Starch is an important constituent in many foods and plays an obvious role in achieving the desired viscosity in products such as sauces, pie illings, salad dressings, puddings, etc. Blending different starches has been reported to result in desirable functional properties which help to overcome some end-use limitations of native starches. Therefore, the purpose of this study was to determine t...
Starches were isolated from cassava, cocoyam and breadfruit by wet milling process. The physicochemical, functional and pasting characteristics of the isolated starches were then examined and compared. Moisture and fat contents varied between 4.91 – 12.94% and 0.90 – 2.20% respectively. Bulk density and pH ranged between 0.64 – 0.68 and 5.53 – 6.15, respectively. Cassava and breadfruit starches...
The properties and permeability of aroma compounds in food through the cassava starch films was investigated. Films were prepared by 5% starch and properties of the films were monitored at different concentration of two plasticizers; glycerol and sorbitol. Sorbitol-cassava starch films showed a better transmission rate (water vapor or/and oxygen), and had a higher mechanical properties; tensile...
Cassava is one of the most important root crops as a reliable source of food and carbohydrates. Carbohydrate metabolism and starch accumulation in cassava storage root is a cascade process that includes large amounts of proteins and cofactors. Here, comparative proteomics were conducted in cassava root at nine developmental stages. A total of 154 identified proteins were found to be differentia...
13 Cassava (Manihot esculenta Crantz), a key carbohydrate dietary source for millions of people in 14 Africa, faces severe yield loses due to two viral diseases: cassava brown streak disease (CBSD) 15 and cassava mosaic disease (CMD). The completion of the cassava genome sequence and the 16 whole genome marker profiling of clones from African breeding programs 17 (www.nextgencassava.org) provid...
The use of arbuscular mycorrhizal fungal (AMF) inoculation in sustainable agriculture is now widespread worldwide. Although the use of inoculants consisting of native AMF is highly recommended as an alternative to commercial ones, there is no strategy to allow the selection of efficient fungal species from natural communities. The objective of this study was (i) to select efficient native AMF s...
The cassava mealybug is a clear and present threat to the food security and livelihoods of some of the world's most impoverished citizens. Niche models, such as CLIMEX, are useful tools to indicate where and when such threats may extend, and can assist with planning for biosecurity and the management of pest invasions. They can also contribute to bioeconomic analyses that underpin the allocatio...
this study analyzed the effectiveness of cassava women processors in value addition technologies in abia state, nigeria. purposive and simple random sampling techniques were used to select ninety (90) women. data for the study were collected through a structured questionnaire and analyzed with descriptive statistics such as: frequency, mean scores and percentages and inferential statistics (tob...
Cassava polyploid breeding has drastically improved our knowledge on increasing root yield and its significant tolerance to stresses. In polyploid cassava plants, increases in DNA content highly affect cell volumes and anatomical structures. However, the mechanism of this effect is poorly understood. The purpose of the present study was to compare and validate the changes between cassava cultiv...
Neosilba perezi (romero & ruppel) is known as the cassava shoot fly or shoot fly, because, unlike other species of its genus, its larvae feed exclusively on shoots of cassava (Manihot esculenta crantz). these larvae kill the affected cassava shoots. natural parasitism by a braconid, phaenocarpa neosilba arouca & Penteado-Dias, 2006, on shoot fly larvae was studied at 3 locations in the southwes...
