Abalone is a traditional precious food in China. It is one of the eight "seafood treasures" and is known as the "crown of seafood". It is an extremely precious seafood and has always enjoyed a high reputation in the international market. Moreover, abalone is rich in nutrition and has high medicinal value. It is recorded in Compendium of Materia Medica that abalone is flat in nature, sweet and salty in taste, can improve eyesight and tonify deficiency, clear away heat and nourish yin, nourish blood and nourish stomach, and tonify liver and kidney, so it is called "eyesight fish". According to the Pharmacopoeia, abalone shell, also known as Concha Haliotidis, is a famous Chinese herbal medicine, which can calm the liver and suppress yang, clear away heat and improve eyesight, and has therapeutic effects on headache, dizziness, blurred vision and green blindness. Huangdi Neijing records that abalone juice is used to treat blood dryness. Olaechea and others found that abalone is rich in protein, of which 30%~50% is collagen, which is much higher than other fish and shellfish. Li et al. successively determined and studied the nutritional components of Haliotis discus hannai. They all found that abalone is rich in protein, amino acids and mineral elements such as calcium, iron, zinc, selenium and magnesium, which play an important role in regulating acid-base balance and maintaining neuromuscular excitability. Yi Meihua et al. determined the nutritional components of sheep abalone and Haliotis diversicolor abalone. The research shows that abalone is rich in protein, low in fat, complete in amino acids and reasonable in proportion, and rich in vitamin E and trace elements. At the same time, abalone meat is rich in EPA, DHA, taurine, superoxide dismutase and other physiologically active substances. Peng Wenduo's research shows that Haliotis diversicolor contains all essential amino acids, and the content of taurine is almost equal to the total amount of free amino acids. Selenium (Se) content in the "fire of life" is much higher than that in common marine shellfish such as mussels, oysters and meretrix meretrix, and all ethnic groups are rich in vitamins and phospholipids.
