Claim 10:
11. The system for detecting sweetness of a fruit according to claim 8, characterized in that the method further comprises:
nondestructively acquiring apparent diffusion coefficients of a fruit sample and acquiring an apparent diffusion coefficient of a first reference object at the same time by means of magnetic resonance diffusion weighted imaging;
determining an effective apparent diffusion coefficient of the fruit sample according to the apparent diffusion coefficients of the fruit sample;
detecting sample sweetness of the fruit sample; and
establishing a second sweetness detection model according to the apparent diffusion coefficient of the first reference object and the effective apparent diffusion coefficient and the sample sweetness of the fruit sample, wherein the second sweetness detection model represents a correlation between the sweetness of the fruit and two items, the effective apparent diffusion coefficient of the fruit and the apparent diffusion coefficient of the reference object;
wherein an apparent diffusion coefficient of a second reference object is acquired while the apparent diffusion coefficients of the fruit to be detected are nondestructively acquired; the second reference object is a same substance as the first reference object; and the sweetness of the fruit to be detected is determined further according to the apparent diffusion coefficient of the second reference object and by using the second sweetness detection model.
