Description

Technical Field

[0001] The invention belongs to the technical field of food processing, and in particular relates to a method for preparing Luzhou-flavor liquor by combining ultra-high pressure treatment with steam explosion technology. Background Art

[0002] After the human body consumes liquor, alcohol will increase the excitability of the sympathetic nerves and cause the heart rate to accelerate and blood pressure to rise. Therefore, a large number of people will feel dizzy after drinking. At the same time, long-term drinking will also cause vasoconstriction, which will further increase the resistance to blood circulation and induce symptoms of hypertension. Vasoconstriction is caused by the action of angiotensin converting enzyme ACE in the body. Angiotensin converting enzyme ACE converts angiotensin I in plasma into angiotensin II, thereby strengthening the contraction of the myocardium and causing an increase in blood pressure. Therefore, liquor products are very unfriendly to people with hypertension. Therefore, how to reduce the damage of liquor to the body's blood vessels and improve the health care effect has always been the goal pursued by technicians in this field.

[0003] Melanoidins, as the final product of the Maillard reaction, are brown or brown polymers that are finally generated after a series of reactions such as cyclization, dehydration, anti-aldehyde, rearrangement, isomerization and condensation when carbonyl compounds (sugars) react with amino compounds (amino acids, peptides, proteins, etc.) in the Maillard reaction. Melanoidins have a variety of physiological activities such as antioxidant, antibacterial, prebiotic and anti-tumor effects, and have great application prospects in the food, medicine and cosmetics industries. In particular, in recent years, it has been found that melanoidins have the function of inhibiting the activity of angiotensin-converting enzyme ACE, and high molecular weight melanoidins have a stronger ability to inhibit ACE. Therefore, the intake of high molecular weight melanoidins by the human body can significantly reduce blood pressure values. However, there are few studies on the precise generation of melanoidins of different molecular weights in the existing technology. Therefore, if a liquor rich in high molecular weight melanoidins can be provided, it will undoubtedly effectively improve consumers' acceptance of liquor products, and further develop the consumer market of liquor. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a method for preparing Luzhou-flavor liquor by combining ultra-high pressure treatment with steam explosion technology. The present invention further develops the process of traditional grain raw material fermentation and liquor making, so that the grains can effectively generate high molecular weight melanoidins during the liquor making process, thereby greatly reducing the contraction and irritation of alcohol to human blood vessels, and effectively preventing the occurrence of high blood pressure caused by drinking.

[0005] To achieve the above object, the present invention provides the following technical solutions: A method for preparing Luzhou-flavor liquor by combining ultra-high pressure treatment with steam explosion technology, wherein the moistened raw materials are treated at an ultra-high pressure of 200-500 MPa for 10-20 minutes before steaming, and then treated at a steam high pressure of 0.15-0.65 MPa for 30 seconds.

[0006] Preferably, the moistened raw materials are treated at an ultra-high pressure of 200 MPa for 10 minutes before steaming, and then maintained at a high pressure of 0.15 MPa for 45 seconds.

[0007] Preferably, the moistened raw materials are treated at an ultra-high pressure of 200 MPa for 15 minutes before steaming, and then treated at a high pressure of 0.3 MPa steam for 30 seconds.

[0008] Preferably, the moistened raw materials are treated at an ultra-high pressure of 300 MPa for 12 minutes before steaming, and then treated at a high pressure of 0.4 MPa steam for 42 seconds.

[0009] Preferably, the moistened raw materials are treated at an ultra-high pressure of 300 MPa for 12 minutes before steaming, and then treated at a high pressure of 0.45 MPa for 45 seconds.

[0010] Preferably, the moistened raw materials are treated at an ultra-high pressure of 400 MPa for 15 minutes before steaming, and then treated at a high pressure of 0.55 MPa for 45 seconds.

[0011] Preferably, the moistened raw materials are treated at an ultra-high pressure of 500 MPa for 15 minutes before steaming, and then treated at a high pressure of 0.55 MPa for 45 seconds.

[0012] Preferably, the raw materials include the following components in mass ratio: Corn 5-10%, wheat 15-20%, glutinous rice 15-20%, rice 25-30%, and the rest is sorghum.

[0013] Preferably, the components of the raw materials are mixed according to the ratio, and then subjected to sequential crushing, moistening, mixing, ultra-high pressure treatment, and steam high-pressure treatment, and then steamed at normal pressure for 55-60 minutes, and high-temperature Daqu is added at 9-12wt% of the material, and then fermented at 15-19°C for 60-180d, and finally mixed steaming and distillation is performed to obtain the Luzhou-flavor liquor.

[0014] The applicant found that when the grain raw materials for brewing wine were subjected to different ultra-high pressure treatments combined with steam explosion treatments, the grain raw materials would produce more high molecular weight melanoidins (≥100kDa) during the later processes of cooking, adding high-temperature Daqu fermentation and distillation. However, for grains that were not treated with ultra-high pressure treatment and steam explosion, the content of high molecular weight melanoidins in the later produced wine was extremely low.

[0015] This is because ultra-high pressure treatment will release more amino acids in starch-based cereal raw materials, and at the same time enhance the gelatinization properties of starch, thereby causing more amylose to dissolve. The subsequent steam explosion treatment (i.e., steam high-pressure treatment) will further degrade the branched starch in the starch after the amylose has been dissolved, and generate more small-molecule amylose chains. The combination of the two technologies allows more amylose and amino acids to dissolve. Amylose is mainly in the shape of a straight chain composed of α-1,4 glycosidic bonds. Its structure allows more functional groups to be exposed and greatly reduces the steric hindrance effect. Therefore, the contact probability between linear starch and amino acids is greatly increased, and the reaction efficiency is greatly improved under high pressure, thereby generating high molecular weight melanoidins. High molecular weight melanoidins have a great effect on Zn in ACE. 2+ The chelating ability is stronger, and the activity of ACE can be effectively inhibited, thereby significantly reducing the body's blood pressure and offsetting the negative effect of alcohol on increased blood pressure. Therefore, the liquor prepared by the present invention is very friendly to the hypertensive group.

[0016] It should be noted that in the method of the present invention, except for the ultra-high pressure treatment and steam high pressure treatment of the grain raw materials before cooking, the other brewing steps can be carried out according to the existing Luzhou-flavor liquor production process. Of course, the selection of the composition ratio of the grain raw materials in this application, on the one hand, limits the flavor style of the later wine, and on the other hand, different grain raw materials have different tannins, fats, starches, etc., resulting in different fermentation power, lipification power, and saccharification power during liquor fermentation.
