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)動小，因此(ci)常常被用于上漿劑，粘接(jie)劑和(he)各類食品(pin)類的(de)增稠劑。淀粉煮冷卻，若濃度超出(chu)3.5%就行成軟的(de)凝(ning)(ning)膠(jiao)，若濃度達標6%左右(you)便會變(bian)成彈性系數極大的(de)凝(ning)(ning)膠(jiao)。

糖化原(yuan)(yuan)料：工業淀(dian)粉是糖膠、葡萄糖和其他(ta)變性(xing)淀(dian)粉的原(yuan)(yuan)料。造紙(zhi)：工業淀(dian)粉作上漿劑(ji)和涂覆劑(ji)，可增加紙(zhi)的拉力，改善表面強(qiang)度與印刷(shua)適應性(xing)能。

二、工業淀粉和食用淀粉的區別

工(gong)業(ye)淀(dian)粉(fen)(fen)(fen)與(yu)食用淀(dian)粉(fen)(fen)(fen)的(de)不(bu)同(tong)是工(gong)業(ye)淀(dian)粉(fen)(fen)(fen)含(han)有(you)(you)重(zhong)(zhong)金(jin)屬、有(you)(you)毒(du)物質(zhi)等雜質(zhi)，且(qie)(qie)工(gong)業(ye)淀(dian)粉(fen)(fen)(fen)沒(mei)有(you)(you)衛生方面的(de)要(yao)(yao)求。第二工(gong)業(ye)淀(dian)粉(fen)(fen)(fen)與(yu)食用淀(dian)粉(fen)(fen)(fen)的(de)不(bu)同(tong)之處還在于工(gong)業(ye)淀(dian)粉(fen)(fen)(fen)含(han)有(you)(you)重(zhong)(zhong)金(jin)屬、有(you)(you)毒(du)物質(zhi)等雜質(zhi)，且(qie)(qie)工(gong)業(ye)淀(dian)粉(fen)(fen)(fen)沒(mei)有(you)(you)衛生方面的(de)要(yao)(yao)求。而(er)食用淀(dian)粉(fen)(fen)(fen)則在感官指(zhi)標(biao)（如色澤、氣(qi)味、口感、雜質(zhi)）、理化(hua)指(zhi)標(biao)和衛生指(zhi)標(biao)（二氧(yang)化(hua)硫、鉛(qian)、砷）上有(you)(you)嚴(yan)格的(de)要(yao)(yao)求。

工(gong)(gong)業(ye)淀粉的危害(hai)性有多(duo)大？其(qi)實這(zhe)個取決于(yu)里(li)面有毒有害(hai)物質的含量，因此工(gong)(gong)業(ye)淀粉只能(neng)用(yong)(yong)于(yu)制(zhi)作糨糊、造(zao)(zao)紙(zhi)和涂料加工(gong)(gong)等，不能(neng)用(yong)(yong)于(yu)食品加工(gong)(gong)，廣泛用(yong)(yong)于(yu)造(zao)(zao)紙(zhi)行業(ye)。

總結：食(shi)用(yong)淀粉主要(yao)(yao)是(shi)(shi)添加到食(shi)材中(zhong)，而工(gong)(gong)(gong)業(ye)淀粉是(shi)(shi)絕對不可以的，工(gong)(gong)(gong)業(ye)淀粉主要(yao)(yao)是(shi)(shi)用(yong)來造紙等工(gong)(gong)(gong)業(ye)加工(gong)(gong)(gong)，大(da)家可千萬不要(yao)(yao)弄混淆，這可是(shi)(shi)關乎(hu)到咱(zan)們(men)食(shi)品安全的的重要(yao)(yao)問題，大(da)家選購的時候(hou)一(yi)定要(yao)(yao)擦亮眼睛，不要(yao)(yao)選錯了。
