Description

Technical Field

[0001] The invention relates to the field of health food, and in particular to a preparation method and application of a ganoderma spore oil oral liquid with improved taste. Background Art

[0002] Ganoderma spore oil is a fat-soluble oily substance extracted from extremely tiny oval reproductive cells ejected from the gills of Ganoderma during its growth and maturity period. It is rich in triterpenoids, sterols, vitamins and other biologically active substances. It also contains a large amount of unsaturated fatty acids such as oleic acid, linoleic acid, linolenic acid, etc., which can enhance the body's functional immunity. It also has the effects of regulating cardiovascular system, improving digestion, and regulating sleep.

[0003] Since Ganoderma lucidum spore oil is rich in unsaturated fatty acids, it is easily affected by air, light and temperature in the environment, making it easy to oxidize and become rancid during processing and storage, reducing the quality and value of Ganoderma lucidum spore oil. In addition, Ganoderma lucidum spore oil is a fat-soluble substance, which is an oily liquid at room temperature and has good fat solubility. It is difficult to be digested and absorbed by the human body when taken orally directly, and the oral absorption utilization rate is very low. Preparing Ganoderma lucidum spore oil into an emulsion oral liquid is a good idea to solve the above problems. Emulsion oral liquid can effectively increase the stability and bioavailability of Ganoderma lucidum spore oil.

[0004] High-pressure homogenization is one of the most commonly used methods for preparing emulsions at present, but high-pressure homogenization requires relatively high pressure, and often requires cyclic high-pressure homogenization to obtain nanoemulsions with small particle size and good stability. "A method for preparing a nanoemulsion of whole ganoderma spore oil rich in ganoderma acid" (publication number CN112043731A) discloses a method for preparing a nanoemulsion of ganoderma spore oil by repeated high-pressure homogenization, and homogenizing 8 to 12 times under the condition of a homogenization pressure of 800 to 1300 bar, and a uniform and stable nano oral emulsion of ganoderma spore oil is obtained. "A nano ganoderma spore oil and its production process and application" (publication number CN103393590A) discloses a method for preparing nano ganoderma spore oil by high-pressure homogenization, and the method needs to be homogenized 3 times under the condition of a homogenization pressure of 150 to 200 MPa, each time for 30 minutes. Although nanoemulsions with smaller particle sizes can be produced, the process requires higher homogenization pressure and time, which significantly increases the temperature of the emulsion system. The emulsion itself is a thermodynamically unstable system. Excessively high temperature leads to uneven emulsion particles and Oswald ripening, causing the distribution of emulsion particles to further widen. During long-term storage, oil and water stratification, flocculation, and rancidity are prone to occur, which in turn produces a fishy smell and a greasy feeling, seriously affecting the taste of the product. Summary of the invention

[0005] The purpose of the present invention is to overcome the taste problems of greasy and fishy smells in the conventional high-pressure preparation of oral liquid of ganoderma lucidum spore oil. In view of the deficiencies of the prior art, an oral liquid of ganoderma lucidum spore oil with improved taste and a preparation method thereof are provided. The oral liquid prepared by the preparation method has stable properties, good uniformity, is not prone to demulsification, stratification, flocculation, and has good taste, thereby improving consumer acceptance.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A method for preparing a ganoderma lucidum spore oil oral liquid with improved taste comprises the following steps:

[0008] A. Mixing antioxidant, ganoderma lucidum spore oil and emulsifier, stirring until completely dissolved and uniformly dissolved to form an oil phase;

[0009] B. Heat and keep water warm to form a water phase;

[0010] C. adding the oil phase to the water phase and stirring under high-speed shearing to prepare colostrum A;

[0011] D. adding a pH regulator to the colostrum A and performing ultrasonic treatment to prepare colostrum B;

[0012] E. homogenizing the colostrum B to obtain final milk;

[0013] F. Filling and sterilizing the final emulsion to obtain the oral liquid of Ganoderma lucidum spore oil with improved taste.

[0014] Preferably, in step C, the high-speed shearing speed is 6000-12000 rpm, the stirring time is 8-12 minutes, and the stirring temperature is 55-75°C.

[0015] Preferably, in step D, the power of ultrasonic treatment is 300-600W, and the time is 8-12 minutes.

[0016] Preferably, in step E, the homogenization pressure is 300 bar to 600 bar, and the homogenization times are 1 to 3 times.

[0017] Preferably, step A comprises: uniformly mixing the antioxidant and the ganoderma spore oil, then mixing with the emulsifier, heating and stirring until they are completely dissolved and uniform, to form the oil phase.

[0018] Antioxidants and emulsifiers can be well dissolved with the spore oil in the oil phase to form a uniform and stable oil phase.

[0019] Preferably, in step A, the temperature of heating and stirring is 35-75°C.

[0020] Preferably, in step B, the heating and insulation temperature is 55-75° C.; in step D, the pH value is adjusted to 6.5-8.0 by the pH adjuster; and in step F, the sterilization condition is that the F0 value is greater than 8.

[0021] Preferably, the Ganoderma lucidum spore oil is obtained by low-temperature carbon dioxide supercritical extraction of Ganoderma lucidum spores; the emulsifier includes one or more of lysophosphatidylcholine and polyoxyethylene xylitol monostearate; the antioxidant includes dilauryl thiodipropionate; and the pH adjuster includes hydrochloric acid or sodium hydroxide.

[0022] The selection of emulsifiers mainly considers whether it can stably prepare the emulsion without introducing odor or whether it can enhance the aroma of the entire product. For example, when egg yolk lecithin is used as an emulsifier, the oral liquid tastes more like egg, and when soybean lecithin is used as an emulsifier, the overall taste is more like soybean milk, which has a significant inhibitory effect on the unique aroma of Ganoderma lucidum spore oil. After a lot of exploration and experiments, it was unexpectedly discovered that lysophosphatidylcholine or polyoxyethylene xylitol monostearate as an emulsifier can enhance the aroma of Ganoderma lucidum spore oil.

[0023] The selection of antioxidants has a more obvious effect on the quality of oral liquids. Since the ganoderma lucidum spore oil emulsion system contains oil, water and oxygen at the same time, the final product is more likely to become rancid and have a peculiar smell when placed for a long time, compared with general oral liquids (oral liquids made of plant polysaccharides, minerals or vitamins), which affects the quality and taste of the oral liquid. The present invention selects dilauryl thiodipropionate as an antioxidant, which is a fat-soluble component compatible with the raw oil and fat, and is more conducive to the stability of the raw oil and fat.

[0024] The method for preparing the oral liquid of ganoderma spore oil with improved taste as described above comprises the following components in mass ratio: 5-25% of ganoderma spore oil, 0.5-20% of emulsifier, 0.01-0.05% of antioxidant, 0.001-0.01% of pH regulator, and the balance of water.

[0025] The main purpose of the pH adjuster is to adjust the pH value of the emulsion system. Depending on the concentration and type of the pH adjuster used and the size of the formulation, the pH can be adjusted to 6.5-8.0.

[0026] Preferably, the average particle size of the oral liquid of Ganoderma lucidum spore oil with improved taste is no more than 250 nm.

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] According to the preparation process of the oral liquid of ganoderma lucidum spore oil provided by the present invention, the product is more stable, and the colostrum is treated by ultrasound, which effectively reduces the homogenization pressure and the homogenization time, and the particle size of the emulsion is controlled below 250nm, so as to prevent the temperature of the emulsion from rising due to excessive pressure and too many homogenization times, and reduce the risk of oxidation of ganoderma lucidum spore oil and destruction of active substances. The oral liquid prepared by the preparation method has stable properties, good uniformity, is not easy to demulsify, stratify, flocculate, and has good taste, and improves the acceptability of consumers.

[0094] Effect Example 1

[0095] The average particle size, PDI, pH value, peroxide value, centrifugal stability and other indicators of the emulsions of Examples 1 to 6 and Comparative Examples 1, 2, and 3 were compared, and the results are shown in Table 1.

[0096] Table 1 Comparison of evaluation indicators of preparations

[0097]

[0098] As can be seen from Table 1, the oral liquid of ganoderma lucidum spore oil prepared by the present invention is homogenized under 300-600 bar, and the obtained liquid is uniform and stable, the particle size is below 250 nm, PDI < 0.2, and the centrifugal stability is good. As can be seen from the results of the comparative examples, comparative example 1 uses 700 bar pressure alone and homogenizes 3 times to prepare an emulsion with a particle size of less than 250 nm, but is subjected to high heat for a long time during the preparation process, resulting in an increase in the peroxide value, which affects the stability of the ganoderma lucidum spore oil in the emulsion; the emulsion particle size prepared by comparative example 2 using ultrasound 600W ultrasound alone is greater than 500 nm, and the emulsion stability is significantly worse than that of the embodiment, and the difference between comparative example 3 and the embodiment is that the preparation process is first homogenized, and then the emulsion is prepared by ultrasound, and the particle size of the obtained emulsion is increased by 53%, and the embodiment can obtain an emulsion with a smaller particle size and stable properties under the condition of reducing the number or pressure of high-pressure homogenization, which greatly reduces the oxidation of ganoderma lucidum spore oil and the risk of active substances being destroyed.
