The invention relates to the technical field of raw milk detection, and discloses an automatic detection device for a raw milk sample, and the automatic detection device comprises a mechanical arm mechanism, an information acquisition mechanism, an incubation mechanism, a detection mechanism and a control mechanism. According to the embodiment of the invention, by arranging the mechanical arm mechanism, the mechanical arm mechanism can be used for automatically taking the sample, so that manual operation is not needed. By arranging the incubation mechanism, batch incubation and batch cleaning of the sample cups can be carried out, ultrasonic treatment can be carried out, the incubation rate and the cleaning rate are increased, and the cleanliness of the sample cups can be improved. Furthermore, according to the embodiment of the invention, the detection mechanism is arranged, so that the samples can be detected in batches, various items such as a raw milk viscosity item, a raw milk bacterial colony total number item and a raw milk somatic cell item can be detected at the same time, and compared with the current manual single item detection, the detection efficiency can be obviously improved.

To provide an evaluation method of flavor degradation of container-packed milk at the time of being stored at a room temperature.SOLUTION: A milk flavor evaluation method includes a quantification step of quantifying (Z)-6-dodecene-4-olide. The milk may be milk stored at 15 to 40°C. The quantification step may be a step of quantifying a content of (Z)-6-dodecene-4-olide contained in the milk by a GC-MS method.SELECTED DRAWING: None

The utility model discloses a filtering and impurity removing device for cow milk detection, which comprises a refrigeration box provided with a hollow cylindrical shell structure, and a motor is mounted on the surface of the refrigeration box; a drainage mechanism is arranged in the refrigeration box, and the drainage mechanism is characterized in that a rotating shaft is embedded in the refrigeration box, the surface, observed from one end of the rotating shaft, of the refrigeration box is connected with an output shaft of a motor, a transverse plate is fixedly connected to the surface of the rotating shaft, and the transverse plate is arranged in the refrigeration box; and an opening I is formed in the transverse plate in a penetrating manner. According to the filtering and impurity removing device for cow milk detection, the drainage mechanism is arranged, materials can be guided to the surface of the filter screen, impact on the filter screen is reduced, the materials move downwards along the surface of the guide plate, meanwhile, the rotating shaft drives the guide plate to move, the materials can evenly fall on the surface of the filter screen through the guide plate, and the materials are prevented from being accumulated on the surface of the filter screen; the filter screen is prevented from being blocked and the filtering efficiency is improved.

The invention relates to the technical field of food microorganism detection, and discloses a real-time detection method for microbial pollution of normal-temperature pure goat milk. The method comprises the following steps: dividing a target goat milk sample into a plurality of detection units representing independent production batches, collecting microbiological detection data, physicochemical property data and spectral characteristic data of each unit, and integrating to form a multi-source detection data set; and constructing a pollution risk scoring index and a quality stability evaluation index based on the data set, and dynamically generating an initial pollution risk value through an early warning trigger mechanism and model operation. And dynamically correcting the initial pollution risk value according to the time sequence correlation of the adjacent detection units to generate a corrected risk value. And performing sorting processing on the corrected risk values, creating a risk level priority form, and connecting a real-time monitoring platform to perform visual display and alarm output. According to the method, multi-source data fusion analysis is realized, high-risk batches can be identified in time, and an efficient means is provided for quality control of normal-temperature pure goat milk.
