But raw fungus soaked for too long, whether or not it is spoiled are not allowed to eat. Wooden fungus soaked for a long time will produce toxins, in general, the fungus soaking time more than 8 hours, which contains bacteria has been far more than the original number of bacteria, this time should consider to avoid eating this fungus. Under normal circumstances, with room temperature water soaking, more than 1 hour can be completed, of course, if the soaking forgotten, a few days later to think of eating, that is extremely unfavorable to health, good not to eat, in order to avoid poisoning.
Tender taste, special flavor, is a nutritious famous edible fungi. 100 grams of dried black fungus in water 10.9 grams, 10.6 grams of protein, 0.2 grams of fat, 65.5 grams of carbohydrates, calories 306 kcal, 7.0 grams of crude fiber, 5.8 grams of ash, 357 milligrams of calcium, 201 milligrams of phosphorus, 185 milligrams of iron, carotene 0.03 milligrams, Thiamine 0.15 mg, riboflavin 0.55 mg, niacin 2.7 mg and multiple minerals. The protein of water fungus is very low, containing 1.5 grams in 100 grams. It has the effect of benefiting qi, filling hunger, lightening the body and strengthening the intellect, stopping bleeding and relieving pain, tonifying blood and activating blood. Rich in polysaccharide colloid, has a good role in clearing and sliding, is an important health food for mine workers, textile workers. Also has a certain anti-cancer and treatment of cardiovascular disease function and so on.
The efficacy of fungus
1, anticoagulant effect
300% fungus decoction 1ml/100g gavage, 20d, experimental results show that the fungus can prolong the white clay part of the thromboplastin time of 12.06s, to improve the activity of plasma antithrombin Ⅲ, with a significant anticoagulant effect. Black fungus polysaccharide 50mg/kg to mice static injection, intraperitoneal injection, gavage, have obvious anticoagulant effect; in vitro experiments, black fungus polysaccharide also has a strong anticoagulant activity.
2, anti-platelet aggregation
The phosphate buffer salt aqueous extract of Auricularia auriculae significantly inhibited ADP-induced platelet aggregation in vitro and blocked the release of 5-hydroxytryptamine from ADP-activated platelets below 16 μmol/L, and the active component of Auricularia auriculae's anti-platelet effect was water-soluble. Reduced platelet function was observed in humans within 3 h after oral administration of 70 g of Auricularia nigra and lasted for 24 h. Mycelial acid extracts of Auricularia nigra in vivo (10 g/kg by static injection or 10 g/kg by gavage in rats for 15 consecutive days) and in vitro (25mg/ml, 50mg/ml, and 100mg (mycelium)/ml) significantly inhibited platelet aggregation induced by ADP in rats. Alcoholic extract 5g/kg,7g/kg by gavage,***15d,can significantly shorten the electrophoresis time of erythrocytes. The results of intraperitoneal injection test of Black Cohosh Acid Heteropolysaccharide in mice showed that the polysaccharide has the effect of promoting leukocyte increase, anticoagulation and platelet lowering, and its activity increases as the molecular weight of the polysaccharide and the content of glucuronic acid decreases, i.e., the bioactivity is dependent on the solubility of the polysaccharide in water
