This study assessed the effects of total ochratoxins on the nutritional composition and functional properties of grain flours. The grains cowpea, sorghum, maize, groundnut, rice, millet, and acha were milled. The proximate composition, functional properties, as well as Total Ochratoxin levels, were determined. The effects of the Ochratoxins on the nutritional and functional properties of the grains were evaluated. Ochratoxin levels in grain flours ranged from 0.09 to 54.41 μg/kg and not seen in some rice samples. Most Total Ochratoxin levels found in the grains were beyond the WHO/EU/FAO permissible limit, 5.00 µg/kg. Groundnut and Cowpea have a significant high content of protein and fiber. Groundnut had the highest average fat content, 41.84 %. The ash content of the grains ranged from 0.73 to 3.61%. The presence of ochratoxins had a significant impact on the grain's carbohydrates, proteins, and fat. Their presence had moderate effects on crude fiber, ash, and functional properties and negligible effect on grain moisture.

Adlay is a nutritious grain that has the potential as an alternative food because it has a high protein and fat content of 14.10% and 7.90%, respectively. The use of Adlay as flour still has a weakness, namely the functional properties of Adlay flour such as low swelling power. One way to improve the characteristics of Adlay flour is by fermentation using Rhizopus oligosporus. The fermentation duration is the time that allows changes in the characteristics of the flour due to the fermentation. This study aims to determine the effect of differences in fermentation duration using Rhizopus oligosporus on the physical, chemical, and functional characteristics of Adlay flour produced from fermented Adlay seeds. This study used one factor, namely the lengths of fermentation for 0, 12, 24, 30, 36 and 48 hours. The analysis in this study included whiteness, yield, pH, water content, ash content, protein content, fat content, carbohydrate content, swelling power and solubility, oil holding capacity (OHC) and water holding capacity (WHC). The results have shown that the longer the fermentation duration the lower rate of whiteness, pH, yield, water content, fat content, and carbohydrate content will become, while some functional properties of Adlay flour become better with increasing values of ash content, protein content, swelling power, solubility, Oil Holding Capacity (OHC), and Water Holding Capacity (WHC).

The study was designed to investigate the effects of freezing periods and the combination of packaging with or without turmeric on the proximate composition of whole and sliced Labeo bata. The samples were subjected to 28 days of frozen (-20 °C) storage periods and analyzed for proximate composition such as moisture, protein, lipid and ash at intervals of 0, 14 and 28 days. Data obtained was subjected to analysis of variance (ANOVA) at 95% significant level. Different preservation periods and methods significantly affected the nutritional composition of fresh fish. Moisture, protein, lipid and ash content decreased with increasing storage periods when compared to the fresh fish as control. The highest percentage of protein was found in turmeric-treated whole fish preserved in polythene, C4, after the 14th (15.70±0.14) and 28th (15.27±0.21) day. On the other hand, the lowest percentage (14.01±0.10 and 13.22±0.18 for the 14th and 28th day, respectively) was found in sliced fish preserved without polythene, C5. In conclusion, the turmeric-treated whole fish preserved in polythene retained fish nutrients and ensured its good quality and composition longer than other treatments, thereby extending the shelf life during frozen storage.
