Mistake in the database (folate content after boiling)?
I think I discovered a mistake in the database.
It's about the folate content between raw lentils and boiled lentils, more specifically the folate loss through boiling.
Boiled lentils gain weight through the cooking water, approximately by a factor of 2,25 .
So the folate content in lentils of the same amount, for example 100 grams, is according to cronometer:
Lentils, raw, 100 grams: 479 micrograms of folate
Lentils, boiled, 225 grams (higher weight because of cooking water, but still the same weight of raw lentils): 407 micrograms of folate
So the loss by boiling is according to cronometer only about 15%, which is almost nothing.
Some will argue, that the factor by which lentils gain weight is even about 2,5, which would result in only about 5,5% of folate loss according to cronometer.
The literature shows, that by cooking/boiling you loose much of the folate, sometimes even up to 90% of the original content.
Also the literature shows, that on average you have losses of 40%-50% by cooking/boiling.
But according to cronometer only 5,5%-15%?
Why this low number of folate loss in the database?
