When the autumn breeze is shimmering and the morning frost is covered, it is the best time to taste hairy crabs.
The hairy crabs on the shores of Yangcheng Lake, the golden crab yellow and tender crab meat, make countless gourmets fascinated and longed.
Nowadays, the popularity of e-commerce platforms has made buying hairy crabs a breeze. Live video, beautiful display video, these vibrant, active hairy crabs seem to beckon to you. However, when you open the gorgeous gift box with anticipation, you find that the hairy crabs inside have lost their vitality.
Why is that?
Hairy crabs are a special creature that loves cold and humid environments. During the packing process, although the ice packs in the delivery box provide cooling, the effect of the ice packs gradually diminishes over time. The hairy crab's metabolism accelerates in a warm environment and the amount of oxygen required increases, but the closed environment in the express box leads to a shortage of oxygen, and soon the hairy crab loses its life.
According to the study, in the simulated transportation environment, the survival rate of hairy crabs reached 100% within 24 hours, but by 72 hours, the survival rate dropped to 60%. This means that if you buy hairy crabs and for some reason delay receiving them, you may be facing a hairy crab that is dying when you open the box. However, for diners, the most critical question is: can the hairy crab, which has died, be edible?
The fresh hairy crab of Yangcheng Lake is delicious, rich in crab yellow, and does not have any fishy smell. But once he died, the microorganisms inside the crab began to multiply wildly, and soon, the body of the hairy crab would be contaminated with bacteria and no longer suitable for consumption.
More importantly, hairy crabs have a large number of amino acids in their bodies, and after death, these amino acids will be converted into some harmful substances, such as cadaverine, putrescine and so on. These substances not only affect the taste, but are more likely to cause harm to the human body. So, since you can't eat it, can you consider refrigerating or freezing it?
Refrigeration or freezing can indeed keep hairy crabs fresh, but for too long, the flavor of the crabs will suffer. Moreover, ordinary household refrigerators are not absolutely sterile, and long-term storage of hairy crabs may cause cross-contamination with other foods.
Therefore, instead of buying hairy crabs from afar on e-commerce platforms, it is better to choose local fresh crabs. Whether it's hairy crabs from Yangcheng Lake or varieties from other places, in the end, the real charm lies in the freshness.
Therefore, when the autumn breeze blows again, you may cherish the beauty around you more, and taste the freshest and most authentic hairy crab with your relatives and friends, which is the real enjoyment of life.
