Description

Technical Field

[0001] The invention relates to the technical field of food processing, and in particular to a non-cloudy soup chili oleoresin and a preparation method and application thereof. Background Art

[0002] Capsicum oleoresin is an oily liquid extracted and concentrated from natural peppers. It is a natural plant food extract with a strong spicy taste. The main components include capsanthin and capsaicinoids. In addition, it also contains a small amount of pectin, protein, fatty acids, polysaccharides and other active ingredients. It has important functions such as antioxidant, antibacterial and anti-tumor, and is mainly used in the production of food additives, seasonings, etc.

[0003] "Hot pot turbid soup" is a term specific to the hot pot industry that is often mentioned by hot pot base producers, hot pot restaurant operators, and hot pot lovers. It refers to the phenomenon that the oil and water produced in the process of eating hot pot become miscible, resulting in the formation of a clear emulsified layer between the oil layer and the water layer until the entire soup is emulsified. The basic cause of hot pot turbid soup is that with the participation of emulsifying substances, the shear force caused by long-term boiling causes the oil and water to emulsify, resulting in a milky emulsion, which reduces the transparency of the water or oil. The turbid soup phenomenon seriously affects the quality of the hot pot, and chili oleoresin is one of the causes of the turbid soup phenomenon.

[0004] At present, there are few chili oil resin products developed for hot pot turbid soup, and the process is complicated, which is not conducive to industrial production. For example, the Chinese patent with publication number CN115024478A discloses a method for refining chili oil resin, which uses three-stage molecular distillation to treat chili oil resin, and mixes the secondary and tertiary light phases for use, so that the chili oil resin can produce less oil-water emulsification, but the cost is high and it is not easy to industrialize. The Chinese patent application with publication number CN117918507A discloses a chili oil resin and its preparation method and application, using a mixed solvent to dissolve chili oil resin, and then saponifying the mixture with alkaline water to obtain saponins; the mixed solvent is used to extract the saponins; the extract is mixed with CaCl2, filtered and concentrated to obtain concentrate I; the concentrate I is mixed with low-carbon alcohols, extracted, and the alcohol layer is concentrated to obtain concentrate II; the concentrate II is mixed with ethyl acetate for extraction, the extract is treated with salt water, and the ethyl acetate layer is concentrated after separation to obtain chili oil resin. Although the product is not turbid soup, the operation is complicated, a large amount of solvent is consumed, and the cost is high. Therefore, it is urgent to develop a simple and low-cost method for preparing chili oleoresin without turbid soup, which can be specially applied to the hot pot market. Summary of the invention

[0005] Technical problem to be solved: In view of the problem of turbid soup caused by chili oleoresin in hot pot in the prior art, the present invention provides a chili oleoresin for turbid soup and a preparation method and application thereof. The method is simple to operate and has good effect. The prepared chili oleoresin is resistant to storage and has strong stability. After being placed for 6 months, it is boiled in water and still has a good turbid soup effect.

[0006] Technical solution: A method for preparing a non-turbid soup chili oleoresin, the steps are as follows:

[0007] Step 1: Add capsicum oleoresin into a container, heat it in a water bath to 50-60°C, and keep the temperature constant for later use;

[0008] Step 2, adding deionized water into a container, washing the capsicum oleoresin with water, stirring while adding water to obtain a mixed solution, wherein the amount of water added is 20-50wt% of the capsicum oleoresin;

[0009] Step 3: Heat the mixed solution in a water bath at 50-60°C and stir for 2-3 hours to allow the water layer and the oil layer to fully contact and promote the rapid dissolution of the water-soluble substances into the water layer;

[0010] Step 4: let the mixed solution stand at a low temperature of 2-4°C for 4-8 hours, until the water layer and the oil layer are completely separated, discard the water layer, and obtain the hydrated and impurity-free capsicum oleoresin;

[0011] Step 5, dehydrating the oleoresin capsicum after hydration and impurity removal;

[0012] Step 6: Weigh the mass of the capsicum oleoresin after removing water, add rosemary extract according to 3-6‰ of the mass of the capsicum oleoresin, and stir magnetically for 1-2 hours to completely dissolve the rosemary extract in the capsicum oleoresin to obtain a turbid capsicum oleoresin product.

[0013] Preferably, the capsaicin content of the capsicum oleoresin in step 1 is 5±0.05-10±0.05wt%.

[0014] Preferably, the temperature of the water in step 2 is 20-50° C. higher than the temperature of the capsicum oleoresin to promote rapid dissolution of the water-soluble components in the water.

[0015] Preferably, the stirring rate in step three is 100-150 r / min, and the stirring method is magnetic stirring or spiral stirring.

[0016] Preferably, the water removal method in step 5 is vacuum water removal. During the vacuum water removal, the vacuum degree is -90 to -100 kPa, the temperature is 70 to 90° C., and the time is 2 to 4 hours.

[0017] Preferably, the rosemary extract in step six is ​​fat-soluble, and the content of carnosic acid, an effective ingredient, is greater than 20 wt%.

[0018] A non-turbid soup chili oleoresin is prepared based on the above method.

[0019] Based on the above application of the non-cloudy soup chili oleoresin in the preparation of hot pot base.

[0020] The invention adopts water washing to process the capsicum oleoresin, and the water-soluble macromolecular substances in the capsicum oleoresin can be removed by fully contacting the capsicum oleoresin with water, so as to avoid the phenomenon of turbid soup caused by the dissolution of such substances in the boiling process. In addition, since the capsicum oleoresin is easy to volatilize and decompose in the high-temperature boiling process, the high-temperature resistance of the capsicum oleoresin can be improved by adding the natural antioxidant rosemary extract, the loss of the capsicum oleoresin at high temperature can be reduced, and the turbid soup phenomenon caused thereby can be avoided. The finally prepared product has good high-temperature resistance and storage resistance, and the water layer still has good light transmittance when boiled in boiling water for 1-2 hours, and no turbid soup phenomenon is generated, and the hot pot soup has low turbidity.

[0021] Beneficial effects:

[0022] (1) The capsicum oleoresin used in the present invention is the capsicum oleoresin prepared with an emulsifier, has good fluidity and is easy to operate.

[0023] (2) The chili oleoresin prepared by the present invention is added to water at 1-2 wt % and a simulated boiling experiment is carried out, which still has good performance and can keep the oil layer and the water layer clearly separated, the water layer is clear, the oil layer is transparent, and the soup does not become turbid after long-term boiling.

[0024] (3) The capsicum oleoresin prepared by the present invention is storable and has strong stability. After being placed for 6 months, a boiling experiment is carried out and the turbidity of the hot pot soup is still good. BRIEF DESCRIPTION OF THE DRAWINGS
