Accelerated Oxidation Test Using Oxitest Oxidation Tester to Determine the Oxidative Stability of Foods, Oils and Fats
Standard Procedure AOCS Cd 12c-16: Accelerated Oxidation Test for Determining the Oxidative Stability of Foods, Oils and Fats Using OXITEST Oxidation Tester
Lipid oxidation is the main factor limiting the shelf life of fat- and oil-containing foods. Various methods are available to assess the rate of lipid oxidation in foods. However, these techniques require extracting fat from food samples prior to oxidation testing. In contrast, the Oxitest instrument (Model: ST149B Oil Oxidation Tester; Origin: China; Manufacturer: Shandong Shengtai Instrument Co., Ltd.) can analyze fat oxidation in whole food samples, providing a simpler and faster method.
1. Basic Principles and Characteristics of the Instrument
OXITEST adopts the official AOCS method Cd12c-16, accelerating the oxidation process through two factors: temperature and pressure, enabling experimental data to be obtained within hours. The instrument places the sample in a high-oxidation environment, measures the pressure change in the oxidation reaction chamber of Shengtai Instrument, monitors the oxygen consumption of reactive components in the sample, and automatically generates the Induction Period (IP) value. The longer the IP value, the better the antioxidant stability of the product.
The OXITEST software supports multiple applications:
- Repeatability testing: A series of tests performed on the same sample or standard to verify its IP period and calculate the accuracy and repeatability of data.
- Freshness testing: Verify the quality of different batches (e.g., the same raw material) and make comparisons.
- Formula comparison: Identify a stable formula for finished products under the same conditions.
- Packaging comparison: Test which packaging can keep the product fresh.
- IP during aging: Obtain a downward curve of IP of the product during its shelf life.
- Shelf life estimation: Predict the oxidative stability during the shelf life.
Compared with traditional methods, it saves analysis time and is specially designed for R&D, product development and quality control laboratories.
Shandong Shengtai Instrument Co., Ltd. provides you with excellent analytical solutions for the oxidative stability and antioxidant capacity of foods, oils and fats.
