Glutinous rice and alkali sand have the functions of enriching blood, invigorating qi and enhancing human immunity.
Glutinous rice is a mild tonic, which has the functions of tonifying deficiency and blood, strengthening spleen and warming stomach, and stopping sweating.
It is suitable for nausea, anorexia and diarrhea caused by spleen and stomach deficiency and cold, sweating, shortness of breath and abdominal distension during pregnancy caused by qi deficiency.
Modern scientific research shows that glutinous rice contains protein, fat, sugar, calcium, phosphorus, iron, vitamin B and starch. It is a warm and strong product.
Can you eat borax and alkali sand in zongzi? number
Borax is usually a white powder containing colorless crystals, which is easily soluble in water. Borax has a wide range of uses, such as cleaning agents, cosmetics, pesticides and so on. It is a raw material for the production of drugs, and it is also a dangerous and toxic chemical raw material. Eating a certain amount of borax can cause poisoning.
Some lawless elements mixed borax into zongzi to make it full in appearance, bright in color, non-stick to zongzi leaves, smooth in hand and stronger in muscle sense.
Since 1992, borax has been banned as a food additive in China.

According to People's Daily Online 2065 438+06 06 06 54 38+0, an old couple who had been selling zongzi for more than ten years in Guangzhou added borax, a non-edible raw material, but they were arrested by the police because they failed to pass the random inspection.
Adding borax to zongzi is about 1.300, which only makes them profit 1.500 yuan. The man was sentenced to one year's imprisonment by Conghua court, and his wife was sentenced to probation. At the same time, I received a "prohibition order": during the probation period, it is forbidden to engage in food sales activities.
This is also the first food safety "prohibition order" issued by Guangzhou Conghua Court.

Is alkali sand poisonous? The chemical formula of alkali sand is K2CO3, which is potassium carbonate, so it is non-toxic.
In addition, making rice cakes requires alkali sand, so it is definitely not poisonous.
Why do you put alkali sand in zongzi? The purpose of balancing alkali sand is to shorten the cooking time of zongzi and make glutinous rice softer and more golden in color.
/kloc-0.000 grams of glutinous rice and 2 grams of alkali is enough.
Soaking glutinous rice for a period of time can also play this role.
In fact, if you use a pressure cooker, you can also soak glutinous rice and zongzi for half a day without alkali, and then put them in the pressure cooker 1.5 hours after wrapping.
Borax is a toxic substance, which can cause damage to brain, liver, kidney and skin and mucous membrane when eaten in a certain amount, and can cause shock in severe cases, so it is not suitable for eating.
The Ministry of Health has banned the addition of sodium tetraborate (borax) to food.
It is understood that borax is usually added in folk jiaozi, because borax has the functions of antisepsis, increasing elasticity and expansion, and according to Ganzhou people, it tastes more chewy.
However, borax enters the human body, becomes boric acid through the action of gastric acid, accumulates in the body, hinders the enzyme action of digestive tract, causes loss of appetite and indigestion, inhibits the absorption of nutrients, promotes fat decomposition, reduces weight, and causes multiple organ accumulation poisoning.
Therefore, it is best not to put borax in making zongzi. If you want to put it, you'd better put it less.
People should not blindly pursue more flexibility and flexibility when choosing food. Nature and health are the most important.
What is the difference between anodic oxidation, sandblasting and alkali sand of aluminum? Please inform us that anodizing is to produce an oxide film on the aluminum surface to prevent corrosion.
Sand blasting is a physical action, which makes the surface of aluminum more delicate and can dilute the extrusion marks.
What is alkali sand? Alkaline sand is potassium carbonate.
Potassium carbonate, white crystalline powder.
The melting point is 89 1℃, the boiling point is decomposed and the relative molecular weight is 138+0.
Soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether.
Strong hygroscopicity, it can absorb carbon dioxide and water when it meets air and convert it into potassium bicarbonate, so it should be sealed and packaged.
Potassium carbonate aqueous solution is alkaline.
Insoluble in ethanol and ether.
Potassium carbonate can be used in glass, printing and dyeing, soap, enamel, preparation of potassium salt and decarbonylation of synthetic ammonia, and can also be used in color TV industry, mainly as a leavening agent in food.
Mainly used for analytical reagents.
Such as high purity analysis, emission spectrum analysis, etc.
It can also be used as a flux for silicate and insoluble sulfate, a water absorbent for organic liquid, electroplating, fertilizer and photography industry.
Extended data
Production methods of potassium carbonate: plant ash method, Niklan method, electrolysis method, ion exchange method, etc.
Commonly used methods are electrolysis and ion exchange.
1 plant ash method
That is, it is extracted from plant ash made of various plant hulls (such as cottonseed hulls, tea seed hulls, tung seed hulls and sunflower seed hulls).
Plant ash contains soluble salts such as potassium carbonate, potassium sulfate and potassium chloride, which can be separated by precipitation and filtration.
2. Electrolysis
The potassium hydroxide solution obtained by electrolyzing potassium chloride is carbonized with carbon dioxide in a carbonization tower.
Evaporating and filtering by a multi-effect evaporator to obtain potassium bicarbonate, and then calcining to obtain the product.
This method is widely used because of the easy availability of raw materials, high utilization rate of potassium and no three wastes, but it consumes more electricity.
3. Ion exchange method
Exchange with cation exchange resin and potassium chloride.
Then eluting with ammonium bicarbonate into dilute solution of potassium bicarbonate, and obtaining the product through multi-effect evaporation, carbonization, crystallization, separation and calcination.
The method has good product quality and short process flow, and is suitable for small-scale production.
