Conclusions
Based
on the above results the following conclusion may be drawn: the relative
contribution of storage conditions studied to the retention of peanut
and soybean oils nutrition can be ordered as follows: underground
storage>added TBHQ storage>nitrogen storage>static atmosphere
storage. Underground storage was able to ensure comparable retention of
quality over 18 months of storage. Underground storage of peanut and
soybean oils can replace nitrogen storage and TBHQ storage. Results
obtained in this study confirmed that high temperature can cause a
significant decrease in the quality of peanuts and soybean oils,
especially combined with oxygen. Although adding TBHQ storage can
protect the flavor of peanut oil, its harmful compounds counteract its
positive effects. In contrast, nitrogen storage and underground storage
are greener and safer.
