說起“脂肪”
，大家可能就會聯想到“肥胖”，導dao致zhi很hen多duo人ren都dou想xiang甩shuai掉diao它ta。其qi實shi不bu然ran，脂zhi肪fang是shi食shi品pin中zhong重zhong要yao的de營ying養yang成cheng分fen之zhi一yi
，能neng為wei人ren體ti提ti供gong必bi需xu的de脂zhi肪fang酸suan，也ye是shi人ren體ti熱re能neng的de主zhu要yao來lai源yuan。在zai食shi品pin加jia工gong過guo程cheng中zhong，原yuan料liao、半成品
、成品的脂類含量對產品的風味

、組織結構、品質
、外觀
、口kou感gan等deng因yin素su都dou有you著zhe直zhi接jie的de影ying響xiang，因yin此ci測ce定ding食shi品pin的de脂zhi肪fang含han量liang
，可ke以yi用yong來lai評ping價jia食shi品pin的de品pin質zhi，衡heng量liang食shi品pin的de營ying養yang價jia值zhi，也ye是shi對dui加jia工gong工gong藝yi進jin行xing監jian督du，對dui生sheng產chan過guo程cheng的de質zhi量liang進jin行xing管guan理li。其qi含han量liang可ke以yi利li用yong專zhuan業ye的de脂肪測定儀進行檢測。

    該儀器是根據索氏抽提原理、用yong重zhong量liang測ce定ding方fang法fa來lai測ce定ding脂zhi肪fang含han量liang，即ji在zai有you機ji溶rong劑ji下xia溶rong解jie脂zhi肪fang，用yong抽chou提ti法fa使shi脂zhi肪fang從cong溶rong劑ji中zhong分fen離li出chu來lai

，稱cheng量liang，計ji算suan出chu脂zhi肪fang含han量liang。本ben儀yi器qi主zhu要yao有you加jia熱re抽chou提ti，熔rong劑ji回hui收shou和he冷leng卻que三san大da部bu分fen組zu成cheng。操cao作zuo時shi可ke以yi根gen據ju試shi劑ji沸fei點dian和he環huan境jing溫wen度du不bu同tong而er調tiao節jie加jia熱re溫wen度du
，試shi樣yang在zai抽chou提ti過guo程cheng反fan複fu浸jin泡pao及ji抽chou提ti
，從cong而er達da到dao快kuai速su測ce定ding目mu的de。可ke用yong於yu檢jian測ce含han油you量liang在zai0.5%-60%範圍內的糧食、飼料、油料及各種脂肪製品。其特點是體積小巧、水浴加熱升溫快

、加熱均勻，儀器全部采用玻璃磨口接合，避免氣體泄漏問題
，減少溶劑蒸發損耗。采用數顯控溫
，控溫準，操作簡單方便。
