The antioxidative activities of a lotus seed epicarp extract in different concentrations (6.25, 12.5, 25, 50 and
100 μg.mL−1) in pork homogenates representative of Chinese Cantonese Sausage were evaluated using three
methods: thiobarbituric acid-reactive substances (TBARS) values, peroxide values (POVs) and acid values
(AVs). Also the cytotoxic and anti-obesity effects of the lotus seed epicarp extracts were evaluated using
an in vitro 3T3-L1 preadipocyte cell model. Results showed that the lotus seed epicarp extracts were
non-toxic and effective in inhibiting preadipocyte differentiation. Supplementation of pork homogenate
with lotus seed epicarp extracts was effective in retarding lipid oxidation. Moreover, the antioxidative and
preadipocyte differentiation inhibition effects of the lotus seed epicarp extracts were dose-dependent.
Thus, the lotus seed epicarp extract might be a good candidate as an antioxidant and anti-obesity natural additive
in Chinese Cantonese Sausage.
