Following the "toxic starch" incident, Taiwan's food crisis has once again expanded. Today, the puddings produced by well-known Taiwanese companies “unified†were exploded. The suppliers of Ligong Agri-products used industrial ethylene diamine tetraacetic acid disodium as food raw materials for six years and sold them to unification, resulting in seven products including almond tofu. The products were all discontinued on the platform. The Dongfangwang reporter found that the uniform puddings sold by the convenience stores in Shanghai did not come off the shelves, and the unification also stated that the mainland did not use any raw materials of Liguang, a Taiwanese pudding raw material supplier. Orient Internet reporters saw in the convenience store including the “Family†that the unified egg and mango puddings are still available. The place of production read “Suzhou, Jiangsu Provinceâ€.
According to media reports, Taiwan’s unified pudding was unloaded and exposed to industrial raw materials. Unified Enterprise (China) Investment Co., Ltd. issued a statement saying that the unified company did not use Taiwanese pudding raw material “Carrageenan†supplier Tainan City Guangnong Industry in the mainland. The company's raw materials. The pudding produced by the unified enterprise in the mainland is safe.
Plant extraction process
1. Select plants/medicinal materials. It is nothing more than ancient prescriptions, proven prescriptions, and folk medicinal herbs. At present, common and uncommon medicinal materials have been studied. Most of the time, the amount of medicinal materials has been increased to extract low-isolated components, or medicinal plants have not been studied from Miao medicine, Tibetan medicine, Mongolian medicine, Africa, Latin America and other places.
2. Extract. Solvent petroleum ether, n-hexane, cyclohexane, benzene, chloroform, ethyl acetate, n-butanol, acetone, ethanol, methanol, water (small polarity → large polarity). Daily decoction of medicines is effective, use water and ethanol and other solvents with high polarity. Artemisinin and other boiling methods are not effective, use petroleum ether and other solvents with low polarity. The common medicinal materials, water/alcohol/ether, are presented again, and more compounds can be separated and identified.
3. Separation. This is the most important task. There are dozens of compounds in the solution extracted in the second step. Generally, column chromatography is used, which is what we often call column flushing. The workload is large, boring, and low-tech. A master's degree may do this every day for 2 years of experimentation. As shown in the figure below, the column for separating compounds is as large as 2 meters high and as small as 10 cm. Change the solvent conditions of the mobile phase, change the material of the column, and repeatedly wash the column under different conditions and separation principles to separate the monomer compound.
