ST149B Automatic oxidation stability meter
According to ST149B automatic oxidation stability apparatus according to the food in the room temperature in a closed condition, oxygen under the environment of no overpressure in a short time to maintain a relatively stable, when the temperature increases pressure, the food itself on the oxidation of oil will be weakened.
After the sample is placed in the test tank and sealed, oxygen is pumped into the test chamber and the sample is heated. Oxygen consumption is indicated by a decrease in pressure .Measurements continue until a tipping point is reached - a defined pressure drop. This result is called the induction period (IP), which is the time between the beginning of the test and the turning point, and it indicates the oxidation stability of the sample under test.
This product conforms to ISO 6886:2004 "animal and vegetable oil -- determination of oxidation stability (accelerated oxidation test)", this instrument automatically records the change of oxygen pressure in the process of food oxidation, through this method can know the stability of food oil oxidation.
It is suitable for food containing grease, solid or liquid, including vegetable and animal tissues. It can be directly tested for food without the need to separate the grease.
The grease oxidation analyzer is a universal instrument that is widely used.
★ predict shelf life, study the oxidation stability in the process;
★ assess storage conditions;
★ evaluate packaging solutions;
★ comparison of food oxidation stability of different formulations;
To evaluate the oxidation stability of vegetable oils from different plant sources;
★ to evaluate the efficacy of antioxidants;
★ the oxidation stability of raw materials and finished products related information;
★ product oxidation information: some products are slow oxidation, is not visible, especially for low fat content (4-5%) products.
Performance characteristics
1. Instrument display: 7-inch color touch screen, beautiful and easy to operate
2. High degree of automation: automatic heating and constant temperature, automatic recording of test data and real-time display of curves.
3. Imported sensor PT100 can be used to set the experimental temperature arbitrarily.
