therefore, the lower the number of peroxides, the better the quality of the fat and its state of preservation.
The acid value in an alimentary fat is a measure of the suitability of the treatment and preservation of the alimentary fats and thus the acidity represents a fundamental indicator of product genuineness. Even olive oil can reach a high free acid content when the olives are gathered and processed incorrectly.
Determination of the percentage of acidity and of the number of peroxides in oil is of considerable importance for a quality check during pressing and storage of the olives.
Soaps,
thanks to their solubility in water and insolubility in oil, can
then be separated from the fat using appropriate procedures. Food
industries use this procedure to lower the acidity of a fat
and improve its organoleptic characteristics.
Furthermore, the Foodlab system makes it possible to carry out chemical tests for the determination of chlorides, ammonia, lactic acid and urea on raw, pasteurized and skim milk and chlorides on an acqueous solution in just a few minutes.
FOODLAB SYSTEM'S ADVANTAGES
- Use of low toxicity reagents that allow easy disposal.
- Use of micro quantities of sample.
- Use of ready-to-use test tubes with previously dispensed reagents.
- Execution of tests in batches.
- Calibration with standard known samples.
- Standardization according to IFL criteria.
- High sensitivity, precision and repeatability.
- Based on spectrophotometric technology, which excludes contact between the instrument and the sample to be analyzed. Thus the system is maintenance free.
- Tested on vegetable cow's, sheep's, goat's and buffalo milk, fats, olive oil, palm oil, seed oil, and other vegetable oils.
- In compliance with the analytical standards as per regulation (EEC) no. 2568/91 and subsequent modifications.
- Can be interfaced with computer system.
- Useable for testing along the production line.
The analytical method and the instrument were subjected to evaluation tests at Sinal certified laboratories such as: the Laboratorio Standard Latte dell'Associazione Italiana Allevatori (Milk Standard Laboratory of the Italian Breeders Association) and other reference laboratory
