茶多酚对氧化引发剂诱导的休闲豆干品质劣化的保护作用研究
Study on protective effect of tea polyphenols on quality deterioration of leisure dried tofu induced by oxidative initiators
摘要
Abstract
In this study,leisure dried tofu(LD-tofu)was prepared with the marinade treated with tea polyphenols(TP)and oxida-tion initiators,and the effects of initiators on the quality of LD-tofu and the protective effects of TP were analyzed from the perspectives of nutritional composition,characteristic oxidation indicators,texture characteristics,intermolecular forces,and microstructure.Results showed that the protein and fat contents of LD-tofu in oxidation initiator group decreased to 15.05 g/100 g,11.06 g/100 g,respectively,during storage for 90 days,while the water content increased significantly to 56.23 g/100 g.Compared with the control group,the charac-teristic oxidation indexes and b* value of LD-tofu in the oxidation initiator group increased significantly with the storage time,and the tex-ture characteristics,L* value,and disulfide bond interaction force gradually decreased.The protein gel structure showed pore enlargement and structural fracture,indicating that the photoenzyme initiators easily induced the protein oxidation of LD-tofu,resulting in its quality degradation.TP(0.2％)could effectively prevent oxidation initiator induced changes in nutritional composition,color difference,texture characteristics,and other oxidative effects of LD-tofu by maintaining the protein gel network structure during 15-60 days,but the protec-tive effect was weak or not noticeable during 75-90 days.The research results can provide a theoretical basis for expanding the application of TP and quality safety control of LD-tofu.关键词
