Rural home-pressed rapeseed oil in the urn for 2 years, it does not look bad, can still be used?

Not long ago rapeseed seeds are already harvested after planting, which does not happen to catch up with the Dragon Boat Festival vacation home, the guys may be infatuated by the aroma of the mother's cooking oil, has long loved to eat the mother's cooking. Countryside home is all to self-property of cooking oil as the key daily finished oil, the vast majority of the village people love cooking oil, because all play small began to eat, habit.

Countryside is the habitual storage of cooking oil, because it is a one-time hit, hit once cooking oil will eat a year long, which is also the minimum length of time, some are likely to forget, will eat more long-term. As we all know urns are generally all big belly, mouth slightly larger than the bottom, urn wall is a certain degree of inclination. The urn material is generally pottery glaze, plus a layer of wax on the surface, so the urn is very good, if you put the mouth sealing good la, there is no bad oil due to leakage of steam. Another pottery glaze made urn material is relatively stable, not easy to produce oil bubbles immersed in the urn.

The internal structure of the urn walls produce moldy conditions, so in short, with urn storage of cooking oil for three years, just urn mouth sealing is better, cooking oil bad chance is very low, natural probability is low and can not say that must not rot, countryside, traditional cooking oil, soybean oil, cooking oil preservation are quite simple, sealed wine jar, sealed glass bottles loaded down to the location of the shade! It can be, storage for 3-5 years is not a problem. And, vegetable oil is not like the rest of the items so short shelf life, as long as the long-term exposure to gas is basically not easy to rot.

Traditional stupidly pressed vegetable oil finished oil are more pure, and not like the cost of today's market edible blended oils, in which I do not know how many other kinds of oil or additives do not know how good or bad, that is, a single cooking oil, soybean oil and cooking oil, it is likely that there is a little residue, but will not jeopardize the quality of the vegetable oil. Therefore, the storage standard of this oil is also responded to the simple, the regulations are not as high. Rural traditional storage methods can meet the requirements of its storage standards.
