1             Name

This instrument is the Food Standards (Application A1176 – Enzymatic Production of Steviol Glycosides) Variation.

2             Variation to standards in the Australia New Zealand Food Standards Code

The Schedule varies Standards in the Australia New Zealand Food Standards Code.

3             Commencement

The variation commences on the date of gazettal.

Schedule

[1]           Schedule 3 is varied by

[1.1]        omitting subsection S3—35(1), substituting

(1)      In this section:

prescribed rebaudiosides are:

(a)      rebaudioside D;

(b)      rebaudioside M; and

(c)      rebaudioside AM.

rebaudioside AM means the steviol glycoside with the chemical name: 13-[(2-O-β-D-glucopyranosyl-β-D-glucopyranosyl)oxy]kaur-16-en-18-oic acid, 2-O-β-D-glucopyranosyl-3-O-β-D-glucopyranosyl-β-D-glucopyranosyl ester.

(1A)   This specification relates to a steviol glycosides preparation obtained from the leaves of the Stevia rebaudiana Bertoni plant.

[1.2]        omitting paragraph S3—35(2)(c), substituting

(c)by enzymatic conversion of purified stevia leaf extract to produce rebaudioside D using a protein engineered enzyme that:

(i)contains both UDP‑glucosyltransferase (EC 2.4.1.17) and sucrose synthase (EC 2.4.1.13) components; and

(ii)is sourced from Pichia pastoris strain UGT-A;

(d)by enzymatic conversion of purified stevia leaf extract to produce one or more prescribed rebaudiosides using a combination of enzymes that contains:

(i)a UDP-glucosyltransferase from Stevia rebaudiana sourced from Escherichia coli; and

(ii)a UDP-glucosyltransferase from Solanum lycopersicum sourced from Escherichia coli; and

(iii)a sucrose synthase (EC 2.4.1.13) sourced from Escherichia coli.

[1.3]        omitting paragraph S3—35(4)(a), substituting

(a)                Description—white to light yellow powder, approximately 150 to 300 times sweeter than sucrose;

1. Schedule 18 is varied by

[2.1]        inserting in the table to subsection S18—9(3), in alphabetical order

Sucrose synthase (EC 2.4.1.13) sourced from Escherichia coli K-12 containing the gene for sucrose synthase from Arabidopsis thaliana For the conversion of purified stevia leaf extract to produce one or more of the following: rebaudioside D, rebaudioside M; and rebaudioside AM GMP

[2.2]        inserting in the table to subsection S18—9(3), in alphabetical order

Uridine diphosphate (UDP) glucosyltransferase sourced from Escherichia coli K-12 containing the UDP glucosyltransferase gene from Solanum lycopersicum For the conversion of purified stevia leaf extract to produce one or more of the following: rebaudioside D, rebaudioside M; and rebaudioside AM GMP

[2.3]        inserting in the table to subsection S18—9(3), in alphabetical order

Uridine diphosphate (UDP) glucosyltransferase sourced from Escherichia coli K-12 containing the UDP glucosyltransferase gene from Stevia rebaudiana For the conversion of purified stevia leaf extract to produce one or more of the following: rebaudioside D, rebaudioside M; and rebaudioside AM. GMP
