in this study, the effect of mentha piperita essence (mpe) incorporation into cassava films on the hydrophilic and physicochemical properties of the resulting biodegradable films was investigated. the properties included solubility, moisture uptake and contact angle. mpe was added into biodegradable films at different amounts (1, 2 and 3%, w/w total solid). all biofilms were plasticized with 40...

Three bulls (Zebu x Holstein) fitted with permanent cannuale in the rumen and in the duodenum were used to estimate the efficiency of microbial protein synthesis in the rumen, when the dietary carbohydrate consisted of different proportions of sugar (molasses) and starch (cassava root). Freshly chopped cassava forage was given each day as a source of roughage and protein . The flow of digesta t...

Eight Aspergillus niger strains which produced strong starch degrading amylase were isolated from the soil using a medium containing Remazol Brilliant Blue (RBB) starch as substrate. Amylase production was detected by the disappearance of the blue colour around the colony. Among the isolates, A. niger AM07 produced the largest clear zone (7.0mm) on Remazol Brilliant Blue (RBB) agar plate and al...

The importance of cassava has been realized as a high energy human food, animal feed and as an industrial raw material for sweeteners, ethanol and various other chemicals. Its industrial potential, however, has still not been tapped to any great extent. Broadening of the post-harvest utilization of cassava remains rather difficult due to several factors. The development of costand energy-effect...

Fortification of custard powder (CP) with protein from cheap sources such as soybean could potentially improve its nutritive value but may alter its functional and sensory properties. This study was therefore conducted to determine the effect of soy protein isolate (SPI) inclusion (0%-20%) on some functional and sensory properties of cassava starch-based CP. Functional, pasting, and sensory acc...

Cassava starch, typically, has resistant starch type 3 (RS3) content of 2.4%. This paper shows that the RS3 yields can be substantially enhanced by debranching cassava starch using pullulanase followed by high pressure or cyclic high-pressure annealing. RS3 yield of 41.3% was obtained when annealing was carried out at 400MPa/60°C for 15 min, whereas it took nearly 8h to obtain the same yield un...

Lactic acid is one of the functional and valuable compounds utilized in food, pharmaceutical, and chemical industries while Poly lactic acid (PLA) is a biodegradable polymer that has a variety of applications. In recent years, microbial conversion of renewable raw materials has become an important objective in industrial biotechnology. Among many raw materials available, tapioca starch is consi...

This work aims at examining the physical, chemical and functional properties of composite flour produced with cassava, rice, soybean flours, and potato starch and added with 0.5% xanthan gum. Nine blends of composite flours were prepared by homogenously mixing rice flour, cassava flour, soybean flour, and potato starch (RF:CF:SF:PS) in the proportions of 30:50:15:4.5, 30:45:20:4.5, 30:40:25:4.5...

Genetic diversity of cassava (Manihot esculenta Crantz), obtained by open or controlled pollination and selection, as well as from germplasm introductions from abroad, is being conserved, both in the field and in an in vitro gene bank. Nine hundred and eighty five germplasm accessions are being conserved under slow-growth conditions using an osmotic retardant medium. The major thrust given in t...

Currently the natural crude oil depletion has been brought into awareness. This affects many industries including petrochemical manufacturing. As a result, there are many attempts to develop novel processes to produce substitutes to such petrochemical products including plastics. Polylactic acid, made from polymerization of optically pure isomer of lactic acid, is one of such examples. In addit...
