Method 1: Look at the color.
There is a great difference in color between sausages with good quality and sausages with poor quality. High-quality sausages are not too dark in color, and sausages with too dark color may have too many seasonings such as soy sauce and taste worse.
Method 2: Look at the casing thickness.
The thinner the sausage skin, the better. Sausages taste crisp after steaming. If the skin is thicker, it will taste harder and taste worse. Look at the skin thickness of the sausage mouth and knead it with your hands.
Method 3: Look at the status.
Sausages are easy to store in dry state and have good taste. If the sausage is not completely dried by moisture, it may increase its weight and is not suitable for purchase.
How to preserve sausages:
1. Hanging preservation method
After the sausage is completely air-dried, it can be hung in a cool, dry and sun-proof place. But when it gets hot, we should always check whether the sausages are dry enough. If the sausage surface is oily and sticky, it means that the weather is too hot and the sausage must be kept in the refrigerator. This method is suitable for short-term preservation and only suitable for use in the south. If used in the north, sausages will become dry wood.
Put it in the refrigerator.
After vacuum packaging sausage, put it in refrigerator to freeze or refrigerate. If it is cold, it can generally be preserved for about 3 months, and it can be preserved for up to one year, and there is no need to worry about the impact of climate change on the quality of sausages.
