Soft-shelled turtle, as a traditional nourishment, has always been very popular in the market. However, with the increasing concern about food safety and health, the difference between wild soft-shelled turtle and farmed soft-shelled turtle has become the focus of consumer concern.
This article will make a comprehensive comparison between wild soft-shelled turtle and farmed soft-shelled turtle from multiple perspectives, and ** their identification methods and nutritional value in the market.
1. The difference between wild soft-shelled turtle and farmed soft-shelled turtle
1.Growing Environment:
Wild soft-shelled turtles grow in natural environments, such as rivers, lakes, reservoirs, and other waters. They grow freely in an environment with clear water and abundant food, undergoing a long period of natural selection and adaptation.
In contrast, farmed soft-shelled turtles are grown in an artificial simulated environment, such as ponds, greenhouses, etc. These breeding environments usually artificially regulate water quality, temperature, feed, etc., to ensure the growth rate and quality of soft-shelled turtles.
2.Growth Cycle:
Wild soft-shelled turtles have a long growth cycle, generally taking 3-5 years to reach maturity. This is because they forage for themselves in their natural environment, their food is unstable, and they are exposed to a variety of natural risks.
The growth cycle of farmed soft-shelled turtle is relatively short, usually reaching the market size in about 1-2 years. This is because the breeding environment has sufficient feed and stable water quality, which is conducive to the rapid growth of soft-shelled turtles.
3.Exterior features:
There are also certain differences in appearance between wild soft-shelled turtles and farmed soft-shelled turtles. In general, the dorsal shell of wild soft-shelled turtles is grayish-black or yellowish-brown, and the texture is hard and smooth; The abdomen is lighter in color and yellowish-white or off-white.
The color of the back shell of the farmed soft-shelled turtle may be relatively simple, mainly gray-black. The abdomen is darker in color and sometimes black or dark gray. In addition, wild soft-shelled turtles are relatively slender and have firm muscles; The farmed soft-shelled turtle is relatively fat.
4.Taste and quality:
Due to the differences in growth environment and growth cycle, wild soft-shelled turtles and farmed soft-shelled turtles are also different in taste and quality. The meat of wild soft-shelled turtle is delicate and delicious, and has high nutritional value and medicinal value.
The meat quality of farmed soft-shelled turtles is relatively soft, and the taste is slightly inferior to that of wild soft-shelled turtles. However, with the continuous progress of breeding technology, some high-quality farmed soft-shelled turtles have approached or even surpassed wild soft-shelled turtles in taste and quality.
2. How to identify wild soft-shelled turtles and farmed soft-shelled turtles in the market
1.Observe the appearance:
As mentioned above, there are certain differences in appearance between wild soft-shelled turtles and farmed soft-shelled turtles. Consumers can make preliminary identification by observing the color, texture, belly color and body shape of the shell of the soft-shelled turtle.
2.Ask**:
When purchasing, you can ask the seller for the soft-shelled turtle**. If the seller can provide detailed information such as the location and time of fishing, then these soft-shelled turtles may be wild soft-shelled turtles; If the seller is providing information about the farm, then these soft-shelled turtles may be farmed soft-shelled turtles. It should be noted that some unscrupulous merchants may use farmed soft-shelled turtles to pretend to be wild soft-shelled turtles for sale, so consumers must be cautious when purchasing.
3.Check the certificate:
Some regular sellers will provide relevant certificates or labels to prove the quality and ** of soft-shelled turtles. For example, wild soft-shelled turtles may provide fishing licenses, inspection and quarantine certificates, etc.; Farmed soft-shelled turtles may provide breeding certificates, feed certificates, etc. Consumers can ask the seller to provide these certificates or labels for verification at the time of purchase.
3. Comparison of the nutritional value of wild soft-shelled turtle and farmed soft-shelled turtle
From the perspective of nutritional value, both wild soft-shelled turtles and farmed soft-shelled turtles are rich in nutrients such as protein, unsaturated fatty acids, amino acids, vitamins and trace elements. These nutrients have a positive effect on improving human immunity, promoting metabolism, and delaying aging.
However, due to the long growth cycle, abundant food and self-foraging of wild soft-shelled turtles, their meat is firmer, more delicious, and the content and proportion of nutrients may be more reasonable.
In contrast, the feed of farmed soft-shelled turtles** is relatively simple, and the growth cycle is shorter, so it may be slightly inferior to wild soft-shelled turtles in terms of nutrient content and proportion. However, with the continuous progress of breeding technology and the continuous optimization of feed formula, some high-quality farmed soft-shelled turtles have approached wild soft-shelled turtles in terms of nutritional value.
Consumers should choose according to their own needs and budget when purchasing, and pay attention to distinguishing the quality and ** of soft-shelled turtles. At the same time, in order to protect natural resources and the ecological environment, we should also promote the concept of rational consumption and avoid overfishing and indiscriminate consumption of wild animals.
