Cassava storage roots are an important staple food throughout the lowland humid tropics. However, cassava suffers from a poorly understood storage disorder, known as postharvest physiological deterioration (PPD), which constrains its exploitation. In an attempt to broaden the understanding of PPD, nine different cassava cultivars were analyzed for specific compounds accumulating during the proc...

Cassava starch is used extensively to produce isotropic, odorless, tasteless, colorless, non-toxic and biologically degradable films. The similarity in composition, mineral content, microscopic, thermal, physicochemical and rheological properties between cassava and cocoyam starches being reported in literature, it is expected that, cocoyam could be used to increase the supply in equivalent sta...

Dried cassava products are perceived as one of the potential sources of mycotoxin ingestion in human foods. Processing either contributes to the reduction of toxins or further exposes products to contamination by microorganisms that release metabolic toxins into the products. Thus, the prevalence of microbial metabolites in 373 processed cassava products was investigated in Nigeria. With the us...

We investigated the fungal entomopathogens Beauveria bassiana and Metarhizium anisopliae to determine if endophytic colonization could be achieved in cassava. An inoculation method based on drenching the soil around cassava stem cuttings using conidial suspensions resulted in endophytic colonization of cassava roots by both entomopathogens, though neither was found in the leaves or stems of the...

Cassava (Manihot esculenta, Crantz) is emerging as a dominant staple of primary or secondary importance in many developing countries of the humid and sub-humid tropics in Africa and elsewhere. Since it can withstand drought, it is sometimes a nutritionally strategic famine reserve crop in areas of unreliable rainfall. This paper reviews reasons for the spread of, and increasing interest in, cas...

Effects of addition of alum (0.00 -1.0% w/w) on pasting and some physicochemical characteristics of cassava starch were investigated with view to evaluate the potential of alum as a cassava starch modifying agent. The modified starch was prepared by pre-treatment of the native starch with alkaline at room temperature prior to modification using alum. Alum modified cassava starch were characteri...

Expansion of cropland in tropical countries is one of the principal causes of biodiversity loss, and threatens to undermine progress towards meeting the Aichi Biodiversity Targets. To understand this threat better, we analysed data on crop distribution and expansion in 128 tropical countries, assessed changes in area of the main crops and mapped overlaps between conservation priorities and cult...

a preliminary study on statistical modelling of a process for depolymerisation of cassava non-starch carbohydrate using halide salt assisted phosphoric and pyruvic acids were accomplished. the effects of three independent variables namely; acid concentration, potassium iodide salt and duration were studied using the central composite rotatable design on hydrolysis of the cassava non-starch carb...

Land suitability is the ability of a land for certain uses. The purpose this study was to soil salinity and potential cultivation food crops (cassava sweet potato) from two different locations in Yoom II Village, North Manokwari District. research method used observation with survey techniques. Parameters observed were physical properties (texture, structure, color, surface rock, effective dept...

Trehalose is a nonreducing α,α-1,1-disaccharide in a wide range of organisms, and has diverse biological functions that range from serving as an energy source to acting as a protective/signal sugar. However, significant amounts of trehalose have rarely been detected in higher plants, and the function of trehalose in the drought-tolerant crop cassava (Manihot esculenta Crantz) is unclear. We mea...
