Embodiment Construction

[0066] The present invention will be further described below in conjunction with the drawings and specific embodiments.

[0067] Such as figure 1 The illustrated embodiment is a method for detecting the storage time of sweet oranges, which includes the following steps:

[0068] Step 100, select 15 freshly picked sweet orange samples of the same size, and store the sweet orange samples in a freezer. The refrigerating temperature of the freezer is 4°C. The following tests are performed on the sweet orange samples:

[0069] Step 101, set the number of detection days to m 1 =11, Time 1 The initial value of is 1; use a surface acoustic wave detection device to detect the frequency response of sweet oranges, and obtain the first prediction formula of sweet orange storage time:

[0070] Such as figure 2 As shown, the surface acoustic wave detection device includes a counter 1, a shielding box 2, an oscillator 3 and a surface acoustic wave resonator 4 arranged in the shielding box; the oscil...

Abstract

The invention discloses a detection method for the storage time of sweet oranges. The detection method comprises the following steps of: measuring response signals of the sweet orange samples with different storage times by virtue of combination of a gas sensor and surface acoustic wave, constructing a first predication model and a second predication model of the storage times of the sweet oranges according to response data of a gas sensor array and the detection frequency of the surface acoustic wave, establishing a comprehensive prediction model of the storage times of the sweet oranges, and utilizing the comprehensive prediction model of the storage times of the sweet oranges to predict the storage time of the sweet orange sample W. The detection method disclosed by the invention has the advantages of high speed, no damage and good accuracy, and also has the beneficial effects that the storage time and the picking time of the sweet oranges can be reasonably arranged according to the predicted storage time, so that the spoilage of the sweet oranges in transportation and storage is effectively prevented.

Description

Technical field [0001] The invention relates to the field of fruit freshness detection, in particular to a detection method for fast and non-destructive detection of the storage time of sweet oranges and high detection accuracy. Background technique [0002] Citrus Sinensis is the fruit of the orange tree of the citrus genus of the Rutaceae family, also known as yellow fruit. The fruit is round to oblong, orange-yellow, with raised oil cells, and the peel is not easy to peel. No bitterness. The center column is full, the juice is sweet and fragrant, and contains a lot of sugar, a certain amount of citric acid and rich vitamin C, which has high nutritional value. [0003] Due to the thin peel of sweet oranges, it is susceptible to changes in environmental factors during storage and transportation, resulting in quality degradation and even rot. [0004] Although the artificial sensory evaluation method can distinguish the subtle changes of sweet oranges during storage, the results of...
