摘要

Chicken is an excellent source of protein and chicken products are consumed traditionally to improve health. After enzymatic hydrolysis, the ability of chicken protein hydrolysates to enhance exercise performance were evaluated through an experimental model by initiating a state of energy exhaustion with fasting. The hydrolysis process did not denotatively alter the total amino acids levels of protein samples. As hydrolysis time increased (1-5 h), large amounts of molecules in the water soluble protein hydrolysates (72.5- 88.1%) were found to have molecular weight below 1,000 Da. The consumption of hydrolyzed samples, especially hydrolysate II, would result in faster increase in blood glucose level. The peak blood glucose concentration of animals fed hydrolysate II could be attained 30 min earlier than the other protein samples. All protein samples were able to prolong swimming time by 45-134%, among which hydrolysate II was the most effective sample to generate energy and enhance swimming endurance, showing its potential in improving physical stamina and alleviating fatigue.

雞肉為蛋白質的重要來源之一。本研究將雞肉經過酵素水解後，利用誘使能量疲乏狀態的實驗模式，評估雞肉水解物在改善運動耐力與血糖供應之間的關係。雞肉樣品經水解後，樣品之間的總胺基酸含量無明顯變化，隨著水解時間延長（1-5小時），雞肉水解物之水溶性部分有多達72.5-88.1%的胜肽分子其分子量低於1,000 Da。動物攝食水解樣品後，尤其是水解物II，可幫助處於疲乏狀態的動物快速補充能量。在血糖供應方面，攝食水解物II上能比其他蛋白質樣品提前30分鐘到達高峰值。各蛋白質樣品能延長游泳時間約45-134%，其中水解物II的效果最為顯著，顯示具有改善精力和疲乏之潛力。
