Biotechnology has potential to enhance the production of agricultural and industrial products for achieving food security and economic development. In agriculture, biotechnology enhances the production of high yielding and disease resistance crops necessary for achieving food security and industrial development. This paper examines the constraints in the application of biotechnology research to the production of cassava in Nigeria. The study utilized primary data collected through questionnaire administration and interview from three research institutions working on cassava biotechnology in Nigeria. Findings showed that weak infrastructural facilities, poor funding, inadequate competent personnel and absence of appropriate legislation are the constraints in the application of biotechnology to cassava production in Nigeria. In addition, one out of the three research institutions has adequate and regular electricity supply through its own captive power plant while the remaining two research institutions relied more on electricity from the national grid. Inadequate funding and shortage of competent personnel were peculiar challenge confronting all the research institutions covered by the study. The study recommends improvement in electricity supply, production of more biotechnology scientists and adequate funding to enhance biotechnology research in Nigeria.

The present study is aimed at investigating the properties of Cassava starch for the production of adhesives as a career opportunity in chemistry education. Method of starch extraction, characterization and adhesive production for quality assessment was performed. The results showed that adhesives produced with sodium hydroxide as a gelatinization enhancer has a maximum drying time of 8.60 minutes and had a stronger bond. The work concludes that the adhesive produced is of good quality and can lead to re-inventing chemistry education as a career opportunity. However, the Cassava adhesive met the basic requirement for adhesive use and application. At the end recommendations were made, among others increase employment opportunities, also diversify the economic base of farmers and there is need for reorientation and attitudinal change towards entrepreneurial job.

White yam was fortified with cassava and plantain flours to develop a traditional food called ‘amala’. The fortified amala were subjected to organoleptic and chemical evaluations. Results showed that the protein and water absorption capacity of the fortified amala increased significantly. The panelists found yam fortified with plantain more acceptable. The samples stored in the refrigerator produced low pH values, remained fresh and maintained their attractive organoleptic attributes for a longer period than those stored at the room temperature.

The significance of rural poverty is underscored by the fact that a high percentage of the national population resides in the rural areas, is poor, and dependent on agriculture. The aim of this study is therefore to analyse the determinants of poverty status among cassava growing households in Oyo State, Nigeria. The specific objectives were to describe the socio-economic characteristics of the respondents, analyse the determinants of poverty status among the respondents, and examine the poverty profile of the respondents based on their income class. Descriptive statistics, Probit Regression analysis and Foster-Greer-Thorbecke (FGT) poverty measures were used to analyse the objectives, respectively. The result shows that number of years spent in school, household size and household assets were found to be the significant determinants of the poverty status of the respondents. Household size had a negative eff ect on the household’s poverty status, while household assets and years of schooling had positive effects on status. The results of the FGT measures show that poverty incidence, depth and severity are higher in the low-income class than in the high-income class. In conclusion, farmers who are members of larger households, those with little or no formal education and those with minimal assets were poorer than others. It is therefore recommended that a family-planning campaign and farmers’ educational programs should be intensified in the study area.

A survey in four distant locations: Anuradhapura, Madampe, Sri Jayewardenapura and Uda Walawe of Sri Lanka to identify the whitefly species related to cassava revealed two species, namely Bemisia tabaci (Gennadius) and Alerodicus dispersus (Russell). The species B. tabaci was recorded in all four surveyed locations, while A. dispersus was collected only from the first three locations. The results of the study on the pest life cycle under the laboratory conditions showed that, B. tabaci and A. dispersus passed through four nymphal instars before the adult stage. The mean duration values of these stages were 7.2, 7.5, 4.7, 5.6 and 8.5, 6, 9, 9 days respectively for the two species. The total duration of the life cycle of B. tabaci ranged from 22-57 days at the temperature of 29±2°C with a mean of 37.5 while that of A. dispersus was 27-68 days with a mean of 48 respectively (at 28±2°C). The damage to crop plants caused by two whitefly species is discussed with a special emphasis on their ability to transmit viral diseases.

Cassava-based maltodextrins with different dextrose equivalent (DE = 5, 10, 15 and 20) were prepared using two different enzymes, namely Termamyl 120L and Ban 480L (Novo Nordisk, Denmark). The molecular distribution oligosaccharide component (DP 1 - 7) was characterized and compared with commercial corn-based maltodextrin of the same DE. For all DE's, cassava-based maltodextrins prepared by Termamyl enzyme comprised more high molecular weight saccharides than corn-based maltodextrins. The profiles of saccharide component of cassava-based maltodextrin from Ban were comparable to those of corn-based ones. The shape and size of maltodextrins from two starch bases were different, presumably due to different processing. Corn-based maltodextrins were bigger in size. However, most properties including moisture content, water sorption and viscosity of both cassava- and corn-based maltodextrins were similar.

Cassava (Manihot esculenta Crantz) is an important food crop in many tropical countries in Africa, South America and Asia. However, in Thailand, this crop has been well recognized as more than a subsistence crop. It is important commercially as the raw material for a large and complex industrial system that has a significant impact to the country's economics. The roots of this crop contain high a starch content and approximately half of the total roots produced (20 million tons) are used for the starch industry. Cassava starch has many remarkable characteristics including high paste viscosity, high paste clarity and high freeze-thaw stability, which are advantageous to many industries. In particular, the native starch with high purity can be readily modified by physical, chemical and enzyme process to many diversified products to improve the starch functionality and, consequently, encourage more industrial application. This paper aims to describe the unique modification of cassava starch produced at the industrial level in Thailand with respect to technological aspect and product quality.
