Nowadays, many people hold misconceptions about food. For instance, some believe that the darker the color of black fungus, the higher its nutritional value. But that's not actually the case! It's precisely this mindset that allows unscrupulous vendors to tamper with the fungus. So let's explore the nutritional value of black fungus and why darker isn't necessarily better. Let's dive in!
Nutritional Value of Black Fungus
Black fungus is rich in protein, comparable to animal-based foods, earning it the reputation as "vegetarian meat." It also boasts exceptionally high vitamin E content, making it excellent for skin brightening.Most importantly, they boast the highest iron content. While spinach, lean meat, and animal liver are commonly recognized as rich iron sources, black fungus actually contains over 20 times more iron than spinach and more than 7 times that of pork liver. This makes it an excellent food source for beautifying the complexion, replenishing blood, and preventing iron-deficiency anemia.
Black fungus is rich in cellulose and a unique plant collagen. These substances promote gastrointestinal motility, prevent constipation, facilitate the timely elimination of toxic substances in stool, and possess certain dissolving properties for endogenous foreign bodies like gallstones and kidney stones.For individuals experiencing initial episodes of cholecystitis or gallstones, consuming black fungus 1-2 times daily can alleviate symptoms like pain and nausea within 2-5 days.
Black fungus contains vitamin K and abundant minerals like calcium and magnesium, which help reduce blood clots and prevent thrombosis. It plays a role in preventing and treating atherosclerosis and coronary heart disease.
Blacker doesn't necessarily mean more nutritious
Some unscrupulous merchants deceive consumers by dyeing common earth fungus to pass it off as black fungus.Common wood ear mushrooms are artificially cultivated using sawdust or straw inoculated with wood ear fungus spores. They can also grow spontaneously in damp environments. These mushrooms have little nutritional value and are very low-cost—the farm-gate price for a pound is around ten yuan. However, after dyeing, they are transformed into "nutrient-rich" black fungus, selling for nearly fifty to sixty yuan per pound.Fraudsters typically pour the common wood ear mushrooms into an iron pot filled with hot water, add a certain amount of ink, and thus transform the originally yellowish-brown mushrooms into black "black fungus." Currently, this counterfeit black fungus is widely sold online, and consumers should learn how to identify it.
Additionally, due to black fungus's high absorbency, it readily soaks up various substances including sugars and salts. Some unscrupulous vendors even soak it in magnesium sulfate to increase weight, making a pound of black fungus "fatten" by two or three pounds.However, as a chemical compound, magnesium sulfate is also used as a laxative and is strictly prohibited in food additives.
Darker isn't necessarily better for black fungus. Consumers can distinguish authenticity by examining color.Genuine black fungus features a dark brown upper surface and a grayish-white underside, while earth fungus is yellowish-brown. Sulfate-treated fungus appears uniformly dark brown on both sides. Additionally, authentic black fungus possesses a natural, clean aroma, whereas adulterated varieties emit an ink-like stench.When "processed" "black fungus" is soaked in water, the liquid quickly turns jet black. Furthermore, genuine fungus has a pleasant, fragrant taste when chewed, whereas magnesium sulfate-treated fungus tastes bitter and astringent, making it difficult to swallow.
A word of caution: fresh fungus is toxic, so never consume it raw.Fresh wood ear mushrooms contain a photosensitive substance called porphyrin. This can cause dermatitis, rashes, and other conditions, as well as trigger allergic reactions in respiratory mucous membranes, leading to symptoms like breathing difficulties.
