Abstract: The invention provides a fermented onion composition having a dry matter content of at least 8 wt. %, said composition comprising, per gram of dry matter: 75-800 mg acid equivalent of organic acid selected from propionic acid, lactic acid, acetic acid and combinations thereof; 2-200 mg acid equivalent of onion acid selected from selected from citric acid, malic acid, tartaric acid, oxalic acid, pyruvic acid, succinic acid and combinations thereof; 0-150 mg of saccharides selected from fructose, glucose, sucrose and combinations thereof; 0-40 mg of onion protein; wherein the combination of components a) to d) constitutes 50-95 wt. % of the dry matter that is contained in the composition. The fermented onion composition of the present invention may suitably be applied as a food ingredient in edible products as it has useful functional properties.

Abstract: The invention relates to a fermented onion composition having a dry matter content of at feast 8 wt. %, said composition comprising, per gram of dry matter: a) 0-150 mg of saccharides selected from fructose, glucose, sucrose and combinations thereof; b) 5-250 mg of phenols selected from acid equivalent of gallic acid, acid equivalent of ferulic acid, quercetin, kaempferol and combinations thereof; c) 75-500 mg acid equivalent of organic acid selected from propionic acid, lactic acid, acetic acid and combinations thereof, The fermented onion composition of the present invention can advantageously be used as an effective, label-friendly food ingredient to increase overall quality of foods. The invention also provides a method of preparing a fermented onion composition, comprising: providing an onion substrate containing 10-50 wt. % dry matter and 50-90 wt. % water, wherein at least 40 wt.
