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.
