1、齊齊哈爾大學(xué)畢業(yè)設(shè)計(論文)摘要:果葡糖漿也稱高果糖漿(HighFructoseSyrup)或異構(gòu)糖漿,是以酶法糖化淀粉所得的糖化液經(jīng)葡萄糖異構(gòu)酶的異構(gòu)作用,將其中一部分葡萄糖異構(gòu)成果糖,由葡萄糖和果糖而組成的一種混合糖糖漿。果葡糖漿最大優(yōu)點在于含相當(dāng)?shù)臄?shù)量42%~90%的果糖,因而在甜味特性上與其他甜味劑共同使用,具有很好的協(xié)同增效作用,不僅可改善食品與飲料的口感,還可以減少苦味和怪味。果葡糖漿與蔗糖結(jié)合使用,可使其甜度增加20%~30%,而且甜味豐滿、風(fēng)味更好。果葡糖漿與甜蜜素、糖精等也有增效作用。果葡糖漿的主要成分和性質(zhì)接近
2、于天然果汁,具有水果清香,味覺甜度比蔗糖濃,且有清涼感。與蔗糖和甜菜糖比較,果葡糖漿具有溶解度高、易發(fā)酵、化學(xué)穩(wěn)定性和熱穩(wěn)定性好、滲透壓大、吸潮性和保濕性強(qiáng)等優(yōu)點。在飲料等食品生產(chǎn)中有取代蔗糖的趨勢,作為食品飲料基料的新型食糖果葡糖漿越來越被人們認(rèn)可和重視。本論文是設(shè)計年產(chǎn)100000噸果葡糖漿廠。以玉米淀粉為原料,本設(shè)計流程是采用雙酶法工藝,其流程為原料→液化→糖化→脫色→離交→蒸發(fā)→異構(gòu)→脫色→離交→蒸發(fā),制成固形物含量為74%的F-42型的果葡糖漿。本設(shè)計由四大部分構(gòu)成:設(shè)計說明書、工藝流程圖、重點設(shè)備裝配圖以及生產(chǎn)車間設(shè)備
