lactic

lactic是英語形容詞，音標為/ˈlæk.tɪk/，意為“乳的；乳汁的”，與牛奶相關。其專業釋義涵蓋醫學、生物化學、食品工業等領域，常作為複合術語的前綴使用。

該詞通過詞根lact-（拉丁語“牛奶”）與後綴-ic構成，派生詞包括lactose（乳糖）、lactate（分泌乳汁）等。在套用場景中，lactic形成多種專業術語：生物化學領域涉及乳酸發酵（lactic fermentation）、乳酸脫氫酶（lactic dehydrogenase）等微生物代謝過程；醫學領域用於描述乳酸酸中毒（lactic acidosis）、血乳酸（Serum lactic）等體液指標；食品工業中則與乳酸菌（lactic acid bacteria）發酵技術相關，如傳統豆豉菌群分離、乳製品發酵等。

實驗室研究表明，乳酸菌可耐受pH1.0-3.0環境及1-3g/L膽鹽，其α-澱粉酶抑制率可達88.59%。離子交換樹脂技術可有效吸附發酵過程中的乳酸副產物，維持菌株活性。
