Stored in assorted parts of tea aging effects of

tea's gist amounts ​​embodied in the tea market in the amount of important weight. As the product identification of non-standard and immature market,Diesel Mens Jeans, the year of tea has transform difficult to nail a polemical issue. This publish, we invited to the South China Agricultural University, Professor Chen Wenpin for us in 2002, likened with the batch of tea samples, respectively, in Guangzhou, Shanghai, Kunming and Hong Kong after four years in different chapters of storage, sensory and physical and chemical quality changes differences.
1, Guangzhou, Shanghai, Kunming and Hong Kong, four places have different climatic conditions?
A: We tin discern from the blueprint under 4 places clear of the climate situation.

2, different climatic conditions, storage of tea, changing results?
A: No. We kind of tea, is A1 (Guangzhou-like), A2 (Shanghai-like), A3 (Kunming-like), A4 (Hong Kong example), storage of results the following table:
Number
Soup

Taste

A1 (Guangzhou)

Sweet Chen, plum aroma, thick
Chunnong more sweet
Ming green than yellow, soft A2 (Shanghai)
Bright orange

Yellow-green than the afterward, soft A4 (Hong Kong)

As can be seen from the chart

:
; (1) soup, and Kunming is still kind of storage of yellow-green tea, green tea and the soup is nearly regular drying, but the greatest change was in Shanghai tea-like orange-red tea.
(2) savor and aroma, too showed amazing differences in Kunming, the taste of tea samples stored more detached in like of non-fermented green tea, while the additional three tea samples have been apparent the post-fermented tea savor specifics.
This indicates that differ storage conditions, even as the same tea leaves, later the same aging dispose storage period, they change is a mammoth distinction.
This also proves storage time is only a tea aging factors, without thinking other storage conditions such as temperature,Cheap Diesel Jeans, humidity, storage time to judge just from the quality of tea is unscientific, it is complicated based solely on the sensory quality of tea leaves to resolve and validate the storage year.

3, four to tea aroma components of the difference is reflected in what areas?
A: The tea is a array of volatile aroma composition, aroma and how many content is resolute by the type of the terminal tea-like aroma. A absolute of 123 test detected volatile aroma components, which, A1 (Guangzhou) found 118 kinds of samples, A2 (Shanghai-like) only detected 95 kinds; A3 samples detected in 100 kinds of Kunming, A4 samples in Hong Kong only detected 92 kinds of volatile components. Instructions stored in different weather conditions, volatile aroma components of tea-like transformation of the results will be different.

4, the final learn results prove?
results show that: (1) storage conditions can significantly affect the aging changes of tea, tea relying solely on sensory difficult to identify the year.
(2) storage is temperature and humidity can be very significant shock on the quality of tea sensory and physical and chemical changes in the speed.
(3) conditions of storage is different, tea aroma and flavor composition changes significantly different, Chen Hong metaplasia is a technological foundation.
(4) that the storage of ripening tea aging is an important quality of the formation and processing processes, to accomplish modernization of tea aging process to enhance the development of tea industry, the merely direction.

5, for the special nature of tea, you have anybody counsel to consumers and businesses do?
A: Because of different temperature, humidity, geographical environment, the latter part of the aging of tea important, it is difficult based solely on the sensory quality of tea leaves to determine and verify the storage year. Today,Diesel Slim Jeans, the duration of 5 years, Chen has a large number of tea in the next few years, Chen ten years phase will gradually renowned tea market, so businesses and consumers, should have a definite knowledge of the identification of tea storage, in mandate to defend their rights.
suggested merchants:
(1) tea should not be also one-sided emphasis on the year, while ignoring the specific storage conditions and technical factors and the phenomenon of product quality, this is undoubtedly biased,Diesel Jeans Sale, are likely to reason chaos in the market, there's tea deceit on the year.
(2) the best in the business and clearly marked aboard the product certified at experts, the characteristic storeroom area, warehouse environment, arsenal temperature, storage moisture, storage annual, so namely buyers self-identification.
(3) Technically, appropriately increasing the storage temperature and humidity,Diesel UK, or select the suitable climatic conditions of the region to complete the role-based tea warehousing heat aging process, the abbreviate the ripening time, storage is to reduce costs, amend processing efficiency has a quite major significance.

also gives consumers two suggestions:
(1) tea is best for tea sweethearts warehousing environment, have some knowing and knowledge, know about the different climatic conditions, changes in way and progress of tea, accordingly making it simple to buy, the better to judge the merits of aging, and storage of authenticity.
(2) Tea storage is the same in different places, deserving to storage is the ambient temperature, humidity and other climatic conditions,Diesel Jeans, differences in the speed of transition products, aging and quality of the existence of extremely premonitory differences in storage is extremely significant conditions to determine the speed of aging changes. Therefore, consumers in the evaluation of the quality of tea, have to comesintoseffect the actual sensory tasting judge, not by the
