alpha-Amylase from Bacillus stearothermophilus

INS 1100(ii)

Listed as a flour treatment agent by Codex.

Listed as flour treatment agents (Codex)

Alpha-amylase from Bacillus stearothermophilus is a heat-stable enzyme, useful where starch must be broken down at high temperature: in syrup manufacture and in bread that stales more slowly.

Where it is and isn’t permitted

Status of alpha-Amylase from Bacillus stearothermophilus by jurisdiction. Every jurisdiction this site covers is listed, including those where the substance does not appear.

Australia and New ZealandFood Standards Australia New ZealandNo listed food uses foundThis site has not matched this substance to any food use on this jurisdiction’s list of authorised food additives. A food additive may be used only in foods that list names. Flavourings, enzymes, processing aids and added nutrients are regulated separately and do not appear on it.

Existing additives, natural flavouring agents and ordinary foods used as additives are permitted outside that list and are not imported, so an empty row does not show that Japan does not permit the substance.

Mixed preparations and sanitisers are not imported, and an entry whose identifiers disagreed with a page’s is held for review, so an empty row does not show that South Korea does not permit the substance.

How much is permitted

A listing usually limits the quantity as well as the food. Only one of the forms that takes is a figure: quantum satis and good manufacturing practice permit the amount the technological effect requires and no more, which is a limit rather than the absence of one. Figures below are the range across every food category this page is listed in, and categories differ between regulators — see how much is permitted.

Codex Alimentarius—1 GMP

No regulator sets a figure for alpha-Amylase from Bacillus stearothermophilus. That is not an absence of control: where the listing says quantum satis or good manufacturing practice, the quantity is limited to what the effect requires.

What it is made from

Produced by fermenting Bacillus stearothermophilus. Its heat tolerance reflects the organism's own habitat.

How JECFA defines it

The international specification for identity and purity, prepared by the Joint FAO/WHO Expert Committee on Food Additives and published by FAO. It is a different document from any above, written by a different body and revised on its own cycle; it is advisory, and a country adopts it or does not.

Common questions

Assembled from what is above, in the words the questions are usually asked in. Each answer is the same statement the relevant section makes, with the same citations behind it.

What is INS 1100(ii)?
INS 1100(ii) is alpha-Amylase from Bacillus stearothermophilus. Alpha-amylase from Bacillus stearothermophilus is a heat-stable enzyme, useful where starch must be broken down at high temperature: in syrup manufacture and in bread that stales more slowly.
What is alpha-Amylase from Bacillus stearothermophilus used for in food?
It is listed as a flour treatment agent — the role Codex assigns it. This page shows every function each regulator records, with the citation for each.
Where is alpha-Amylase from Bacillus stearothermophilus permitted?
Of the seven regulators this site reads, the Codex standard permits it. Each permission is for named foods at named levels, not a blanket one; the table on this page gives them with citations.
Is alpha-Amylase from Bacillus stearothermophilus vegan?
Yes. alpha-Amylase from Bacillus stearothermophilus is not derived from animals, and is suitable for vegetarians. This page says what it is made from and how.
