Can germinated yam still be eaten? I'll ask an authoritative person to answer. . . Without practice, there is no right to speak. Don't talk nonsense ...

After eating for a few days, I'm in good health now, nothing. When I make hard-core yam, I remove the sprouted part in advance, soak it in water and wash it. I cooked it in an electric pressure cooker. I drank soup. Everything is fine.

Yam and potato are not the same thing According to the origin, taste and shape of potatoes, people give them many interesting names. For example:; China: Shandong Lunan area (Tengzhou) is called Didan, Yunnan Guizhou is called taro or potato, Guangxi is called Pangui thorn potato, Shanxi is called yam egg, Anhui is also called sweet potato, and most northeastern provinces are called potatoes. Potatoes are also called potato, potato, potato, yam egg, steamed egg and potato (commonly known in Hong Kong and Guangzhou). Although potatoes are called "yam eggs" in some areas, there are actually things called yam eggs. So be sure to distinguish clearly and don't misunderstand. Italians call it sweet potato, French call it sweet apple, Germans call it fragrant pear, Americans call it Irish sweet potato, and Russians call it Dutch sweet potato. In view of the confusion of the name, botanists gave it a worldwide scientific name-potato. Potato is one of the vegetables often eaten at family table, but it contains solanin, which is contained in the whole potato plant. However, the content of different parts of mature potatoes is different, which generally does not cause poisoning, while the skin of potato buds, flowers, leaves and tubers contains more solanine, and the toxin in potato buds is even dozens to hundreds of times higher than that in fleshy parts. Immature green potatoes or potato tubers with dark spots due to improper storage contain highly toxic substances.

In order to prevent potato poisoning, we can store potatoes in a dry and cool place to prevent germination. When eating, if you find germination or dark green pulp, you'd better not eat it.

Dioscorea zingiberensis-original plant

Yam tuber is cold-tolerant [1], and can be stored locally if necessary, and the harvest can be delayed until the first half of March of the following year. It can also be stored in an earthen kiln. In the cellar, Chinese herbal medicines and sand are alternately stored in layers. Finally, cover the soil into a ridge shape and cover it with straw to prevent rainwater from invading. The temperature in the cellar 10℃ ~ 15℃ can be stored until April ~ May of the following year. Dioscorea opposita Thunb. tubers are resistant to low temperature during dormancy, and do not show freezing injury for a short time below -4℃. The suitable storage temperature is 0℃ ~ 2℃ and the relative humidity is about 90%.

Name: Yam Latin scientific name: Yam Other names: Yam, Yam, Yam, Yam, Yam, Yam, Yam, Yam, Yam, Yam. Smell: (root) sweet, warm, flat and nontoxic. English names: Nagaimo, Yamaimo, Chinese Yam, Japanese yam, Korean yam; According to "Compendium of Materia Medica", yam was changed into a taboo for potato medicine because Tang Daizong was called Li Yu, and it was changed into a taboo for yam because Song Yingzong was called Zhao Shu. Yam is one of the ingredients of Liuwei Dihuang Pill.

The in vitro experiment of the water extract of Dioscorea opposita shows that it can promote the production of interferon and increase the number of T cells. In the study of experimental arthritis rats, the extract of Dioscorea opposita can significantly inhibit the denaturation of γ globulin by Cu2+, indicating that it has anti-arthritis effect. The water extract of Dioscorea opposita can also eliminate urinary protein and inhibit the production of mutant cells. Yam, formerly known as Dioscorea opposita, can tonify the spleen and stomach yin without stagnation, neither heat nor dryness, while tonifying the lung and kidney can only be used as an auxiliary product. Yam is often used in many anti-aging prescriptions. "Materia Medica Seeking Truth": "Yin nourishing drugs should be used raw, and spleen and lung decocting drugs should be used." "This belongs to food. Although qi is warm but flat, it is yin of spleen and lung. Therefore, it can moisturize fur, increase muscles ... It tastes sweet and salty, and it can also benefit the kidney and strengthen yin. "

processing method

(Note: It is the rhizome of Dioscorea opposita of Dioscoreaceae. ) 1, bloating in the heart, syncope in hands and feet, not thinking about diet. Stir-fried Dioscorea zingiberensis for half a lifetime. Two yuan each time, the rice soup is closed. Take it twice a day. 2, forbidden dysentery. The treatment method is the same as above. 3. More urine. Divide Rhizoma Dioscoreae (boiled with alum) and Poria into powder. Two yuan each time, water delivery. 4. Phlegm is short. Use half a bowl of raw yam (mashed), add half a bowl of sugarcane juice, mix well and drink at one time. 5, the spleen and stomach are weak, not thinking about diet. Use Dioscorea zingiberensis, Atractylodes macrocephala, and seven and a half pieces of ginseng, grind them into powder, add water to make them into paste, and make them into balls as big as adzuki beans. Take forty to fifty capsules each time and send rice soup. 6. Damp-heat deficiency. Divide Rhizoma Dioscoreae and Rhizoma Atractylodis equally, and add rice to make meatball rice soup. 7, swollen poison at the beginning. Divide Chinese yam, castor bean and glutinous rice with mud into equal parts, soak in water, grind and spread evenly. 8, frostbite of hands and feet. There is a piece of yam, which is ground and applied. Roots are used as medicine to nourish and strengthen the body and treat spleen and stomach weakness. , and can also be used as non-staple food and raw materials for brewing. Dioscorea zingiberensis, a plant of Dioscoreaceae, has a horizontal rhizome and looks like ginger, also known as Dioscorea zingiberensis. Take root as medicine. The rhizome of Dioscorea zingiberensis is mainly used to extract diosgenin, which is a good raw material for synthesizing adrenocortical drugs. At present, there are 60 ~ 70 kinds of steroid hormone drugs produced from diosgenin at home and abroad, which are widely used to treat cancer, cardiovascular and cerebrovascular diseases, respiratory diseases, contraceptives and so on. The first yam: the stem is cylindrical, the leaves are triangular oval to triangular oval, and the base is halberd-shaped. The male inflorescence is spike-shaped, not pendulous, and its long axis is mostly sawtooth-shaped. The male flowers are subsessile, and the bracts are triangular-ovate, shorter than the perianth, with 6 perianth segments, ovoid and 6 stamens, which are developing. The female inflorescence is similar to the male inflorescence, and the ovary stigma is 3-lobed. Capsule has three wings, the fruit wings are several times wider, the stalk is short, and there are 2 seeds in each room, and the seeds are placed in the center; The seeds are ovoid, surrounded by thin wings of chestnut shell color, and the wings are about 6 mm wide and vary in width. The flowering period is June-August, and the fruiting period is 8-65438+1October. The second kind of yam: asexual propagation, cylindrical stem, heart-shaped leaves, no flowering, with "yam bean" in the axils of leaves, "yam bean" withered in autumn and winter, and germinated in the following spring. Yam can be used as a vertical greening material for climbing fences in gardens. Tubers are usually eaten as vegetables. Tubers (yam) and bulbils (Reiyoshi) can be used as medicine and can strengthen the spleen. Saponin extracted from Dioscorea zingiberensis is the starting material of steroid hormones. It can be used to synthesize and produce more than 60 kinds of six-grade steroid hormone drugs with anti-inflammatory, analgesic, anesthetic and contraceptive functions, and is widely used to treat many diseases such as heart disease, anti-tumor, rheumatoid disease, serious infection, etc., with thorough treatment, no recurrence and no toxic and side effects. Dioscorea zingiberensis is a wild plant. With the wide application of saponin in medicine, wild resources are decreasing year by year, which is far from meeting the market demand. In Kaixian County, improved varieties of Dioscorea zingiberensis were introduced from 200 1 for artificial cultivation. At present, it has grown to more than 2,000 mu, and in 2004 it can grow to 1 10,000 mu. The precursor resources of Dioscorea zingiberensis are abundant, so it is necessary to invest and introduce advanced processing technology and equipment, and then process the hydrolysate on the spot to extract saponin. To develop Dioscorea zingiberensis as an industry, it is necessary to invest in a leading processing enterprise to promote the development of Dioscorea zingiberensis. There are several tips for eating yam: soak yam in salt water immediately after slicing to prevent oxidation and blackening; Fresh yam will have mucus when it is cut, which is very easy to hurt your hands. You can wash it with water and a little vinegar first, which can reduce mucus. Yam is delicate in texture and sweet in taste. However, the skin of yam is easy to cause skin allergy, so it is best to peel it, and don't touch it with your hands after peeling it. Wash your hands several times at once, or you will tickle. Good yam skin is harmless, with mucus, white fault, more mucus and less water. The skin can be fried or dried to make soup or porridge. Peel and eat to avoid abnormal taste such as tingling. Saponins contained in yam skin or plant alkaloids contained in mucus will make yam allergic and itchy after a few people contact it, so direct contact should be avoided when handling yam. Don't eat yam raw, because there are certain toxins in it. Yam should not be taken with alkaline drugs. Processing method of yam

After cutting off the upper reed head of the dug rhizome of Chinese yam (reserved for seed), wash it with water to remove the sediment, remove the fibrous roots, scrape off the outer skin, soak it in clear water for 24 hours, wash off the mucus, then take it out to dry the surface moisture, put it in a sulfur cabinet and fumigate it to the core (generally 0.4-0.5 kg sulfur per 100kg fresh yam), and then wash it with clear water. Expose to the sun until the skin is slightly dry and hard, and put it in a bamboo basket to suffocate, so as to promote the internal moisture overflow, accelerate drying, and prevent external dryness and internal dampness. Dry it after it is stuffy, and so on until the inside is dry (in case of rainy weather, it can be dried in a charcoal oven). The product is thick, white in color, full in powder, free from moth and mildew, and of high quality. Choose yam to remove smaller individuals. Put it in a sulfur cabinet and smoke it again with a little sulfur. Then put it in a water tank and soak it for 1 ~ 2 days (water will submerge the surface of yam) until it soaks through the heart. Then wash the skin with clear water, put it on a bamboo mat to dry until frost appears on the surface, and rub it when the wet and dry conditions are moderate and the soft and hard conditions are suitable. The specific operation is to put a board with a very smooth surface on a flat desktop. Press it with another board with the same smooth surface and rub it back and forth with a little force until the rhizome is round and firm. After rubbing for 1 time, dry it for 1 hour, then put it in the cylinder, cover it with white cloth for 1 day, and take it out and rub it again. Repeat it many times until it dries. The product is dry, white in color, cylindrical, flat at both ends and 9 in length.
