Abstract
|
|
|
Equal portions of Ganoderma lucidum which had been heated at 50℃ for 18 hours were extracted with small amount of ethanol, methanol and chloroform respectively.
The extracts were dissolved in the same amounts of an edible soybean oil and the resulting substrates and a portion of soybean oil(control) were placed in an incubator kept at 37.0 ± 1.0 ℃ for eight weeks. Peroxide values and TBA values of control and the substrates were determined regularly during the storage period. The results of the present study were as follows:
1. The moisture contents of Ganoderma lucidum at the time of sampling were 11.85% on wet basis and dried to 6.64% moisture content.
2. Extracts obtained from alcohols were effective in retarding the POV development.
3. There was not much difference among the TBA values after 14 days, but there was very significant difference between the TBA values of control and the substrates containing both ethanol and methanol extracts showed consistently smaller TBA values in the later stage period than the substrates containing chloroform.
4. In view of the POV and TBA value development, ethanol and methanol were effective solvents for the extraction of antioxidant compounds in the dried Ganoderma lucidum than chloroform.
