    摘要:

    對(duì)低溫?cái)D壓加酶脫胚玉米粉擠出物直接調(diào)漿糖化生產(chǎn)玉米糖漿進(jìn)行了試驗(yàn)。該技術(shù)省去了雙酶法生產(chǎn)玉米糖漿的淀粉生產(chǎn)和噴射液化工序和設(shè)備，以及對(duì)應(yīng)的水耗、電耗和環(huán)境污染。研究了擠出物的擠壓-液化系統(tǒng)參數(shù)對(duì)糖液的主要考察指標(biāo)的影響規(guī)律。實(shí)驗(yàn)室研究表明，加酶脫胚玉米粉擠出物糖化12h糖液的過(guò)濾速度、DE值和淀粉出品率分別為239.8～269.5L/（m2?h）、89.2%～89.3%和96.2%～97.2%。生產(chǎn)試驗(yàn)結(jié)果表明,添加耐高溫α淀粉酶的脫胚玉米擠出物，直接糖化17h和19h，糖漿的DE值分別為95.89%和95.10%,透光率分別為

    Abstract:

    98.5%和98.0%。Degermed corn grist with added enzyme extruded at low temperature was mashed and saccharified directly for production of corn syrup was carried out. Starch production and spraying liquescence procedure in traditional double enzyme method were omitted. Thereby the corresponding water consumption, electricity consumption and its environment pollution were all omitted. The influence regularity of parameters in extrusion-liquescence system to main indexes of syrup was analyzed. The laboratory experimental results indicated the filtration speed of syrup, the value of DE and the available ratio of starch in syrup for degermed corn extrudate with added enzyme when saccharified for 12h were 239.8～269.5L/(m2?h), 89.2%～89.3% and 96.2%～97.2%, respectively. The productive experimental results indicated the values of syrup DE of degermed corn extrudate with high temperature resistant α-amylase for 17h and 19h were 95.89% and 95.10%, respectively, the transparence percent of above syrup were 98.5% and 98.0%, respectively.
