<p>In today’s fast-paced world, consumers gravitate toward products that offer quick preparation combined with high nutritional and sensory qualities. Rice, a staple food in many countries, particularly in Asia, serves as an excellent source of carbohydrates essential for energy sustenance. Its widespread consumption presents the food industry with ample opportunities to develop innovative rice-based products. Among these, instant rice has gained considerable popularity due to its convenience and rapid preparation. Nevertheless, the food industry faces several challenges in its production, including issues related to colour, flavour, texture, and long rehydration time. This review article explores advanced processing techniques and molecular insights into rice structure to improve the production of instant rice. It also provides an overview of various cutting-edge methodologies employed in instant rice processing, including innovations in pre-treatment, cooking, and post-cooking stages, highlighting their pivotal roles in the production process. Additionally, the study offers a systematic comparison of conventional and modern processing methods, assessing their respective impacts on rice quality and physical properties. Traditional processing techniques and their effects on texture and appearance are contrasted with modern methods designed to enhance the efficiency and quality. The respective advantages and disadvantages of these methods are carefully examined, providing a balanced perspective on their applications. Overall, this comprehensive study aims to present a detailed understanding of the relationship between advanced processing techniques and the molecular composition of rice, providing valuable insights for the production of high-quality, quick-preparation rice products.</p>
