There can be learned. buy canned fruit "three step" walk allows you to easily buy high quality canned fruit.
Step 1: watch the packaging. Observe whether the outer packaging is neat and clean, whether the handwriting is clearly printed, and whether the label is complete and formal. If the printing quality is poor, the handwriting is blurred, the marked content is incomplete, and the production date is not stamped, it is likely to be a counterfeit product.
Two steps: check the endoplasm. For products packaged in glass bottles, check the color, state and smell of the contents, and observe whether the block shape of the contents is complete, free of foreign matter and turbidity. Good quality of the canned contents of raw food inherent in the natural, fresh color, block shape, size is basically the same, complete not loose. Fruit color should not occur browning, sugar clear and transparent, in addition to allow a very slight pulp debris precipitation, should be no impurities, no suspended solids. For products packaged in metal cans, the surface should be clean and free of rust spots, the bottom and cover should be slightly recessed, the weld and bottom curling should be free of damage, and the door should be sealed tightly without deformation. If it is found that the inner and outer walls of the metal tank or the tank cover has rust caused by corrosion, do not buy it.
Three steps: prevent "fat listening" and "missing listening". The iron center of the bottom and lid of normal fruit cans is flat or slightly concave, without leakage. When contaminated by microorganisms, canned fruit will often appear "fat to listen", that is, the bottom of the can and the lid of the iron center part of the bulge, which is the bacteria in the tank to produce gas, resulting in the tank pressure is greater than the air pressure. "Leak-out" means a can with a leak in the seal failure. The products packed in metal cans are collided by objects during transportation, and the outer wall often collapsing, causing air to enter easily and the contents to deteriorate.
