1 G.C.C STANDARDIZATION ORGANIZATION (GSO) Final Draft GSO/DS 1929/2011 Edible Vegetable Oils Part II Prepared by: Gulf Technical Committee for Sector Standards of Food and Agriculture Product This document is a draft Gulf Standard circulated for comments, it is therefore, subject to Alteration and modification, and may not be referred it as a Gulf Standard, until approved by the Board of Directors.

2 Foreword GCC Standardization Organization (GSO) is a regional Organization which consists of the National Standards Bodies of GCC member States. One of GSO main functions is to issue Gulf Standards /Technical regulations through specialized technical committees (TCs). GSO through the technical program of committee TC No.: 5 " technical committee for Sector Of foods and agriculture products " has updated the GSO Standard No. (1929/ 2009) : Edible Vegetable Oils Part II. The Draft Standard has been prepared by STATE OF KUWAIT This standard has been approved as a Gulf (Technical Regulation) by GSO Board of Directors in its meeting No.( ),held on / / H, / / G. The approved standard will replace and supersede the GSO standard No. (1929/2009). 2

3 Introduction This standard is the second part of the specification of Edible Vegetable Oils, and it is complementary to the first part of which was prepared by the State of Qatar No. GSO 1745:2011. The standard international CODEX-STAN 210 (Amended 2005, 2010) has been adopted as an essential reference in the preparation of this part. This standard includes the following s: 1- Arachis 2- Babassu 3- Coconut 4- Grape 5- Rape 6- Rice bran 7- Sesame 8-9- seed high oleic acid 10- mid oleic acid 3
