Pyroligneous liquid has flourished human life in various fields for a long period as food additive for the sterilization, longer conservation and superoxidation of foods. It has been also a lot used to remove or reduce stench. Recently the use of pyroligneous liquid has been even varied, such as medication for atopic dermatitis and deodorizer of landfill. The liquid consists of mostly water and includes methanol and carbonyl that are not complied with the standards presented by Korea Food and Drug Administration (KFDA) for the use as a food additive. The design of this experiment has been focused on controlling acidity and amounts of methanol and carbonyl to use it as a food additive. The main purpose is to reduce the methanol because the amount of methanol in pyroligneous liquid used at this experiment exceeds its standard over 1400%. By mixing the pyroligneous liquid and water and distilling it, methanol is to be evaporated with water. After several experiments, it is confirmed that the proportion of pyroligenous liquid and water effects not only the amounts of methanol but also acidity and the amount of carbonyl. The primary purpose of this experiment is to optimize the proportion of mixed solution. |
