Sun drying is one of the oldest and most straightforward methods of dehydration. Grape seeds are spread out in a thin layer on drying racks or trays and exposed to direct sunlight. The heat and UV rays from the sun help to evaporate the moisture content in the seeds, concentrating the bioactive compounds in the extract. However, this method is highly dependent on weather conditions and can be time-consuming, taking several days to weeks to achieve the desired level of dryness.

2.2 Air Drying

Air drying involves placing the grape seeds in a well-ventilated area, allowing the natural movement of air to remove moisture. This method is more controlled than sun drying, as it can be done indoors or in a greenhouse, reducing the reliance on weather conditions. However, it still requires a significant amount of time and can be affected by humidity levels, which may slow down the drying process.

2.3 Oven Drying

Oven drying is a more accelerated traditional method that uses heat to evaporate moisture from the grape seeds. The seeds are placed in an oven set at a low temperature, typically between 40-60°C, to avoid damaging the delicate bioactive compounds. This method is faster than sun or air drying but requires a consistent heat source and careful monitoring to prevent overheating.

2.4 Vacuum Drying

Vacuum drying is a more advanced traditional method that utilizes a vacuum chamber to create a low-pressure environment. The reduced pressure lowers the boiling point of water, allowing the moisture in the grape seeds to evaporate at lower temperatures. This method is more efficient than other traditional methods and helps to preserve the heat-sensitive compounds in the extract. However, it requires specialized equipment and can be more expensive to operate.

2.5 Lyophilization (Freeze Drying)

Lyophilization, or freeze drying, is a specialized traditional method that involves freezing the grape seeds and then removing the ice crystals under vacuum conditions. This process preserves the structure and bioactive compounds of the extract while removing moisture. Freeze drying is highly effective in maintaining the quality of the Grape Seed Extract but can be costly and time-consuming.

2.6 Conclusion
