如何用贞洁浆果提取物制作粉末

1. Introduction

Chastity berry extract has been garnering attention for its potential uses in various fields. Transforming it into powder form can enhance its usability, making it more convenient for storage, transportation, and application. This article will delve into the detailed process of creating powder from chastity berry extract, including the necessary methods, equipment, precautions, and its potential applications.

2. Methods of Extracting Chastity Berry Extract

Before making the powder, it is crucial to obtain the chastity berry extract. There are several common methods:

2.1. Solvent Extraction

Solvent selection: Ethanol or water can be used as solvents. Ethanol is often preferred as it can extract a wide range of active compounds effectively. However, if the final product is intended for applications where alcohol - free is required, water extraction may be more suitable.
Procedure:

1. Crush the chastity berries into a fine pulp. This can be done using a mortar and pestle or a mechanical grinder.
2. Add the solvent (ethanol or water) to the crushed berries in a suitable ratio. For example, a ratio of 1:5 (berries to solvent) may be used, but this can be adjusted depending on the quality and quantity of the berries.
3. Stir the mixture continuously for a certain period, usually several hours to ensure complete extraction. This can be done using a magnetic stirrer or by manual shaking at regular intervals.
4. Filter the mixture to separate the liquid extract from the solid residue. Filter paper or a Buchner funnel can be used for this purpose.

2.2. Supercritical Fluid Extraction

Principle: Supercritical fluid extraction uses a substance at its supercritical state (e.g., carbon dioxide) as the extracting agent. In the supercritical state, the fluid has properties between those of a liquid and a gas, which allows for efficient extraction of the active components from the chastity berries.
Process:

1. Place the chastity berries in the extraction chamber of the supercritical fluid extraction equipment.
2. Introduce the supercritical fluid (such as carbon dioxide) into the chamber at the appropriate pressure and temperature conditions. The pressure and temperature need to be carefully controlled to maintain the supercritical state. For carbon dioxide, typical pressure ranges are around 7 - 50 MPa and temperature around 31 - 80 °C.
3. Allow the supercritical fluid to interact with the berries for a specific time to extract the active compounds. This time may vary depending on the equipment and the quantity of berries but is usually in the range of 30 minutes to several hours.
4. After extraction, the supercritical fluid containing the extract is passed through a separator. By changing the pressure and temperature conditions in the separator, the extract is separated from the supercritical fluid, and the supercritical fluid can be recycled for further use.

3. Equipment Needed for Making Powder from Chastity Berry Extract

Evaporator:

• An evaporator is used to remove the solvent from the extract. Rotary evaporators are commonly used in laboratories. They work by reducing the pressure above the liquid, which lowers the boiling point of the solvent and allows it to be evaporated more easily. This helps in concentrating the extract.

• A spray drier is essential for converting the liquid extract into powder. It works by spraying the liquid into a hot drying chamber. The hot air rapidly dries the droplets, forming fine powder particles. Spray driers can be adjusted for different inlet and outlet temperatures, feed rates, and atomization pressures to optimize the powder formation process.

• If a more delicate powder with better preservation of active compounds is desired, a freeze - drier can be used. Freeze - drying involves freezing the extract first and then removing the water (or solvent) by sublimation under vacuum conditions. This method is gentler on the active components and can result in a powder with higher quality and stability.

• After drying, the resulting solid may need to be further ground into a fine powder. A grinder, such as a ball mill or a pulverizer, can be used for this purpose. The grinder should be able to produce a uniform and fine powder to ensure consistent quality.

4. Steps to Make Powder from Chastity Berry Extract

Concentration of the Extract:

1. If solvent extraction was used, the next step is to concentrate the extract. Use the evaporator to remove the solvent. Set the appropriate temperature and pressure according to the type of solvent and the nature of the extract. For example, when using ethanol as a solvent, a rotary evaporator can be set at a temperature of around 40 - 60 °C and a reduced pressure to efficiently evaporate the ethanol.
2. Continue the evaporation process until the extract reaches a suitable concentration. This can be determined by monitoring the volume or by measuring the density of the extract.

1. Spray Drying:
   • Prepare the spray drier by setting the inlet and outlet temperatures. For chastity berry extract, the inlet temperature can be set between 150 - 200 °C, and the outlet temperature should be maintained at around 80 - 100 °C. Adjust these temperatures based on the properties of the extract and the desired powder characteristics.
   • Feed the concentrated extract into the spray drier at a controlled rate. The feed rate should be optimized to ensure proper atomization and drying of the droplets. The atomization pressure can also be adjusted to control the size of the droplets, which in turn affects the final powder properties.
2. Freeze - Drying:
   • For freeze - drying, first, freeze the concentrated extract in a suitable container. This can be done in a freezer at a temperature below - 20 °C.
   • Place the frozen extract in the freeze - drier. Set the vacuum pressure and the heating temperature according to the equipment specifications. The vacuum pressure should be maintained at a low level (e.g., less than 100 mTorr), and the heating temperature should be carefully controlled to allow for sublimation of the solvent without overheating the extract.

1. Once the extract has been dried, whether by spray drying or freeze - drying, it may be in the form of small flakes or chunks. Use a grinder to break these down into a fine powder.
2. For ball mills, adjust the speed and the grinding time. A speed of around 100 - 300 rpm and a grinding time of 1 - 3 hours may be suitable, but this needs to be optimized based on the quantity and hardness of the dried product.

5. Precautions during the Production

Quality Control of Raw Materials:

• Ensure that the chastity berries used are of high quality. Check for any signs of contamination, such as mold or pesticide residues. Only use berries that are fresh and free from any harmful substances.
• Source the berries from reliable suppliers. This helps in maintaining the consistency of the extract and the final powder product.

• Regularly clean and maintain the equipment used in the extraction and powder - making process. For example, the evaporator should be cleaned to prevent the buildup of residue, which can affect its performance.
• Calibrate the equipment regularly to ensure accurate operation. This is especially important for devices such as the spray drier and the freeze - drier, where incorrect settings can lead to poor powder quality.

• When using solvents such as ethanol in the extraction process, ensure proper ventilation in the workspace. Ethanol is flammable, and the presence of vapors can pose a fire hazard.
• Handle the equipment carefully, especially when dealing with high - pressure (in supercritical fluid extraction) or high - temperature (in spray drying) operations. Wear appropriate protective gear, such as gloves and goggles.
