Introduction

If the cooking time is too short, such as less than 10 minutes, the shell may turn red easily, but the center of the shrimp meat might not be fully cooked, especially when the shrimp tail is tightly curled, where blood veins may remain. At this point, the texture may be undercooked and the fishy odor noticeable, potentially leading to foodborne illnesses due to insufficient elimination of parasites and bacteria, causing symptoms such as abdominal pain and diarrhea.

The cooking time for crawfish should ensure the meat is fully cooked and pathogens are eliminated. It is recommended to boil them for 10-15 minutes, although the exact time may vary.

If the cooking time is too short, such as less than 10 minutes, although the shell may turn red easily, the center of the crawfish meat might not be fully cooked. Especially when the tail is tightly curled, there may be residual blood inside. At this point, the texture will be undercooked and the fishy odor obvious, and it may also cause foodborne diseases due to insufficient elimination of parasites and bacteria, leading to symptoms such as abdominal pain and diarrhea.

When cooked for 10-15 minutes, high temperatures can penetrate the shell, fully coagulate and whiten the meat, and adequately destroy harmful microorganisms. Within this timeframe, the crawfish meat can maintain a tender texture while ensuring food safety. Please note that if the crawfish are particularly large, the cooking time can be appropriately extended up to 15 minutes to ensure the meat is thoroughly cooked from the outside in; smaller crawfish may be fully cooked in about 10 minutes.

Before cooking, thoroughly scrub the crawfish body, remove the intestinal tract, and ensure the water in the pot completely covers the crawfish to ensure even heating. When consuming, pay attention to moderate intake. In daily diets, it is recommended to maintain a balanced dietary structure and diversify food intake to help maintain health.

Can the yellow substance in the head of a crawfish be eaten?

If the crawfish come from正规渠道 (legitimate sources), are raised in environments that meet safety standards, and are not contaminated, and if the head's sand sack and other dirty parts such as the intestinal tract have been removed before cooking, then after being thoroughly cooked at high temperatures, the yellow substance in the head mainly consists of roe and hepatopancreas, which can be consumed in small quantities as they contain certain proteins and nutrients. However, consumption should be controlled, as excessive intake might increase digestive burden due to the relatively high fat content in the hepatopancreas.

Can Semisulcospira promote digestion?

Under normal circumstances, freshwater snails do not have a direct effect on promoting digestion. When consumed in moderation as a food source, they can provide nutritional benefits, but extra attention should be paid to preparation methods and consumption quantity. In daily life, to aid digestion, it is recommended to eat more vegetables and fruits rich in dietary fiber, maintain a light diet, and follow regular作息 (作息 should be translated as "lifestyle habits" or "daily routine" depending on context; please confirm). Relying solely on freshwater snails has limited effectiveness; scientific dietary habits are the key to improving digestion.

Can Semisulcospira (溪螺) clean the intestines?

Under normal circumstances, freshwater snails can aid digestion to some extent, but they cannot directly cleanse the intestines. It is important to ensure thorough preparation and moderate consumption. Freshwater snails live in complex environments and may carry parasites or bacteria; therefore, they must be thoroughly cleaned and cooked at high temperatures to avoid foodborne risks. In daily life, maintaining intestinal health primarily relies on adequate intake of dietary fiber.

Can Semisulcospira reduce cholesterol?

Under normal circumstances, river snails cannot lower cholesterol levels, and excessive consumption may be detrimental to cholesterol control. Therefore, attention should be paid to thorough preparation and appropriate portion sizes. River snails grow in complex environments and may carry parasites or bacteria; they must be thoroughly cleaned and cooked at high temperatures to avoid foodborne risks. In daily life, controlling or reducing cholesterol requires limiting the intake of high-cholesterol and high-fat foods.
