Title:
PREPARATION OF VITAMIN D2 IN SEAWEEDS
Document Type and Number:
Japanese Patent JPS6042364
Kind Code:
A
Abstract:

PURPOSE: To prepare a large amount of the titled compound important to health efficiently without adding a drug, etc. and without losing vitamin A, by irradiating seaweeds with ultraviolet light with wave length in a given range.

CONSTITUTION: Seaweeds such as a sea lettuce, green laver, Hizikia fusiforme, a sea tangle, etc. with ultraviolet light with 280W320mm wave length, so that ergosterol contained in the seaweeds is easily activated, to give the desired substance.

EFFECT: Heat is not generated by irradiation, and vitamin D2 obtained by irradiation is more luster than one without irradiation. Preparation is not affected by weather, and this process is a useful process.
