Counterfeit Food_Common Counterfeit Food Identification Methods

In recent years, people are more and more concerned about food safety, and here we provide consumers with several ways to identify fake and shoddy food to avoid being fooled.

First, coloring food: such as coloring "yellow fish", coloring "three yellow chicken", coloring "hairy beans", coloring "chili powder "and so on. These foods have abnormal sensory color, easy to fade. In general, the ice and the inside of the foam crate that touched the dyed "yellow fish" during sales were dyed light yellow; the soup of the dyed "three yellow chicken" was light yellow; the solid dyed foods such as the dyed "chili powder" were dyed light yellow after being soaked in hot water. Food soaked in hot water will generally fade.

Second, alkali hair products: such as alkali hair shrimp, alkali hair cuttlefish. The appearance of these foods full, loose tissue, feel slippery, high water rate, easy to burn paste, eaten with alkali flavor.

Third, fertilizer bean sprouts: the use of chemical fertilizer to promote the growth of bean sprouts short or rootless, blue. If you break the bean sprouts, there will be water coming out of the section, and some have the smell of fertilizer.

Fourth, watered beef: beef injection: beef injection after the appearance alone, but instead of a feeling of tenderness, but a closer look, you will find that the surface of the beef with water bubbling, with dry paper on it, will soon be wet.

Fifth, adulterated vegetable oil: high quality vegetable oil at room temperature, pure texture, clarification and transparency, and adulterated inferior oil was yellowish-brown, dark, and visible turbid impurities.

Six, adulterated fungus: adulterated with salt and alum and other fungus weight increase, fragile, poor water absorption after soaking in water.

Seven, oil tofu water: water filled oil tofu greasy feeling poor, rough surface. Some discoloration, the edge of the color white, with a twist of the hand, there is water dripping. High-quality oil tofu twisted soon after the original shape, water-filled oil tofu twisted easily rot, can not restore the original shape.

Eight, fresh fish irrigation: manifested in the belly. If the water in the abdomen, you can lift the fish, you will find the fish below the anus on both sides out of the sagging, with a small finger inserted into the anus to rotate two times, the finger out, the water will flow out immediately.

Nine, whether the oil is adulterated: look at the color. The color is light red or red with yellow for the genuine. Machine-pressed sesame oil is lighter than the color of small milled sesame oil, such as the color of black red or deep yellow, it may be mixed into the cottonseed oil or rapeseed oil. Smell the aroma. Small milled sesame oil genuine aroma mellow, rich, unique, such as mixed into peanut oil, soybean oil or canola oil, aroma deterioration, and with peanuts, beans and other odors. Look at the shape. With chopsticks dipped in oil, a drop in cool water above, a good fragrance oil was thin colorless transparent large oil flowers, about 1 cm in diameter, if cottonseed oil, is thicker, smaller yellow oil flowers, the difference is obvious. Other oil drops in cool water above, the shape is not the same as the fragrance oil. Look at the changes. Fragrance oil is clear and transparent in daylight, such as mixed into the cool water, opaque in the light; if mixed with too much water, fragrance oil will be layered and easy to precipitate deterioration.
