OGE Arowosoge, OY Ogunsanwo, L Popoola
Journal of Agriculture and Social Research (JASR) , 2010,
Abstract: The utilization trend of four commonly used wood species and two lesser used wood species that are used for furniture making was examined. The wood species are Mansonia altissima (Mansonia), Khaya ivorensis (Khaya), Cordia millenii (Cordia) and Tectona grandis (Teak) as commonly used wood species; Aningeria robusta (Aningeria) and Gmelina arborea (Gmelina) as lesser used wood species. 154 small-scale furniture factories (SSFF), 28 medium-scale furniture factories (MSFF) and 11 large-scale furniture factories (LSFF) selected through stratified random sampling procedure in Lagos, Ibadan and Benin cities were considered for the study. The quantity (cubic meter) of the six wood species used in making interior furniture such as chair, table, bed cabinet, shelf, wardrobe cupboard and settee from 2001 to 2006 was obtained through a structured questionnaire. The study revealed that in SSFF, the utilization of Khaya, Cordia, Aningeria and Gmelina had been on the increase from year 2001 to 2006 while the trend for Mansonia and Teak did not follow a definite pattern. For MSFF, the trend showed that utilization of Khaya and Cordia increased from 2001 to 2004 and thereafter declined while that of Mansonia and Teak did not follow a definite trend for the 6 years considered for the study. However, Aningeria and Gmelina increased yearly from 2001 to 2006. For LSFF, no definite trend was observed in the utilization of Mansonia, Khaya, Cordia and Teak while Aningeria and Gmelina also increased yearly for the 6 years. The trend for the total wood utilization by the SSFF, MSFF and LSFF showed that Khaya was mostly used by the three scales of furniture industry, followed by Cordia while the utilization of Teak by the three scales of furniture industry was low for the six years of study. There is urgent need for a massive plantation establishment of Teak and Gmelina.

Extreme Life, Biospeology & Astrobiology , 2011,
Abstract: Tardigrades are polyextremophilic small organisms capable to survive in a variety of extremeconditions. By reversibly suspending their metabolism (cryptobiosis – tun state) tardigrades can dry orfreeze and, thus, survive the extreme conditions like very high or low pressure and temperatures,changes in salinity, lack of oxygen, lack of water, some noxious chemicals, boiling alcohol, even thevacuum of the outer space. Despite their peculiar morphology and amazing diversity of habitats,relatively little is known about these organisms. Tardigrades are considered some lesser known taxa.Studying tardigrades can teach us about the evolution of life on our planet, can help us understand whatextremophilic evolution and adaptation means and they can show us what forms of life may develop onother planets.

Advance Journal of Food Science and Technology , 2011,
Abstract: The Effects of blanching time and particle size on functional and pasting characteristics of some lesser known Nigerian yams were investigated. Two varieties of lesser known yam Ighu and Ona belonging to Dioscorea dometorum species and two varieties of commonly used yams ozibo and okwanankata belonging to the D. rotunda and D. alata sp., respectively. The yams were processed by peeling, cubing, and blanching at 100oC for 5 or 10 min, drying at 50oC and subsequently milled to flours and fractionated to 40, 60, or 80 mesh sizes. Another batch of the tubers were processed similarly, but they were not subjected to a blanching treatment. Swelling capacity, water absorption capacities, bulk density, solubility and pasting characteristics were evaluated. The result showed that the lesser known yam Ighu exhibited significantly higher (p<0.05) hot and cold paste viscosities, solubility, water absorption and swelling capacities than the common yam varieties. Hot and Cold paste viscosities, solubility, water absorption and swelling capacities of flour generally increased as particle size decreased in all the test samples. While the bulk density was not affected by the blanching treatment, it decreased with decrease in particle size. The yam starches generally showed weak stability,but starch of the lesser known variety Ona suffered the least share thinning . Rate of retrogradation was found to be high in all the yam varieties but more pronounced in the lesser known yams Ighu and Ona. Ighu starch which exhibited the highest cold and hot paste viscosity showed the highest setback and index of gelatinization values. Industrial and culinary applications of the test yam varieties were suggested.

Pakistan Journal of Nutrition , 2009,
Abstract: The cost of raw material needed for the production of animal feed has led to the evaluation and ascertaining the adequacy of some lesser known crop seeds for minerals composition and the possible effects of anti nutritional factors on the availability of the required nutrients. The mineral elements and anti nutritional factors Jatropha curcas, Trichosanthes cucumerina, Citrillius vulgaris, were determined using standard analytical methods. The concentration of copper (16.00 mg/kg-43.00 mg/kg), Zinc [33.00 mg/kg-45.00 mg/kg], Manganese [51.70 mg/kg-63.00 mg/kg], Potassium [8704.15 mg/kg-9246.33 mg/kg], Sodium [170v mg/kg-206. mg/kg], Phosphorus [322.20 mg/kg-411.60 mg/kg], Iron [133 mg/kg-187 mg/kg], Magnesium [1896.00 mg/kg-2394 mg/kg] and Calcium [1534.00 mg/kg-1826.00 mg/kg], varied significantly in the seeds respectively. The content of the minerals in metabolize state were greatly affected by the anti-nutritional factors, tannin [7.50 mg/100 g-25.30 mg/100 g], saponin [1100.00 mg/100 g-2097 mg/100 g], oxalate [17.40 mg/100 g-40.65 mg/100 g], nitrite [50.30 mg/100 g-57.30 mg/100 g], nitrate [9.00 mg/100 g-24.60 mg/100 g] and phytic acid [480.03 mg/100 g-2012.02 mg/100 g]. Concentration of mineral elements in all lesser known crop seeds are below the dietary requirements for animal.

Manjoosha Srivastava, Shailesh Kumar
Food and Nutrition Sciences (FNS) , 2013, DOI: 10.4236/fns.2013.49A1010
Abstract:

A. tortilis is commonly known as “Israeli babool”. The species is exposed to the world for its pods, gum and other aerial parts as fodder &feed for cattles. The plant was used as antidiabetic, antidiarrhoeal, antiasthmatic and also had several other medicinal benefits but the seed oil was not explored to the extent of its real potential. Hence the study was carried out to characterize the seed for oil and analysis of fatty acid composition through GC for quality control and maintenance. Commercial indices of oil were also estimated. Extracted oil is rich in Linolenic acid (50.43%) and Linoleic acid (36.74%). Beside this palmitic, stearic and oleic acid are other fatty acids identified. MUFA, PUFA, SFA and omega-6/ omega-3 ratio were also found to be promising for its potentiality in edible and clinical uses. The investigation thus scopes the utility of oil and prospects the lesser known plant seed as alternative oil source of nutritional and therapeutic importance.

Journal of Agricultural Science , 2012, DOI: 10.5539/jas.v4n10p212
Abstract: We carried out a study using key informant interviews, focus group discussions and individual interviews to explore opportunities to enhance innovation in the oil palm sector in Ghana. Current technical innovations at the farm level are insufficient to promote sustainable oil palm production and to alleviate poverty because of overriding institutional constraints at the larger-than-farm level. Oil palm was selected for the study for three main reasons: (1) It is considered a national priority crop because of its potential for reducing poverty, (2) It has a wide geographical coverage and (3) It is considered as both food and cash crop. Oil palm has evolved in the past 40 years from a public-sector to a private-sector crop. The study identified the following main actors in oil palm production: small private farms that produce about 80% of the crop; large-scale industrial estates with their network of smallholder and out-grower farmers who produce to supply their large-scale mechanized processing mills; small-scale semi-mechanized processing mills, medium-scale mechanized mills and secondary processors. Opportunities that will make it rational for farmers to invest in increased production and improved sustainability include: (1) creating institutional conditions that will enable small-scale processors to be integrated into the value chain; (2) organising farmers to be able to negotiate for better deals for themselves; (3) improve system of distribution of improved planting material in regions where accessibility to seedlings of the high-yielding tenera hybrid variety is difficult; and (4) developing new tenancy rules and arrangements that improve the income of tenant farmers and encourage them to invest in increased productivity.
Screening of Phytochemical Compounds and Toxic Proteinaceous Protease Inhibitor in Some Lesser-known Food Based Plants and Their Effects and Potential Applications in Food
International Journal of Food Science and Nutrition Engineering , 2012, DOI: 10.5923/j.food.20120203.01
Abstract: Compounds or substances which act to reduce nutrient intake, digestion, absorption and utilization and may produce other adverse effects are referred to as anti-nutrients or anti-nutritional factors. Plant sources contain in their raw state wide varieties of anti-nutrients which are potentially toxic. This study was conducted to phytochemical investigation on fruits and plants from India and Iran. Eight plant species were used. A qualitative phytochemical analysis was performed for the presence of polyphenols, saponins, alkaloids, phytic acid, trypsin inhibitor and saponins. The results obtained of the investigated plants showed that the all eight samples were found to be polyphenols but Solanum indicum contains highest value(7.02mg/g). All samples showed the presence of alkaloids, and showed presence of saponins except Alocacia and Asparagus and showed presence of steroids except Chlorophytum and Asparagus. Portulaca with(16.9 TIU/g) and Asparagus with(0.8 TIU/g) contain highest and lowest values of trypsin inhibitor respectively. The phytochemical screening revealed moderate phytate contents except solanum and portulaca. The plants are rich sources of polyphenols appear to have protective effects for human health. Trypsin inhibitor and phytic acid may play a role as an antioxidant in plants and may be beneficial to health when it is consumed.
