First of all, according to the market situation of sea cucumber mentioned in Reference 4, the price of sea cucumber varies with varieties, producing areas, processing methods and other factors. Generally speaking, the price of light dry sea cucumber is higher, usually several thousand yuan per catty. For example, the price of dry sea cucumber mentioned in Reference 8 is three or four thousand yuan per catty, while the price of dry sea cucumber with good quality mentioned in Reference 10 is not less than 3,000 yuan. Therefore, the price of a kilo of light dry sea cucumber in 800 yuan is relatively low, which may arouse consumers' doubts.
Secondly, Reference 4 mentions that there are some irregular behaviors in the sea cucumber market, such as using salted sea cucumber as light dry sea cucumber, or adding salt and sugar to increase the weight to reduce the cost. These behaviors may cause the actual value of sea cucumber to be inconsistent with its price tag.
Finally, it is mentioned in data 7 that at the current price of fresh sea cucumbers, 1.350 yuan is definitely not enough to buy real pure light dry sea cucumber, because this price is far from enough even for the cost of sea cucumbers. This shows that if the price of sea cucumber is far below the market average, its authenticity is doubtful.
To sum up, although it is impossible to directly determine the authenticity of 800 yuan's pale dry sea cucumber, according to market conditions and expert opinions, the price may be on the low side. Consumers should be vigilant when buying, and carefully distinguish the seller's reputation from the authenticity of the product. Consumers are advised to choose reputable merchants when purchasing sea cucumbers, and provide corresponding quality certificates, such as test reports.
