Barrier Performance Test in Cooking Oil Barrel

Nov. 13, 2012 - PRLog -- Cooking oil is the necessity in our life, It is an important food which can supply body heat and essential fatty acid as well as promote the absorption of fat-soluble vitamins. To measure the nutritional value of the edible oil, there are two indices, i.e. Content of unsaturated fatty acid and essential fatty acids. But the fatty acid is prone to rancidity reactions and finally lead to oil deterioration

The rancidity of Cooking oil is an natural phenomenon, We can only reduce the speed of the rancidity and can't stop grease rancidity. So It is inadvisable to buy too much cooking oil and store for a long time, In addition, if we want to reduce the edible oil’s rancidity speed in shelf and storage Period, on one hand, It must be stored in dark and low temperature. on the other hand, grease’s packing containers - Cooking oil barrel, must have higher sealing barrier properties, especially the ability to cut off water vapor and air.

According to the customer commissioned, Labthink(http://www.labthink.cn/en/) Laboratory recently had done some barrier property test of different material in Cooking Oil Barrel. Adopted standard Configuration of Perme OX2/230 oxygen transmission rate test system(http://www.labthink.cn/en/product-info-oxygen-transmission-rate-test-system-ox2-230.html) and Perme W3/330 water vapor transmission rate test system(http://www.labthink.cn/en/product-info-water-vapor-transmission-rate-test-system-w3-330.html), Labthink had accomplished 4L and below capacity edible oil barrel’s barrier performance testing. But the container of 5L and larger size need to customize temperature control devices to do temperature control test  and the barrier performance test under the conditions in laboratory environment.
