Unlocking potential: Rice protein’s diverse applications in edible films & peptides. Explore the rising demand in this nutritional powerhouse.

Rice protein, a collective term for the proteins found in rice, is typically present in by-products of rice processing. It primarily consists of four types of proteins: albumin, globulin, alcohol-soluble protein, and glutelin. In whole rice, the protein content is around 8%, with albumin accounting for 2%-5%, globulin 2%-10%, glutelin 66%-78%, and alcohol-soluble protein 1%-5%. In rice bran, the main proteins are embryo proteins, including 4%-9% albumin, 10%-11% salt-soluble globulin, 3% alcohol-soluble glutelin, and 66%-78% alkali-soluble glutelin.

Currently, rice protein is predominantly used in meal replacement products, animal feed, infant formula, energy bars, and similar applications. Its utilization in the development of functional peptides, edible films, and food additives is relatively limited. However, the diverse range and functional variety of small peptides produced by the enzymatic hydrolysis of rice protein, coupled with their easy absorption, present promising prospects in the field of functional peptide development. Additionally, the application of rice protein in the edible film sector aligns with the demand for high-quality and safe food products, offering a potential solution to environmental issues associated with non-renewable packaging materials.

According to the “2022-2026 Market Supply and Demand Status and Industry Operating Indicators Deep Investigation and Analysis Report on Rice Protein Powder Industry,” in 2021, China’s demand for rice protein powder was approximately 12,000 tons. Among the major demand regions, the highest demand for rice protein was in the East China region, accounting for 40% of China’s total demand, followed by the South China region with a 22% share. The demand for rice protein in North China, Central China, and the Western regions was relatively lower, accounting for 16%, 8%, and 7%, respectively.

As a product within the agro-processing industry, the sales channels are crucial for the development of rice protein enterprises. Particularly for export-oriented industries like rice protein, establishing an extensive domestic and international marketing network is essential to secure a larger market share. In the domestic market, rice protein production enterprises usually adopt a production model that combines “production based on sales” and “demand forecasting.” By predicting product sales based on historical data, these enterprises produce in advance and maintain appropriate inventory levels, minimizing the occurrence of severe oversupply or undersupply situations. With advancements in food technology, the industry recognizes the high nutritional value, low allergenicity, and multifunctionality of rice protein. Consequently, research and development in rice protein have become a new focus within the industry. As research in related fields progresses, the potential applications of rice protein in functional peptide development and the edible film sector are expected to be gradually unleashed. This, in turn, will drive the development of the rice protein demand market, indicating significant growth potential in the future.
