  • Method of nondestructively measuring sugar content of fruit by using near infrared transmittance spectrum
    Patent number: 5324945
    Abstract: A method of nondestructively measuring the sugar content of fruit comprising irradiating the fruit with near infrared radiation such that the radiation penetrates the fruit; measuring the absorbance at a given wavelength with a wavelength selector that is placed in the optical path of the near infrared radiation; normalizing the obtained absorbance, taking account of the size of the fruit; and finding an index of the sweetness of the fruit from the normalized measured absorbance. Thus, the sugar content of fruits, especially of fruits having thick skins, can be measured nondestructively with practically acceptable accuracy.
