Glucose and high fructose syrup (HFS) are made extensively from corn starch and the high cost of production demands the lookout for alternative starches as raw material. The present study was to compare the potential of tuber starches such as arrowroot, cassava, Curcuma, Dioscorea, sweet potato and Xanthosoma with corn starch for HFS production. The process consisted of liquefaction followed by...

BACKGROUND Short-chain fatty acids (SCFAs) have a role in maintaining bowel health and can assist in the prevention and treatment of colonic disease. The ability of acylated starches to deliver SCFAs to the large bowel has been shown in animal studies but has not been established in humans. OBJECTIVE The aim was to determine whether cooked, highly acylated starches were resistant to small int...

Environmental concerns about increasing industrial use of plastics and the associated waste are raising the demand for renewable sources to replace petroleum-based products, especially in the packaging sector. This thesis examined the relationship between molecular structures of starch and their material properties in coating materials for food packaging. Chemical modification of starch with ci...

Rice (Oryza sativa) endosperm is mainly occupied by homogeneous polygonal starch from inside to outside. However, morphologically different (heterogeneous) starches have been identified in some rice mutants. How these heterogeneous starches form remains unknown. A high-amylose rice line (TRS) generated through the antisense inhibition of starch branching synthase I (SBEI) and SBEIIb contains fo...

The disintegrant potential of native starches of five new cassava (Manihot esculenta Crantz.) varieties developed by the Crops Research Institute of Ghana (CRIG) was studied in paracetamol tablet formulations. The yield of the starches ranged from 8.0 to 26.7%. The starches were basic (pH: 8.1-9.9), with satisfactory moisture content (≤15%), swelling capacity (≥20%), ash values (<1%), flow prop...

Starch granules are an interesting stabilizer candidate for food-grade Pickering emulsions. The stabilizing capacity of seven different intact starch granules for making oil-in-water emulsions has been the topic of this screening study. The starches were from quinoa; rice; maize; waxy varieties of rice, maize, and barley; and high-amylose maize. The starches were studied in their native state, ...

The kinetics of amylose leaching in hot, excess water from native, oxidized-by-potassium permanganate and heat-treated potato starch at temperatures 62–90 °C was investigated isothermal conditions. For the first time, it proposed to describe kinetic data by Kroger–Ziegler equation. It found that for native range 62–70 °C, activation energy process is 192.3 kJ/mol, a temperature 80–90 decreases ...

Several physical and chemical treatments were employed to modify Taro (Colocasia esculenta) starch. Th e eff ects of pH and heating temperature on their swelling powers and solubilities were studied. At 95 oC, heat-moisture treated, oxidized and acetylated starches were more soluble, while cross-linked starch was less soluble as compared to raw starch. Heat-moisture treated and chemically modif...
