2. General considerations<br />
As a result <strong>of</strong> the recommendations <strong>of</strong> the first Jo<strong>int</strong> FAO/WHO Conference<br />
on Food Additives, held in September 1955 (1), there have been 70 previous<br />
meetings <strong>of</strong> the Committee (Annex 1). The present meeting was convened<br />
on the basis <strong>of</strong> a recommendation made at the sixty-n<strong>int</strong>h meeting (Annex 1,<br />
reference 190).<br />
The tasks before the Committee were:<br />
to elaborate further principles for evaluating the safety <strong>of</strong> <strong>food</strong> <strong>additives</strong><br />
(section 2);<br />
to undertake toxicological <strong>evaluation</strong>s <strong>of</strong> <strong>certain</strong> <strong>food</strong> <strong>additives</strong> (section 3<br />
and Annex 2);<br />
to review and prepare specifications for <strong>certain</strong> <strong>food</strong> <strong>additives</strong> (section 3<br />
and Annex 2).<br />
2.1 Modification <strong>of</strong> the agenda<br />
The Committee considered the names <strong>of</strong> the compounds branching enzyme<br />
from Rhodothermus obamensis and expressed in Bacillus subtilis, lycopene<br />
oleoresin extract from tomato and OSA (octenyl succinic acid)-modified<br />
acacia gum (gum arabic), which were on the agenda for <strong>evaluation</strong> for the<br />
first time, to be inappropriate. The Committee renamed them, respectively,<br />
branching glycosyltransferase from Rhodothermus obamensis expressed in<br />
Bacillus subtilis, lycopene extract from tomato and octenyl succinic acid<br />
modified gum arabic.<br />
A temporary acceptable daily <strong>int</strong>ake (ADI) “not specified” was allocated to<br />
the <strong>food</strong> additive cyclotetraglucose and cyclotetraglucose syrup at the sixtyeighth<br />
meeting <strong>of</strong> the Committee (Annex 1, reference 187) pending submission<br />
<strong>of</strong> information on the identity <strong>of</strong> the bacterial strain used to produce the<br />
6--glucosyltransferase and -isomaltosyltransferase (6-GT/IMT) enzyme<br />
preparation and evidence <strong>of</strong> its lack <strong>of</strong> pathogenicity and toxicogenicity. The<br />
specifications for cyclotetraglucose syrup were made tentative pending additional<br />
information on the total saccharide content and test methods and on<br />
