Saline Water Salting and Drying Technology of Gastrodiae Rhizoma
Fresh tubers of Gastrodiae Rhizoma were harvested at the right time. A saline water salting and drying technology was developed for obtaining the medicinal materials of Gastrodiae Rhizoma in the place of origin and avoiding rot and mildew.
Method:
2
Fresh tubers of Gastrodiae Rhizoma were dug in Yiliang
Yunnan
Dejiang
Guizhou
and Chenggu
Shaanxi
the experiments of natural drying
and saline water salting and drying were carried out in the place of origin and Beijing. After the dirt was removed
the samples were tiled in a container immediately
added with varied proportions of saline water (0.03-0.10 g·mL
-1
NaCl in water)
hermetically pickled for 6-15 d. after being soaked and rinsed with water
the samples were put in a cool ventilated place or under sunshine to prepare dried medicinal materials of Gastrodiae Rhizoma. We described the appearance characteristics
measured the moisture content
gastrodin and nitrite. And the appearance was observed after storage in a simple warehouse for one year later.
Result:
2
Fresh tubers of Gastrodiae Rhizoma from three origins were naturally dried
the surface of gastrodia tubers became black
decayed and moldy
then we could not get dried medicinal materials. The appearance and the content of gastrodins in the medicinal materials of Gastrodiae Rhizoma processed by saline water salting and drying technology met the requirements for Gastrodiae Rhizoma in
the Pharmacopoeia of the People
'
s Republic of China
2015 and relevant standards of nitrite in salted food in
National Food Safety Standard Determination of Nitrite and Nitrate in Foods
Hygienic Standard for Preserved Vegetables
Green Food
-
Soybean Paste and Salted Vegetable
.
Conclusion:
2
The saline water salting and drying technology is developed to make medicinal materials of Gastrodiae Rhizoma quickly from fresh tubers of
Gastrodia elata
in the place of origin and Beijing. The metamorphism had not been observed after being stored in simple warehouses for one year. This technology can guarantee the quality of Gastrodiae Rhizoma
and provide a new method for the filed processing of Gastrodiae Rhizoma.
