Proximate Composition and Mineral Profile of Snail Meat from Different Breeds of Land Snail in Nigeria
O.O. Babalola,A.O. Akinsoyinu
Pakistan Journal of Nutrition , 2009,
Abstract: Four different breeds of snail, Archachatina Marginata (AM), Achatina Achatina (AA), Achatina Fulica (AF) and Limicolaria species (LM) were analyzed for proximate composition and mineral profile of the snail flesh (foot or edible potion). Proximate analysis of the snail flesh revealed that moisture was highest in LM (84.91%) and least in AM (73.67%). The crude protein contents of the breeds were significantly different from one another (p<0.05). The values ranged from 19.53% for AM to 5.86% for LM. The ash and ether extract of AM and AA were significantly higher (p<0.05) than that of AF, while LM had the least. AF had the highest Nitrogen Free Extract (NFE) while the least was observed in AM. The NFE and ether extract (fat) contents were generally low. The result of the mineral profile showed that AM recorded highest value (mg/100 g) in Calcium (126.40), Iron (2.29), Phosphorous (22.91), Magnesium (25.01) and Copper (1.03) while LM had the least values of 36.20, 0.72, 8.98, 5.28 and 0.29 respectively. These values across breeds for all the minerals analyzed were significantly different (p<0.05) from one another with the following trend AM>AA>AF>LM. There was no detection of lead and mercury in any of the samples. The result of the study showed that the African giant land snail, Archachatina marginata, apart from having size advantage is the favoured breed based on its nutritional superiority.
Proximate, Mineral and Biochemical Evaluation of the Haemolymph of Growing Snails Fed Fresh Lettuce Waste, Whole Lettuce, Pawpaw Leaves and Cabbage Waste
O.O. Babalola,A.O. Akinsoyinu
Asian Journal of Agricultural Sciences , 2011,
Abstract: Disease states in experimental animals are usually accompanied by biochemical alterations. Thus a good working knowledge of reference values of some biochemical constituent of the haemolymph of snails (Archachatina marginata) is needed as reference point for future researchers on snail. It is also necessary to determine whether these values could be influenced by diets. Thirty six experimental snails of mean weight of 125.64±2.35g were randomly distributed into 4 dietary treatments of Pawpaw Leaves (PL), Whole Lettuce (WL), Lettuce Wastes (LW) and Cabbage Wastes (CW). Nine snails were used as control animals to determine the reference values. They were fed ad libitum for 60 days. Parameters determined were, proximate composition, mineral profile, total protein, albumin, globulin, albumin:globulin, alanine amino transferase (ALT) and aspartate amino transferase. There was significant (p<0.05) reduction in crude protein of haemolymph from 24.14 to 21.20% for snails fed LW. The increase in ash from 0.79 to 0.84 in snails fed LW was significant. There were significant increases in all the minerals analyzed in all the treatment groups with Calcium recording the highest concentration of 170 mg/mL. There was also significant (p<0.05) decrease in albumin and albumin:globulin when snails were fed the experimental diets. Values obtained for the enzymes, ALT and AST between treatments were similar. The study established that the feedstuffs were safe for their consumption and could not lead to any tissue damage. Values of 165 unit/l for AST, 11 units/l for ALT, total protein, 7.1 g/dl, globulin, 3.9 g/dl, albumin, 3.2 g/dl, and albumin:globulin, 0.82 could serve as reference values.

World Journal of Agricultural Sciences , 2005,
Abstract: An investigation was carried out to evaluate the chemical and organoleptic properties of pawpaw and guava leathers. Guava leather was significantly higher in protein (2.67%) and fat (1.37%) than other samples. There was no significance difference in the crude fibre of pawpaw (2.4%) and guava (2.67%) leathers. This was also observed in the ash contents with pawpaw leather having (2.67%) and guava leather (2.87%). Guava leather is significantly higher in fruitiness smell and overall acceptability. Guava leather showed better compositional attributes.

S.O. Babalola, A.O Babalola, O.C. Aworh
Journal of Food Technology in Africa , 2001,
Abstract: In this study, chemical and mineral composition of the calyces of green, red and dark red roselle were evaluated. There was no significant difference in crude protein of green (17.9%) and red (17.4%) coloured roselle calyces. Crude fibre (11.2%), ascorbic acid (86.5mg/100g) and sodium (9.5mg/100g) contents of green coloured calyx were significantly higher than other calyx samples. However, dark red calyx was significantly higher in ash (6.8%) and potassium (2320mg/100g) contents than the other two calyces. Also, there was no significant differences in calcium, magnesium and zinc contents of red and dark red coloured roselle calyces at P Roselle calyces appeared to be cheap source of vegetable protein, fat and minerals therefore its consumption should be encouraged.

Numerical Computations to Produce Cokeable Coal Blends at The Ajaokuta Steel Plant, Nigeria  [PDF]
A.O. ADELEKE, P. ONUMANYI
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2007, DOI: 10.4236/jmmce.2007.62010
Abstract: A mathematical model and its associated numerical search algorithm has been developed for routine coal blending to include local coals for cokemaking at the Nigerian blast furnace-based Ajaokuta Steel Plant. A typical binary blend proposed using the model includes 28.38% and 29.00% of the ash- laden Lafia and non-caking Okaba coals, respectively. The proposed blends satisfy basic chemical and mechanical strength requirements at the lowest cost per ton of coal. The blending calculations showed that only low ash, low sulphur, medium volatile and high vitrinite reflectance prime grade coals such as the UK Ogmore should be imported for blending with the ash-laden medium coking Lafia coal. When the proposed blends are successfully confirmed with bench and pilot scale carbonization tests, cokemaking at Ajaokuta will be conducted with substantial savings in foreign exchange.

Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2008, DOI: 10.4236/jmmce.2008.74027
Abstract: The weakly caking Australian Agro-Allied coal sample mixed with 7% un-reactive coke breeze was subjected to stamped charging prior to carbonization for 22 hours in a 250kg pilot plant to improve the resulting coke strength. The coal was carbonized with a bulk density of 1,000kg/m3 and heating flue temperature of 1,340℃. The screen distribution analysis and the micum tests conducted on the coke gave M10 and M40 of 15.90% and 73.20%, respectively. These results show that the Agro-Allied coke produced is inferior to the coke from a normal top charged counterpart with M10 and M40 indices of 15.40% and 78.20%, respectively and do not satisfy the requirements for the blast furnace ironmaking process. These results thus suggest that the stamped charging coking improvement method designed for high caking, high volatile coals may not be able to improve the strength of coke resulting from a weakly caking, medium volatile coal mixed with coke breeze.
