Folic acid contents of various foods were estimated by the microbioassay using Lactobacillus casei as the test organism. Folate contents without conjugase treatments were expressed as free folate and folate contents assayed after chicken pancrease conjugase treatment were expressed as total folate. The results of folate estimation of coocked foods showed that loss of free folate during coocking was greater than that of total folate.
