不同食物在油炸过程中吸油量的研究

Investigation of oil absorption rate for different food during frying

  • 摘要: 为研究不同食物在油炸过程中吸油量的规律,选用茶油、棕榈油、调和油在不同温度下对不同水分和结构的食物(薯条、馒头、面饼)进行油炸。结果表明:温度对吸油量有较大的影响,170℃时食物吸油量最快达到最高点(薯条12 min),油炸结束时食物含油量最低(p<0.05);馒头疏松多孔的结构可大大提高食物的吸油量(45%~60%),远高于薯条(15%~45%)和面饼(15%~35%)(p<0.05);食物水分越高,需要油炸的时间越长。棕榈油油炸时食物的吸油曲线最平稳,吸油量也最低,可能比茶油和调和油更适合油炸。 

     

    Abstract: In order to investigate oil absorption rate for different food during frying, French fries, teamed bun, wheat cake were used for frying in different temperature and different oils ( camellia oil, palm oil, blend oil) . The results showed that temperature had significant influences on oil absorption rate.The oil absorption rate got its maximum in the least time when the frying temperature was 170 ℃ ( French fries for 12 min) , and the oil absorption rate was the lowest when the frying was finished ( p < 0.05) .Because of loose structure, the oil absorption rate ( 45%60%) was significantly raised ( p < 0.05) , which was much higher than French fries ( 15% 45%) and fried wheat cake ( 15% 35%) .The higher moisture it contained, the longer time it could be fried.The oil absorptive line was steadier and the oil absorption rate was the lowest for palm oil frying the three foods.Therefore, the palm oil is more suitable to be used as a frying oil than camellia oil and blend oil.
