Mushrooms canned, nutrients

Investigations have focused on the content of polyphenoHcs, tannins, and related compounds in various foods and the influence on nutrient availabiHty and protein digestibiHty. It has been estabHshed that naturally occurring concentrations of polyphenoloxidase and polyphenols in products such as mushrooms can result in reduced iron bio availabiHty (75). Likewise, several studies have focused on decreased protein digestibiHty caused by the tannins of common beans and rapeseed (canola) (76—78). 

Of nutrient chelates in the human diet, oxalates and phytules arc Ihe most common. Oxalic acid, found principally in spinach, rhubarb leaves, beet leaves, some fruits, and mushrooms, is u primary chelator of calcium. Oxalate present in pineapple, kiwifmil, and possibly in other foods, occurs as calcium oxalale. CaCiOj. This compound is in the form of needle-like crystals, known as raphidcs. which can produce painful sensations in the mouth when eaten raw. The effects of oxalic acid in the diet may he twofold. First, it forms strong chelates with dietary calcium, rendering the culcium unavailable for absorption and assimilation. Secondly, absorbed oxalic acid causes assimilated Ca to be precipitated as insoluble salts that accumulate in the renal glomeruli and contribute to the formation of renal calculi. 

The vegetative body is a thallus. It consists of filaments about 5 pm in diameter which are multi-branched or spread over or into the nutrient medium. The filaments or hyphae, can be present without cross walls as in lower fungi or divided into cells by septa in higher fungi. The total hyphal mass of the fungal thallus is called the mycelium. In certain situations during transition between asexual and sexual reproduction, various other tissue structures are formed, e.g. plectrenchyma (mushroom flesh). 

In terms of cultivation parameters and nutrients, the psychotropic species are no different from table mushrooms and other common gilled mushrooms. For that reason, Oss and Oeric s speculations about extra-terrestrial origins of these species clearly belong into the realm of fables. In addition, psilocybin and psilocin are substances that can be derived from tryptophan by means of discemable reactions indeed, the amino acid tryptophan in its free form has been found in a large number of mushroom species. 

Mushrooms—and all living organisms—are in constant competition for available nutrients. In creating a sterile environment, the cultivator seeks to give advantage to the mushroom over the myriad legions of other competitors. Before culture work can begin, the first step is the construction of an inoculation chamber or sterile laboratory. 

As myceiium grows out on a nutrient agar, it can display a remarkable diversity of forms. Some mycelia are fairly uniform in appearance others can be polymorphous at first and then suddenly de- velop into a homogeneous looking mycelia. This is the nature of mushroom mycelia—to constantly and evolve. 

The actua amount of substrate that can be compacted into one square foot of growing area and managed depends upon the cooling capabilities of the control system as well as the outside temperature. Experiments using Tracer elements In mushroom beds three feet deep have shown that nutrients from the farthest point are transported to The growing mushrooms. Yields per sq. ft. Increased although at a lower substrate efficiency.
