Embodiment 1

[0115] An onion flavor composition having a tangy fried onion flavor was prepared as follows.

[0116] 100 g of fresh onions were sliced ​​with a slicer to make onion slices.

[0117] Onion slices were mixed with 87.5 g of onion juice concentrate (80° Bx) to make an onion mixture. The onion mixture was dried by vacuum belt drying at 140° C. and a pressure of 8 mbar for 30 minutes to obtain about 90 g.

[0118] 38 g of onion residues having a dry matter content of about 28 wt.% were dried by hot air drying at 130° C. for 200 minutes to obtain about 10 g of dried onion residues.

[0119] The dried onion mixture and dried onion pomace were mixed and ground by an impact mill to produce an onion flavor composition.

[0120] The onion flavor composition was analyzed by GC-MS. Table 1 shows the results of this analysis (concentrations by weight of the onion flavor composition (w / w)).

Embodiment 2

[0125] Instant onion cream soup having the composition shown in Table 2 was prepared by dry blending the ingredients.

[0126] Table 2

[0127]

[0128] The soup was prepared by stirring and boiling 140 g of instant soup in 1 L of water for 1 minute.

Abstract

The invention relates to a method of producing an onion flavour composition, said method comprising: providing onion component selected from fresh onion, dehydrated onion and combinations thereof; providing onion juice concentrate having a dry matter content of 40-95 wt.%; mixing the onion component with the onion juice concentrate in a weight ratio, calculated on a dry matter basis, of 100 parts by weight of dry matter from onion component with 60 to 1000 parts by weight of dry matter from onion juice concentrate, to produce an onion mix; subjecting the onion mix to a heat treatment at a temperature of more than 100 DEG C for at least 5 minutes; and drying the onion mix to a water content of less than 10 wt.% simultaneous with and / or after the heat treatment. This method yields a shelf-stable onion flavour composition that has an intense flavour, and that can suitably be used to impart the flavour of sauteed onion to a wide variety of edible products.

Description

technical field [0001] The present invention relates to a method for preparing an onion flavor composition, the method comprising: [0002] providing an onion component selected from the group consisting of fresh onions, dehydrated onions and combinations thereof; [0003] Provide onion juice concentrate; [0004] - mixing said onion components with said onion juice concentrate to make an onion mixture; [0005] · heat-treating said onion mixture at a temperature above 100°C; and [0006] • Simultaneously with and / or after said heat treatment, said onion mixture is dried to a moisture content of less than 10 wt.%. [0007] The onion flavor composition thus obtained can be suitably incorporated into edible products to impart sautéed onion flavor. Background technique [0008] Onion (Allium cepa L.) is a vegetable which is the most widely grown species in the genus Allium (Allium). Its close relatives include garlic, leeks, chives, and scallions. [0009] Onions are ofte...
