Golden Oyster mushrooms (Pleurotus citrinopileatus) are really quite stunning in clusters. This mushroom is spicy and bitter if cooked lightly. When cooked crispy they take on a strong nutty flavor that is quite delicious, and taste similar to cashews. This mushroom also thrives in higher temperatures compared to most other oyster mushrooms. Also the more light introduced, the more yellow-golden colour the caps will become. This mushrooms grows on a wide range of substrates including straw (wheat,rye,oat,rice, and barley straw), corn, coffee grounds, banana waste, most hardwoods and hardwood by-products like sawdust and paper, compost and much more. This mushroom is becoming more popular by chefs for it’s beautiful appearance and bold nutty flavor.
This can be grown on supplemented hardwood like one of our easy to inoculate grow kits.
Below is some of the science showing the health benefits gained from these mushrooms.
From this study - A Glycoprotein Extracted from Golden Oyster Mushroom Pleurotus citrinopileatus Exhibiting Growth Inhibitory Effect against U937 Leukemia Cells
"Mushrooms have become popular sources of natural antitumor, antiviral, antibacterial, antioxidative, and immunomodulatory agents. Golden oyster mushroom, Pleurotus citrinopileatus, is a common mushroom in oriental countries for human consumption. We isolated a functional protein (PCP-3A) from the fresh fruiting body of this mushroom. The isolation procedure included ammonium sulfate fractionation, DEAE-Sepharose CL-6B ion exchange chromatography, and Sephacryl S-300 gel filtration. Electrophoresis demonstrated that PCP-3A is a glycoprotein composed of 10 subunits, each approximately 45.0 kDa in size. In vitro cell study showed that PCP-3A at a concentration about 12.5 μg/mL inhibits the proliferation of human tumor cell line U937, in a time- dependent manner (24, 48, and 72 h). It failed to agglutinate rabbit and human erythrocytes, excluding its possibility from being a lectin. Flow cytometry revealed that it is capable of inhibiting the growth of U937 cells by way of S phase arrest and apoptotic induction. We suggest that PCP-3A is worth further investigating for antitumor use."
From this study - Nutritional and Medicinal Importance of Pleurotus Mushrooms: An Overview
Mushrooms of Pleurotus genus are popularly consumed all over the world due to their taste, flavor, high nutritional values, and some medicinal properties. Several species of this genus are rich in proteins with essential amino acids, physiologically important polysaccharides and essential fatty acids, dietary fibers, important minerals, and some vitamins. Because of these nutritional composition and the presence of some other active ingredients, these mushrooms have been reported to have anticancer, antihypercholesterolemic, antihypertensive, antidiabetic, antiobesity, hepatoprotective, antiaging, antimicrobial, antiallergic, and antioxidant activities. The high nutritional value and potential medicinal uses suggest that the Pleurotus mushrooms are important functional foods or nutraceuticals.
Proximate analysis of P. citrinopileatus revealed that it contained 22.10% protein, 1.32% crude lipid and 20.78% fibre. The mushroom was also found to contain variable amounts of minerals. The most predominant mineral found in the mushroom was Potassium with value of 2.28%. Copper, zinc and iron minerals were generally low with values from 0.0002, 0.0015 and 0.01%, respectively. Eight essential amino acids were detected namely Leucine>Valine> Threonine>Lysine>Phenylalanine>Isoleucine>Methionine>Tryptophan in decreasing order of abundance. Glutamic acid though non-essential was present in high proportion (3.07%). Vitamin B3 (Nicotinic acid), vitamin B5 (Pantothenic acid) and vitamin B2 (Riboflavin) were the most abundant vitamins in all samples analyzed. While vitamin B12 (Cyanocobalamin) and vitamin A (retinol) were the least with values of 0.3 and <10 μg/100 g, respectively. In conclusion, Pleurotus citrinopileatus mushroom can be an excellent source of micronutrients and antioxidants components.
