| Abstract: | The moisture absorption curve of tea was fitted by using MATLAB software programming and least-square principle.The shelf life calculation of tea was studied,and the formula indicated the relationship between moisture content and storage time of tea was worked out.The results showed that the moisture content of tea in any stage of storage can be determined,so the quality of tea is always monitored. |
