Process Optimization and Quality Analysis of Sheep Milk Cake Using Dregea sinensis Hemsl.Coagulant
摘要
Abstract
This study aimed to investigate a novel technology for producing sheep milk cake using Dregea sinensis Hemsl.extract as a new coagulant.The processing conditions were optimized using one-factor-at-a-time and orthogonal array design methods.The sensory characteristics,physicochemical properties,color,texture characteristics and microstructure of the milk cake were evaluated in comparison with those of traditional acid-coagulated milk cake.The results showed that the optimal processing conditions,determined based on sensory score and yield,were as follows:curdling temperature 80℃,Dregea sinensis Hemsl.coagulant(DSHC)concentration 22.5%,calcium chloride concentration 0.015%,and pressing for 2 h at 3 kg/cm2.The sensory score of the milk cake prepared under the optimized conditions was 83.25±1.04,which was higher than that of acid-coagulated milk cake.The new milk cake contained(32.12±0.39)%protein,(20.45±0.25)%fat and(46.33±0.41)%moisture,and its calcium,phosphorus and selenium contents were significantly higher than those of acid-coagulated milk cake(P<0.05).Texture profile analysis indicated that the hardness,gumminess and chewiness were significantly better than those of the control group(P<0.05).The gel network of the DSHC milk cake was more homogeneous and had better water retention capacity.These findings indicate that the novel coagulant DSHC demonstrates potential to replace traditional acid-induced coagulation processes.The product had a uniform color,good taste and strong milky flavor.Therefore,this process can serve as a new technology for the production of sheep milk cake.关键词
