The ST149B Automated Oxidation Resistance Tester generates a relatively stable oxygen‑free environment for food samples under short‑term ambient‑temperature conditions. When temperature and pressure rise, the fat oxidation‑resistance performance of food decreases. Compliant with ISO 6886:2004 Animal and Vegetable Fats and Oils — Determination of Oxidation Stability (Accelerated Oxidation Test), this analyzer automatically monitors oxygen‑pressure variations throughout the food oxidation process to achieve accurate evaluation of the oxidation stability of edible oils. It is applicable to both solid and liquid oil‑containing food matrices, including plant‑ and animal‑derived tissues. Samples can be tested directly without pre‑separation of fats.
This grease oxidation‑testing instrument delivers versatile performance for broad application scenarios:
★ Predict product shelf‑life and conduct oxidation‑stability research
★ Evaluate optimum storage conditions
★ Assess packaging performance
★ Compare the oxidation‑resistance performance of food products with different formulations
★ Analyze the oxidation stability of vegetable oils of diverse origins
★ Validate the performance of antioxidant additives
★ Acquire oxidation‑relevant data for raw materials and finished goods
★ Detect subtle oxidation phenomena: Certain products suffer slow, invisible oxidation, especially those with low fat content (4‑5 %). Accurate oxidation detection can be realized by combining this analyzer with gas‑chromatography techniques.
