Abstract

Alginate-chitosan (Alg-CH) coated multiple water-in-oil-in-water (W/O/W) nanoemulsion loaded with sesamol and retinol was hypothesized to enhance the oxidative stability of margarine. Total phenol content (TPC), antioxidant activity, acid value (AV), peroxide value (PV), para-anisidine value (pAV), induction period (IP), and residual values of sesamol and retinol by HPLC were determined for 90 days. Margarine with tert-butylhydroquinone (TBHQ) (T3) had the higher TPC and antioxidant activity (8.05 mg gallic acid equivalent (GAE)/g), 53.1 %) than T1 (nanoemulsion, 7.39 mg GAE/g, 38.95 %), T2 (free-sesamol and -retinol, 6.98 mg GAE/g, 31.07 %), and T4 (no antioxidant, 6.46 mg GAE/g, and 14.45 %) while T1 had higher antioxidant activity and TPC than T2 and T4 after 90 days. On day 90, the highest residual values of sesamol (200.10 mg/100 g) and retinol (118.09 μg/100 g) obtained for T1. Overall, T1 contributed to the prolonged oxidative stability of margarine, potentially offering an alternative to synthetic antioxidants.

使用含有芝麻酚和视黄醇的海藻酸盐-壳聚糖包覆多重 W/O/W 纳米乳液改善人造奶油的保质期

海藻酸盐-壳聚糖（Alg-CH）包覆负载芝麻酚和视黄醇的多重水包油（W/O/W）纳米乳液被假定能提高人造奶油的氧化稳定性。采用高效液相色谱法测定了人造奶油 90 天的总酚含量（TPC）、抗氧化活性、酸值（AV）、过氧化值（PV）、对甲氧基苯胺值（pAV）、诱导期（IP）以及芝麻酚和视黄醇的残留值。含有叔丁基对苯二酚（TBHQ）的人造奶油（T3）的 TPC 和抗氧化活性（8.05 毫克没食子酸当量（GAE）/克，53.1 %）高于 T1（纳米乳液，7.39 毫克 GAE/克，38.95 %）、T2（游离芝麻酚和视黄醇，6.98 毫克 GAE/克，31.07 %）和 T4（无抗氧化剂，6.46 毫克 GAE/克，14.45 %），而 90 天后 T1 的抗氧化活性和 TPC 均高于 T2 和 T4。在第 90 天，T1 的芝麻酚（200.10 毫克/100 克）和视黄醇（118.09 微克/100 克）残留值最高。总之，T1 有助于延长人造奶油的氧化稳定性，有可能成为合成抗氧化剂的替代品。
