How to identify and buy excellent edible oil?

Sensory identification of various edible vegetable oils: look, smell, and taste.

One look: look at the label. The label usually shows the type, process, grade, production date, and whether genetically modified ingredients are used in the edible oil. Look at the appearance. When the ambient temperature is above 20℃, the appearance of edible vegetable oil is clear and transparent, not turbid, without precipitation, and without suspended matter. When the ambient temperature is below 20℃, the appearance of some edible vegetable oils (soybean oil, rapeseed oil, sesame oil, etc.) is clear and transparent, without turbidity, precipitation, and suspended matter. Some edible vegetable oils have some precipitation and suspended matter (peanut oil, rapeseed oil, etc.), which is normal.

Two smells: After opening the oil barrel (bottle), you can smell the unique smell of various oils. You can also drop one or two drops of oil on the palm of your hand, rub your hands, and smell it carefully. Odorless oil indicates quality problems.

Three tastes: Use clean chopsticks or glass rods, drop one or two drops of oil, and taste it on the front of the tongue.

Can edible oil be eaten after flocculation or freezing?

Vegetable oil refining equipment: Fat is fatty acid triglyceride. Due to the different carbon chain lengths of fatty acids in triglycerides and different crystallization temperatures, crystallization needs to be formed gradually, showing several different forms such as white flocculent, opaque paste, white precipitate, and white crystal. These are all normal physical phenomena.

Some consumers worry that the quality of frozen oil is not beautiful, but this worry is completely unnecessary. As the temperature changes, any edible oil will have different degrees of freezing, which is the physical property of the edible oil itself. Crystal state? The conditions for transportation and storage of edible oil (such as: the temperature in the north is low in winter, the edible oil installed on the truck is easier to freeze, and the edible oil placed in the kitchen facing north is easy to crystallize. It is also related to the variety of oil. The freezing of edible oil will not affect its taste and quality at all. For ease of use, it is recommended that consumers keep edible vegetable oil at 20℃ in winter.
