柠檬酸

Apple peel was used as the major material in preparing a dietary fiber beverage. Based on the single factor and orthogonal experiments, the amounts of apple peel,citric acid, stabilizers,antioxidants and glucose were studied to give the optimal formula as follows: glucose 80g,citric acis 2g,apple peel 100g,Arabian gum 1.41g,CMC 0.70g and Vc 0.08g in 500ml water. At the same time, the stability of the beverage and the reservation of the colour, smell and taste were investigated.

以苹果皮为原料进行苹果皮膳食纤维饮料的研制，通过单因子试验和正交试验对饮料中苹果皮、柠檬酸、稳定剂、抗氧化剂、葡萄糖的用量进行探讨，得到了苹果皮膳食纤维饮料的最佳工艺配方为：每500ml水中添加葡萄糖80g、柠檬酸2g、苹果皮100g、阿拉伯胶1.41g、CMC 0.70g、VC 0.08g；同时还探讨了苹果皮膳食纤维饮料的稳定性以及色、香、味的保持问题。

Drink lemon juice: Lemon essentially contains good amounts of citric acid, which is a part of AHAs group that has amazing properties to reduce acne scars.

喝柠檬汁：柠檬其实含有大量的柠檬酸。柠檬酸是果酸的一种，其具有惊人的减轻疤痕作用。

Citrate synthase plays a key role in regulating TCA cycle and is responsible for catalysing the synthesis of citrate from oxaloacetate and acetyl CoA.

柠檬酸合成酶在TCA循环中起着关键的调节作用，它催化乙酰辅酶A与草酰乙酸缩合成柠檬酸。

A stream of wastewater from citric acid production process was treated by using a biological process of the following steps: wastewater from citric acid neutralization→cultivating feed yeast→solubles tank→photosynthetic bac-teria tank→activated sludge tank.

采用柠檬酸废水→培养饲料酵母→可溶化槽→光合细菌槽→活性污泥工艺流程处理柠檬酸废水，实验结果表明，技术可行：原废水中COD_和BOD_5的总去除率达98％以上，达国家GB8978-88排放标准；

Higher values indicate the addition of citric acid or other fruit juices.

柠檬酸含量高有可能是添加了柠檬酸或是其它果汁引起的。

Similarly, extrudate containing gum and citric acid exhibited increased solubility and swelling due to increased hydrolysis by citric acid which resulted in open structure that allowed rapid water penetration, swelling and solubility.

类似的，含有胶和柠檬酸的挤出物具有较好的溶胀性和溶解性也归因于柠檬酸的水作用，这种水解作用导致了结构的松散使水能很快渗透从而溶胀和溶解。

Iron oxide Nanocrystalline Powders were prepared respectively by precipitation, stearic acid gel, polyethylene glycol gel, citrate gel and iron citrate combustion. The influence of synthesis method on the final product, such as the crystal structure, crystalline grain size, dispersivity were studied.
