采下的鲜叶送到茶厂去加工,“贮运”是必不可少的环节。贮运的方法直接关系着鲜叶的鲜度和质量,影响着成茶的品质。因此,采用科学的贮运方法是当前茶叶生产中值得重视的问题。 Gogiya(哥基亚)的测试报告指出,鲜叶过量盛装在容器中,叶温可升高到48℃左右,随着叶温的升高,鲜叶水浸出物含量减少。若不及时运往茶厂加工,鲜叶在容器内贮放一天,其干物质含量损失达5％左右。同时,鲜叶装运过程中的机械损伤和发热,会导致鲜叶红变,茶多酚、儿茶素等化学成分的减少,茶叶品质明显下降。为此,鲜叶采下后,要防止叶温升高,避免产生异味和劣变,就得将采下的
Take the fresh leaves sent to the tea factory to process, “storage and transportation” is an indispensable link. The method of storage and transportation is directly related to freshness and quality of fresh leaves, affecting the quality of tea. Therefore, adopting the scientific method of storage and transportation is a problem worth paying attention to in current tea production. Gogiya’s test report pointed out that when fresh leaves are stored in containers in excess, the leaf temperature can be raised to about 48 ° C, and the content of fresh leaf water extract decreases as the leaf temperature increases. If not shipped to tea factory processing, fresh leaves stored in containers for one day, the dry matter content loss of about 5%. At the same time, the mechanical damage and fever in the process of fresh leaf shipping will lead to the decrease of the chemical components such as fresh leaf red, tea polyphenol and catechin, and the tea quality will obviously decrease. To this end, fresh leaves after mining, to prevent the leaf temperature increase, to avoid odor and deterioration, you have to take the
