張掖(ye)氫氧化鈣腐(fu)(fu)蝕性防(fang)護：其粉(fen)塵或懸浮液(ye)滴對粘膜有刺(ci)激(ji)作用(yong)，雖然(ran)(ran)程度上不如氫氧化鈉重，但也能(neng)引起(qi)噴嚏和(he)(he)咳(ke)嗽，和(he)(he)堿一樣能(neng)使脂(zhi)肪乳化，從皮(pi)膚吸(xi)收水分、溶解蛋白質(zhi)、刺(ci)激(ji)及腐(fu)(fu)蝕組織(zhi)。吸(xi)入(ru)(ru)石(shi)灰粉(fen)塵可(ke)能(neng)引起(qi)肺(fei)炎。容許(xu)濃度為5mg/m3。吸(xi)入(ru)(ru)粉(fen)塵時(shi)(shi)，可(ke)吸(xi)入(ru)(ru)水蒸氣、可(ke)待因及猶奧寧，在胸廓處涂芥末膏；當落入(ru)(ru)眼(yan)內時(shi)(shi)，可(ke)用(yong)流水盡快沖(chong)(chong)洗，再用(yong)5％氯化銨溶液(ye)或0.01％CaNa-EDTA溶液(ye)沖(chong)(chong)洗，然(ran)(ran)后將0.5％地(di)卡因溶液(ye)滴入(ru)(ru)。工(gong)作時(shi)(shi)應注意保(bao)護呼吸(xi)器官，穿(chuan)戴用(yong)防(fang)塵纖維制的工(gong)作服、手套、密閉防(fang)塵眼(yan)鏡，并(bing)涂含(han)油脂(zhi)的軟膏，以防(fang)止(zhi)粉(fen)塵吸(xi)入(ru)(ru)。

我(wo)國(guo)民間制作和使(shi)(shi)(shi)用(yong)(yong)魔(mo)(mo)(mo)芋(yu)(yu)(yu)凝(ning)(ning)膠(jiao)食(shi)(shi)品(pin)有2千年的(de)歷史，制作方法(fa)魔(mo)(mo)(mo)芋(yu)(yu)(yu)粉中(zhong)(zhong)(zhong)添加(jia)3050倍數量的(de)水，攪拌成糊(hu)狀，添加(jia)魔(mo)(mo)(mo)芋(yu)(yu)(yu)粉5％-7％的(de)張(zhang)(zhang)掖豫(yu)(yu)(yu)北(bei)鈣(gai)(gai)業氫(qing)氧(yang)化(hua)(hua)鈣(gai)(gai)經混合、凝(ning)(ning)固(gu)而(er)得。在(zai)魔(mo)(mo)(mo)芋(yu)(yu)(yu)凝(ning)(ning)膠(jiao)食(shi)(shi)品(pin)制作過程中(zhong)(zhong)(zhong)，行業中(zhong)(zhong)(zhong)慣例使(shi)(shi)(shi)用(yong)(yong)的(de)是張(zhang)(zhang)掖豫(yu)(yu)(yu)北(bei)鈣(gai)(gai)業氫(qing)氧(yang)化(hua)(hua)鈣(gai)(gai)，因為魔(mo)(mo)(mo)芋(yu)(yu)(yu)食(shi)(shi)品(pin)必(bi)須在(zai)堿(jian)中(zhong)(zhong)(zhong)才能凝(ning)(ning)固(gu)，同(tong)時使(shi)(shi)(shi)用(yong)(yong)張(zhang)(zhang)掖豫(yu)(yu)(yu)北(bei)鈣(gai)(gai)業氫(qing)氧(yang)化(hua)(hua)鈣(gai)(gai)制造出(chu)的(de)魔(mo)(mo)(mo)芋(yu)(yu)(yu)凝(ning)(ning)膠(jiao)食(shi)(shi)品(pin)，從凝(ning)(ning)膠(jiao)、口味、色澤和經濟(ji)性幾方面都優于(yu)其他堿(jian)，這(zhe)也(ye)是我(wo)國(guo)自古以來一直使(shi)(shi)(shi)用(yong)(yong)的(de)堿(jian)，且鈣(gai)(gai)離子還可以被人(ren)體(ti)(ti)吸(xi)收。另(ling)一方面，制成的(de)魔(mo)(mo)(mo)芋(yu)(yu)(yu)凝(ning)(ning)膠(jiao)食(shi)(shi)品(pin)又(you)必(bi)須浸泡在(zai)液體(ti)(ti)中(zhong)(zhong)(zhong)保(bao)存，因此張(zhang)(zhang)掖豫(yu)(yu)(yu)北(bei)鈣(gai)(gai)業氫(qing)氧(yang)化(hua)(hua)鈣(gai)(gai)又(you)起到酸度(du)調節劑(ji)的(de)作用(yong)(yong)。在(zai)日本，張(zhang)(zhang)掖豫(yu)(yu)(yu)北(bei)鈣(gai)(gai)業氫(qing)氧(yang)化(hua)(hua)鈣(gai)(gai)也(ye)是魔(mo)(mo)(mo)芋(yu)(yu)(yu)食(shi)(shi)品(pin)行業公認使(shi)(shi)(shi)用(yong)(yong)的(de)堿(jian)（酸度(du)調節劑(ji)）。
