Different organogel formulations used as beef fat (BF) replacement (0%, 20%, 40%, 60%, and 80%) were utilized to optimize the mechanical properties of frankfurters. Organogels, made of canola oil (CO), included different concentrations of ethyl cellulose (EC) and sorbitan monostearate (SMS). They consisted of: 8% EC + 1.5% SMS referred to as organogel-I (OG-I), 8% EC + 3.0% SMS (OG-II), and 10% EC + 1.5% SMS (OG-III), which were found promising in a previous study when used at 100% replacement. Replacement of BF with organogels at all levels could bring down the very high hardness values (texture profile analysis and sensory) of frankfurters prepared using CO by itself, relative to the BF control. OG-I and OG-II quantity had no significant effect on hardness and springiness, being similar in many cases to the BF and lower than the CO control. Shear force values of all organogel treatments were not significantly different from one another, and were between the BF and CO controls. Smokehouse yield showed a pattern of decreasing losses with increasing organogel replacement level. Sensory analysis revealed that using CO by itself significantly increased hardness, but structuring the oil (via organogelation), brought it down to the BF control value in all OG-I and OG-II formulations. Juiciness was significantly reduced by using liquid oil but increased with raising the amount of organogels. Oiliness sensation increased with higher organogel substitution and was actually higher than the beef control. The study demonstrates the potential use of vegetable oil structuring in replacing the more saturated BF in emulsion-type meat products.
使用不同的有机凝胶配方作为牛肉脂肪(BF)替代品(0%、20%、40%、60%和80%)来优化法兰克福香肠的机械性能。由菜籽油(CO)制成的有机凝胶包含不同浓度的乙基纤维素(EC)和单硬脂酸山梨醇酯(SMS)。它们包括:8% EC + 1.5% SMS,称为有机凝胶-I(OG-I)、8% EC + 3.0% SMS(OG-II)和10% EC + 1.5% SMS(OG-III),在之前的研究中发现当以100%替代率使用时很有前景。相对于BF对照,在所有水平上用有机凝胶替代BF都可以降低仅使用CO制备的法兰克福香肠非常高的硬度值(质地剖面分析和感官分析)。OG-I和OG-II的用量对硬度和弹性没有显著影响,在许多情况下与BF相似且低于CO对照。所有有机凝胶处理的剪切力值彼此之间没有显著差异,且介于BF和CO对照之间。烟熏产量呈现出随着有机凝胶替代水平的增加损失减少的模式。感官分析表明,仅使用CO会显著增加硬度,但通过有机凝胶化构建油相,在所有OG-I和OG-II配方中可将其降低至BF对照值。使用液态油会显著降低多汁性,但随着有机凝胶用量的增加而增加。油腻感随着有机凝胶替代率的提高而增加,实际上高于牛肉对照。该研究证明了植物油结构化在替代乳化型肉制品中饱和度更高的BF方面的潜在用途。
