Abstract:

The effects of storage temperature, different sterlization treatments, different methods for adding Litsea cubeba
oil and light or darkness on microbiological indexes and vitamin C content of low-sugar orange peel-carrot complex jam
were investigated during storage. No addition of Litsea cubeba oil was used as a control. The results showed that different
sterilization treatments and light had only minor effect on the antibacterial activity of Litsea cubeba oil, but temperature and
different addition methods had a significant effect on its antibacterial activity. Additionally, all light, different sterilization
treatments, different addition methods and temperature had an evident effect on the antioxidant activity of Litsea cubeba oil.
Under the storage conditions established in this study, both the antibacterial and antioxidant activities of the complex jam with
the addition of Litsea cubeba oil were better than those of the blank group.

Key words: Litsea cubeba oil, jam, antibacterial activity, antioxidant activity
