　　Household edible peanut oil if stored properly, it is easy to cause deterioration, deterioration of peanut oil consumption, the human stomach has a strong stimulating effect, and even cause poisoning. In order to prevent the deterioration of peanut oil in Ji'nan, the following measures can be taken:

　　1、要合理地選擇花生油的儲存容器。油多時可選用陶瓷缸，盡量減小容器的口徑;油少時可選用不透光的深色的玻璃瓶。油裝滿后，應密封瓶口，使油和空氣隔，防止食用油氧化變質。人們往往習慣用金屬或塑料瓶盛裝食用油，實際上是很不科學的，因為金屬分子和塑料中的增塑劑，能加速食油的酸敗變質。

　　1, it is necessary to reasonably select the storage containers for peanut oil. For a long time, the ceramic cylinder can be used to minimize the caliber of the container. When the oil is low, the dark glass bottle with opaque light can be used. When the oil is full, seal the mouth of the bottle, insulate the oil from the air and prevent the oxidation of the cooking oil. It is often used with metal or plastic bottles containing edible oil, in fact is not scientific, because the metal molecules and plasticizers in plastics, can accelerate the deterioration of edible oil.

　　2、儲存的容器應放置在陰涼、避光、干燥、溫度低的地方。由于陽光中的紫外線和紅外線能促使油脂的氧化和加速有害物質的形成，所以，儲油的容器應盡量減少與空氣、陽光的接觸。

　　2, storage containers should be placed in a cool, light, dry, low temperature place. Because the ultraviolet and infrared rays in the sun can promote the oxidation of oil and accelerate the formation of harmful substances, the oil storage containers should minimize the exposure to air and sunlight.

　　3.、儲存花生油要防止高溫。儲存溫度以10℃---15℃為好,一般不應超過25℃，因此，夏季不宜儲存，應盡量購買新鮮花生油，建議購買農家小院自榨花生油，經常食用新鮮油。另外要注意，食油內不能混入水分，否則容易使油脂乳化，混濁變質。也可按40：1的比例往油中加入熱油，可起到吸收水的作用。

　　3., store peanut oil to prevent high temperature. Storage temperature to 10 degrees ---15 degrees for the best, generally should not exceed 25 degrees, therefore, the summer should not be stored, should try to buy fresh peanut oil, it is recommended to buy farm yard self squeezed peanut oil, regular consumption of fresh oil. Also note that cooking oil can not be mixed with water, or easy to make oil emulsion, opacity deterioration. It can also add hot oil to the oil according to the proportion of 40:1, which can absorb water.

　　4. 防止花生油的氧化變質。若單位發(fā)放或親朋好友饋贈食用油較多一時吃不完時，可選用花椒、茴香、桂皮、丁香、維生素C等抗氧化劑少許加入油中，以延緩或防止食用油的氧化變質。除選用有色小口玻璃瓶儲存外，其余的容器儲存期以半年為宜，長也不應超過一年。

　　4. prevent the oxidation of peanut oil. If the units issued or friends and family gifts edible oil more a moment can not eat, can use pepper, fennel, cinnamon, clove, vitamin C and other antioxidants added a little oil, to delay or prevent the oxidation of edible oil. In addition to the use of colored small mouth glass bottle storage, the remaining containers stored for six months is appropriate, the longest should not exceed one year.
