1、大豆分離蛋白對(duì)調(diào)理重組牛肉品質(zhì)特性的影響 摘要:為探討大豆分離蛋白添加量對(duì)調(diào)理重組牛肉制品品質(zhì)特性的影響,以碎牛肉為實(shí)驗(yàn)原料,經(jīng)過調(diào)理和重組工藝,研究不同大豆分離蛋白添加量對(duì)產(chǎn)品的各項(xiàng)品質(zhì)特性的影響。結(jié)果表明:隨著大豆分離蛋白添加量的增加,調(diào)理重組牛肉制品的解凍損失顯著降低(P<0.05),出品率顯著提高(P<0.05),產(chǎn)品的質(zhì)構(gòu)特性得到顯著改善(P<0.05),黏結(jié)強(qiáng)度顯著增強(qiáng)(P<0.05),但是產(chǎn)品的色澤變暗(P<0.05)。另外,低場(chǎng)核磁檢測(cè)發(fā)現(xiàn),增加大豆分離蛋白的添加量,T2b和T21的弛豫時(shí)間均逐漸變短,而T22的弛豫時(shí)間逐漸延長(zhǎng),說明產(chǎn)品的保水性逐漸增
2、強(qiáng)。對(duì)產(chǎn)品進(jìn)行感官評(píng)價(jià)表明,大豆分離蛋白添加量為2.0%時(shí),產(chǎn)品品質(zhì)最好。綜合考慮產(chǎn)品品質(zhì)和感官質(zhì)量,確定在調(diào)理重組牛肉制品中大豆分離蛋白的最佳添加量為2.0%?! £P(guān)鍵詞:大豆分離蛋白;重組牛肉;品質(zhì)特性 Abstract:Thisstudyaimedtoevaluatetheeffectofsoybeanproteinisolate(SPI)additiononqualitycharacteristicsofready-to-eatrestructuredbeefproducts.Towardsthisgoal,restructuredbeefproductswe
