Abstract

The invention discloses an ultraviolet-visible illumination fruit and vegetable fresh-keeping device and application of the ultraviolet-visible illumination fruit. The ultraviolet-visible illumination fruit and vegetable fresh-keeping device comprises an illumination control system and an illumination internal environment, wherein the illumination control system is arranged on a control platform outside a box body, the illumination control system comprises a control keyboard, a high-precision dimming measuring and control instrument, an illuminance measuring and control instrument, a relative humidity measuring and control instrument and a temperature measuring and control instrument; and the illumination internal environment comprises an ultraviolet light source, an LED (Light Emitting Diode)(red, yellow, blue and green) and other monochromatic sources, and a matched sensor. According to the ultraviolet-visible illumination fruit and vegetable fresh-keeping device, by using an ultraviolet sterilization function and a specific visible light physiological accommodation function, rotting and ageing processes of fruits and vegetables are controlled from two aspects including pathology and physiology, microorganisms carried in the surfaces of the fruits and the vegetables are killed, and the quality and functional ingredients of the fruits and the vegetables are kept, and thus an ideal refreshing effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of fruit and vegetable fresh-keeping equipment, and in particular relates to an ultraviolet-visible light-emitting fruit and vegetable fresh-keeping device and its application. Background technique [0002] As a green and safe alternative to traditional thermal sterilization, in recent years, short-wave ultraviolet (UV-C, wavelength 240nm-260nm) irradiation has been widely used in food safety control, inducing disease resistance of fresh agricultural products, improving functional ingredients, and delaying ripening and aging. attention. In recent years, research on UV-C in fruit and vegetable preservation and food safety control has been increasing, and it has been widely verified in inducing fruit and vegetable to produce disease resistance and functional components. The U.S. Food and Drug Administration (FDA) and the U.S. Department of Agriculture (USDA) have deemed UV safe. UV-C irradiation of fruits an...
