Peanut oil has a balanced nutritional profile, and both everyday selection and storage have their finer points

Peanut oil is an edible vegetable oil made from peanut kernels through pressing or solvent extraction, and it is one of the common cooking oils in the kitchens of urban and rural residents in our country. Its color is mostly light yellow to light brown, with a distinct peanut aroma, and using it for cooking adds flavor to dishes.

In terms of processing, peanut oil is mainly divided into two categories: pressed and solvent-extracted. Among pressed peanut oils, there is a distinction between the rich-aroma type made by roasting the seeds before pressing and the light-aroma type made by low-temperature pressing, and the commonly seen traditional-pressed and small-pressed oils on the market mostly follow the rich-aroma route. When buying, consumers can learn about the specific process and raw material information from the label, and choose the product that suits them.

Peanut oil has a relatively high content of unsaturated fatty acids and contains fat-soluble components such as vitamin E. Its smoke point is also relatively high, making it suitable for many everyday cooking methods such as pan-frying, stir-frying and deep-frying, and it is a common choice for household oil. Of course, any oil should be used in controlled amounts, and alternating it with other oils will make the nutritional structure more balanced.

For storage, peanut oil should be kept away from light, sealed, and placed in a cool, dry place, avoiding proximity to the stove where high temperatures can affect it, and after opening it is best to use it up within a relatively short time. If there is an obvious rancid smell or unusual cloudiness and sediment, it indicates that the oil may have oxidized and deteriorated and is no longer suitable for consumption. When buying, it is recommended to purchase through regular channels products with intact packaging and complete production information, to ensure quality and food safety.
