摘要
[目的]研究重组鹅肝制品的品质评价方法及营养评价方法。[方法]以鹅肝为原料,复配鸡胸肉并添加木薯淀粉、大豆分离蛋白、谷氨酰胺转胺酶(TG酶)等辅料制备重组鹅肝。采用CRITIC-灰色关联法对不同配方重组鹅肝的色度、熟化损失及质构特性进行综合评分,筛选出最佳配方,考察其营养指标并对其进行营养评价。[结果]当鹅肝含量为15%、鸡胸肉含量为85%、TG酶含量为1.25%、木薯淀粉含量为10%、大豆分离蛋白含量为2.5%时,重组鹅肝的综合得分最高,为208.93分。重组鹅肝水分、蛋白质、脂肪含量分别为64.86,18.13,0.85 g/100 g;共检出14种脂肪酸,其中9种不饱和脂肪酸,5种饱和脂肪酸且含有亚油酸、α-亚麻酸和花生四烯酸,脂肪酸致动脉粥样硬化指数(AI值)和血栓形成指数(TI值)均<0.5;必需氨基酸总量/氨基酸总量(EAA/TAA)为43.25%,必需氨基酸总量/非必需氨基酸总量(EAA/NEAA)为76.22%,第一限制性氨基酸为蛋氨酸。[结论]通过CRITIC-灰色关联分析法对重组鹅肝的品质进行评价,可以反映重组鹅肝的品质特性。重组鹅肝属于高蛋白、低脂肪的食品,适合心脑血管疾病患者食用,其氨基酸组成合理,属于优质蛋白质。
[Objective]To analyse the quality evaluation methods for and nutrition evaluation of recombinant goose liver products.[Methods]Goose liver is used as the raw ingredient and combined with chicken breast,while tapioca starch,soybean protein isolate,and transglutaminase(TG)are added as auxiliary materials,to prepare recombinant goose livers.The CRITIC-grey correlation analysis is employed to comprehensively score the color,cooking loss,and texture characteristics of recombinant goose livers made with different formulas.Then,the best formula is screened for nutritional index observation and nutrition evaluation.[Results]The comprehensive score of recombinant goose livers is the highest at 208.93 with 15%goose livers,85%chicken breast,1.25%TG,10%tapioca starch,and 2.5%soybean protein isolate.The moisture,protein,and fat content of recombinant goose livers are 64.86,18.13,and 0.85 g/100 g,respectively.A total of 14 fatty acids are detected,including 9 unsaturated fatty acids and 5 saturated fatty acids,including linoleic acid,α-linolenic acid,and arachidonic acid.More importantly,the atherosclerosis index(AI)and thrombosis index(TI)are lower than 0.5.Additionally,essential amino acids/amino acids(EAA/TAA)and essential amino acids/nonessential amino acids(EAA/NEAA)are 43.25%and 76.22%,respectively,with methionine as the first limiting amino acid.[Conclusion]The quality of recombinant goose livers is evaluated using the CRITIC-grey correlation analysis,which can reflect the quality characteristics of recombinant goose livers.Recombinant goose liver is a high-protein,low-fat food suitable for patients with cardiovascular and cerebrovascular diseases.Reasonably in amino acid composition,recombinant goose liver is a source of high-quality protein。
