Effects Of Moist Heat Treatment On Multi-Scale Structure And Digestion Properties Of Rice Starch With Different Amylose Contents
Exploring the effects of wet heat treatment on rice starch’s structure and digestibility, highlighting key findings and applications in food science.
This article uses in vitro simulation methods and modern analytical techniques to measure and examine the changes in the multi-scale structure and digestion performance of rice starch with different linear content after wet heat treatment, and clarifies the relationship between the multi-scale structure and digestion performance of rice starch after wet heat treatment. . The results show that the synergistic effect of heat energy and water molecules in the moist heat treatment system has a certain destructive effect on rice starch granules, reducing its average relative molecular weight, double helix content, relative crystallinity, and the formation of semi-crystalline lamellae. The degree of ordering decreases, the high molecular weight fragment area with Mw>2¡Á107 gradually broadens to Mw<1¡Á106, and the degree of damage of rice starch with lower amyloid content is more significant. On the other hand, moist heat treatment promotes the free movement of the degraded rice starch molecular chains, rearranges and orients the starch molecules, and forms a new single helix structure, which is beneficial to the improvement of the slow digestion and anti-digestion properties of rice starch, and the linear chain Rice with higher starch content has a more obvious increase in starch. The research results provide basic data and theoretical support for processed starch and starch-based nutritious and healthy foods.

Introduction to Rice Starch Research
Rice starch, a fundamental component of numerous nutritional and processed food products, has been the subject of extensive research due to its pivotal role in food science and technology. In a groundbreaking study conducted by Bian Huawei, an innovative approach employing in vitro simulation methods alongside contemporary analytical techniques was utilized to meticulously examine the changes in rice starch’s multi-scale structure and its digestion performance post-wet heat treatment. This research not only sheds light on the intrinsic properties of rice starch but also elucidates the nuanced relationship between its multi-scale structure and digestive performance following moist heat exposure.
Impact of Wet Heat Treatment on Rice Starch
The core of the study revolves around the assessment of how the synergistic interplay between heat energy and water molecules during moist heat treatment impacts rice starch granules. The findings are revelatory, indicating a pronounced destructive effect on the granules, evidenced by a decrease in average relative molecular weight, double helix content, and relative crystallinity. Furthermore, the research highlights a reduction in the orderliness of semi-crystalline lamellae, leading to a significant broadening of the high molecular weight fragment area from Mw>2×10^7 to Mw<1×10^6. Particularly noteworthy is the observation that rice starch with a lower amylopectin content undergoes more extensive damage, underlining the delicate balance inherent in its structural composition.
Adaptive Structural Transformations in Treated Starch
A pivotal aspect of the study is the identification of a silver lining to the moist heat treatment process. Despite the initial destructive effects, the treatment fosters the free movement of degraded rice starch molecular chains. This mobility facilitates the rearrangement and orientation of starch molecules, culminating in the formation of new single helix structures. Such structural reconfiguration is instrumental in enhancing the starch’s slow digestion and anti-digestive properties, marking a significant stride towards healthier food alternatives. It’s especially interesting to note that rice starch with a higher content of linear chains exhibited a more pronounced improvement in starch characteristics, pointing towards the potential for targeted modifications in starch composition to achieve desired nutritional outcomes.
Practical Implications and Future Applications
The implications of this research are manifold, extending beyond the confines of academic inquiry to practical applications in the realm of processed starch and starch-based nutritious foods. By providing a comprehensive understanding of the molecular and structural modifications induced by moist heat treatment, this study lays a solid foundation for the development of starch products with optimized digestibility and nutritional profiles. Furthermore, the insights gleaned from this research offer valuable guidance for the food industry in its pursuit of creating healthier, more sustainable food options.
Conclusion and Invitation for Further Inquiry
In conclusion, the meticulous investigation conducted by Bian Huawei represents a significant contribution to the field of food science, offering a deeper understanding of the complex interactions between the structural attributes of rice starch and its digestion performance post-wet heat treatment.
