Comparative Analysis of Microstructure and Physicochemical Properties of Sweetpotato (Ipomoea batatas (L.) Lam) Starch
To explore and make use of the properties of sweetpotato starch (Luoshu), the particle morphology, particle size, ordered structure, lamella structure, amylose content, amylopectin chain length distribution, degree of branching, thermal, pasting and rheological properties of sweetpotato starch were analyzed. Furthermore, the correlations between their microstructure and physicochemical properties were also studied using correlation analysis. The starch granules were round spherical, round-like, oval, hemispherical, and angled polyhedral shapes, and the median diameter range was 15.01~18.40 μm. The pasting pattern of the sweetpotato starch was "from the central umbilical point of the starch granule to the surface", and the main fragments of amylopectin were short chains, with fa and fb1 chains accounting for 76.27%~79.22%. Luoshu 9 and Luoshu 10 had high peak viscosity and swelling power. Luoshu 11 had low breakdown value, high storage modulus and loss modulus. Luoshu 12 exhibited the lowest setback value and was difficult to retrogradation. Luoshu 14 had good thermal stability and elasticity. Luoshu 16 had the highest amylose content and setback value. Therefore, Luoshu 9 and Luoshu 10 could be used as thickeners, Luoshu 11 was suitable for baked foods, Luoshu 12 was suitable for frozen products, Luoshu 14 could be used as raw materials for jelly, and Luoshu 16 was suitable for starch noodle processing. In addition, particle size, molecular structure of amylose and amylopectin, short-range order degree were the key factors affecting the thermal stability, pasting and gel properties of sweetpotato starch. A significant correlation was observed between the microstructure and physicochemical properties of starch made from different varieties of sweetpotatoes, thus providing a basis for the processing and utilization of sweetpotato starch as well as sweetpotato breeding
Segmentation and lateral growth of intracratonic strike-slip faults in the northern Tarim Basin, NW China: influences on Ordovician fault-controlled carbonate reservoirs
Intracratonic strike-slip faults have been recognized as a major factor controlling the formation of fracture-cave carbonate reservoirs in deep buried basins, yet which properties and how the strike-slip faults influence reservoir distribution and their connectivity are still ambiguous. This uncertainty significantly restricts hydrocarbon exploration and development, such as in the Fuman oilfield, northern Tarim Basin, NW China. Using a high-resolution 3D seismic reflection survey and borehole data, we investigated the geometry and kinematic evolution of the FI17 fault zone in the Fuman oilfield. This fault zone is characterized by a single fault zone, pop-up or pull-apart structures, right-stepping en echelon normal faults, and much smaller displacement (<30 m) normal fault arrays from bottom to top. The FI17 fault zone consists of four genetic segments, including the extensional strike-slip duplex, Riedel left-lateral shear, right-stepping horsetail splay, and horizontal slip segments in map view. In particular, the formation of the ∼18 km Riedel shear zone is characterized by the growth and linkage of segmented shear faults (synthetic and secondary synthetic shears). We observed that the large-scale fault-controlled fracture-cave reservoirs are distributed in positions with wider fault zones, which are characterized by overlapping of neighboring secondary shear faults. Furthermore, the reservoir width examined in this study is natural logarithmic correlated (positively) to the fault zone width. The reservoirs linked by the same shear faults show better internal connectivity. The spatial coherence between fault geometry and reservoir features indicates that segmentation and lateral growth of intracratonic strike-slip faults controls the occurrence of fracture-cave reservoirs, which may provide support for reservoir prediction in the Fuman oilfield and other deeply buried fault-controlled carbonate reservoirs in general
