Preparation method of instant coconut protein powder

The invention provides a preparation method of instant coconut protein powder, and relates to the technical field of food. The instant coconut protein powder is prepared by mixing coconut protein powder dissolved by a phosphate buffer solution and a glucose solution prepared by the phosphate buffer solution, then adjusting the pH value to 9, then carrying out a water bath reaction, and carrying out pre-freeze-drying. The defects in the prior art are overcome, covalent cross-linking between protein and glucose is induced through heating of the coconut protein powder, the solubility of the coconut protein powder is remarkably improved, meanwhile, the morphological structure is changed, the hydrophilicity is remarkably improved, the dissolving time of the protein powder can be shortened, and the instant dissolving effect is achieved. 本发明提供一种速溶椰子蛋白粉的制备方法，涉及食品技术领域。所述速溶椰子蛋白粉通过将磷酸盐缓冲液溶解的椰子蛋白粉和磷酸盐缓冲液配置的葡萄糖溶液混合，再调节pH至9，后水浴反应，预冷冻干后制备得到。本发明克服了现有技术的不足，椰子蛋白粉通过加热诱导蛋白质和葡萄糖之间发生共价交联，显著提高椰子蛋白粉溶解性，同时改变形态结构，亲水性显著提高，可缩短蛋白粉溶解时间，达到
