<P>PROBLEM TO BE SOLVED: To provide a light-irradiation method and light-irradiation apparatus for agricultural products, fishery products or livestock products giving new added value in addition to increase in amino acid content. <P>SOLUTION: The agricultural products, etc., are irradiated with blue visible light (central wavelength region: 450 nm) to increase contents of antioxidative substances such as polyphenols, physiologically active substances such as GABA or nucleotides such as inosinic acid, guanylic acid, etc., other than amino acids. The contents of these substances can also be increased by using ultraviolet rays of UV-A region in place of the blue visible light. <P>COPYRIGHT: (C)2011,JPO&INPIT |
