Abstract
A method for the assessment of the bioavailability of folates in foods is described. It involves measuring the response of selected tissue s tores (plasma and liver) to test diets in the folate-depleted rat. Ele ctron-irradiation of dried spinach (10 kGy) and dried asparagus (5 kGy ), and gamma-irradiation of egg yolk powder (2 kGy) caused no signific ant loss of folates, neither in analytically determined folate levels nor in bioavailability of folates.
