This work deals with the effect of the addition of inulin and bovine plasma proteins as fat replacers, on the quality of minced meat. The proteins are obtained by ultrafiltration and freeze-drying. The following determinations were carried out: chemical composition, sensorial analysis (color, flavor, taste and consistency), emulsion stability and instrumental texture analysis of samples. The resulting formulations were compared with full-fat minced meat, as control. The results showed an increase of protein contents after fat replacement, while a fat reduction of 20-35% produced light products enriched with proteins and inulin as the functional ingredient. No change was observed in color, flavor, or taste among the samples. However, the sensory analysis showed that the combination of plasma protein (2.5%w/w) and inulin (2%w/w) had the best acceptability with respect to consistency, and had a lower fat drain from the emulsion. Texture profile analysis revealed that this formulation assimilated the control texture properties, being that this result is required for adequate consumer acceptance.
这项工作研究了菊粉和牛血浆蛋白作为脂肪替代物对肉糜质量的影响。蛋白质通过超滤和冷冻干燥获得。进行了以下测定:化学成分、感官分析(颜色、风味、口感和质地)、乳液稳定性和样品的仪器质地分析。将得到的配方与全脂肉糜进行比较,作为对照。结果表明,脂肪替代后蛋白质含量增加,而脂肪减少 20-35%可生产富含蛋白质和菊粉的低脂产品,菊粉作为功能性成分。样品的颜色、风味或口感没有变化。然而,感官分析表明,血浆蛋白(2.5%w/w)和菊粉(2%w/w)的组合在一致性方面具有最佳的可接受性,并且从乳液中滤出的脂肪较少。质地分析表明,该配方与对照质地特性相似,这是获得消费者充分认可所必需的。
