Introduction
The white membrane on lamb is edible. However, if the membrane appears dark in color, has an unpleasant odor, or the lamb itself has spoiled, such membrane may harbor bacteria and other harmful substances, and consuming it could lead to gastrointestinal discomfort. Additionally, undercooked white membrane is tough in texture and difficult to digest, potentially causing mechanical irritation to the digestive tract and resulting in symptoms such as bloating and abdominal pain.
Generally, the white membrane on mutton is edible, provided it is thoroughly cleaned and fully cooked. However, if it has spoiled or is contaminated with impurities, it should not be consumed. If in doubt, it is advisable to consult a healthcare professional beforehand. Detailed analysis is as follows:
The white membrane is rich in collagen. When fully cooked, it has a soft, chewy texture that enhances the flavor of dishes, and its nutrients can be normally digested and absorbed by the human body. Before consumption, any surface blood residue, lymphatic tissue, or other impurities should be removed to ensure cleanliness and prevent potential health risks from contaminants.
If the white membrane appears discolored (e.g., darkened) or emits an unpleasant odor, or if the mutton itself has spoiled, harmful bacteria and other dangerous substances may have developed. Consuming such membrane could lead to gastrointestinal discomfort. Additionally, undercooked membrane tends to be tough and difficult to digest, potentially causing mechanical irritation to the digestive tract and resulting in symptoms such as bloating and abdominal pain.
When preparing mutton, carefully clean any impurities from the white membrane and ensure it is thoroughly cooked. Avoid consuming spoiled mutton or its attached membranes altogether. If gastrointestinal symptoms occur after eating, seek medical attention promptly.
