1、看價格：一般(ban)來說，約2.5公(gong)(gong)斤花生(sheng)(sheng)(sheng)能(neng)榨出(chu)1公(gong)(gong)斤花生(sheng)(sheng)(sheng)油(you)和1.5公(gong)(gong)斤油(you)餅，生(sheng)(sheng)(sheng)產出(chu)1公(gong)(gong)斤花生(sheng)(sheng)(sheng)油(you)的最低成(cheng)本約14元。所以如果(guo)市場上賣的花生(sheng)(sheng)(sheng)油(you)價格低于(yu)最低成(cheng)本，那很有可(ke)能(neng)是(shi)小作坊生(sheng)(sheng)(sheng)產的劣質油(you)。

2、看感(gan)觀：新鮮(xian)花(hua)生(sheng)(sheng)(sheng)榨出來(lai)(lai)的花(hua)生(sheng)(sheng)(sheng)油色澤自然，金黃(huang)明亮，聞起(qi)來(lai)(lai)具有(you)花(hua)生(sheng)(sheng)(sheng)油的天然濃郁(yu)香味。若用霉爛或過了夏天的花(hua)生(sheng)(sheng)(sheng)仁榨出來(lai)(lai)的花(hua)生(sheng)(sheng)(sheng)油色澤深暗。

3、聞氣(qi)味(wei)(wei)(wei)：用右手指沾油(you)(you)少許，在左手心中(zhong)猛搓幾下，然后立(li)即(ji)嗅(xiu)其氣(qi)味(wei)(wei)(wei)，有濃郁(yu)純正花生(sheng)油(you)(you)香(xiang)、無異常味(wei)(wei)(wei)道的(de)，可(ke)認(ren)為是上品。而摻入香(xiang)精的(de)花生(sheng)油(you)(you)開(kai)始有微(wei)微(wei)的(de)花生(sheng)香(xiang)味(wei)(wei)(wei)，但(dan)是隨著再(zai)次揉搓，這種(zhong)花生(sheng)香(xiang)味(wei)(wei)(wei)會越(yue)來(lai)越(yue)淡。

4、看凝(ning)(ning)(ning)固(gu)溫(wen)度：花生(sheng)油(you)的凝(ning)(ning)(ning)固(gu)點為(wei)0-3攝(she)氏度，棕(zong)(zong)櫚油(you)為(wei)27-30攝(she)氏度，菜籽(zi)油(you)是零下(xia)12-零下(xia)10攝(she)氏度。將花生(sheng)油(you)放(fang)(fang)入冰箱冷藏室(shi)10分(fen)鐘(zhong)左右(you)，若(ruo)油(you)發(fa)生(sheng)凝(ning)(ning)(ning)固(gu)現(xian)象(xiang)，即(ji)(ji)可(ke)(ke)初步認定摻有(you)棕(zong)(zong)櫚油(you)；放(fang)(fang)入冰箱冷藏室(shi)約(yue)30分(fen)鐘(zhong)左右(you)，若(ruo)油(you)出現(xian)分(fen)層及凝(ning)(ning)(ning)固(gu)現(xian)象(xiang)，即(ji)(ji)可(ke)(ke)初步認定摻有(you)菜籽(zi)油(you)。
