A Review on Physicochemical and Thermorheological Properties of Sago Starch
This study was a part of a research project aiming to investigate the texture characteristics of protein starch interaction in fish based product keropok lekor. Accordingly, the current review study focused on some physicochemical (molecular weight, viscosity, chemical composition and swelling power) and thermorheological (gelatinization, retrogradation and viscoelsticity) characteristics of sa...
متن کاملOptimization of cyclodextrin production from sago starch.
Cyclodextrin (CD) is synthesized by bacterial cyclodextrin glycosyltransferase (CGTase) and is widely used in food, pharmaceutical, cosmetic, and agricultural industries. In this study, Bacillus circulans CGTase was partially purified by ammonium sulfate precipitation at 50-70% saturation. The optimum pH and temperature for CD production from sago starch were found to be in the ranges of 4.5-5....
متن کاملEffects of different temperature profiles and corn-sago starch ratios on physical properties of extruded tilapia diets
Sago starch is a locally grown and produced starch resource in Malaysia. In this study, corn starch to sago starch ratios (CS:SS) of 0:20, 5:15, 10:10, 15:5 and 20:0 were included in feed mixture to contain 20% starch and produce five isonitrogenous and isocaloric (30% crude protein and 16.7 kJ/g, respectively) tilapia Oreochromis sp. diets. Diets were preconditioned to contain 40% moisture and...
متن کاملEffects of phosphorylation and cross-linking on the pasting properties and molecular structure of sago starch
Native sago starch was phosphorylated with 5% sodium tripolyphosphate (STPP) or crosslinked with 4% phosphorous oxychloride (POCl3) at pH 8 to 11. The modified starches were characterized for degree of substitution (DS), pasting properties, crystallinity and molecular structure. The results indicated that DS of phosphorylated sago starch prepared at pH 9 was 0.008, which was the highest value a...
متن کاملEffect of Carboxymethyl Cellulose on the Mechanical and Barrier Properties of Sago Starch Based Films
Using biodegradable films is increasingly growing since they contain natural materials. In this study, sago starch and carboxymethyl Cellulose (CMC) were used in film preparation. Sago starch films with 0, 5, 10, 15 and 20% CMC concentrations were prepared using solvent casting method. The mechanical properties were determined according to standards of American Society for Testing and Materials...
