Effect of seasonal variation and farming systems on the properties of Nile tilapia gelatin extracted from scales.

Although fish gelatin has become a research hotspot in recent years, researchers and manufacturers are still looking for high-quality sources of fish galatin to meet the commercial demand for safer gelatin.became This study aimed to evaluate the impact of seasonal variation and farming systems on the properties of gelatin extracted from Nile tilapia scales. Gelatin extracted from farmed tilapia had lowest impurities, higher clarity as well as desirable color characteristics (L* = 65.

Incidences of aflatoxin contaminations in ingredients, feed and products of poultry from two regions in Ghana.

Commercial poultry feed required for proper growth of birds and egg production contains essential nutrients with maize as key component. Inadequately dried maize is prone to aflatoxin contamination and therefore when used in feed formulation for poultry may compromise the safety of the feeds and poultry products. This study investigated the levels of aflatoxins in feed ingredients, feed and poultry products sampled from Eastern and Greater -Accra regions of Ghana.

Impact of Different Oil Extraction Techniques on the Physicochemical Properties of Seed.

The seeds of baobab were found to have both industrial and domestic uses due to their essential oil qualities for topical medication. However, the seeds found in this study area in Ghana are underutilised and sometimes thrown away after being taken off the pulp. The present study is aimed at examining the impact of the two predominant techniques used for oil extraction from nonoily seeds, namely, mechanical extraction and Soxhlet (n-hexane) extraction, on both the oil yield and physicochemical properties of crude oil derived from baobab seeds.

Heavy metal, microbial and pesticides residue contaminations are limiting the potential consumption of green leafy vegetables in Ghana: An overview.

Green leafy vegetables (such as cocoyam ( spp) leaves, spinach ( spp), amaranths ( spp), roselle leaves ( spp), and lettuce ( spp)) form a major part of Ghanaian meals providing essential vitamin such as A, B and C and minerals including iron and calcium as well as essential bioactive compounds. However, the practices involved in the production, distribution and handling of these nutrient rich vegetables, by most value chain actors in Ghana, unfortunately pre-dispose them to contamination with pathogens, heavy metals and pesticides residues. These have therefore raised public health concerns regarding the safety and quality of these green leafy vegetables.

Effect of home processing methods on the levels of heavy metal contaminants in four food crops grown in and around two mining towns in Ghana.

Unregulated small-scale mining activities, by young untrained men using some poisonous chemicals, occur in several agricultural forest belts in Ghana. These activities contaminate water bodies in these areas, which happen to be the main farming sites where food crops are intensively cultivated. The presence of these heavy metal contaminants in popular food staples is therefore worrying because of its adverse health implications.
