油脂煙點儀的實際應用“價值”
在zai我wo們men生sheng活huo中zhong，基ji本ben可ke以yi說shuo每mei天tian都dou要yao接jie觸chu到dao食shi用yong油you，它ta是shi美mei食shi製zhi作zuo的de最zui基ji本ben原yuan料liao，而er且qie高gao品pin質zhi的de食shi用yong油you營ying養yang價jia值zhi也ye很hen高gao，是shi人ren類lei的de必bi需xu品pin。如ru今jin市shi場chang上shang有you那na麼me多duo的de食shi用yong油you，各ge種zhong品pin牌pai的de，價jia格ge品pin質zhi都dou有you差cha異yi，我wo們men又you應ying該gai如ru何he鑒jian別bie它ta們men的de好hao壞huai呢ne？有you經jing驗yan人ren士shi會hui通tong過guo肉rou眼yan觀guan察cha其qi顏yan色se或huo是shi聽ting取qu他ta人ren的de意yi見jian。其qi實shi，在zai一yi些xie質zhi檢jian、科研、加工等單位都是借助於油脂煙點儀進行專業測定的。它的基本原理是：樣品被加熱後產生煙霧，當觀測到有少量、連續帶藍色的煙時，讀取溫度計指示的溫度，按加熱/鎖定鍵，儀表表頭的上部顯示數即為煙點，利用它就可以科學且有效的分辨食用油品質好壞。
以菜籽油為例，雖然市麵上很多的廠家都會生產菜籽油，但是由於生產菜籽油所采用的原料有差異、壓ya榨zha手shou法fa有you差cha異yi，精jing煉lian程cheng度du有you差cha異yi，因yin此ci實shi際ji上shang這zhe些xie菜cai籽zi油you的de成cheng分fen是shi不bu盡jin相xiang同tong，自zi然ran使shi用yong油you脂zhi煙yan點dian儀yi測ce定ding會hui發fa現xian它ta們men的de煙yan點dian值zhi也ye各ge不bu相xiang同tong，而er油you脂zhi的de煙yan點dian與yu食shi用yong油you的de品pin質zhi之zhi間jian存cun在zai著zhe密mi切qie的de關guan係xi，一yi般ban是shi煙yan點dian越yue高gao，品pin質zhi越yue好hao，因yin此ci通tong過guo測ce定ding煙yan點dian，可ke以yi分fen別bie食shi用yong油you品pin質zhi差cha異yi。下xia麵mian是shi目mu前qian常chang見jian的de一yi些xie食shi用yong油you的de煙yan點dian值zhi，以yi及ji它ta們men的de一yi些xie用yong途tu介jie紹shao：
