[edit]Nutrition with
Best with:
Tofu with kelp
Tofu is rich in nutrients, saponin-containing ingredients, can inhibit fat absorption, promote lipolysis, prevent atherosclerosis of the peroxides produced. However, saponin will cause the body of iodine deficiency, and kelp is rich in essential iodine (24 grams of iodine per 100 grams of kelp). Because kelp contains more iodine, can also induce goiter, the two eat together, so that the saponin in the tofu a little more excretion, can make the body iodine elements in a balanced state.
But it should be noted that the kelp is cold, the spleen and stomach cold people avoid eating. Patients suffering from hyperthyroidism should not eat kelp. Pregnant women, lactating mothers should not eat too much kelp, because the iodine in the kelp can enter the fetus (baby) with the blood circulation, causing fetal (baby) thyroid dysfunction.
Sesame with kelp
According to modern nutritional analysis, sesame contains a variety of nutrients needed by the human body, its protein content is more than meat, which is very rich in amino acids, calcium content of milk 2 times. Sesame is richer in fat, up to 54%, there are more lecithin, can prevent premature whitening or loss of hair. It contains vitamin E and other nutrients beneficial to the skin, can improve blood circulation, promote metabolism, received the effect of beauty.
Kelp is rich in calcium and iodine, which helps synthesize thyroxine. These two foods with, not only can beauty, but also delay the role of aging.
Cold sesame kelp is a very nutritious and refreshing cold dish. First 100 grams of sesame seeds to impurities, scrub clean, into the pot, with a small fire slowly fried, when fried to sesame incense, out of the pot to cool. 350 grams of wet kelp washed and cut into silk. Steam the kelp shreds on high heat for 15 minutes, then remove from the pot to cool, add MSG, vinegar, sugar, olive oil and mix well to plate, sprinkle with sesame seeds, mix well to be completed.

Harvesting and Storage
Harvested in summer and fall, fished out of the sea and dried in the sun.
Resource Distribution
1. The natural growth of the distribution range, China is limited to Liaodong and Shandong Peninsula of the fertile sea area. Artificial culture has been extended to the coast of Zhejiang, Fujian, Guangdong and other places. But it is a cold temperate species.
2. It is distributed along the coasts of Zhejiang and Fujian. It is a warm temperate species.
3. China's wakame can be divided into two types: the North Sea type (forma distans Miyabe et Okam.) The algal body is more slender, pinnatifid close to the midribs, the sporophyte has a considerable distance from the leaf. It grows along the coasts of Dalian and Shandong. The forma typica Yendo is the opposite, i.e., the body is shorter, the pinnatifid is shallower, and the sporophyte is close to the leaf. It grows naturally in the sea area of Shengsi Island, Zhejiang Province, and belongs to this type.
Flora and fauna
1. Kombu The olive-brown body of the alga is dark brown after drying. After maturity leathery band-shaped, generally 2-6m long, 20-50cm wide, in the center of the blade there are two parallel longitudinal shallow grooves, two grooves in the middle of the thicker part of the "in the middle part of the", the thickness of about 2-5mm, both sides of the edge of the thinning, and there is a wavy crease, the base of the blade cuneate, the thicker into the stage of the flattened round, there is a terete or flattened round short stalk, the base of the blade cuneate, thick into the stage of the flattened round, under a terete or flattened round short stalk, the base of the blade, the base of the blade, the base of the blade is cuneate. The base of the leaf blade is cuneate, while the thicker stages are oblate, with a short, cylindrical or oblate petiole, 5-15 cm long, consisting of a medulla, a cortex and an epidermis inside the petiole and the leaf blade. Inside the cortex there is a mucus cavity with secretory cells that can secrete mucus to the surface of the leaf body, constituting a gelatinous layer that makes the algal body sticky and slippery and plays a protective role. The medulla consists of many algal filaments, and one end of the algal filament cells is enlarged in the shape of a trumpet tube. The leaf surface is smooth in the juvenile stage of the alga, but the leaf blade appears to be concave and convex in the small kelp stage. In the lower part of the leaf blade of the annual alga, the growth of sporocarps was usually seen, in the form of nearly round patches; in the biennial alga, sporocarps grew on almost all of the leaf blades. The fixation apparatus was composed of forked and branched pseudopodia. The spores mature in the fall.
2. Black Kombu The alga is dark brown to dark brown, leathery, 30-100cm or more in height. Leaf body is flat and broad, slightly thick in the middle, one to two times pinnately parted from both sides, the lobes are long ligulate or longer, slightly wrinkled, the edge is generally coarsely serrate. The petiole is stem-like, cylindrical or slightly compressed, 4-12 cm long, 3-8 mm in diameter, with mucilaginous cavities in the cortical cells of the algal body arranged in a ring, 1-2 layers. The medulla consists of trumpet tube filaments with indefinite orientation. Swarms of zoospores are formed on the central part of the mature thallus and on the surface of the lateral lobes. Fixation apparatus consists of bifurcately branched pseudopodia. The sporangia are formed in early summer, and the spores mature in the fall.
3. Undaria pinnatifida Algae body yellow-brown, soft leathery, 1-2m high, 50-100cm wide, the leaf flattened, the central part of the middle ribs have obvious elevated, the two sides of the thinning and soft, the formation of a majority of pinnate lobes, or the size of the uneven notch, but no serration. The leaf surface is scattered with many small black spots, which are the openings of the mucous cells to the epidermis. At maturity, the lower petiole is flanked on both sides by a fungus-like overlapping folded sporophyte, sticky and fleshy, densely covered with sporangia. The lower end of the petiole is a fixation apparatus composed of forked and branched pseudoroots.

Medicinal Plant Cultivation
Biological Characteristics
Kombu is a cold-water seaweed. Its growth temperature is 0-13℃, with 2-7℃ as the optimal temperature. Kombu photosynthesis requires sufficient light energy, and from the seawater to absorb nutrients, due to the turbidity or transparency of seawater is different, suitable for the growth of the water layer there are different depths, deeper than the tidal line under the 2 ~ 3m, shallow in the surface of the water at a depth of lm (in the seawater in the nitrogen, phosphorus fertilizer can improve the yield of kombu). The growth is good in the sea area where the current is big, but on the contrary, the growth is slow and easy to be infected with diseases. The general current speed of 50 ~ 80cm / s is more appropriate.
Kombu is a kind of plant with obvious alternation of generations, the baby cyst of alga body releases mobile spores, which form gametophyte after germination, the oocyst and spermatophore of the gametophyte combine to form the conidium, and the conidium germinates to produce juvenile sporophyte, and the juvenile sporophyte will be the kombu after asexual reproduction.
Culture technology Although there are many kinds of kelp seedlings, the summer seedlings cultivated in June to July is the main source of kelp culture in China. In the kelp aquaculture sea area to choose the bottom of the rocky reef, pollution-free sea area to build a refrigeration system, water purification from the sea water supply system, and can regulate the light of the glass room structure of the nursery. China's temperature difference between the north and south is large, so should be in June to August, the water temperature rose to 23 ℃ before picking good spores. Select from the sea leaves straight, wide, thick, robust, dark brown color, spore soup and moderate maturity, no rotting individuals for the seed kombucha, moved to the indoor water to continue to cultivate. The water temperature was kept between 13～18℃, natural light was applied, and 400mg/m3 of nitrogen and 520mg/m3 of phosphorus were applied, and the sporocysts were produced on the surface of the leaves after 14d. In order to make it a large number of free spores, can be hung in the shade in a cool place to dry 2 ~ 4h, into the pool, the water temperature of 20 ~ 22 ℃, to stimulate its free spores, and can be attached to bamboo or brown rope made of growth base, and then cultivation. Cultivate the water temperature below 10 ℃, keep more than 10h daily light time, according to the different growth stages through the shading equipment to adjust the amount of light, from 500lx to 3000lx. seedling fertilization, the initial nitrogen 3xl0 a 6, phosphorus 0.15x10 a 6, the middle of the nitrogen 4 x l0 a 6, phosphorus 0.2 x l0 a 6, the late nitrogen 5 x 10 a 6, phosphorus 0.15 x l0 a 6. Regularly replace part of the seawater, and maintain a certain flow rate, so that the hourly replacement of water can reach 1/6 ~ 1/3, to maintain clean water. After 100d or so, the seedlings grow to 1 ~ 2cm long, moved to the sea temporarily, should be timely shade, fertilizer and adjust the water layer, so that the seedlings grow to 10 ~ 15cm can be clamped seedlings, using the "big handle shaking plucking" method of seedling picking, will be clamped in 1.5 ~ 2m long clamping rope on the seedlings. Single clip seedlings with a distance of 2.5 ~ 3cm, cluster clip 2 ~ 3 seedlings for a cluster, cluster spacing 5 ~ 7cm, and then hang the seedling rope on the raft, can be used pendant raising, flat raising, slant raising three forms.
Pest control in the seedling period, mainly green rot, white rot disease and other diseases, by mastering the appropriate density of spore attachment (not too large), improve the light, strengthen the scrubbing, 0.05% or 0.01% ammonium sulphate immersion, can play a role in preventing and controlling the effect. In the breeding period, the initial attention to dense breeding, grow to about 1m for thinning, and according to the different growth period of kombucha, the use of regulating the intensity of light, flushing floating mud, sprinkling ammonium nitrate, ammonium sulfate and other fertilizers, regulating the water layer and other measures to prevent and control the green rot, white rot, punctate white rot disease.

[Edit Paragraph]Cooking Instruction
Kelp is a flavorful food, which can be served cold or in soup. However, before consumption, it should be washed and then soaked, and then the soaking water and kelp together in a pot to make soup to eat. This can be avoided in the water dissolved in mannitol and some vitamins are discarded, thus preserving the effective components of the kelp.
Soak the kelp in water for 2 to 3 hours before cooking, and change the water a few times in between.
In order to ensure that the kelp is tender and tasty, cook it in water for about 15 minutes, not too long.
Don't soak the kelp for a long time before eating
First of all, we need to find out whether the kelp contains "arsenic"? Arsenic, in nature, prevails in the environment and plants, animals, water organisms, especially marine organisms, arsenic has a strong ability to enrich, the general sea fish containing arsenic 1.l mg / kg, lobster 70 mg / kg, kelp 35-40 mg / kg, of course, the different sea areas of different levels of pollution, the arsenic content also varies.
Elemental arsenic is not toxic, arsenic compounds such as oxides, salts and organic compounds are toxic. Arsenic is a trace element of the body, in the body cell metabolism plays a role, but long-term excessive intake can lead to chronic poisoning. Arsenic mainly exists in the form of arsenous acid in the human body, and it is mainly discharged through the kidneys and intestines. The amount of arsenic in the blood of normal people is 0.0064 mg/100 ml, and the amount of arsenic in urine is <0.5 mg/l. The World Health Organization (WHO) has set a provisional maximum allowable concentration (MAC) for arsenic. The World Health Organization (WHO) has set the maximum allowable daily intake of arsenic at 0.05 mg/kg body weight.
Arsenic contamination of food often has the following pathways: ① industrial hazardous substances pollution; ② arsenic-containing pesticide pollution; ③ food processing pollution; ④ container pollution, etc. The seaweed containing arsenic is mainly seawater, and the seawater is the main source of arsenic. And kelp containing arsenic is mainly due to seawater pollution.
So in the consumption of kelp, from a safety point of view, must be washed, kelp after soaking in water, arsenic and arsenic compounds dissolved in the water, the amount of arsenic will be greatly reduced. Soak the water to be more, or change one or two water, as for the soaking time, it is not good to say absolutely, this is with the texture of the kelp and the amount of arsenic has a lot to do with the kelp is more tender, less arsenic-containing soaking time can not be too long.
If the texture of hard, arsenic-containing, soaking time can be relatively long, but because of the amount of arsenic is difficult to identify with the naked eye, therefore, generally speaking, soak for about 6 hours on the line, because soaking time is too long, the nutrients in the kelp, such as water-soluble vitamins, inorganic salts, etc. will also be dissolved in water, the nutritional value will be reduced.

Alias kombu, kelp.
Morphology The alga is brown, long banded, leathery, generally 2-6 meters long and 20-30 centimeters wide. Algae body is obviously divided into fixator, stalk and blade. The solidus is pseudoroot-like, the stalk is thick and short cylindrical, and the upper part of the stalk is a broad and long band-like blade. In the center of the blade there are two parallel shallow grooves, in the middle of the middle band, 2-5 mm thick, in the middle band of the two edges of the thinner wave-like folds. It is also an alga, and the root-like part is just a rhizome that serves as a cement, and the leaf-like part is called a phyllode.
Origin, season in China, Liaoning, Shandong, Jiangsu, Zhejiang, Fujian and the northern coast of Guangdong Province are cultured, wild kelp in the low tide line below the depth of 2-3 meters on the rocks are. Due to the impact of the difference in temperature from north to south, light and other factors, so that the growth of kelp maturity early and late, in the same sea area or the same seedling rope on the kelp, the maturity of its successive, so the harvest period extends from mid-May to the first half of July.
