This study was carried out to investigate physicochemical properties, and antioxidant and antimicrobial activities of low-fat sausages (LFSs) covered with sodium alginate (SA) film alone and with powder film (TSA-film) formed by cross-linking cherry tomato powder (CTP) and SA with calcium chloride (CaCl2).
Sausages covered with the biodegradable film were assessed based on the measurement of pH, color (L*, a*, b*), proximate analysis, expressive moisture (EM), texture profile analysis, total plate counts (TPC), violet red bile, and 2-Thiobarbituric acid reactive substances (TBARS) during storage under refrigeration. LFSs wrapped with TSA-film were compared with those wrapped with SA-film and without film (control) during storage at 10°C for 35 days.
The LFSs covered with the mixed film had lower pH, lightness (L*), EM%, TBARS, and TPC, but lower yellowness (b*) and hardness values than those wrapped with TSA-film alone.
Lipid oxidation and microbial growth was retarded in sausages covered with biodegradable films, especially multiple films as compared to single film, thereby resulting in extended shelf-life of the LFSs.
本研究旨在调查单独覆盖海藻酸钠（SA）膜以及由樱桃番茄粉（CTP）和SA与氯化钙（CaCl2）交联形成的粉末膜（TSA膜）的低脂香肠（LFS）的理化性质、抗氧化和抗菌活性。
基于在冷藏储存期间对pH值、颜色（L*、a*、b*）、近似分析、表达水分（EM）、质地剖面分析、总平板计数（TPC）、紫红色胆汁和2-硫代巴比妥酸反应性物质（TBARS）的测量，对覆盖有可生物降解膜的香肠进行评估。将包裹TSA膜的LFS与包裹SA膜和未包裹膜（对照）的LFS在10°C下储存35天期间进行比较。
与仅包裹TSA膜的LFS相比，覆盖混合膜的LFS具有更低的pH值、亮度（L*）、EM%、TBARS和TPC，但黄度（b*）和硬度值更低。
与单膜相比，覆盖可生物降解膜（尤其是多层膜）的香肠中脂质氧化和微生物生长受到抑制，从而延长了LFS的保质期。
