Embodiment 1
[0037] Embodiment 1: the influence of glucose Maillard reaction time on histamine standard substance
[0038] (1) Preparation of glucose solution and histamine standard solution. Prepared with 2m mol / L NaHCO 3 Glucose solution of 1.2 mol / L, and histamine standard solution with a concentration of 200 μg / mL was prepared with histamine dihydrochloride standard.
[0039] (2) The establishment of the Maillard reaction system. Glucose solution and histamine standard solution were mixed uniformly according to the volume ratio of 1:1, the final concentration of glucose solution was 0.6mol / L, the final concentration of histamine standard solution was 100 μg / mL, and the mixed solution was frozen and then freeze-dried.
[0040] (3) Maillard reaction of glucose and histamine standards. The freeze-dried samples were placed in a 60°C incubator for 0, 0.5, 1, 2, 3, 4, 5, and 6 hours, and the 100 μg / mL histamine standard solution was used as a control to detect the Maillard reaction after di...
Embodiment 2
[0041] Embodiment 2: adopt salt sugar water treatment (2.0% salt and 1.0% fructose) to reduce the processing method of histamine in canned mackerel, comprise the following steps:
[0042] (1) Thawing: Spray and thaw the frozen mackerel with clean water until the fish body temperature is 0°C;
[0043] (2) Pre-treatment: remove the head, tail and internal organs of the fish after thawing, and wash the blood stains, black film and gills in the abdominal cavity with clean water;
[0044] (3) Slicing and cleaning: the fish body is evenly cut into 2.0cm fish pieces, and washed repeatedly with clear water for 3 times to remove residual blood stains;
[0045] (4) Soaking: Soak the fish pieces in salt-sugar water (2.0% salt and 1.0% fructose) for 20 minutes, the soaking solution needs to be replaced each time, and the temperature is controlled below 10°C;
[0046] (5) Canning and cooking: before filling, the empty cans are sprayed and rinsed with 85°C hot water. During the canning pro...
Embodiment 3
[0053] Embodiment 3: adopt the processing method of salt sugar water treatment (3% salt and 2.0% glucose) to reduce the histamine in canned mackerel, comprise the following steps:
[0054] (1) Thawing: Spray and thaw the frozen mackerel with clean water until the fish body temperature is 4°C;
[0055] (2) Pre-treatment: remove the head, tail and internal organs of the fish after thawing, and wash the blood stains, black film and gills in the abdominal cavity with clean water;
[0056] (3) Cutting and cleaning: the fish body is evenly cut into 1.5cm fish pieces, and washed repeatedly with clear water for 5 times to remove residual blood stains;
[0057] (4) Soaking: Soak the fish pieces in salt-sugar water (3% salt and 2.0% glucose) for 15 minutes, the soaking solution needs to be replaced each time, and the temperature is controlled below 10°C;
[0058] (5) Canning and cooking: before filling, the empty cans are sprayed and rinsed with 80°C hot water. During the canning proce...
