Measure the iodine value of oil and fat, can you judge adulteration?
Each kind of oil has a certain range of iodine value, such as soybean oil 124murmur139, palm oil is 50Mel 55, so the iodine value can determine whether the oil is adulterated or not. Q: if 10% palm oil is mixed in soybean oil, can it be judged from the determination of iodine value that soybean oil is adulterated? According to the theoretical calculation, it is assumed that the iodine value of soybean oil is 135 and palm oil is 50, then 135-90%-50-10%-126.5. This calculation is also within the range of iodine value of soybean oil, that is, it cannot be measured. I wonder if this calculation is correct?
