Abstract

Provided are a method and a device for maintaining the freshness of agricultural products, the method and device making it possible to reliably obtain a freshness-maintaining effect while efficientlyusing light energy by irradiating agricultural products with an appropriate amount of near-infrared light. Provided are: a method for maintaining the freshness of agricultural products, the method making it possible to reliably obtain a freshness-maintaining effect by irradiating harvested agricultural products with near-infrared light that includes a wavelength set within a wavelength region of 800-1000 nm so as to satisfy all of equations 1, 2, and 3, where X is the irradiance (W/m2) and Y is the irradiation time (sec); and a device for maintaining freshness with which it is possible to implement the method. Equation 1: 413019X-1.872 >= Y >= 5966X-1.86 Equation 2: X >= 1 Equation 3: Y >= 0.01

Description

technical field [0001] The present invention relates to a fresh-keeping method and fresh-keeping device for crops capable of maintaining the freshness of crops for a long period of time after harvesting. Background technique [0002] The preservation of crops can significantly affect the value of commodities, so it is important. As a technique for maintaining the freshness of crops, for example, refrigeration is generally used to suppress respiration and evapotranspiration of crops. However, refrigeration not only costs money, but also has problems such as insufficient refrigeration during transportation and the like. [0003] Therefore, the applicant of the present invention has been developing a novel fresh-keeping method for crops for a long time. [0004] For example, in Patent Document 1, the applicant of the present invention has developed 2 In the range of / s and the irradiation time is 1 nanosecond to 72 hours, the near-infrared light of the wavelength of 700-2500...
