Palm oil is also called palm oil and palm oil. The oil extracted from the pericarp of palm fruit is non-drying oil.
The oil palm is originated from the west coast of Africa. In the 1970s, southeast Asian countries began to cultivate a large number of oil palm. By the 1980s, the area and output of oil palm in Southeast Asia had exceeded that of Africa
Benefits of palm oil:
1. Good stability, not easy to occur oxidation deterioration, high smoke point, so it is suitable for frying food.
2. Solid fat can be used as margarine and shortening instead of the expensive cocoa butter;
Liquid fats are used as oil in salads or cooking and have a light and refreshing taste.
A large amount of unextracted palm oil is used in the soap making industry.
The soap produced with palm oil has durable foam and strong decontamination ability.
3. Palm oil is rich in vitamin A(500-700ppm) and vitamin E(500-800ppm).
Palm oil has a high smoke point and is suitable for frying and stir-frying.
When normal cooking oil is used, when the temperature of the oil exceeds the smoke point, the chemical structure of the oil and fat changes, producing carcinogens.
The smoke point value of palm oil detected by ST123B automatic vegetable fat smoke point meter produced by Shandong Shengtai Instrument Co., Ltd. is about 230 ° C, which is much higher than that of other commonly used cooking oil, so it is suitable for frying, frying, cooking and frying.
2. Experimental steps
2. 1. Experimental apparatus
1. ST123B automatic vegetable fat smoke point instrument (developed and produced by Shandong Shengtai Instrument Co., LTD.);
2. The sample was prepared using GB/T15687. The instrument conforms to GB/T 20795 "Determination of Vegetable Fat Smoke Point".
ST123B type automatic smoke point analyzer is used to determine the smoke point value of edible oil products.
Adopt inch pure industrial true color touch screen, embedded operating system.
With the self-diagnosis function of the instrument, it can check whether there is fault and show its status.
The influence of atmospheric pressure on the test is automatically corrected and the correction value is calculated.
Optional standard RS485 interface.
