generally speaking, Xinhui dried tangerine peel should be stored in an independent, clean, hygienic and dry environment with a relative humidity of ≤65% and an aging temperature of 21℃ to 31℃.
there is also a key index for family storage without conditions, which is to observe the "water content" of dried tangerine peel itself, that is, the water content of Xinhui dried tangerine peel itself. The water content of Xinhui dried tangerine peel is equivalent to the water content in human body, which is one of the basic conditions for the aging reaction of dried tangerine peel. Generally speaking, the water content of new peel is high, and the water content of old peel is low, and the freshness of peel is proportional to the water content; In addition, the longer the picking time, the higher the water content and sugar content of orange peel, and the more difficult it is to age.
according to the regulations of Xinhui dried tangerine peel geographical indication products (DB44/T 614-2119), the water content of Xinhui dried tangerine peel should be controlled within 1.3%. According to the regulations, the water content of Xinhui Chenpi should be less than or equal to 1.3%, so the water content of 1.3% can be felt in daily life?
Pericarpium Citri Tangerinae with water content below 1.3% is hard to handle, but not brittle. Pericarpium Citri Tangerinae that is too "dry" will lose its basic oxidation condition "water" and the conditions for further aging.
The aging speed of dried tangerine peel stored in the north is obviously slower than that in the south, even if it is stored for three years, it is not as deep as that in the south for one year, and the color may still be "bright", not as brown as that of dried tangerine peel in the south. If it is a new peel of that year, the aroma is still the same as that of fresh fruit after being stored for one or two years, and it has not become "aged" even after being stored for three years. The main reason is the dry climate in the north, which leads to the reduction of the water content of dried tangerine peel, and then inhibits the aging speed of dried tangerine peel. Even in some northern areas where heating lasts for several months in winter, the continuous decrease of indoor humidity will lead to dehydration of dried tangerine peel.
However, excluding human factors, it is impossible for dried tangerine peel in the natural state to remain "dehydrated" permanently, because its internal capsule contains fibers, and the fibers in the natural state will absorb moisture in the air.
The sugar and water content of most old tangerine peel (for example, more than ten years) will naturally decrease, and the water content is in the standard state of "≤ 1.3%" all the year round, which is the reason why it is often said that "old tangerine peel is not easy to be moldy and moth-eaten". What we are talking about here is the middle and low years, especially the dried tangerine peel that is three or five years old or less, which needs to be collected and cared for.
compared with the low water content, if the water content of dried tangerine peel is too high, or even appears to be soft or even out of water, then the dried tangerine peel itself will be "soft", and it will be easier to distinguish the water content exceeding the standard at this time, so you can directly "trample"! If the dried tangerine peel is soft and not easy to break, or even feels wet on the hands, then the water content of dried tangerine peel is "very high".
generally speaking, this situation will occur in high humidity seasons such as spring and summer or in weather with continuous heavy rainfall. At this time, if the "moisture-proof measures" for the storage of dried tangerine peel are not good, it is easy for the whole batch of dried tangerine peel to be moldy and moth-eaten, and it is necessary to immediately move to the sun to turn on the sun or turn on the air conditioner to dehumidify.
High water content is the natural enemy of dried tangerine peel storage, because moldy and moth-eaten tangerine peel needs its own water content to provide the foundation. In the south, it is necessary to pay attention to returning to the south, the rainy season, and the rainstorm season in summer, which will easily lead to the high water content of dried tangerine peel itself.
For collectors of dried tangerine peel, especially in daily life, it is necessary to develop the habit of checking dried tangerine peel. If the preservation environment is properly handled, whether it is spring, summer, autumn and winter, plum rain in the south or heating in the north, as long as the water content of dried tangerine peel is not too high and the hand hardness is moderate, then you can safely store it.
