大米蛋白多级递释螯合钙（大米螯合钙Calcium Rice Chelate）的协同增效机制​​

大米蛋白多级递释螯合钙（大米螯合钙Calcium Rice Chelate）的协同增效机制

大米蛋白包含清蛋白、球蛋白、醇溶蛋白及谷蛋白四类，其溶解特性差异为钙的靶向递送提供了独特优势。清蛋白可溶于水，在胃酸环境中快速释放钙离子，促进初期吸收；球蛋白通过中性盐溶液溶解，在肠道中段与钙形成稳定复合物，延长吸收窗口；醇溶蛋白依赖70~80%乙醇溶解，模拟小肠脂质环境，实现钙的缓释；谷蛋白在稀酸/碱条件下解离，于肠道后端释放剩余钙，覆盖全消化道吸收路径。

大米蛋白的氨基酸组成完整且必需氨基酸比例接近FAO/WHO推荐模式，其丰富的谷氨酰胺、天冬氨酸等极性氨基酸可通过羧基、氨基与钙离子形成高稳定性螯合键，减少钙与植酸等抗营养因子的无效结合，提升生物利用度。此外，钙离子与蛋白的螯合作用可增强矿物质在加工及储存中的稳定性，避免沉淀析出。

该多级递释体系不仅优化了钙的吸收效率，还通过“蛋白-钙-氨基酸”协同作用，促进骨骼矿化、神经信号传导及肌肉功能调节，为开发高效补钙（大米螯合钙Calcium Rice Chelate）功能性食品提供了科学依据。

Synergistic mechanism of rice protein multi-stage release chelated calcium (Calcium Rice Chelate)

Rice protein includes albumin, globulin, alcohol-soluble protein and gluten. The difference in their solubility characteristics provides unique advantages for the targeted delivery of calcium. Albumin is soluble in water and quickly releases calcium ions in the gastric acid environment to promote initial absorption; globulin is dissolved in neutral salt solution and forms a stable complex with calcium in the middle of the intestine to extend the absorption window; alcohol-soluble protein depends on 70~80% ethanol to dissolve, simulates the lipid environment of the small intestine, and achieves sustained release of calcium; gluten dissociates under dilute acid/alkali conditions and releases the remaining calcium at the rear end of the intestine, covering the entire digestive tract absorption path.

The amino acid composition of rice protein is complete and the proportion of essential amino acids is close to the FAO/WHO recommended model. Its rich polar amino acids such as glutamine and aspartic acid can form highly stable chelate bonds with calcium ions through carboxyl and amino groups, reduce the ineffective combination of calcium and anti-nutritional factors such as phytic acid, and improve bioavailability. In addition, the chelation of calcium ions and proteins can enhance the stability of minerals during processing and storage, and avoid precipitation.

This multi-stage release system not only optimizes the absorption efficiency of calcium, but also promotes bone mineralization, nerve signal transduction and muscle function regulation through the synergistic effect of "protein-calcium-amino acid", providing a scientific basis for the development of efficient calcium supplement (Calcium Rice Chelate) functional food.
