Abstract

Atlantic mackerel (Scomber scombrus) and Atlantic horse mackerel (Trachurus trachurus), locally known as kote, are fishery species consumed in Nigeria due to their high nutritional values. This research determined the nutritional composition of the local dried fish, Scomber scombrus and Trachurus trachurus. Results for Scomber scombrus shows the mean value of the moisture, ash, crude fat, crude fiber, and crude protein contents in percent (%) as: 5.26±0.00, 5.20±0.10, 35.60±0.00, 2.90±0.10 and 46.30±0.01 respectively. For Trachurus trachurus, the moisture, ash, crude fat, crude fiber, and crude protein contents in percent (%) were 9.52±0.00, 32.26±0.01, 24.14±0.00, 11.91±0.85 and 40.95±0.00 respectively. The mineral composition of Scomber scombrus was as follows: Sodium (Na) had the highest mineral composition with 78.90 mg/100g, followed by magnesium (Mg) with 15.90 mg/100g, manganese (Mn) with 0.86 mg/100g, zinc (Zn) with 0.282 mg/100g, and iron (Fe) with 0.10 mg/100g. Trachurus trachurus has magnesium (Mg) at 27.00 mg/100g as its highest mineral composition, followed by sodium (Na) at 22.50 mg/100g, zinc (Zn), iron (Fe) at 0.17 mg/100g, and manganese (Mn) at 0.09 mg/100g. It is concluded from the study, that Scomber scombrus and Trachurus trachurus are good sources of essential nitrates, fat, proteins containing essential amino acids, and other micronutrients that are beneficial to human health.

Abstract

Effect of processing on the nutritional composition of groundnut seeds were carried out using standard analytical methods. Raw, boiled and fried groundnut seeds were analyzed for proximate composition, mineral contents, and phytochemical screening. The result reported that the raw, boiled, and fried contains (5.357±0.190%, 4.545±0.050% and 3.896±0.015%, moisture contents), (2.401±0.011%, 3.225±0.004% and 2.816±0.001%, ash contents), (46.591±0.001%, 25.333±0.003% and 48.012±0.953%, crude fat), (4.126±0.887%, 15.001±0.030% and 7.692±0.002%, crude fibre), (19.520±0.040%, 21.580±0.040% and 23.540±0.000%, crude protein), (22.005±0.587%, 30.316±0.056% and 14.044±0.939%, carbohydrate) respectively. A significant difference was observed. Processing has significant effects on the mineral components of the seeds. The results revealed that raw, boiled and fried contains (56.900mg/100g, 48.400mg/100g and 35.00mg/100g Sodium), (0.215mg/100g, 0.185mg/100g and 0.540mg/100g Zinc), (65.500mg/100g, 42.700mg/100g and 25.500mg/100g Magnesium), (0.218mg/100g, 0.230mg/100g and 0.230mg/100g Iron), (0.250mg/100g, 0.110mg/100g and 0.100mg/100g Manganese). The phytochemical screening shows the presence of alkaloids, carbohydrates and proteins in all the samples and the result reveals that processing does not really have effect on phytochemical constituents. The investigation shows that fresh groundnut is a good source of mineral content, while raw and processed groundnut is a good source of some phytochemical constituents and processed groundnut is a good source of protein, fat, and carbohydrate with high nutritional value.

Abstract

The prevalence of multiple drug resistance among human pathogenic bacteria necessitates a continual search for new antimicrobial medicines, particularly among plants that are frequently farmed or naturally found in our surroundings. The study aims to investigate the inhibitory effect of garlic, ginger, and mushroom extracts at different concentrations against some clinical isolates. Anti-bacterial components from mushrooms, garlic, and ginger were extracted with hot water, cold water, ethanol, and acetone, and their anti-bacterial activity was determined using the agar well diffusion method. Zones of inhibition were observed primarily on hot water extracts of mushrooms (Pleurotus ostreatus) on culture plates inoculated with Staphylococcus aureus, Escherichia coli, and Klebsiella pneumonia at 370C for 24 hours. The cold water extracts of the mushroom (Pleurotus ostreatus) gave the highest zone of inhibition of 14.0±1.0mm when used against S. aureus. For spices, the cold water extracts yielded the highest zones of inhibition of 22.0±1.0mm followed by 16.0±1.0mm as observed with ginger. The results obtained have shown clearly that the mushrooms (Pleurotus ostreatus), garlic (Allium sativum), and ginger (Zingiber officinale) extracts contain phytochemicals with some antimicrobial activities. The water extracts of the mushrooms and spices showed broad-spectrum antimicrobial activity much more than ethanol and acetone extracts. The antimicrobial activities of mushroom and garlic extracts were highly effective against the bacterial pathogens studied. However, the antimicrobial activity of the ginger extract was poor. To address the multi-drug resistance to antibiotics, I recommend: that bioactive compounds found in mushrooms, ginger, and garlic be patented and used as alternative antimicrobials.
