Edible Oil

  • Introduction

    Vegetable oils are triglycerides extracted from oil seeds and fruits such as olive, soy, rapeseed, sunflower, palm, cocoa and many others. These seed extracts (unprocessed called “crude oils”) are used in the food and feed industry as ingredient or as cooking oils, mentioning olive oil as the most famous one. Vegetable oils also used for industrial purposes and can be converted into biodiesel.
    Most of these crude oils need to be refined through chemicals agents (basis and acids) or via physical processes (high temperature, high pressure, cold pressing or solvent extraction). Refined oils have usually soft tastes and a clear and transparent presentation.

    NIR Technology

    Refining Vegetable Oils quick and easy

    The transition from crude to refined oil and, as an additional step, to biodiesel occurs through typical processes:

    Extraction
    seeds on stock - incoming seeds into implant - preparation - oil extraction and residual flour - crude oil

    Refinement
    crude oil - neutralization - deodorization and discoloration - fractioning in column - refined oil

    Biodiesel
    refined oil - methanol recovery - transesterification steps - crude biodiesel and crude glycerine - biodiesel
     

    The parameters of interest during the refinement process are moisture, acidity and, in some cases, phosphorous content. They indicate the efficiency of centrifugation, the age, the effective edible part and the residual of phospholipids. All these parameters should be constantly controlled to predict the correct refining formula. Officially an equipped laboratory and trained personnel is necessary. This leads to high costs per analysis due to time and reagents consumption.

    The NIR on-line analysis allows a real time control of your production – extremely fast and with accurate results. We can rapidly analyse online each step of your processing with our system configuration and calibration performance equal to the at-line/lab installation. This system also checks by-products for water and oil residual to keep waste control.
