一、工業淀粉的用途
工業級淀粉糊黏度比其他淀粉黏(nian)度變(bian)(bian)動小,因(yin)此常(chang)常(chang)被用于上(shang)漿劑(ji),粘接劑(ji)和各類食品類的(de)增稠(chou)劑(ji)。淀粉煮(zhu)冷卻,若濃度超出3.5%就行(xing)成軟的(de)凝膠,若濃度達標6%左右(you)便會(hui)變(bian)(bian)成彈性系數極大的(de)凝膠。
糖化原(yuan)(yuan)料:工業(ye)淀(dian)粉(fen)是糖膠、葡萄(tao)糖和(he)其他變性(xing)淀(dian)粉(fen)的原(yuan)(yuan)料。造(zao)紙:工業(ye)淀(dian)粉(fen)作上漿劑(ji)(ji)和(he)涂(tu)覆劑(ji)(ji),可增加紙的拉(la)力,改善表(biao)面強度與印刷適應性(xing)能。
二、工業淀粉和食用淀粉的區別
工(gong)業(ye)淀(dian)(dian)粉(fen)(fen)(fen)(fen)與食用(yong)(yong)淀(dian)(dian)粉(fen)(fen)(fen)(fen)的(de)不(bu)同(tong)是工(gong)業(ye)淀(dian)(dian)粉(fen)(fen)(fen)(fen)含(han)有(you)重金屬、有(you)毒物質(zhi)等雜質(zhi),且工(gong)業(ye)淀(dian)(dian)粉(fen)(fen)(fen)(fen)沒有(you)衛(wei)生(sheng)方(fang)面的(de)要(yao)求。第二工(gong)業(ye)淀(dian)(dian)粉(fen)(fen)(fen)(fen)與食用(yong)(yong)淀(dian)(dian)粉(fen)(fen)(fen)(fen)的(de)不(bu)同(tong)之(zhi)處還在(zai)于工(gong)業(ye)淀(dian)(dian)粉(fen)(fen)(fen)(fen)含(han)有(you)重金屬、有(you)毒物質(zhi)等雜質(zhi),且工(gong)業(ye)淀(dian)(dian)粉(fen)(fen)(fen)(fen)沒有(you)衛(wei)生(sheng)方(fang)面的(de)要(yao)求。而食用(yong)(yong)淀(dian)(dian)粉(fen)(fen)(fen)(fen)則在(zai)感官(guan)指(zhi)標(biao)(如色澤、氣味、口(kou)感、雜質(zhi))、理(li)化(hua)指(zhi)標(biao)和衛(wei)生(sheng)指(zhi)標(biao)(二氧化(hua)硫、鉛、砷(shen))上(shang)有(you)嚴格的(de)要(yao)求。
工(gong)業(ye)淀粉的危害(hai)性有(you)多(duo)大(da)?其實這個取決于里面有(you)毒有(you)害(hai)物(wu)質的含量,因此(ci)工(gong)業(ye)淀粉只能用于制作糨糊、造紙(zhi)和(he)涂料加工(gong)等,不能用于食品加工(gong),廣泛用于造紙(zhi)行業(ye)。
總結:食(shi)用淀粉(fen)(fen)主(zhu)要(yao)(yao)是(shi)添加(jia)(jia)到(dao)食(shi)材中(zhong),而工(gong)(gong)業淀粉(fen)(fen)是(shi)絕(jue)對不可(ke)以的(de),工(gong)(gong)業淀粉(fen)(fen)主(zhu)要(yao)(yao)是(shi)用來(lai)造(zao)紙等工(gong)(gong)業加(jia)(jia)工(gong)(gong),大(da)家可(ke)千萬(wan)不要(yao)(yao)弄混淆,這(zhe)可(ke)是(shi)關乎到(dao)咱們食(shi)品(pin)安全的(de)的(de)重要(yao)(yao)問題,大(da)家選購的(de)時(shi)候一定要(yao)(yao)擦亮眼睛,不要(yao)(yao)選錯了。
