Consumers demand new biologically natural-active ingredients with a great capacity to
promote a healthier advantage and free from toxicity. Pitcher (Nepenthes) is one of the
naturally carnivorous climber herbs. Extract from Nepenthes plant contains numerous
beneficial bioactivity characteristics. This research compared the impact of 0.05% pitcher
extract demonstrated with 10 ppm butylated hydroxyanisole on the accumulation of acid
value, peroxide value, carbonyl value and thiobarbituric acid during 12 months of storage.
Results showed that there was no significant difference between 0.05% pitcher extract and
10 ppm butylated hydroxyanisole in respect of acid value, peroxide value, carbonyl value
and thiobarbituric acid during preservation of the dried squid. Pitcher extract would be a
promising alternative to replace synthetic antioxidants to overcome oxidative rancidity in
the dried seafood.
