Why use polyols?
Polyols provide a significant proportion of the sweetness of sugar, whilst also offering a valuable calorie reduction. Two notable effective options are:
• Xylitol – the same sweetness as pure sucrose, but with 40% fewer
calories at 2.4kcal/g, as compared to 4kcal/g for sugar.
• Erythritol – approximately 60-70% of the sweetness of pure sucrose,
with 100% fewer calories. Erythritol contains so little useable energy
content that, under current UK/EU labelling regulations, it is
considered to be zero-calorie.
Restrictions on Use
– for example sugar-free sweets, and chewing gums.
Polyols have been used in food products for many years, and are widely utilised and accepted in some product categories already – for example sugar-free sweets, and chewing gums. They’re so effective in the latter that there are
approved health claims for their use, primarily related to improved dental hygiene. There has been limited use in cakes and baked goods to date, largely due to technological challenges with texture changes, all of which are overcome thanks to the unique formulation and process used to make SweetAble.
As with many types of additive, there are specific conditions that must be met in order to be able to use polyols in food products. In the categories for which
SweetAble is most useful, these conditions generally permit use on a quantum satis basis (i.e., no maximum limit, but must not exceed the level required to perform the intended function), and only in ‘energy reduced’ and ‘no added
sugar’ products. We envisage the former to be the more significant for applications of SweetAble, and this requires that the finished product complies with the ‘Energy-reduced’ claim type as defined in the Annex to Regulation (EC) 1924/2006, i.e., a 30% reduction in calories as compared to the full
sugar/fat original recipe. This is an area where SweetAble excels – please visit the recipe page for a small selection of examples illustrating products with at least 30% calorie reductions (along with significant sugar, fat, and saturated fat reductions), all of which are benchmarked against their full-sugar/fat equivalents on appearance, texture, and flavour.
In the US, the polyols used in all current formulations have been issued or accepted as having GRAS (Generally Recognised as Safe) status.
Labelling
As SweetAble’s unique attributes are the result of a patent-protected
manufacturing process rather than a complex formulation, the on-pack
declaration is generally relatively short and simple – typically just one or more
vegetables, one or more polyols, and water in some of the formulation types. There are a large number of different variations, each of which is adjusted to
suit specific application requirements, and the particularly labelling declaration
will vary between each of these. We therefore advise this is discussed on a case-by-case basis.
Foods containing more than 10% added polyols typically also require additional labelling particulars in accordance with Annex III of Regulation (EU) 1169/2011,
and this will need to be determined by the user for their specific application(s). Nonetheless it should be noted that many types of product can use SweetAble
to achieve 30% calorie reduction along with large sugar and fat reductions,
without exceeding this 10% polyol threshold. The recipes section of the website contains some illustrative examples.
Natural status
As there is no harmonised regulatory definition of natural in the UK and EU, other than the regulations specifically relating to flavours, the question of whether SweetAble can be labelled as ‘natural’ is something that needs to be considered individually depending on the user’s target market. For the UK, there is a guidance document from the FSA, giving a fairly narrow and specific outline of what in their view accords with the consumer expectations of the term ‘natural’.
Two far simpler questions, but equally relevant in terms of the technical aspects of labelling/marketing:
1. Is SweetAble an artificial sweetener, or does it contain artificial sweeteners?
No, and no.
2. Are all of the components of SweetAble made from natural raw
materials?
A definitive yes.
The vegetable components are used whole, and there are no selective extraction processes or similar, so for example a carrot-based SweetAble
is made from whole carrots with nothing removed.
Whilst polyols exist in nature in various plants – for example, raspberries and strawberries contain xylitol – most sources contain relatively low levels, such that it would be very wasteful and highly inefficient to extract it from them. We therefore use polyols that are made by processing natural raw materials such as surplus corn cobs or wood pulp left over from
paper-making processes
What’s the secret
of SweetAble’s
functionality?
I (Ben) can’t tell you that, as it’ll upset Steve, and we don’t want to upset him as he makes large quantities of very tasty cakes…
Also there is a patent.
