結(jié)論

葡萄酒無(wú)疑是一個(gè)非常復(fù)雜的分析矩陣。 其化學(xué)和儀器分析通常需要對(duì)樣品進(jìn)行預(yù)處理，以消除那些會(huì)干擾分析的化合物。 這種額外的程序既費(fèi)時(shí)又費(fèi)錢(qián)。 我們已經(jīng)通過(guò)統(tǒng)計(jì)分析表明，一些最重要的釀酒參數(shù)與表面張力顯著相關(guān)。 乙醇濃度已被證明是其中最好的負(fù)相關(guān)參數(shù)。 從 20 個(gè)葡萄酒樣品的分析中獲得的線性預(yù)測(cè)模型非常有效，因?yàn)樗梢越忉尭哌_(dá)近 91% 的乙醇含量變化。 通過(guò)包括 30 個(gè)以上的樣本來(lái)擴(kuò)展模型產(chǎn)生了令人滿意的結(jié)果。 提議的線性模型解釋了 81% 的乙醇含量變化，估計(jì)的標(biāo)準(zhǔn)誤差為 0.36% (v/v)，為釀酒師進(jìn)行常規(guī)分析提供了一個(gè)有趣的工具。 必須進(jìn)行更深入的研究，以便為蛋白質(zhì)和單寧等化合物建立可靠的類(lèi)似預(yù)測(cè)模型，否則需要費(fèi)力的方法來(lái)確定它們。
