Description
Technical field
The invention belongs to grain and oil processing technique field, it is specifically related to the equipment that a kind of gac removes aflatoxin in peanut oil.
Background technology
Edible peanut oil contains abundant nutritive ingredient, very popular. But, peanut oil especially easily suffers the pollution of aflatoxin in production, transportation; And, along with the change of region weather type, the contaminated degree difference of peanut oil is very big, and particularly in the southern area of warming shed method, pollution condition is even more serious. Aflatoxin is the material that a kind of toxicity is extremely strong. The hazardness of aflatoxin is that people and animal livers tissue are had destruction, and liver cancer can be caused time serious even dead. In the food of natural contamination, the most common with aflatoxin B1, its toxicity and carinogenicity are also the strongest. At present, peanut and goods thereof have all been worked out the limitation value of harsh aflatoxin by developed country, and trend generally will be more and more stricter.
At present, the method removing aflatoxin in peanut oil mainly contains: biologic enzymolysis method, organic solvent extraction, ultraviolet irradiation and sorbent material method etc. But, there are some shortcomings in these prior aries: the processing efficiency of biologic enzymolysis method is low, and needs bigger cost; The first ether extraction that organic solvent extraction is developed such as Japan, though the low easy removal of the boiling point of organic solvent first ether, peanut oil has the residual of organic solvent; Ultraviolet irradiation effect is not remarkable.
