Oxidation Test Reactor

OXITEST is the innovative advanced analytical solution for oxidation stability studies of Velp Scientifica. Chemical reactions occurring between atmospheric oxygen and food sensitive components are some of the most important causes of product degradation. Specifically, fat oxidation is recognised as one of the main factors which affects food shelf life. OXITEST is able to provide the lab operator with high added value information related to the fat oxidation processes in samples of foods such as milk powder, cheese, pasta sauces, bread substitutes, oils and fats.

The determination of the oxidation stability of samples (solid, doughy or liquid), in order to determine their quality or to determine their state of preservation is made directly on the whole sample, without preliminary fat separation. The operational activities are extremely simple and intuitive and allow time saving for the lab operator. The evaluation of oxidation stability can be accelerated, using comparatively high temperatures (20 - 110°C), in the presence of a measurable oxygen pressure.

Useful information is obtained by recording the decrease of oxygen pressure, since oxygen is consumed during fat oxidation. The instrument is equipped with two separate titanium oxidation chambers in order to analyze the same sample in duplicate or to analySe different samples at the same time and in the same working conditions. Up to two instruments can be operated from a single PC with USB connection.

The software controls the entire operation in a user friendly way. The operator can visualiSe the data recorded in a database, compare tests, export the data to an Excel file, filter and order the data.

Most important fields of application: oxidation stability of oils, fats or of food and feed samples, rapid comparison among different product formulas or verification of different lots of the same raw material, evaluation of the performance of different packaging materials and evaluation of the effectiveness

of the antioxidants.
