Summary: Starch is a complex carbohydrate polymer produced by plants and crops. It is essential for nutrition and energy in humans and animals. Nowadays, starch is commonly used in non-food industrial sectors. This review summarizes the structural properties of starch, analytical methods for starch characterization, and in planta starch modifications.

Summary: Granule size is a critical parameter affecting starch processing properties. Ultrasound treatments of different durations were applied on two starches with different granule sizes. The effects of ultrasound treatments on the structural and physicochemical properties of the starches were significantly different. Short-term ultrasonication increased the swelling power of the small granule starch, while long-term treatment caused changes in crystallinity and peak areas. The large granule starch showed a balance between amylose leaching and surface damages. The possible mechanism of the ultrasound effect was discussed.

Summary: The study found that the thickness of amorphous lamellae of starch was mainly correlated with the amount of amylose short and medium chains, while the degree of crystallinity was negatively correlated with the amount of amylose short and long chains. Interestingly, starch molecular size distributions were shown to have no correlations with the starch lamellar/crystalline structures.

Summary: Chlorella sp. MBFJNU-17, a strain rich in starch and protein, can be obtained by adjusting the glucose and urea content during cultivation. The structure and digestibility of the starch produced by MBFJNU-17 cells can be modulated by regulating the glucose and urea content in heterotrophic cultivation conditions.

Summary: This study focused on the mineral composition, morphology, thermal properties, and pasting profiles of isolated plantain starch. The starch is rich in K and exhibits various morphologies such as lenticular, elliptical, and semispherical shapes. The pasting profile is between a custard and a hydrogel, influenced by shear forces, van der Walls forces, and slurry morphology.

Summary: Swelling behavior involves the process of starch granules absorbing enough water to increase the viscosity of starch suspension under hydrothermal conditions, which is important in starch research. The changes in starch granules during the swelling process are crucial in predicting their functional properties in food processing. This article comprehensively reviews the mechanism of starch swelling, its influencing factors, and its relationship with the pasting, gelling, and digestion characteristics of starch.
