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.
采用 3 种方法评价了不同浓度（6.25、12.5、25、50 和 100μg/mL）的莲子种皮提取物在代表广东香肠的猪肉匀浆中的抗氧化活性：硫代巴比妥酸反应物（TBARS）值、过氧化物值（POV）和酸值（AV）。还使用体外 3T3-L1 前体脂肪细胞模型评价了莲子种皮提取物的细胞毒性和抗肥胖作用。结果表明，莲子种皮提取物无毒性，并能有效抑制前体脂肪细胞分化。向猪肉匀浆中添加莲子种皮提取物能有效抑制脂质氧化。此外，莲子种皮提取物的抗氧化和前体脂肪细胞分化抑制作用呈剂量依赖性。因此，莲子种皮提取物可能是广东香肠中一种良好的抗氧化剂和抗肥胖天然添加剂候选物。
