    Residue Monograph prepared by the meeting of the Joint FAO/WHO Expert Committee on Food Additives (JECFA), 82nd meeting 2016 : Acid Treated Starch (Tentative) 2017
    Also available in:

    Prepared at the 82nd JECFA (2016) and published in FAO JECFA Monograph 19 (2016), superseding specifications for Acetylated distarch adipate included in the specifications for Modified starches prepared at the 79th JECFA (2014), published in FAO JECFA Monographs 16 (2014). An ADI “not specified” was established at the 26th JECFA (1982). Starch is a carbohydrate polymer consisting of a large number of glucose units linked together primarily by alpha 1-4 glucosidic bonds. The starch polymers come in two forms: linear (amylose) and branched through alpha 1-6 glucosidic bonds (amylopectin), with each glucose unit possessing a maximum of three hydroxyls that can undergo chemical substitution. Acid treated starch is a modified starch. It is obtained by treatment of food starch with hydrochloric acid or ortho-phosphoric acid or sulfuric acid, in accordance with good manufacturing practice. The alteration of the starch is a minor fragmentation.

Acetylated distarch phosphate is a modified starch. It is obtained by esterification/cross-linking of food starch with sodium trimetaphosphate or phosphorus oxychloride combined with esterification with acetic anhydride or vinyl acetate in accordance with good manufacturing practice. Acetylation resul ts in substitution of hydroxyl groups with acetyl esters. In cases of cross-linking, where a polyfunctional substituting agent, such as phosphorus oxychloride, connects two chains, the structure can be represented by: Starch-O-R-O-Starch, where R = cross-linking group and Starch refers to the linear and/or branched structure.

    Rebaudioside a From Multiple Gene Donors Expressed in Yarrowia Lipolytica
    Residue Monograph prepared by the meeting of the Joint FAO/WHO Expert Committee on Food Additives (JECFA), 82nd meeting 2016

    Prepared at the 82nd JECFA (2016) and published in FAO JECFA Monograph 19 (2016), superseding specifications for Oxidized starch included in the specifications for Modified starches prepared at the 79th JECFA (2014), published in FAO JECFA Monographs 16 (2014). An ADI “not specified” was established at the 26th JECFA (1982). Rebaudioside A is a steviol glycoside composed predominantly of rebaudioside A with minor amounts of other steviol glycosides such as rebaudioside B, rebaudioside D, rebaudi oside M, and stevioside. Rebaudioside A is obtained from the fermentation of a non-toxigenic non-pathogenic strain of Yarrowia lipolytica that is genetically modified with heterologous genes from multiple donor organisms to overexpress steviol glycosides. After removal of the biomass by solid-liquid separation and heat treatment, the process involves concentration of the steviol glycosides (e.g. by resin adsorption), followed by purification of the rebaudioside A by crystallization and drying. I on exchange resins may be used in the purification process. The final product may be spray-dried.
