原生態(tài)DHA及新型風(fēng)味羊奶卡門(mén)貝爾奶酪加工與品質(zhì)評(píng)價(jià)
發(fā)布時(shí)間:2023-11-24 19:36
山羊乳及其產(chǎn)品因其獨(dú)特的口味、豐富的營(yíng)養(yǎng)以及被公認(rèn)為健康食品而越來(lái)越受到歡迎。然而,山羊乳及其產(chǎn)品中因短鏈脂肪酸含量高引起的特殊風(fēng)味,導(dǎo)致一些消費(fèi)者對(duì)山羊乳及其產(chǎn)品的接受度較低。此外,與牛乳相比,羊乳在某些國(guó)家的生產(chǎn)水平較低,并且缺乏相應(yīng)的研究和生產(chǎn)技術(shù),限制了山羊乳及其制品市場(chǎng)占有率。這可以通過(guò)增強(qiáng)其營(yíng)養(yǎng)價(jià)值及提高其感官特性的方法改善。在此背景下,本論文研究了飼喂補(bǔ)充微藻和改變干酪制作配方對(duì)山羊乳及其卡門(mén)培爾干酪的營(yíng)養(yǎng)和感官特性的影響。本研究通過(guò)在飼料中補(bǔ)充微藻粉提高羊奶中原生態(tài)DHA含量,將牛乳與羊乳混合以及應(yīng)用天然香料三種手段,以提高山羊乳卡門(mén)培爾干酪的營(yíng)養(yǎng)及風(fēng)味品質(zhì),開(kāi)發(fā)功能性和風(fēng)味獨(dú)特的新型卡門(mén)貝爾奶酪。通過(guò)飼喂在奶山羊的飼料中添加富含DHA的微藻粉,可以提高羊乳和卡門(mén)培爾干酪脂肪酸組成,而不會(huì)影響羊乳產(chǎn)量,化學(xué)成分和干酪的感官特性。飼料中補(bǔ)充微藻增加了羊乳及其干酪制品中二十二碳六烯酸(DHA)和總n-3脂肪酸的含量,而降低了總飽和脂肪酸含量和n-6/n-3脂肪酸的比例。在卡門(mén)培爾干酪生產(chǎn)過(guò)程中向山羊乳中添加牛乳會(huì)影響干酪的產(chǎn)量,理化性質(zhì)和脂肪酸分布。短鏈脂肪酸(癸酸;C6:...
