摘要:

采用真空气调包装和茶多酚、迷迭香等及其复合天然抗氧化剂对切块干腌火腿进行抗氧化处理,通过正交试验研究不同气氛条件、抗氧化剂及贮藏温度和时间对干腌火腿抗氧化的影响效果。结果表明:真空包装的过氧化值(POV)显著低于气调包装组(p < 0.01);迷迭香+VE 复合抗氧化效果最好(p < 0.01),含茶多酚的复合抗氧化剂对维持火腿肌肉的红度值具有显著效果(p < 0.05);酸价(AV)与贮藏温度呈正相关;AV、POV、TBARs 值随着贮藏时间的延长显著上升(p < 0.01),红度a* 值显著下降(p < 0.01),贮藏时间达到3 个月,包装切块火腿POV 超过国家限量指标(0.25g/100g);正交优化结果:采用0.05% 迷迭香+0.05% VE 喷淋切块火腿、真空包装、5℃贮藏2 个月;实验结果与感官评定具有良好的一致性。

Abstract:

The orthogonal test was design to study the effect of different packaging atmosphere conditions and natural antioxidants on lipid oxidation of dry-cured ham cuts. The result was shown that POV of vacuum-packed hams is significantly ower than that of modified atmosphere packed hams (p<0.01). Combination of rosemary with vitamin E (VE) shows the best effect of restraining lipid oxidation (p<0.01). The antioxidants containing tea polyphenols have good effect of keeping a* value of ham muscle highly (p<0.05). Acid value (AV) is positively correlated with temperature. AV, POV and TBARs values rise and a* value drops continually during storage (p<0.01). POV of all treatments exceeds the national value limit (0.25 g/100 g) after 3 months. The result of optimizing orthogonal test is as following: dry-cured ham cuts sprayed with 0.05% romemary extract and 0.05% VE, packaging with vacuum system, stored at 5 ℃for 2 months. It is well consistent with the result of sensory evaluation.
