It's inside the lean pork. From the picture, it looks like it's a lump, or maybe it's a lymph node, so next time when you buy pork, be careful. Here's how to pick quality pork.

The way to determine whether pork is good or bad:

Look: color

The color of pork is an important criterion for identifying a piece of pork that is good or bad. Good pork color is light red or bright red, uniform color, muscle gloss, fat white. Unsafe pork, often dull meat color, fat lack of luster. For example, watered-down pork is much lighter in color than fresh meat.

The color of fresh meat is bright red, and as the amount of water injection increases, the meat becomes lighter and whiter. So, based on the color of the meat, we are able to roughly determine the water injection of the meat.

But pork with "lean meat extract" is especially bright red and shiny. If the lean part of the meat is too red, the quality of the meat may not be normal.

Smell: Fragrance

Fresh pork, with the inherent smell of freshness, free of chemicals and antibiotics, even if it is boiled in plain water, without any seasoning are no fishy smell, taste soft and fresh. Pork that is not fresh usually has an ammonia or acidic odor.

Touch

Good pork will have a good sense of touch, if the surface of the muscle is slightly dry or slightly wet, and touch with the hand is not sticky, good elasticity, finger pressure depression immediately recovered, it is an excellent pig, not fresh pork, dry skin, sticky cut surface, poor elasticity.

Observation: shape

Fresh meat will rarely have water or blood oozing out, the surface does not have any spots. And unclean pork, the epidermis has red spots or blood spots, if the lean meat with oval, milky white blisters, like meat sandwiched between grains of rice, this kind of meat is called "rice heart meat", eat will get tapeworm disease, must pay attention to.
