This study utilized different plant-based composites to develop restructured meat-analog (MA). Physicochemical, thermal, mechanical, structural, and sensory properties of formulated MA as well as batter-coated fried MAs were studied, and compared with a commercial product. Protein (23.27-24.68 %), moisture (57.05-58.78 %), pH (7.19-7.57), color (L:64.76-66.84, a:0.62-1.98, b:18.84-20.49), and textural (MF:0.22-0.52 N, GF:0.07-0.24 N/sec, FA:0.74-1.92 N.sec) attributes of formulated MAs were substantially impacted by the ratio of soy-protein-isolate (SPI) and wheat-gluten (WG). Incorporation of higher WG and lower SPI resulted in the formation of chicken-like fibrous and porous structure, hence, increased consumers acceptability of MA-based coated fried products. Microporosity (crust:51.14-58.35 %, core: 63.57-71.55 %), surface opening (5.67-14.75 %), and fractal dimension (2.586-2.402) of coated fried MAs were dependent on the formulation of batter-coating. MA-based coated fried products surface moisture-fat (SMR:0.51-187.20 au; SFR: 2.01-20.17 au) profile significantly (p < 0.05) varied with the formulations of batter-coating. Negative glass-transition-temperature (around -23 °C) is prime concern for MA-based fried products stability at room environment.
本研究利用不同的植物基复合材料开发了重组肉类似物(MA)。研究了配方 MA 的理化特性、热学特性、力学特性、结构特性和感官特性,以及涂面糊油炸 MA,并与商业产品进行了比较。配方 MA 的蛋白质(23.27-24.68%)、水分(57.05-58.78%)、pH 值(7.19-7.57)、颜色(L:64.76-66.84,a:0.62-1.98,b:18.84-20.49)和质地(MF:0.22-0.52 N,GF:0.07-0.24 N/sec,FA:0.74-1.92 N.sec)特性受到大豆分离蛋白(SPI)和小麦面筋(WG)比例的显著影响。较高的 WG 和较低的 SPI 的加入形成了类似鸡肉的纤维状和多孔结构,从而提高了消费者对基于 MA 的涂层油炸产品的接受度。涂面糊油炸 MA 的微孔率(外壳:51.14-58.35%,芯部:63.57-71.55%)、表面开口率(5.67-14.75%)和分形维数(2.586-2.402)取决于面糊涂层的配方。基于 MA 的涂层油炸产品表面水分-脂肪(SMR:0.51-187.20 au;SFR:2.01-20.17 au)剖面随面糊涂层的配方显著变化(p < 0.05)。负玻璃化转变温度(约-23°C)是基于 MA 的油炸产品在室温环境下稳定性的主要关注点。
