After frying foods, for example, chicken or cutlets(mix of meat and potato) with frying sunflower oil, the oil turns green/greenish, is this oil spoiled and bad? Shouldn't I use the rest of the oil bottle? (I mean oil that has not been used yet.) The following photos are of when the oil is cooled.
Thank you
Is this can be related to my problem?
