L-阿(a)拉(la)(la)伯(bo)(bo)糖(tang)(tang)(tang)，又稱樹膠(jiao)醛糖(tang)(tang)(tang)、果(guo)膠(jiao)糖(tang)(tang)(tang)；是一(yi)(yi)種戊醛糖(tang)(tang)(tang)。在自然界中L-阿(a)拉(la)(la)伯(bo)(bo)糖(tang)(tang)(tang)很少以(yi)單糖(tang)(tang)(tang)形式存在，通常與(yu)其(qi)他(ta)單糖(tang)(tang)(tang)結合，以(yi)雜(za)多(duo)糖(tang)(tang)(tang)的(de)形式存在于膠(jiao)質、半纖維 素(su)、果(guo)膠(jiao)酸、多(duo)糖(tang)(tang)(tang)及某(mou)些糖(tang)(tang)(tang)苷中。其(qi)對(dui)熱和酸的(de)穩(wen)定性高。L-阿(a)拉(la)(la)伯(bo)(bo)糖(tang)(tang)(tang)作為一(yi)(yi)種低熱量的(de)甜味劑, 健康食品 添加(jia)劑。L-阿(a)拉(la)(la)伯(bo)(bo)糖(tang)(tang)(tang)代表性的(de)生理作用是有選擇(ze)性地影響(xiang)小腸二(er)糖(tang)(tang)(tang)水解酶(mei)(mei)中消化蔗糖(tang)(tang)(tang)的(de)蔗糖(tang)(tang)(tang)酶(mei)(mei)，從而抑(yi)制蔗糖(tang)(tang)(tang)的(de)吸收。

L－阿(a)拉伯糖(tang)分(fen)子(zi)結構(gou)穩定，在(zai)高(gao)(gao)溫下不被(bei)分(fen)解(jie)，因此(ci)可以(yi)用于焙烤食品(pin)中(zhong)。軟(ruan)曲奇是(shi)一(yi)種美國人喜愛的(de)(de)(de)餅干，但是(shi)含糖(tang)量(liang)很高(gao)(gao)，容易造成肥胖，因此(ci)在(zai)此(ci)類餅干中(zhong)添(tian)加L-阿(a)拉伯糖(tang)能(neng)夠(gou)抑制(zhi)蔗糖(tang)的(de)(de)(de)吸收從而使人們減少對高(gao)(gao)糖(tang)餅干造成肥胖的(de)(de)(de)恐懼(ju)。同樣(yang)，在(zai)高(gao)(gao)熱量(liang)食品(pin)中(zhong)如蛋(dan)糕、蛋(dan)黃派等烘焙食品(pin)中(zhong)添(tian)加一(yi)定量(liang)的(de)(de)(de)L－阿(a)拉伯糖(tang)能(neng)夠(gou)降(jiang)低單位能(neng)量(liang)密(mi)度來吸引更多的(de)(de)(de)消費(fei)者(zhe)。

甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)是(shi)(shi)甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)劑分子刺激味(wei)(wei)(wei)(wei)蕾產生(sheng)(sheng)的(de)(de)一種復雜的(de)(de)物(wu)理(li)、化學和生(sheng)(sheng)理(li)過程。甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)的(de)(de)高低稱為(wei)甜(tian)(tian)(tian)(tian)(tian)度(du)(du)，是(shi)(shi)甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)劑的(de)(de)重要指標。甜(tian)(tian)(tian)(tian)(tian)度(du)(du)不(bu)能用物(wu)理(li)、化學的(de)(de)方(fang)法(fa)定(ding)量測(ce)定(ding)，只能憑借(jie)人們的(de)(de)味(wei)(wei)(wei)(wei)覺進行感官判(pan)斷。為(wei)比(bi)較(jiao)甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)劑的(de)(de)甜(tian)(tian)(tian)(tian)(tian)度(du)(du)，一般是(shi)(shi)選擇蔗(zhe)糖作(zuo)為(wei)標準(zhun)，其他甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)劑的(de)(de)甜(tian)(tian)(tian)(tian)(tian)度(du)(du)是(shi)(shi)與(yu)它比(bi)較(jiao)而得出的(de)(de)相(xiang)對(dui)甜(tian)(tian)(tian)(tian)(tian)度(du)(du)。測(ce)定(ding)相(xiang)對(dui)甜(tian)(tian)(tian)(tian)(tian)度(du)(du)有兩種方(fang)法(fa)：一種是(shi)(shi)將甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)劑配成可被感覺出甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)的(de)(de)低濃度(du)(du)，稱為(wei)極限濃度(du)(du)法(fa)；另一種是(shi)(shi)將甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)劑配成與(yu)蔗(zhe)糖濃度(du)(du)相(xiang)同的(de)(de)溶液(ye)，然(ran)后以蔗(zhe)糖溶液(ye)為(wei)標準(zhun)比(bi)較(jiao)該甜(tian)(tian)(tian)(tian)(tian)味(wei)(wei)(wei)(wei)劑的(de)(de)甜(tian)(tian)(tian)(tian)(tian)度(du)(du)，稱為(wei)相(xiang)對(dui)甜(tian)(tian)(tian)(tian)(tian)度(du)(du)法(fa)  。
