1、Supply Chain management供应链管理Product Acidity产品酸度Dear Colleagues:各位同事：CCCL has reported a number of Qasis Trade samples having low acidities. Acidity is a measure of assay which reflects the amount of beverage base in the product which is an important product parameter.可口可乐公司已经报告了一些Qasis市场样品被检测出酸度过低。酸
2、度是一种化验检测项目，它能反映产品中主剂的含量，而主剂的含量是产品的一个重要参数。Product acidity which measures the amount of FREE acid (which is titrible with alkali) and Product pH which measures the hydrogen ion concentration in the product should not be regarded as the same measure. NCB product which usually contains citric acid being
3、 a citric acid/citrate buffer system will have the product pH remains unchanged within appreciable dilution. The technical aspect of this subject will be covered in greater details at the forth coming Producer forum next week in Shanghai.产品酸度检测的是游离的酸的总量（通过碱液来滴定），产品pH检测的是 产品中氢离子浓度，两者不能认为是同一种检测。含有柠檬酸的
4、非碳酸饮料，可以看作是一个柠檬酸和柠檬酸盐的缓冲液，当它在被适当稀释的情况下，pH能够保持不变。关于这个内容的技术部分，在下星期即将到来的上海生产商研讨会上会有更加具体的细节告诉大家。What should be done is to set up proper SOP in all mfg locations to carryout Product Acidity measurement by batch which is a simple acid/base titration. Mike Wu has been asked to liaise with KM on this and to
5、 provide mfg locations with 需要做的是，在所有的生产厂里建立正确的SOP，对每批产品进行酸度检测，这个检测工作只是一个简单的对酸/主剂的滴定。我已经要求吴晓文和徐国民保持联络，提供给生产厂 - a) Test procedure测试程序b) Acidity Specification by product.产品酸度的标准The following factors affect acidity in the product以下的因素会影响产品中的酸度a) Incorrect Yield. Yield per unit is 2000 litre. If the pro
6、duct yield is not 2000 litre per unit - the acid concentration will change.不正确的收获率。每单位的收获率是2000升。如果产品的收获率不是每单位2000升 酸的浓度会发生变化。b) Incomplete transfer of beverage base into the product tank and/or unlikely but not impossible incorrect weight of beverage base supplied.没有完全将饮料主剂转移到产品混合缸中，并且/或者不太可能，但不是没有
7、可能，提供的饮料主剂本身重量就不正确。c) Acid neutralization by foreign alkali. If the product tank after CIP is not properly rinsed and contains residue alkali, it will neutralize the acid in the product. If the pipe work contains residue alkali which finally ended up in the product, it will neutralize the acid in th
8、e product.酸被“外来的”碱所中和。如果产品混合缸在CIP之后，没有被彻底的冲洗干净，还残留碱液，那这些碱液就会中和产品中的酸。如果管路中含有残留碱液，而这些碱液最终会被一起打入产品中，那也会中和产品中的酸。I would very much like each plant to do their own acidity measurement and to report any irregularities to SCMC/CCCL for immediate action. It is undesirable to be informed by CCCL that we have
9、low acidity Qasis sample without us having a mean to measure and monitor each batch we made at our plant (same for brix).我非常希望每个工厂能够进行酸度检测，并且将不正常的情况立即汇报给SCMC和可口可乐公司。可口可乐公司通知我们的Qasis样品酸度偏低，但我们却没有一个标准参数来进行检测和监控厂里生产的每批产品（就和Brix一样），这点是我们不希望看到的。Kindest Regards顺颂商祺Harvey Tong唐夏维2004-2-5中国上海市浦东金桥出口加工区桂桥路539号 邮编：201206 电话：（86 21）38984656 传真：（86 21）5032 1076No. 539 Gui Qiao Rd., Pu Dong Jin Qiao Export Process Area, Shanghai 201206, P.R.C.
