was recorded in the unfortified control, which was statistically similar to C2 (1.5% MOLP and 2% RBF) substitution in terms of shape, sweetness, flavor, mouth feel, and overall acceptability. The results indicated that cake supplemented with 1.5% MOLP and 2% RBF provided the enriched nutritional quality and potentially contributed to the improvement of food and nutritional security of the vulnerable populations. Furthermore, utilizing ripe bananas with peels in cake recipes will help to encourage the recovery of food waste for functional food preparation.

Essential Heavy Metal

Berdasarkan hasil pengujian di laboratorium penguji Balai Pengkajin Teknologi Pertanian (BPTP) NTB bahwa batuan tambang yang ada di daerah Sekotong tidak hanya mengandung emas tetapi terdapat beberapa kandungan mineral lainnya seperti P, Zn, Fe, Cu, Al, dan S, metode yang digunakan dengan AAS (Atomic Absorption Spectrophotometry). Logam berat Fe merupakan logam berat essensial yang keberadaannya dalam jumlah tertentu sangat dibutuhkan oleh organisme hidup, namun dalam jumlah yang berlebih dapat menimbulkan efek racun. Untuk mengatasi masalah maka melakukan dua kegiatan yakni: a) penyuluhan tentang pentingnya kebersihan terhadap lingkungan. b) pembuatan saluran limbah agar tidak mencemari lingkungan yakni pembuatan kolam pengendapan (settling pond). Selain itu dari kolam pengendapan (settling pond) didapat lumpur dari sisa pengolahan atau penggelondongan emas, lumpur tersebut dapat dimanfaatkan menjadi barang bernilai ekonomi dan memiliki harga jual seperti bata tanpa bakar. Hasil dari kegiatan yang dilakukan yaitu pengetahuan masyarakat penambang tentang pentingnya lingkungan yang bersih dan kolam pengendapan (settling pond) dan kemampuan masyarakat tambang dalam mengolah limbah menjadi barang bernilai jual yaitu dengan membuat bata tanpa bakar. Keberhasilan dari kegiatan ini terlihat dari banyaknya masyarakat yang hadir dan antusiasnya mereka dalam mendukung kegiatan ini yakni dengan terjun langung membantu.Counseling and Making Settling Pond in an Effort to Reduce Mine Waste PollutionAbstractBased on the test results at the NTB Agricultural Technology Center (BPTP) examiner laboratory that mining rocks in the Sekotong area not only contain gold but there are several other mineral contents such as P, Zn, Fe, Cu, Al, and S, the method used with AAS (Atomic Absorption Spectrophotometry). Heavy metal Fe is an essential heavy metal whose existence in a certain amount is needed by living organisms, but in excessive amounts can cause toxic effects. To overcome the problem, two activities are carried out, namely: a) counseling about the importance of cleanliness to the environment. b) making sewage lines so as not to pollute the environment, namely the creation of settling ponds. Besides that, from settling ponds, sludge is obtained from the processing waste or gold rolling, the sludge can be utilized as economic value goods and has a selling price such as brick without burning. The results of the activities carried out are the knowledge of the mining community about the importance of a clean environment and settling ponds and the ability of the mining community to process waste into valuable goods, by making bricks without burning. The success of this activity can be seen from the large number of people present and their enthusiasm in supporting this activity by jumping in to help.
