A visual turbidity detection device and detection method thereof includes an observing box, an observing assembly, and a light assembly. The observing box includes a box, at least one side of the box defines an observing window, and at least one side of the box is capable of being disassembled to define an opening for taking and placing a sample to be tested. The observing assembly includes a first base and a first rotation shaft. An end of the first rotation shaft is rotatably connected to a bottom wall of the box, a shaft body of the first rotation shaft is fixedly connected to the first base, another end of the first rotation shaft extends out of a top wall of the observing box, and the first base is configured to place the sample to be tested. The light assembly is disposed on an inner wall of the observing box.

The present invention discloses a method for judgment of cheddar cheese grade based on identification characteristic flavor compounds, comprising the following steps: selecting cheddar cheese of different grades as standard product, and extracting volatile flavor compounds from the standard product; using gas phase-sniffing device to screen out characteristic flavor compounds with higher flavor intensity from the volatile flavor compounds through aroma extract dilution analysis; proceeding with clustering of characteristic flavor compounds as screened out to obtain identification characteristic flavor compounds of cheddar cheese; measuring the concentration of identification characteristic flavor composition of cheddar cheese of known grade, and establish the training set for training of support vector machine; measuring the concentration of identification characteristic flavor composition of cheddar cheese to be tested, and inputting it into the support vector machine trained to judge the grade of cheddar cheese to be tested. The present invention aims to obtain the model of identification characteristic flavor compounds of cheddar cheese through statistical analysis, which is available for accurate judgment of cheddar cheese quality grade on this basis.
