The effect of the modified wheat gluten (MWG) extender, prepared by alcalase‐based hydrolysis and transglutaminase cross‐linking, on meatballs was analyzed in this study. Here, we studied the effect of MWG addition on the boiling resistance capacity of pork meatballs (MB‐MWG) at high temperature (100 °C) and increasing cooking time; meatballs with added soy protein isolates (MB‐SPI) and raw wheat gluten (MB‐WG) were used as references. The cooking loss, water‐holding capacity (WHC), and textural properties of meatballs were investigated. The results revealed that MB‐MWG showed lower cooking loss, which decreased by 49.16% compared to meatballs without added extenders when treated for 30 min. The WHC of MB‐MWG significantly increased from 80.68% to 95.42%. The hardness, springiness, and chewiness (textural properties) of MB‐MWG were also significantly increased by 97.05%, 6.68%, and 121.96%, respectively. The addition of MWG increased the cross‐linking in meatballs during the cooking process, as indicated by the higher G′. SDS‐PAGE indicated an obvious decrease in myosin heavy chain in MB‐MWG cooked for 30 min at 100 °C, which was attributed to the interaction of myofibrillar proteins in pork meat with MWG. The nuclear magnetic resonance T2 relaxation time patterns indicated that MWG addition caused an increase in the bound water content, and decrease in the free water content, of meatballs. An analysis of the microstructures revealed that the MB‐MWG formed the most regular and compact network. Therefore, MWG could be used as an ingredient to facilitate the processing of meat products. 相似文献

大豆组织蛋白丸子配方的优化研究 总被引:1,自引:0,他引:1
采用大豆组织蛋白为主料制作丸子,既能提高产品的营养价值,又能降低生产成本。通过单纯形格子法对大豆组织蛋白丸子配方进行研究分析,并利用质构仪来测定丸子的质地特征。结果表明:组织蛋白对丸子的弹性影响最大,大豆分离蛋白在咀嚼性、回复性和感官评定都起着重要作用。综合考虑成本与各因素指标,确定组织蛋白丸子配方为猪肉14.9%、大豆组织蛋白59.6%,大豆分离蛋白5%、变性淀粉13.4%、豆油7.1%,在该条件下制得丸子的弹性、咀嚼性、回复性和感官评定分别为0.921、1469.323、0.510和21.62,与预测值相对误差均在±1%以内,说明利用该方法建立的模型进行预测生产是可行的。 相似文献

In this study, sugar beet pectin and soy protein were used to prepare the double‐network (DN) modified‐tofu by sequential laccase and microbial transglutaminase treatments. The mechanical properties of modified‐tofu were analysed by uniaxial compression test and texture profile analysis. The DN modified‐tofu exhibited greater mechanical toughness than the corresponding single‐network modified‐tofu, while the ratio of soy glycinin to soy protein isolate reached and exceeded 50%. The enhancement of mechanical toughness may be mainly ascribed to the hierarchical microstructure which is observed in DN modified‐tofu by scanning electron microscopy. DN modified‐tofu provided a distinctive mechanical and sensory tough texture as compared to other tofu samples. In addition, the oral processing measurements indicated that DN modified‐tofu required higher jaw‐closing muscle activities, a greater number of chews and longer chewing duration to be processed. Furthermore, the chewing pattern of DN modified‐tofu was different from other tofu samples. 相似文献
