酸味剂:是以赋予食品酸味为主要目的的食品添加剂,给人爽快的感觉,可增进食欲.一般具有防腐效用,又有助于溶解纤维素及钙、磷等物质,帮助消化,增加营养.
  酸味剂分为有机酸和无机酸.食品中天然存在的酸主要是有机酸,如柠檬酸、酒石酸、苹果酸和乳酸等.目前作为酸味剂使用的主要也是这些有机酸.最近用发酵法或人工合成制取的延胡索酸(富马酸)、琥珀酸和葡萄糖酸-δ-内酯等也广泛用于食品调味.无机酸主要是磷酸,一般认为其风味不如有机酸好,应用较少.
  酸味具有增进食欲,促进消化、吸收的作用,并给人以清凉、爽快的感觉.酸味剂的酸味一般是氢离子的性质.但是,酸味的强弱并不能单用pH表示.不同的酸有不同的酸味感.这与其pH、酸根种类、可滴定酸度、缓冲作用和其他物质特别是糖的存在有关.
  柠檬酸是酸味剂中最温和、可口的酸味剂,在食品工业中应用最广,需要量也最大.苹果酸、乳酸等酸味剂的应用也在发展中.

这个广告通过与传统普洱茶饮品进行对比来表现本产品现在年轻人对茶饮料的两个要求:1.携带方便2.饮用方便.在镜头中出现了两种普洱茶,传统普洱茶因为需要冲泡,温度高,不易携带,饮用不方便.而在旁边的新型瓶装的普洱茶,不需要现场冲泡,不仅方便携带,而且饮用方便快捷.新型普洱茶抓住现代年轻人生活节奏快,压力大等特点,推出方便饮用的普洱茶.

公司
通过调查对市场经行分析,重新定位企业的形象以及针对的消费人群.
注重茶饮料的原料来源的安全性和质量,并且通过升级改造原有的制茶工艺以及机械设备来达到更符合年轻人对于茶饮料的口感的要求.
加大对于茶饮料在年轻人范围内的宣传力度,争取让每一个年轻人知道并且了解普洱茶的功效以及改良后对于年轻人偏爱的贴合.
产品
针对年轻人在现阶段的***地位以及喜好做出不同种类的茶饮料.通过调查找到不同青年人对于茶饮料的喜好偏向,经过研究对茶饮料的成分的不同经行分层.比如:白领阶层因为平常生活压力大,饮食不规律而引起的各种肠胃疾病以及因为长时间因过度劳累而导致的身体体内营养失衡和身体亚健康等问题,我们可以推出保健类的普洱茶饮料,把宣传的重点放在普洱茶对于身体健康以及调理体质的作用上.并且通过广告的投放使现在年轻人认识到,普洱茶不仅仅是一种中老年人才会去饮用的茶饮料,对于年轻人同样是一种很好的产品选择.
市场
在***市场中,普洱茶的主要销售对象是中老年人因为此类人群对健康以及生活品质有着很高的要求而普洱茶可以满足这一要求.而在***主要的普洱茶广告也是针对中老年人设计的,包括形式,载体,画面构图,寓意以及主题,凸显自己产品对于健康养身和品味的设计.但是在当前***,主要购买力来自于20-30岁的青中年人,因为工作的原因使青年人更容易劳累以及产生身体的亚健康状态,所以***的普洱茶公司对于这个市场的开发还处在起步阶段,并没有发现这个很大的市场并且推出广告以及产品.所以我希望通过针对年轻人的市场的开发以及研究,发展达到开创一种新的年轻人可以引用的普洱茶饮料的目的.
宣传
在宣传方面要注重对于普洱茶的传统文化与现代文明相结合的方面,通过各种传媒载体来宣扬茶饮料在现代人生活中的重要性.在载体选择方面着重于网络,电视和各种活动的传媒方式.因为现代的年轻人的生活方式更娱乐化、网络化,所以对于网络广告和电视广告以及活动赞助、冠名等年轻人参与感强的载体方式上的广告投放一定要重视.并且广告的方式以及形势也要跟传统型的普洱茶广告有所区别,要针对年轻人这个市场通过年轻人的视角来诠释全新的普洱茶饮料,主题明快,动感十足.广告方式可以是互动性的,平面的,或是电影形势的.

But in the current society, the main purchasing power from 20-30 years old QingZhongNian people, because the reason that young people more easily fatigue and produce the body and health status, so that the Chinese tea for the market development company is still at the beginning, and have not found the big market and launched advertising as well as products. So I hope that through for young people of the market development and research, development to create a new kind of young people can quote of puer tea beverage purposes.
