Chemical fingerprint identification and control in the quality of tea on the application

Full and reliability, is a way to label the total properties of the map of tea products. Chemical fingerprint of tea is tea in order to fully reflect the chemical composition of the variety,[link widoczny dla zalogowanych], quantity and proportion, thus reflecting its quality. The chemical fingerprint of tea quality of tea as an indicator of evaluation criteria, to improve the standardization of enterprise level, reduce the sensory differences between batches of products. Because different regions in which the tea manufacturers, different climate, coupled with differences in the production process to produce the tea is not exactly the same style,[link widoczny dla zalogowanych], so its quality is not the same chemical fingerprint. According to tea quality standards can be the fingerprint of the theft counterfeit famous brands were identified, investigated and dealt with to protect the legitimate business interests of the River. 1 Haozhi Long et al: chemical fingerprint identification and control in the quality of tea on the application of regulation 63.5 .2 tea processing technology based on practice in a large number of the production process by identifying and testing the fingerprint obtained, should not be limited to the evaluation of final product quality and authenticity of discrimination, but also for the final product quality control, which regulate the production process. Associated with the tea quality during the process study,[link widoczny dla zalogowanych], emphasis should not be a component as an indicator to select the best technology, but rather on the active ingredient group, multi-index, to study the process can be repeated. The main active ingredient group index, consider a full range of tea production process, make tea from different areas can achieve the necessary requirements ��. Can use fingerprint similarity to evaluate the quality of tea; fingerprints of the various production processes changes, operating conditions investigated the degree of influence on product quality and its impact on the quality factor (or process) to determine the process parameters reasonable and important process cited. 5.3 First, tea blending process control of raw materials and blending tea to establish fingerprints. Tea raw fingerprint Competition in the number of peaks with less tea, but tea, some of the peaks of raw materials may be no tea blending, or Competition with a large proportion of tea, which characterize their sensory characteristics. Second is to establish goals tea samples fingerprints. Our goal kind of tea can be a high-quality finished tea, can also be a tea samples provided by customers, with its blending of work for the target tissue. Fingerprints of the target sample can be combined with materials like maps, according to the principle of what we lack of raw materials selected to form multiple sample; of the sample for analysis,[link widoczny dla zalogowanych], will be the map with the target-like patterns were compared to identify differences, and then combination, comparison, until the difference between these two spectra in our acceptable range. Of course,[link widoczny dla zalogowanych], the spectrum should be compared with the process of evaluation and review staff at the same time to confirm each other. If this proof fails, then the fingerprint does not fully reflect the various components of tea samples, further improvement of chromatographic analysis.
