MOISTURE CONTENT ANALYSIS OF ORTHODOX BLACK TEA WITHERING PROCESS AT PT PERKEBUNAN NUSANTARA I REGIONAL 2 KEBUN CIATER SUBANG
Keywords:
Black tea, Fresh shoots, Moisture content, Orthodox system, Withered shootsAbstract
PT Perkebunan Nusantara I Regional 2 Ciater Garden is engaged in the black tea commodity using the orthodox system. In the production process, moisture content analysis is an important stage to control quality. Moisture content is the amount of water content that can affect the quality and stability of tea. This study aims to determine the results of the moisture content analysis of the orthodox black tea aging process, then determine the causal factors and impacts if there is a discrepancy in moisture content. The method used in analyzing the moisture content of orthodox black tea is the thermogravimetric method using the Halogen Moisture Analyzer. The test results at PT Perkebunan Nusantara I Regional 2 Ciater Garden showed that there were no deviations in the moisture content of fresh shoots and withered shoots of black tea. Success factors for tea testing include post-harvest management according to SOP, good weather, and appropriate raw materials. A mismatch in moisture content can be fatal. Too low moisture content results in fine tea powder and astringent taste, while too high moisture content results in uneven tea powder and bitter taste. Therefore, it is necessary to closely monitor the moisture content to ensure the quality of the tea produced.
