Certain variety of plants such as vegetables, spices and seaweed are abundantly being grown in high altitude cold desert region of Tawang in Arunachal Pradesh, India. Therefore, five different vegetables, spices and seaweed were taken from that particular cold region viz., finger millet, nori seaweed, pepper corn, bean and mushroom have been selected based on the higher consumption of people of Northeast (NE) India for the proximate analysis, mineral, antioxidant and vitamin contents. So far, there is no nutritional composition studies have been carried out with available vegetables, spices and seaweeds growing in NE. For this reason, this study was undertaken to determine the macro and micro nutrients and antioxidant potential of these plant foods. Different analyzed varieties were significantly different for proximate composition and mineral content, and each variety showed significant differences. Common bean showed higher percentage of protein with 35.09% and fat percentage of the finger millet is higher (9.2%) as compared to other varieties from other regions (1-1.5%). Higher crude fibre was assessed in mushroom with 47.77% followed with pepper corn (38.42%), bean with 30.987%, and finger millet (5.14%).Calcium was higher in finger millet with 225 mg per 100g whereas iron content was higher in mushroom with 652 mg followed with beans (543 mg), pepper corn (408 mg per 100g). Higher amount of polyphenols observed in finger millet with 8.716 µg (GAE)/mg and highest total flavonoids in pepper corn with 48.196 µg (RU)/ml. Likewise, highest FRAP in finger millet noticed with 72.0 µg of FeSO4 equivalent /mg and reducing power (ascorbic acid equivalent /mg) in mushroom (244.0) and pepper corn (242.0). All samples had higher metal chelating activity between 86.657- 83.383 IC50 µg. Similarly, higher amount of vit B6 was noted in pepper corn with 197.0 mg while lowest in seaweed with 1.76 mg/100gm.

The aim of determining the proximate composition of red and black finger millet/Tamba (Eleusine coracana) varieties was to ascertain their nutritional composition and their ability to be used as feed ingredients. The finger millets used in this experiment were purchased from local markets in Ganawuri of Plateau and Manchok in Kaduna States and were subjected to proximate analysis. The results revealed that the millets contained Dry Matter – 88.48 and 87.55 %; Crude Protein (CP) – 13.98 and 13.14 %; Ether Extract (EE) – 3.70 and 3.10 %; Crude Fiber (CF) – 6.67 and 7.02 %; Ash – 4.90 and 4.36 %; Nitrogen Free Extract (NFE) – 59.22 and 59.84 % for the red and black finger millets, respectively. Based on these results, it can be concluded that finger millet is a nutritious feed resource irrespective of the variety and can be incorporated into animal feed in the livestock industry. It is recommended for farmers to use the crop by incorporating into livestock feed because of its rich proximate composition.   L'objectif de la détermination de la composition immédiate des variétés de mil rouge et noir / Tamba (Eleusinecoracana) était de vérifier leur composition nutritionnelle et leur capacité à être utilisées comme ingrédients alimentaires. Des variétés de mil rouge et noir utilisées dans cette expérience ont été achetées aux marchés locaux de Ganawuri de l'état de Plateau et de Manchok del'état de Kaduna et ont été soumises à une analyse immédiate. Les résultats ont révélé que les variétés de mil contenaient de la matière sèche - 88,48 et 87,55% ; Protéine Brute (PB) –13,98 et 13,14% ; Extrait d'éther (EE) –3,70 et 3,10% ; le 'crude fibre' (CF) –6,67 et 7,02% ; Cendres – 4,90 et 4,36% ; Extrait sans azote (le 'NFE') –59,22 et 59,84% pour les mil rouges et noirs, respectivement. Sur la base de ces résultats, on peut conclure que le mil rouge et noir est une ressource alimentaire nutritive quelle que soit la variété et peut être incorporée dans l'alimentation animale dans l'industrie de l'élevage. Il est recommandé aux agriculteurs d'utiliser la culture en l'incorporant dans l'alimentation du bétail en raison de sa riche composition immédiate.

Aim: Citrullus lanatus is a fruit widely consumed for its pulp though incompletely, as its other parts (seed and rind) are discarded and may possibly offer bioactive compounds involved in ameliorating certain disease conditions. Hence, this study aimed at comparatively investigating the nutritional composition and antioxidant properties of the seed, pulp and rind of C. lanatus so as to inform the inclusion of these different parts into the fare of the people. Methodology: Standard analytical methods of Association of Official Analytical Chemists were used to determine proximate, phytochemical, vitamin, mineral and antioxidant aspects of the fruit parts. The results were analyzed using Student’s t-test at .05. Results: The proximate analysis showed a high moisture value in the pulp (93.34 +/- .82) followed by the rind (77.11 +/- 3.44) and the seed (10.00 +/- .48). High crude protein and fiber contents were both noted in the seed followed by the rind and pulp. Mineral determinations revealed potassium to be abundant in the rind (452.31mg/kg) than the seed (305.7mg/kg) and the pulp (100.5mg/kg), followed by calcium occurring more in the rind (292.61mg/kg) than in the pulp (257.21mg/kg) and seed (227.45mg/kg) and then manganese being the least concentrated among the minerals. The investigated phytochemical principles revealed the highest concentration of cardiac glycosides in the seed (14.82 +/- .66) than the rind (1.95 +/- 0.80) and pulp (1.10 +/- 0.17), followed by saponins occurring most in the rind (12.05 +/- 3.91) than the seed (10.17 +/- 0.63) and pulp (.13 +/- .01). The seed had the highest DPPH scavenging activity followed by the rind and pulp respectively. The seed also showed a higher reducing power and lipid peroxidation capacities than the other fruit parts suggesting a potent property for antioxidant activity in the fruit parts of C. lanatus. Conclusion: The findings imply that both seed and rind of C. lanatus can be good sources of nutritional, phytochemical and antioxidant components in addition to the pulp which is commonly consumed and these may be implicated in management of certain diseases with further evidential research.

The nutritional and mycoflora changes in dried African yam beans (Sphenostylis stenocarpa) were investigated during a storage period of twenty weeks. The result of the proximate analysis (g/100 g) showed that the following moisture content decreased from 11.15-9.80, fat 1.25-0.49, crude fibre 6.18-2.64, crude protein 77.92-62.14 while the ash content increased from 3.20-3.78, carbohydrate content 0.36-18.32. The mineral analysis (mg/100 g) showed a decrease in all parameters investigated, sodium (Na) 2.57-1.35, potassium (K) 42.26-31.75, calcium (Ca) 21.45-12.56, magnesium (Mg) 27.75-20.72, iron (Fe) 0.25-0.12, zinc (Zn) 0.06-0.05, copper (Cu) 0.03-0.03, phosphorus (P) 32.08-22.03, manganese (Mn) 0.11-0.06, chromium (Cr) 0.002-0.001. Lead (Pb), cadmium (Cd) and nickel (Ni) were not detected. Five fungi comprising four genera were isolated using direct plating, washing and dilution methods on Potato Dextrose Agar (PDA), and identified using their cultural and morphological features with reference to standard procedures. The fungi isolated were Aspergillus niger, Aspergillus flavus, Penicillium sp., Mucor sp. and Phytophthora palmivora. It can be concluded that storage encourages proliferation of mycoflora thereby leading to reduction in the nutritional and mineral composition of the stored sample.

This study was carried out to investigate the mycoflora and nutritional composition of smoked dried crayfish Penaeus monodon (prawns) during storage for twenty-four weeks. The mycoflora were isolated at four weeks interval using direct plating and dilution methods on Potato Dextrose Agar (PDA), Saboraud Dextrose Agar (SDA) and Malt Extract Agar (MEA). The fungi isolated using direct plating methods and dilution methods were Aspergillus niger, Aspergillus flavus, Aspergillus fumigates, Rhizopus sp., Phytophthora siskiyouensis, Penicillum sp. and Mucor sp. The result of proximate analysis (g/100 g) of smoked dried crayfish Penaeus monodon (prawns) showed a decrease in ash content (12.53-10.86), fat (14.95-12.30), crude fibre (1.60-1.29) while moisture content (3.10-3.71), crude protein (66.34-66.84) and carbohydrate (1.66-5.00) increased respectively. The result of mineral analysis (mg/100 g) of smoked dried crayfish Penaeus monodon (prawns) showed a decrease in Sodium (110.90-104.9), Potassium (107.30-94.96), Calcium (120.61-98.66), Magnesium (137.50-120.22), Zinc (2.15-1.87), Iron (12.33-10.17), Copper (0.16-0.22), Manganese (0.40-0.25), cadmium (0.42-0.13) and Phosphorous (485.00-460.76) respectively. This study showed that the smoked dried crayfish products were invaded by fungi which could be due to display of the products in open trays without coverage for sale, most of the times which were not hygienic. This, in turn, allows the dust and fungal spores to settle on the products leading to fungal contamination, production of toxins and spoilage. Stored smoked dried crayfish (prawns) sellers should be enlightened on good hygienic practices.

Full Fat Soy Flour

The effect of full-fat soy flour as an extender on the nutritional composition and sensory properties of cooked beef sausage was investigated. Sausage samples were produced using beef and full-fat soy flour (FFSF) as extender at 5%, 10% and 15% substitution levels while 100% beef sausage served as the control. The proximate, mineral and vitamin composition as well as sensory properties of the formulated sausages were determined using standard methods. Proximate analysis revealed an increase in moisture content (63.66-65.59%), protein (15.87-17.66%) and fat (4.22-6.37%) as beef was partially replaced with FFSF. Ash content also increased but at 15% FFSF, a decrease which was not significantly (p>0.05) different from control sample was observed. Crude fibre content was highest for sausage extended with 15% FFSF (1.03%) while carbohydrate content decreased significantly (11.93-7.25%) on partial replacement with FFSF. Mineral results showed a significant (p<0.05) increase in magnesium (9.80-15.34 mg/100 g) and decrease in zinc (0.92-0.79 mg/100 g) as beef was partially replaced with FFSF. Calcium, sodium and phosphorus contents of beef sausages extended with 10% FFSF (18.74 mg/100 g, 52.78 mg/100 g and 95.82 mg/100 g, respectively) were significantly (p<0.05) higher than other sausage samples. Vitamin analysis also revealed a significant (p<0.05) increase in vitamin A (4.23-5.32µg/100g) while vitamin B3 (0.037-0.033 mg/100 g) and vitamin B1 (0.023-0.013 mg/100 g) decreased as beef was extended with FFSF. Vitamin C content of sausage extended with 10% FFSF (2.76 mg/100 g) was significantly (p<0.05) higher than other samples. This same trend was observed for vitamin B2 content of sausage with 15% FFSF (0.034 mg/100 g). FFSF had no significant effect (p>0.05) on the sensory properties of the sausages. Thus, the use of full fat soy flour as an extender for cooked beef sausages is feasible as this will reduce the amount of meat used, thereby reducing the cost of the cooked beef sausage and at same time producing nutritious sausages.

Beneficial properties of shade trees of tea plantations other than their medicinal properties have been extensively studied. This research was initiated to explore the properties of some shade trees with special emphasis on their antioxidant and antibacterial properties. Leaves from shade tree like Dalbergia sissoo (DS), Cassia siamea (CS), Derris robusta (DR), Leucaena leucocephala (LL), Acacia lenticularis (AL) and Melia azedarach (MA) were used for the study. Characterization of shade tree leaves by determination of moisture, crude fibre and ash content and tests of non polar – polar solvent extracts for steroid, tannins, cardiac glycosides and coumarin, free radical scavenging, ferric reducing power, NO scavenging activities, quantification of Flavonoids and antibacterial activity were conducted. The average moisture, crude fibre and ash percentage of shade tree plants were found to be 62.95, 11.28 and 1.86 respectively. Methanol, ethanol, acetone and ethyl acetate respectively proved to be the most potent solvent for various phytochemical extractions as it gave positive results for tests like tannin, steroid, cardiac glycosides and coumarin. AL (91.46%), DR (92.69%), LL (94.32%) and MA (93.34%) leaf extracts showed a high level of DPPH scavenging activity in their water extracts. In DS (88.11%) and CS (83.23%) maximum DPPH scavenging activity was observed in Diethyl ether and Methanol extracts respectively.  Acetone extracts were more active than the water extracts in exhibiting ferric reducing power and NO scavenging activity. Summation of the quantity revealed that DS showed maximum presence of flavonoids and acetone as most potential for isolation of flavonoids. The decreasing order of summative antibacterial activity was recorded in DS, followed by CS, DR, AL, MA and LL. Chloroform showed the highest summative inhibition zone followed by ethanol, ethyl acetate, diethyl ether, acetone, water,  hexane, benzene and methanol. The antioxidant and antibacterial potential of shade trees were established.

Emulsified Meat

Frankfurters are the most widespread type of emulsified meat product in the world. However, they could be considered unhealthy due to their high-fat content (15–30%). The meat industry wishes to change the perception of these products by reformulating them. One strategy is increasing the content of compounds considered beneficial for human health. Thus, the aim of this study was to determine the chemical, physico-chemical, and sensorial properties of Frankfurter-type sausages added with roselle (Hibiscus sabdariffa L.), extracts. Frankfurter-type sausages were made following a traditional formula. Three different formulations were prepared. The original mixture was used as a control sample (CS). The other samples were formulated by adding roselle extract at 4.08% (FRE4) and 8.17% (FRE8). For proximate analysis, no statistical differences were found between FRE4 and FRE8 and CS. However, the residual nitrite levels decreased from 88.41 mg NaNO2/kg in CS to 86.31 and 69.82 mg NaNO2/kg in FRE4 and FRE8, respectively. Regarding the sensory analysis of the frankfurters, CS and FRE4 samples generally scored significantly higher than FRE8 for all the parameters considered. This study suggests that the reformulation of Frankfurter-type sausages using roselle extracts is feasible and represents a viable alternative to improve the safety and the nutritional composition of the product.
