蘋果酸鈣（Calcium malate）對牛肉品質的影響

于肉中添加鈣鹽常被認為是一種化學嫩化方法，且部分鈣鹽具有良好的護色效果。無機鈣源主要使用碳酸鈣和磷酸鈣，部分使用氯化鈣。有機鈣源如甲酸鈣(Calcium Formate)、丙酸鈣(Calcium Propionate)、乳酸鈣(Calcium Lactate)、檸檬酸鈣(Calcium Citrate)、蘋果酸鈣(Calcium Malate)等，因其溶解度高、生物利用率高，作為新型飼料添加劑在反芻動物飼料中的使用越來越常見。有研究表明，甲酸鈣對肌肉和血液中鈣含量的提升優于氯化鈣，補充鈣對肌肉嫩度有一定的影響，添加1%的甲酸鈣，肌肉的嫩度最好。丙酸鈣被動物吸收后降解為丙酸和鈣離子，鈣離子作為一種礦物質參與機體各項代謝，丙酸是反芻動物生糖的主要原料，也作為體內脂肪主要合成的前體物質。檸檬酸鈣作為新型的有機飼料添加劑，其在機體可釋放出檸檬酸，檸檬酸可直接進入三羧酸循環通路被分解利用，最終為機體提供能量和鈣源。

Effect of calcium malate on beef quality

Adding calcium salts to meat is often considered as a chemical tenderizing method, and some calcium salts have good color protection effect. Inorganic calcium sources mainly use calcium carbonate and calcium phosphate, and some use calcium chloride. Organic calcium sources such as calcium formate, calcium propionate, calcium lactate, calcium citrate, calcium malate, etc. are more and more commonly used as new feed additives in ruminant feed because of their high solubility and high bioavailability. Studies have shown that calcium formate on muscle and blood calcium content is better than calcium chloride, calcium supplementation has a certain impact on muscle tenderness, adding 1% calcium formate, muscle tenderness is the best. Calcium propionate is absorbed by animals and degraded into propionic acid and calcium ions. Calcium ions participate in various metabolism of the body as a mineral. Propionic acid is the main raw material for sugar production in ruminants, and also serves as the main precursor for fat synthesis in the body. As a new organic feed additive, calcium citrate can release citric acid in the body, and citric acid can directly enter the tricarboxylic acid cycle to be decomposed and utilized, and finally provide energy and calcium source for the body.
