Corn straw, rice straw, wheat straw, bagasse, rice husk, cottonseed hulls and other plant fibers are all used to produce ethanol.
(2) Extracting potassium sulfate, potassium chloride and potassium carbonate from corn stalk plant ash.
Plant straw contains potassium. At present, the vast rural areas in China still use plant straw as the main fuel, resulting in a large number of plant ash. All the potassium in the straw remains in the form of inorganic salt in plant ash, and its potassium content is about 1%. Potassium can be extracted from plant ash by chemical extraction. Generally, 20 parts of potassium carbonate, 5 parts of potassium sulfate and 2 parts of potassium chloride can be extracted from every 100 part of plant ash. The current market prices of the three are 3,700 yuan/ton, 1.300 yuan/ton and 800 yuan/ton respectively. Making full use of plant ash to extract potassium can not only alleviate the shortage of potassium in the market, but also increase the economic benefits of farmers, killing two birds with one stone.
(3) Weaving corn husks.
During the corn harvest season, peel off the corn husks, the outermost layer is not used, and store them after drying in order to avoid getting wet or damp. Before weaving, corn husks can be smoked with sulfur to make them white. Smoked corn skin is as white as powder, as soft as thread, and the reverse side is shiny. The woven products are bright and beautiful. According to the content to be woven, you can dye the corn husks in different colors, and then weave the corn husks and weave them. Can weave carpets, sun hats, handbags, tapestries and so on.
(4) Making meat with corn starch.
Corn starch is used as raw material, mold and simple chemicals are added, and then it is processed into fibrous solid matter, or various meat flavors can be added, and finally it becomes artificial meat. It is nutritious and easy to digest.
(5) Corn flour artificial eggs.
Corn flour, milk, vitamins, various salts and minerals are processed by a specific process, and the shell is made of non-toxic plastic. It looks like an egg and contains no cholesterol. It is very suitable for the elderly and cardiovascular patients.
Corn kernels contain 73% starch, 8.5% protein, 4.3% fat and high content of vitamins (thiamine, riboflavin, etc. Yellow corn also contains carotene, which can be converted into vitamin A in human body. The calorie per 100 grams of corn is 1527 kilojoules, and the content of calories and fat is higher than that of rice and flour. Generally speaking, the contents of lysine and tryptophan in protein of maize seeds are insufficient, but the content of lysine can be improved by breeding. The oil content of corn germ is 36% ~ 4 1%, and the linoleic acid content is high. It is a high-quality edible oil and can be made into margarine. Corn kernels are mainly used for eating and feeding, and can be cooked, ground or made into puffed food. The nutritional value and digestibility are higher than those of barley, oats and sorghum. The stems, leaves and spikes harvested at the wax maturity stage are tender and juicy, rich in nutrition and less in crude fiber, which is a good silage for dairy cows. Corn can be used to produce alcohol, beer, acetaldehyde, acetic acid, acetone, butanol and so on. The syrup made of corn starch is colorless and transparent, with high fructose content. It tastes like honey and sweeter than sucrose. Can be made into high-grade candy, cake, bread, jam and various beverages. In addition, corncob can extract furfural, and straw can be used for papermaking and sound insulation board. Bracts of ear can also be used to weave daily handicrafts.
