COMMENTARY 
LITERATURE
analysis
-
investigation of molecular characteristics, microstructures, and physicochemical properties of modified starch gels prepared from partial enzyme treatments of the corn and rice starch pastes. Unlike the native and partially modified normal starches, the native and partially modified waxy starches can not form gels strong enough for textural analysis after 24 h for gel setting. The partially modified normal starches show specific apparent amylose contents and maximum iodine absorption wavelength, as well as the tri-modal molecular weight profiles and flatter side-chain distributions. The partially modified normal starch gels possess fractured surfaces with discontinuous crystalline fibrous assembly, which result in more brittle, rigid, and resilient gels compared with the native gels

food industry
-
the disproportionating enzyme 4alphaGTase, is used to modify the structural properties of rice starch to produce a suitable fat substitute in reduced-fat mayonnaise. The mayonnaise fat is partially substituted with the 4alphaGTase-treated starch paste at levels up to 50% in combination with xanthan gum. All mayonnaises exhibit shear thinning behavior and yield stress. Viscoelastic properties of mayonnaise are altered, and the mayonnaises exhibited weak gel-like properties. The magnitude of elastic and loss moduli is also affected by 4alphaGTase-treated starch concentration and presence of xanthan gum, microstructure, method, overview

synthesis
-
combination of maltogenic amylase reactions from Bacillus stearothermophilus and 4-alpha-glucanotransferase from Thermus scotoductus to increase the water solubility of puerarin, an isoflavonoid derived from Radix puerariae. The puerarin transfer products, including maltosyl-alpha-(1->6)-puerarin as a major product, are reacted with alpha-glucanotransferase in the presence of amylose. The maltosyl-alpha-(1->6)-puerarin-cycloamylose complex is formed by an elongation reaction and cyclization by alpha-glucanotransferase. The encapsulation of puerarin or glycosylated puerarin with a macrocyclic amylose is widely applicable both to improving the water solubility of the compound and stabilizing it during cold storage
synthesis
-
development of an efficient biocatalytic production process of cycloamyloses directly from sucrose by use of Synechocystis sp. 4-alpha-glucanotransferase and Neisseria polysaccharea amylosucrase. From one-pot synthesis, the maximum cycloamylose yield of 9.6%, w/w with 0.3 M sucrose is achieved with 10 units/ml of amylosucrase and 0.1 unit/ml of 4-alpha-glucanotransferase at 40°C for a 3 h reaction in a simultaneous dual enzyme reaction mode. The size of linear alpha-(1,4)-glucan is positively related to the cycloamylose productivity by 4-alpha-glucanotransferase in a hyperbolic manner. The dual enzyme reaction converts sucrose directly to cycloamyloses via in situ transient linear alpha-(1,4)-glucan as an soluble intermediate
