Natural sweetener
The invention relates to extracts, in particular non-nutrient phytochemicals, form sugar cane or sugar beet waste products, such as molasses, sugar mud and bagasse, which have Glycemic Index (GI) lowering properties and their use as sweeteners and in foods containing sugar.
1. A sweetener having a low GI comprising:
(a) a sugar base comprising 97% to 99% of a mixture consisting of sucrose, glucose and fructose wherein the combined amount of glucose and fructose is no more than 0.5% w/w of the total sweetener; and
(b) an extract derived from sugar cane comprising:
(i) one or more organic acids selected from the group consisting of transaconitic acid, oxalic, cis-aconitic, citric, phosphoric, gluconic, malic, succinic, lactic, formic and acetic acids, wherein the total amount of acids in the sweetener is an amount in the range from 600 to 2100 micrograms per gram;
(ii) one or more minerals selected from the group consisting of calcium, magnesium and potassium, wherein the amount of minerals is in the range from 150 to 600 micrograms per gram;
(iii) one or more polyphenols in an amount in the range from 0.2 to 0.5 mg catechin equivalents per gram;
(iv) one or more antioxidants wherein the antioxidant activity is in the range of 0.4 to 1.2 micromoles per gram; and
(v) one or more polysaccharides in the range from 20 to 60 micrograms per gram.
2. The sweetener according to claim 1 wherein the one or more organic acids is a mixture consisting of 2 parts cis-acotonic acid, 1 part citric acid, 0.7 part phosphoric acid, 0.5 part gluconic acid, 1.5 parts malic acid, 12 parts trans aconitic acid, 0.3 part succinic acid and 0.2 part lactic acid.
3. The sweetener of claim 1 , wherein the amount of trans-aconitic acid forms the majority of the organic acids and is in an amount in the range from 200 to 600 micrograms per gram.
4. A sweetener having a low GI comprising:
(a) a sugar base comprising 97% to 99% of a mixture consisting of sucrose, glucose and fructose wherein the combined amount of glucose and fructose is no more than 1.0% w/w of the total sweetener; and
(b) an extract derived from sugar cane comprising:
(i) one or more organic acids selected from the group consisting of transaconitic acid, oxalic, cis-aconitic, citric, phosphoric, gluconic, malic, succinic, lactic, formic and acetic acids, wherein the total amount of acids in the sweetener is an amount in the range from 600 to 2100 micrograms per gram;
(ii) one or more minerals selected from the group consisting of calcium, magnesium and potassium, wherein the amount of minerals is in the range from 150 to 600 micrograms per gram;
(iii) one or more polyphenols in an amount in the range from 0.2 to 0.5 mg catechin equivalents per gram;
(iv) one or more antioxidants wherein the antioxidant activity is in the range of 0.4 to 1.2 micromoles per gram; and
(v) one or more polysaccharides in the range from 20 to 60 micrograms per gram.
5. The sweetener of claim 4 , wherein the amount of trans-aconitic acid forms the majority of the organic acids and is in an amount in the range from 200 to 600 micrograms per gram.
