Second, when buying dry sea cucumber, choose the dry wrinkled one (naturally dried). Some unscrupulous traders usually add a lot of sugar, gum and even alum to increase the weight of sea cucumber during processing. Although the sea cucumber processed in this way does not meet the quality standards, it is extremely full and beautiful in color, which has brought great deception to consumers.
In addition, it should be noted that some sea cucumbers are dyed, and the color is very dark in terms of performance. The opening of sea cucumber is generally black, and the sea cucumber tendons inside are all dyed black. It can be seen that those manufacturers who are carried away by greed have already reached the point of forgetting profits.
Third, when you finally buy dry sea cucumber, don't blindly pursue cheap products, but make a comprehensive comparison according to the bubble rate in dry sea cucumber. A Jin of good dry sea cucumber can usually produce 10 Jin of water-borne sea cucumbers, and the foaming rate of some high-quality sea cucumbers is higher. For example, a kilo of pure and light dry sea cucumber in Yu Lang Island can be soaked in 15- 17 kg of sea cucumber; And a catty of inferior dried ginseng, after being mixed with water, does not exceed 5 jins, and even it is so broken that it cannot be eaten at all.
