Proximate composition of chapila fish (Gudusia chapra) was determined using two different treatments of smoke-drying. In salt treated smoke-dried chapila (S-C), moisture, crude protein, lipid and ash contents were found 5.31%, 46.47%, 29.05% and 19.92% respectively. The same parameters were 6.77%, 45.24%, 30.52% and 18.71% respectively in case of salt-garlic treated smokedried chapila (S+G-C) fish. During storage at room temperature (26-320C), the percentage of moisture was increased significantly whereas crude protein, lipid and ash contents were decreased. The values of moisture (%) content were increased 9.91% (8th months) in S-C and 10.74 % (16th months) in S+G-C respectively. The values of protein (%) content were decreased 44.81% (8th months) in S-C and 42.66% (16th months) in S+G-C respectively. Values of fat and ash (%) content were decreased 28.55% and 18.01% (8th months) respectively in S-C and 28.75% and 17.34% (16th months) respectively in S+G-C. The overall study showed that the smoke cured fish treated with salt-garlic had longer shelf life and found better for preservation.Bangladesh J. Zool. 42(2): 205-209, 2014

In the present study effect of processing treatments viz. blanching and germination on the proximate composition of Pennisetum glaucum (pearl millet) was studied. Proximate composition was analysed by the standard methods determined according to Association of Official Analytical Chemists. Results indicated that moisture content increased significantly after processing treatments. Blanching resulted in non significant increase in ash content of pearl millet grains. The crude protein content of unprocessed pearl millet was 11.55%. The crude protein content of blanched pearl millet grains was 11.27%. Crude protein content of germinated grains was found to be 12.38% as in comparison to 11.55% in unprocessed and 11.27 in blanching treatment. Crude fat content of unprocessed (control), blanched and germinated pearl millet grains were 5.36, 5.09 and 4.55%, respectively. Fiber content increased significantly after blanching and germination processing treatments. Processing treatments not only effect the nutritional composition of pearl millet but also contribute towards enhancement of shelf life.

The study aims at determining the physicochemical, proximate composition and the total viable count of Staphylococcus aureus in ‘Nono’ and yoghurt samples in Kaduna, Nigeria.Three hundred and eighty-four (384) fermented milk samples (Nono and yoghurt) were obtained from different selling points and were evaluated for the occurrence of S. aureus. The physicochemical and proximate analyses (pH, total titratable acidity, moisture content, ash content, protein content, and fat content) were determined. The results of the analyses showed that Nono had pH range of 3.56-3.61, total titratable acidity: 0.71-1.72, moisture content: 82.23-83.87%, ash content: 0.30-0.31%, crude protein content: 1.50-1.61%, crude fat content: 0.35-0.38 %. For yoghurt, the pH ranged from 3.76 -3.82, total titratable acidity: 1.10 -1.15, moisture content: 77.76-80.06%, ash content: 0.68- 0.70%, crude protein content: 3.40-3.45% and crude fat content: 1.76-1.79% from all the study areas. One hundred and four of the total samples were contaminated with S. aureus. Out of the 104 isolates of S. aureus that were isolated and identified, 88 were coagulase positive S.aureus. The Microgen Staph ID kit (Oxoid) was used to further confirm the characteristics of the 60 isolates of the coagulase positive S. aureus. The kit confirmed 43 isolates as S. aureus, the results indicated the presence of S. aureus in the milk samples which is of public health importance, as this can contribute to food-borne intoxication which can lead to food poisoning. There is a need for proper pasteurisation of raw milk to help eradicate S. aureus infection before human consumption.

This study investigated the effects of culinary methods (boiling and frying) on the proximate composition of an edible insect commonly known as African Palm Weevil (R. phoenicis) Larva(e). The proximate composition (moisture, ash, protein, crude fibre, fat and carbohydrate contents) were determined using standard methodology of the Association of Analytical Chemists (AOAC). Boiling increased the moisture and ash content but, decreased the protein, fat, carbohydrate (p0.05) and the fibre content compared to the raw sample. On the other hand, frying increased the protein and ash contents (p 0.05) but decreased the moisture, fat, carbohydrate and fibre contents compared to the raw. The decrease in moisture content led to a corresponding increase in the protein, and ash contents of the fried sample, which indicates high protein and mineral levels of the larvae. Also, the lowest moisture content recorded in the fried sample compared to the raw and boiled sample was an indication of reduction of microbial spoilage, and longer storage shelf life of this edible larva. Therefore, frying is recommended as the best culinary method for healthy diet.
