Description

Technical Field

[0001] This invention relates to the field of deep processing technology of Huajuhong (Citrus reticulata), specifically to a Huajuhong flower hydrosol and its preparation method, and more particularly to a hydrosol product that can be taken orally or applied externally and its preparation process, prepared by steam distillation using fresh or dried Huajuhong flowers as raw materials. Background Technology

[0003] Huajuhong is a traditional Chinese medicine from Lingnan. Huajuhong flowers contain abundant volatile oils and flavonoids (such as naringin and hesperidin) and other active ingredients, which have the effects of relieving cough and phlegm, regulating qi and soothing the liver, antibacterial and anti-inflammatory, calming the nerves and relieving anxiety, and skin care and anti-oxidation.

[0004] Currently, most of the tangerine peel products on the market are made from dried flowers or slices, which have the following shortcomings: 1. The effective ingredients have a low dissolution rate, requiring long-term decoction or brewing, resulting in insufficient release of the effective ingredients; 2. It has a bitter taste, resulting in a poor drinking experience and limited consumer acceptance; 3. It is inconvenient to carry and drink, and cannot meet the modern people's demand for convenient and immediate consumption; 4. Traditional drying processes can easily lead to the loss of heat-sensitive volatile oil components, reducing the aroma and activity of the product.

[0005] Steam distillation is a common method for extracting volatile oils and aromatic waters from aromatic plants, which can retain the active ingredients in fresh raw materials to the maximum extent. Currently, there are no standardized hydrosol products and preparation processes for fresh or dried tangerine peel flowers on the market. Developing a hydrosol using fresh or dried tangerine peel flowers as raw materials and its preparation method has significant market value and application prospects. Summary of the Invention

[0007] 1. Purpose of the invention To address the shortcomings of existing technologies, this invention provides a hydrosol made from Citrus reticulata flowers and its preparation method, aiming to solve the problems of low dissolution rate of effective ingredients, poor taste, inconvenience of drinking, and easy loss of active ingredients in existing Citrus reticulata products. The invention provides a hydrosol product with a fresh aroma, high content of active ingredients, convenient drinking, and both oral and external applications.

[0008] 2. Technical Solution To achieve the above objectives, the present invention provides the following technical solution: (1) A kind of tangerine peel hydrosol The tangerine peel and safflower hydrosol comprises the following raw materials in parts by weight: - 10-30 parts fresh or dried tangerine blossoms - 30-90 parts purified water

[0009] Preferably, the fresh or dried tangerine blossoms are those from the Huazhou authentic producing area during their peak bloom or are dried flowers from the current year. The distillation process is completed within 48 hours after fresh harvesting to maximize the retention of volatile oils and active ingredients.

[0010] Preferably, the tangerine peel hydrosol contains naringin at a concentration ≥0.1 mg / mL and linalool, limonene, and other volatile oil components at a concentration ≥0.05 mg / mL.

[0011] (2) A hydrosol of tangerine peel and its preparation method The preparation method includes the following steps: S1. Raw material pretreatment: Remove impurities from fresh or dried tangerine blossoms, quickly rinse the surface dust with purified water, and drain the water to avoid prolonged soaking that could lead to loss of active ingredients; S2. Steam distillation extraction: Add the pretreated tangerine peel or dried flowers and purified water into a distillation apparatus in a certain proportion, heat to 100-110℃, and distill at a constant temperature for 60-120 minutes. Collect the initial distillate aromatic water obtained by condensation during the distillation process. S3. Filtration and sterilization: Filter the prepared liquid through a 0.22-0.45μm microporous membrane to remove impurities, and then perform pasteurization (80-85℃, keep warm for 15-30 minutes). S4. Aseptic filling: Cool the sterilized liquid to room temperature, fill it in an aseptic environment, and seal it to obtain the finished product.

[0012] 3. Beneficial effects Compared with the prior art, the present invention has the following beneficial effects: 1. High retention rate of active ingredients: This invention uses a direct steam distillation process for fresh or dried tangerine flowers, avoiding the loss of heat-sensitive volatile oil components during the drying process. The retention rate of active ingredients such as naringin, linalool, and limonene is significantly higher than that of traditional dried products, resulting in more significant effects in relieving cough and phlegm, regulating qi and calming the mind. 2. Excellent drinking experience: The hydrosol product of this invention has a fresh aroma and a sweet taste, without the bitterness of traditional tangerine peel products. It can be drunk directly without additional brewing, and can also be used as a throat spray or facial soothing spray, with a wide range of uses; 3. Stable process, suitable for industrial production: The preparation process parameters of this invention are clear and simple to operate, ensuring the content of effective ingredients and microbial stability of the product, making it suitable for large-scale production; 4. Good product stability: By adjusting the pH value and adding a small amount of excipients, the shelf life of the product is effectively extended, while retaining the natural active ingredients of Citrus reticulata safflower. There are no additional chemical additives, and the product is highly safe. Detailed Implementation

[0014] The present invention will be further described in detail below with reference to specific embodiments, but the implementation of the present invention is not limited thereto. Example

[0016] A hydrosol made from Citrus reticulata flowers and its preparation method include the following steps: 1. Raw material pretreatment: Harvest 20 portions of fresh or dried tangerine blossoms during their peak blooming period in the Huazhou production area, remove impurities, quickly rinse with purified water, and drain. 2. Steam distillation extraction: Add the processed fresh or dried tangerine blossoms and 80 parts of purified water into a distillation apparatus, heat to 100 to 110°C, and distill at a constant temperature for 60 to 120 minutes, then collect the distillate.

[0017] 3. Filtration and sterilization: Filtration is carried out using a 0.45μm microporous membrane, followed by pasteurization at 85℃ for 20 minutes; 4. Aseptic filling: After cooling to room temperature, aseptic filling is performed to obtain the finished product, Huajuhonghua hydrosol.

[0018] The hydrosol prepared in this embodiment has a naringin content of 0.18 mg / mL and a total volatile oil content of 0.09 mg / mL. It has a fresh aroma, a sweet taste, and no bitterness. It can be drunk directly or used as a throat spray.
