含較少可溶性鈣、鎂化合物的水叫做軟水(softwater)。軟水不易與肥皂產(chǎn)生浮渣，而硬水相反。天然軟水一般指江水、河水、湖(淡水湖)水。經(jīng)軟化水處理的硬水指鈣鹽和鎂鹽含量降為1.～5毫克/升后得到的軟化水。雖然煮沸就可以將暫時(shí)硬水變?yōu)檐浰诠I(yè)上若采用此法來處理大量用水，則是極不經(jīng)濟(jì)的。經(jīng)過軟化水系統(tǒng)處理后的軟水可將肌膚細(xì)胞內(nèi)的污物清除，延緩皮膚衰老，使清洗后的皮膚無緊繃感，光澤細(xì)膩。

冷凍食品起步于2世紀(jì)7年代，經(jīng)過多年發(fā)展，改變了傳統(tǒng)的冷凍技術(shù)，使冷凍食品行業(yè)不斷完善，加快了冷凍食品行業(yè)的發(fā)展，現(xiàn)在冷凍食品行業(yè)花色品種多的是米面點(diǎn)心制品與預(yù)制菜肴，其中的冷凍蔬菜，大部分出口日本和美國。冷凍食品行業(yè)也存在不足，如交通運(yùn)輸業(yè)、冷凍食品行業(yè)沒有統(tǒng)一的行業(yè)標(biāo)準(zhǔn)和規(guī)范、國產(chǎn)速設(shè)備質(zhì)量不高等都影響冷凍食品行業(yè)的發(fā)展；其次是冷凍食品的菌落總數(shù)、大腸桿菌超標(biāo)問題時(shí)常發(fā)生，嚴(yán)重影響了冷凍食品的衛(wèi)生質(zhì)量。
