富含锌的食物包括牡蛎、烤豆、酸奶、蟹肉、牛腱肉、猪肩肉、菠菜、坚果以及全部的谷物。

Some foods that can help to add zinc to the person 's diet are oysters , baked beans , yogurt , crab , beef shanks , pork shoulder , spinach , nuts and whole grains .

首先，采用胰酶消化和酸抽提相结合的方法提取了牛腱胶原，通过紫外-可见光谱、傅立叶变换红外光谱以及氨基酸分析表征了牛腱胶原的组成和结构。

Firstly , the collagen was obtained by the trypsin digestion and acid extraction from bovine tendon . Its purity and structure were characterized by Uv-Vis absorbance spectroscopy , Fourier transform infrared spectroscopy and amino acid analysis .

结果表明：在两种加热方法中，随着加热终点温度的升高，牛半腱肌肉蒸煮损失和剪切力值增加（P0.05）。

The results showed that cooking loss and WBSF value increased with increasing in heating temperature for both water-bath and microwave heating ( P0.05 ) .

研究结果表明：超声处理对肉蒸煮损失无显著影响，牛半腱肌肉剪切力值降低（P0.05）。

The results indicated that using ultrasonic processing reduced WBSF values of meat ( P0.05 ) . However , sonication had no significant effect on cooking loss .
