Abstract
This invention relates to novel extracts from sugar cane and sugar beet molasses and the characterisation of those extracts. The extracts are enriched in hydrophobic compounds including polyphenols, in levels 5 to 10 fold higher than found in molasses itself Methods for extracting the extract are also described, together with new uses for the extracts as food ingredients, food modifiers and therapeutic substances.

1-7. (canceled)
A method for producing a molasses extract comprising the steps of:
- a. diluting the molasses to produce a 10 to 40% w/v aqueous solution;
- b. optionally filtering the diluted molasses produced in step (a);
- c. contacting the diluted molasses with a hydrophobic polymeric adsorbent under conditions sufficient to enable binding of hydrophobic compounds to the adsorbent and flow through of all other compounds in the diluted molasses;
- d. optionally passing the flow through from step (c) over the hydrophobic polymeric adsorbent at least once;
- e. optionally rising the hydrophobic polymeric adsorbent;
- and
- f. eluting the compounds bound to the hydrophobic polymeric adsorbent to produce the extract;
- wherein the hydrophobic compounds are eluted with 30 to 70% ethanol;
- and
- wherein the molasses extract has a high relative abundance of hydrophobic compounds including polyphenols and wherein the extract comprises:
- at least 9000 mg catechin equivalent/100 g of hydrophobic polyphenols in a mixture of free form polyphenols selected from the group consisting of apigenin, catechin, catechin gallate, epicatechin, kaempherol, luteolin, quercetin, tricin, myricetin and diosmetin;
- polyphenol glycosides selected from diosmin, tricin-7-O-neohesperidoside, orientin, vitexin, luteolin-8-C-(rhamnosylglucoside), schaftoside, isoschaftoside and rutin;
- and phenolic acids, selected from caffeic acid, chlorogenic acid, p-coumaric acid, ferulic acid, gallic acid, syringic acid and vanillic acid;
- one or more trace elements selected from the group consisting of calcium, iron, magnesium, manganese, potassium and sodium;
- protein and other nitrogen-containing compounds;
- carbohydrates other than monosaccharides and sucrose;
- and
- less than 2 g of monosaccharides and sucrose per 100 g of extract.
