Studies on the Mineral Content of Edible Mushrooms

식용 버섯류의 무기물 함량

To investigate on the trace element content of twelve edible mushrooms and Aloe arborescens, i. e., Lentinus edodes, Ganoderma lucidum (culturing in wood and soil), Tricholoma matsutake, Agaricus bisporus, Cyrophora esculenta, Auricularia auricula-Jude (produced in Korea and China), Sarcodon asparatus, Pleurotus ostreatus, Coriolus versicolor, Smilax rotundifolia and Aloe arborescerts were analyzed by Atomic absorption spectrometer. The obtained results were summerized as follows: 1. Potassium, sodium, magnesium and iron content for the most part samples were in large quantities, especially phosphorus content of those was highest ammount for the all samples. 2. Sodium content was much ammount in the Lentinus edodes (39mg) and Ganoderma lucidurn (20 mg), Culturing in wood and soil, while potassium was very high ammount in the Aloe arborescens and other samples. Mush ammount of magnesium as compared with others was Lentinus edodes (144mg), Ganoderma lucidurn (128mg), Aloe arborescerts (50mg) and pleurotus ostreatus (60mg). Phosphorus content of Ganoderma lucidurn, Lentinus edodes, Gyrophora esculenta, Auricularia polytricha and Agaricus bisporus was much ammount while iron content of all samples equality higher ammount. Sodium content of Aloe arborescens was not analyzed out for almost all, its potassium (82mg), magnesium (50mg) and iron (18rng) content comparatively higher quentity than others minerals and phosphorus volume (4.9mg) as compared with others, was conspicuously lower detect. 4. Cadimium and lead content of harmful metal element were detected on trace quentity for the most part samples 5. Organic acids of samples i.e., Legtinus edodes, Agaricus bisporus, Pleurotus ostreatus and Ganoderma lucidum were Citrate, Malate, Fumalate, Succinate, Oxalate, Acetate, Lactate, and Tartarate and Citrate, Malate and Fumarate contents were higher amount remarkbly than other organic acids. Tartarate content was trace amount.
