Problems solved by technology

The steam distillation method consumes a lot of energy, and the fresh onion flavor is seriously lost after high-temperature cooking; the supercritical carbon dioxide extraction method can better retain the onion flavor, but the production equipment is complex and not suitable for large-scale production, and the price of the obtained onion oil is generally higher ; Organic solvent extraction generally has a certain amount of solvent residue, which has a certain impact on the flavor of onion oil

Embodiment 1

[0010] Take fresh onions, peel and clean them, then mechanically crush them to 2-4cm sized onion particles, add soybean oil at a ratio of 1:1 and mix evenly, extract at 25-35°C for 60 minutes at low temperature, press for 100 minutes after removing the slag Stand and stratify, get the onion emulsion of the upper layer and carry out centrifugation, the rotating speed is 15000r / min, the centrifugation time is 15min, filtration, filtrate filling can get yellow transparent onion oil.

Embodiment 2

[0012] Take fresh onions, peel and clean them, then mechanically crush them to 2-4cm size onion particles, add soybean oil in a ratio of 1:1 and mix evenly, leaching at 25-35°C for 240min at low temperature, pressing to remove slag, and then 120min Stand and stratify the onion emulsion, get the upper layer of onion emulsion and carry out centrifugal separation, the rotating speed is 10000r / min, the centrifugation time is 20min, filtration, filtrate filling can get yellow transparent onion oil.

Embodiment 3

[0014] Take fresh onions, peel and clean them, then mechanically crush them to 2-4cm sized onion particles, add soybean oil at a ratio of 1:1 and mix evenly, leaching at 25-35°C for 180min at low temperature, pressing to remove slag, and then 60min Stand and stratify, get the onion emulsion of the upper layer and carry out centrifugation, the rotating speed is 5000r / min, the centrifugation time is 30min, filtration, filtrate filling can get yellow transparent onion oil.

[0015] Compared with the extraction method in the prior art, the onion oil prepared by the method of the present invention has advantages and disadvantages as shown in Table 1 below.

[0016] Table 1. The comparison of the method of embodiment 1 of the present invention and the onion oil it makes with several methods in the prior art.

Abstract

The invention relates to onion oil and a preparation method thereof. The onion oil provided by the invention is obtained through extracting oniony flavor ingredients from onions, which serve as a rawmaterial, by a lixiviating method, and then carrying out squeezing, centrifugal separation and the like. According to the preparation method, the extraction process is simple, chemical solvents are not used, the flavor ingredients of the onions are not destroyed, and the onion oil is high in yield and stable in quality, so that the preparation method is applicable to large-scale production. Meanwhile, the onion oil obtained by the preparation method provided by the invention is lifelike and natural in fragrance, full and mellow in flavor and moderate in concentration and can be directly applied to target products.

Description

technical field [0001] The invention relates to an onion deep processing method, in particular to an onion oil product and a preparation method thereof. Background technique [0002] Onion oil is generally amber yellow to amber orange transparent liquid, with a strong stimulating and long-lasting characteristic flavor of onion, the main components are diallyl disulfide, dipropyl disulfide, dimethyl disulfide, etc., mainly used It is used in soup stock, meat products, seasoning and side food, etc. At present, the preparation methods of onion oil include atmospheric pressure steam distillation, supercritical carbon dioxide extraction, and organic solvent extraction. The steam distillation method consumes a lot of energy, and the fresh onion flavor is seriously lost after high-temperature cooking; the supercritical carbon dioxide extraction method can better retain the onion flavor, but the production equipment is complex and not suitable for large-scale production, and the pr...
