METHOD FOR CULTIVATION OF BEAN SPROUTS USING LIGHT EMITTING DIODE IRRADIATION

摘要

PURPOSE: A method for cultivation of bean sprout using light emitting diode (LED) irradiation is provided to increase the hardness and the nutrient of bean sprout. CONSTITUTION: Disinfected bean sprout seed is germinated in a constant temperature and humidity sprouting container at 22~27°C. The germinated seed is irradiated with 440-470nm wavelength of LED. The LED irradiated seed is cultivated for 4-7 days. The hardness and the nutrient content of LED irradiated bean sprout are increased compare with unirradiated bean sprout. The nutrient is free amino acid. The free amino acid is asparagines or GABA (γ-aminobutyric acid).
