Activated carbon filter material in the fermentation processing

Activated carbon is purified powder charcoal, through physical or chemical processing, produce microfracture, greatly increase its adsorption surface area, large specific surface area ( 500 ~ 1500 m2 / g) Effective adsorption and charge a wide range of compounds, phenolic compounds and their derivatives, in particular, small make up will go to the next is introduced in the activated carbon filter material after fermentation processing. Decolorizing carbon is often used to selectively remove flavonoids monomer and dimer, larger polymer is very difficult to penetrate the microporous activated carbon and deodorization in the aspect of odor removal of mercaptan carbon is very valuable, but also can remove the ideal flavor compounds. Activated carbon may also make the processed wine produces a typical odor. In addition, the activated carbon oxidation resistance, although this is likely to be valuable, but using a small wine sample test to avoid the bad, the influence of the accident is of vital importance, a typical dose from 2. Ranging from 5 to 50 g/hL. The use of activated carbon in edible oil has a long history, but their price is higher, retain more oil, and it is difficult to deal with, people are interested in a feature is that they can adsorption polycyclic aromatic hydrocarbons in coconut oil and fish oil.
