Market relevance: Despite its drawbacks, solvent extraction is still widely used in the industry, especially in small - to medium - scale production. Many traditional companies that have been in the mulberry extract business for a long time may still rely on this method due to its relatively low cost and established infrastructure.

2.2. Maceration

Benefits:

• Simple and low - cost. Maceration is a straightforward process that involves soaking the mulberry material in a solvent for a certain period of time. It does not require complex equipment, making it accessible for small - scale producers or those starting out in the mulberry extract business.
• Minimal degradation of bioactive compounds. Since the process is relatively gentle compared to some other extraction methods, there is less likelihood of significant degradation of the valuable compounds present in the mulberry.

Drawbacks:

• Long extraction time. Maceration can be a time - consuming process, especially when compared to more modern extraction techniques. This can limit the productivity of a production facility and may not be suitable for large - scale, high - volume production.
• Lower extraction yield. The overall extraction efficiency of maceration is generally lower than some other methods. This means that a larger amount of raw material may be required to obtain the same amount of extract, which can increase the cost of raw materials.

Market relevance: Maceration is often used in the production of artisanal or high - quality, small - batch mulberry extract products. It is also favored by some small - scale producers who focus on the natural and traditional aspects of the extraction process and target niche markets where consumers are willing to pay a premium for products made using traditional methods.

3. Modern Extraction Technologies

3.1. Supercritical Fluid Extraction (SFE)

Benefits:

• Clean and green technology. Supercritical fluid extraction uses supercritical carbon dioxide as the extraction solvent. Carbon dioxide is non - toxic, non - flammable, and environmentally friendly. There are no solvent residues in the final product, which is a significant advantage, especially for applications in the food and pharmaceutical industries.
• Selective extraction. SFE can be highly selective in extracting specific bioactive compounds from mulberry. By adjusting the pressure and temperature, it is possible to target and extract particular compounds with high purity.
• High - quality extract. The extract obtained by SFE generally has a high quality, with good preservation of the bioactive compounds and their biological activities.

Drawbacks:

• High equipment cost. The equipment required for supercritical fluid extraction is complex and expensive. This includes high - pressure vessels, pumps, and control systems. The initial investment for setting up an SFE facility can be a significant barrier for small and medium - sized enterprises.
• Technical expertise required. Operating an SFE system requires specialized technical knowledge. Staff need to be trained to understand the principles of supercritical fluid extraction, as well as how to operate and maintain the equipment properly.

Market relevance: Supercritical fluid extraction is becoming increasingly popular in the high - end mulberry extract market. It is well - suited for companies that target the production of high - value, high - quality mulberry extract products for use in premium food supplements, pharmaceuticals, and cosmetics. Large - scale companies with the financial resources to invest in the equipment and training are more likely to adopt this technology.

3.2. Ultrasonic - Assisted Extraction (UAE)

Benefits:

• Enhanced extraction rate. Ultrasonic - assisted extraction uses ultrasonic waves to disrupt the cell walls of the mulberry material, which increases the mass transfer rate and improves the extraction efficiency. This can significantly reduce the extraction time compared to traditional methods such as maceration.
• Energy - efficient. UAE is relatively energy - efficient compared to some other extraction techniques. The ultrasonic energy is focused on the extraction process, reducing the overall energy consumption required for extraction.
• Versatile. It can be combined with other extraction methods, such as solvent extraction, to further improve the extraction performance. For example, ultrasonic waves can be used to enhance the solubility of target compounds in the solvent, resulting in a higher extraction yield.

Drawbacks:

• Scale - up challenges. While UAE works well on a small - scale laboratory basis, scaling up the process to industrial levels can present challenges. The distribution of ultrasonic energy needs to be carefully controlled to ensure consistent extraction across large volumes of mulberry material.
• Equipment wear and tear. The ultrasonic equipment is subject to wear and tear, especially when used for long - term or continuous extraction processes. This can lead to increased maintenance costs over time.

Market relevance: Ultrasonic - assisted extraction is gaining attention in the mulberry extract industry, particularly among medium - sized companies that are looking for ways to improve their extraction efficiency while still keeping costs relatively under control. It is also a promising technology for companies that are exploring new extraction methods to differentiate their products in the market.

3.3. Microwave - Assisted Extraction (MAE)

Benefits:

• Fast extraction. Microwave - assisted extraction uses microwaves to heat the mulberry material and the solvent, which leads to rapid heating and mass transfer. This can result in a very short extraction time, often several times faster than traditional extraction methods.
• Uniform heating. MAE provides more uniform heating compared to some other heating - based extraction methods. This helps to ensure that all parts of the mulberry material are heated evenly, which can improve the extraction efficiency and the quality of the extract.
• Energy - saving. Since the microwave heating is targeted and efficient, it can save energy compared to traditional heating methods. This can contribute to cost savings in the long - run for production facilities.

Drawbacks:

• Equipment limitations. The microwave - assisted extraction equipment has certain limitations in terms of the volume of material that can be processed at one time. This can be a drawback for large - scale production, where high - volume processing is required.
• Compound degradation. There is a risk of degradation of some bioactive compounds in the mulberry due to the intense heating during MAE. This needs to be carefully monitored and controlled to ensure the quality of the final extract.

Market relevance: Microwave - assisted extraction is suitable for companies that need to produce mulberry extract quickly and efficiently, such as those in the fast - moving consumer goods industry. It is also an option for companies that are looking to reduce their energy consumption and production time while maintaining a reasonable level of product quality.
