Egwujeh I.D. Simeon | Audu Basiru Danjuma | Amidu Momoh
The effect of cricket addition on the proximate composition, mineral compositions, functional and sensory properties of complementary food formulated from millet was studied. The result of the chemical composition showed significantly increase in the protein and fat level of the formulated complementary food (9.28±0.16 - 20.20±0.07) % and (3.65±002 - 8.12±0.08) %, respectively. However, a significant decrease in the carbohydrate level (75.61±0.03 - 60.44±0.31) g/100g was observed. Evaluation of functional properties showed that cricket addition did not affect the bulk density but increased the water absorption (2.46±0.05), Emulsion (38.02±0.40%), foam (6.00±0.00), gelation (20.00±0.00%) capacities and pH (6.20±0.02). The mineral contents including Fe, Ca, Na, and K of the food ranged from 7.54±0.10 - 10.25±0.05 mL/100g, 30.35±0.15 - 34.98±0.10 mL/100g, 9.35±0.29 - 14.47±0.06 mL/100g and 30.92±0.03 - 56.40±010 mL/100g respectively increasing with increased addition of cricket flour The formulated samples were rated higher for taste, colour, flavour, texture and the overall acceptability than the control. In general sample 513 containing 75:25 cricket: millet flour showed more improvement than other formulated samples and most acceptable in terms of taste, flavour mouth feel and overall acceptability. Adding cricket flour to millet flour as complementary food would help in addressing protein energy malnutrition in children.

The aim of this study was to evaluate the chemical composition and mineral bioavailability of T. tetraptera fruit pulp, an aromatic wild edible plant, using standard methods. The pulp were extracted from mature dried fruits obtained from plants at Awabo (5°30’14.2”N and 4°01’30.6”W) and Loviguié villages (5°48’24.5’’N and 4°20’15.8”W), all in south-eastern Côte d’Ivoire. The results of chemical analysis revealed that T. tetraptera fruit pulp contains carbohydrates (63.73±0.51%), crude protein (7.01±0.66%), crude fat (1.18±0.01%), ash (5.38±0.18%), fibre (11.78±0.02%), moisture (40.52±0.18%) and an energy value of 254.74±0.15 kcal/100g. Besides, the results showed a relative high amount of vitamin A (2.11±0.02%) and vitamin B9 (261.78±0.01 µg/100g) while vitamin E, B1 and B2 in trace concentration. Otherwise, the phytochemical analysis (mg/100g) based on dry weight revealed an appreciable amount of total phenol (2407.10±8.36), flavonoids (14.29±0.56), tannins (55.11±0.44), catechin (392.93±1.01) and also carotenoids (108.19±7.42 µg/100g). Organic acids profile (mg/100mL) showed citric acid (175.06±0.02) and salicylic acid (109.85±0.01) as major organic acids. Mineral composition (mg/100g) on dry weight basis revealed that potassium (1303.67±0.58) is the most abundant followed by phosphorus (303.33±5.77), calcium (187.33±0.58) and magnesium (141.33±0.57). Furthermore, the Phytates:Zn, Phytates:Ca, Oxalates:Ca and Phytates*Ca:Zn molar ratios recorded were all below than recommended threshold values, implying a bioavailability of zinc and calcium. These data indicate that the pulp of this fruit could be a good source of ingredient for both medicine and food industries in production.

Sun dried (T. fasciata) was stored with airtight polyethylene bags at room temperature to investigate the changes in physical, chemical, microbiological and sensory characteristics for 90 days. Sensory and physical (water reconstitution, pH) characteristics of dried T. fasciata showed that the product was acceptable up to 60 days of storage. Moisture content of T. fasciata was significantly increased from 15.06% to 17.80% during the storage period. No significant difference was observed in protein, lipid and ash content on dry matter basis during storage. However, amount of lipids of the dried fish was slightly decreased with the increasing of storage time. The pH value of dried T. fasciata was decreased significantly from 6.51 to 5.94 during the storage period. The peroxide value was increased from 13.84 to 27.87 meq/Kg of lipid. Similarly, acid value and conjugated diene of the lipids were increased significantly, and this result suggested that lipid oxidation occurred over this period of time. Microbial load was also increased from 1.13 to 8.37 log CFU/g with the increasing of storage time. Results of this study showed that the product was oxidized marginally during the storage period and suitable for human consumption up to 60 days.

In this study, 8 % ethanol extract of propolis prepared by mixing 920 ml of 70 % ethanol and 80 g of propolis was used. Chemical analysis of propolis extracts indicated that the propolis samples had high concentrations of the aromatic acids, esters and other derivatives which are responsible for the antibacterial, antifungal, antiviral, anti-inflammatory and anti-cancer properties of propolis such as benzyl cinnamate, methyl cinnamate, caffeic acid, cinnamyl cinnamate and cinnamoylglcine besides the most common compounds as fatty acid, terpenoids, esters, alcohols hydrocarbons and aromatic acids. Also, in this research the antifungal effects of 7 concentrations (6.25, 12.5, 25, 50 ppm) of propolis ethanol extract (PEE) against Fusarium oxysporum was investigated in vitro conditions. Propolis was mixed alone or in combination with potato dextrose agar (PDA) medium at various concentrations. The results indicated that the mycelial growth of the tested fungi decreased with each increase in PEE concentrations. Propolis extract collected from Muğla province showed 77.81% antifungal effect against Fusarium oxysporum at the highest concentration (50 ppm). The lowest antifungal effect (64.52%) against the pathogen was detected in the propolis extract collected from Denizli province.

Lupin seeds of genetically improved cultivar (Golo) were subjected to different processing methods and investigated according to anti-nutritional factors content and protein quality. Results showed that tannin content of raw seeds was significantly increased in sprouted and debittered seeds before and after boiling but in fermented seeds it declined significantly. Phytate content was significantly decreased in all processed seeds with a significant reduction observed in germinated seeds. The reduction in Phytate as a result of processing was accompanied by a significant improvement in protein digestibility. The protein content of lupin seeds decreased in sprouted seeds and increased in fermented and debittered ones. Boiling of the seeds even the sprouted ones significantly increased the protein content compared to raw lupin seeds. In raw lupin seeds, globulins comprised the major fraction followed by glutelin. Debittered seeds characterized by high glutelin, fermented are characterized by high globulin while germinated characterized by both fractions. Most of the amino acids level was increased after processing of the seeds.

Molasses, which is a traditional food substance obtained by boiling the fruit with local procedures and is abundantly eaten by Turkish people, are commonly produced from grapes. Zile, which is county of Tokat city placed in Central Black Sea region, is famous with molasses in Turkey. A special soil called as molasses soil containing CaO is added into to molasses in order to resolve acidification during production process. The purpose of this study is to determine the element concentration levels in grabe molasses soil samples collected from Zile by using energy dispersive X-ray fluorescence spectrometry (EDXRF). For this purpose, thirty-eight elements and eleven oxides were detected in molasses soil samples. The average concentrations of six major oxides (MgO, Al2O3, SiO2, K2O, CaO and Fe2O3) were found as 1.58%, 7.96%, 17.01%, 1.01%, 30.52% and 8.72%, respectively. Also, the average concentrations of three minor (Na2O, P2O5 ,TiO2) and two trace (SO3, MnO) oxides were found as 0.96%, 0.12%, 0.95% and 0.04%, 0.1%, respectively.
