2. The main reasons for the shrinkage of sea cucumbers
According to the analysis of food science experts and cooking experts, the shrinkage of sea cucumbers after cooking is mainly related to the following factors:
| Reason | Specific performance | degree of influence |
|---|---|---|
| water loss | High temperatures cause cellular water to evaporate | ★★★★★ |
| Collagen shrinkage | Protein denatures when exposed to heat | ★★★★ |
| Improper preprocessing | Not fully soaked | ★★★ |
| Variety differences | Different varieties have different shrinkage rates | ★★ |
3. Measured data on sea cucumber shrinkage
A team of professional chefs conducted cooking experiments on different varieties of sea cucumbers and recorded the following data:
| Sea cucumber varieties | Original weight (g) | Weight after cooking (g) | Shrinkage |
|---|---|---|---|
| Liao ginseng | 50 | 32 | 36% |
| Guandong ginseng | 45 | 28 | 38% |
| Plum Blossom Ginseng | 60 | 42 | 30% |
| Topaz Ginseng | 55 | 40 | 27% |
4. How to reduce the shrinkage of sea cucumbers when cooked
According to professional advice, you can maximize the volume and nutrition of sea cucumbers through the following methods:
1.Fully soaked: Dried sea cucumber needs to be refrigerated and soaked in purified water for 2-3 days, and the water should be changed every 8 hours.
2.Control the heat: After boiling, turn to low heat and simmer to avoid violent boiling
3.Add excipients: Add a small amount of edible alkali or baking soda to maintain elasticity
4.Choose fresh: The shrinkage rate of fresh sea cucumber is about 15% lower than that of dried sea cucumber.
5.rapid cooling: Immediately after cooking, add ice water to set the shape
5. Excerpts of hotly discussed opinions among netizens
| opinion type | Representative comments | Number of likes |
|---|---|---|
| Surprise | “I was so scared when I cooked sea cucumber for the first time, thinking I had bought a fake!” | 23,000 |
| Science popularizer | "This is a normal phenomenon of protein denaturation, just like steak shrinks when cooked" | 31,000 |
| empiricist | "Old fishermen all know that sea cucumbers need to be boiled three times and soaked three times to maintain their shape." | 18,000 |
| humorist | "It turns out that sea cucumbers can also 'shrink and lose weight'" | 45,000 |
6. Scientific analysis of sea cucumber nutritional value
Although cooking will cause the sea cucumber to shrink in size, its core nutrients will not be lost:
| Nutritional information | Content (per 100g) | heat resistance |
|---|---|---|
| protein | 16.5g | Partially denatured but not lost at high temperatures |
| Sea cucumber saponins | 0.3g | High temperature resistance |
| Mucopolysaccharides | 6.2g | partially soluble in water |
| trace elements | Calcium, iron, zinc, etc. | fully reserved |
From the above analysis, we can see that it is a normal physical phenomenon for sea cucumbers to shrink in size after cooking. As long as you master the correct processing methods, you can still enjoy the rich nutrition of sea cucumbers. It is recommended that consumers refer to professional guidance when purchasing and cooking to avoid unnecessary worries caused by ignorance of characteristics.
