Harvesting and extraction methods are crucial components of the quality and production process of caviar, significantly impacting the final product's taste, texture, and overall quality. Caviar is primarily harvested from sturgeon fish, particularly species such as Beluga, Ossetra, and Sevruga. The harvesting process typically involves two main methods: traditional and modern. **Traditional Method:** In the traditional method, sturgeon fish are caught and then humanely slaughtered to extract the roe (eggs). This approach ensures that the roe is not damaged during the extraction process, preserving its delicate flavor and texture. Skilled artisans carefully remove the roe sacs from the fish, which are then rinsed with cold water to remove any impurities. The roe is then sorted by size and color to ensure uniformity. **Modern Method:** The modern method involves a more humane and sustainable approach known as "no-kill" or "caviar milking." In this process, the sturgeon is anesthetized, and the roe is extracted through a small incision without harming the fish. This technique allows for multiple harvests from the same fish over several years, enhancing sustainability and reducing the risk of overfishing. After extraction, the roe undergoes similar processing steps as in the traditional method. **Extraction Techniques:** Once the roe is extracted, it undergoes several key steps to become high-quality caviar. The roe is first salted to enhance flavor and act as a preservative. The salting process can vary depending on the desired flavor profile; some caviars are lightly salted while others are more heavily salted. Following salting, the caviar is rinsed again to remove excess salt and then dried to remove moisture. This step is critical as it prevents spoilage and maintains the caviar's freshness. **Quality Control:** Quality control measures are stringent throughout the harvesting and extraction process. Each batch of caviar is inspected for size, color, and texture to ensure consistency. Any defective or damaged eggs are removed to maintain the highest standards of quality. Additionally, caviar producers adhere to strict hygiene standards to prevent contamination and ensure the product's safety for consumption. In summary, the harvesting and extraction methods used in caviar production are designed to preserve the natural flavor and texture of the roe while ensuring sustainability and quality.
